Thank you for choosing this Mitsubishi Inverter.
This Instruction Manual provides instructions for advanced use of the FR-F700 series inverters.
Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction Manual and the Installation
Guideline [IB-0600218ENG] packed with the product carefully to use the equipment to its optimum.
1. Electric Shock Prevention
2. Fire Prevention
3. Injury Prevention
4. Additional Instructions
Also the following points must be noted to prevent an accidental failure,
injury, electric shock, etc.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter
until you have read through Installation Guideline and appended
documents carefully and can use the equipment correctly. Do not
use the inverter until you have a full knowledge of the equipment,
safety information and instructions. In this Instruction Manual, the
safety instruction levels are classified into "WARNING" and
"CAUTION".
Incorrect handling may cause hazardous
conditions, resulting in death or severe
injury.
Incorrect handling may cause hazardous
conditions, resulting in medium or slight
injury, or may cause only material damage.
The level may even lead to a serious consequence
according to conditions. Both instruction levels must be followed
because these are important to personal safety.
•While power is ON or when the inverter is running, do not open
the front cover. Otherwise you may get an electric shock.
•Do not run the inverter with the front cover or wiring cover
removed.
Otherwise you may access the exposed high-voltage terminals
or the charging part of the circuitry and get an electric shock.
•Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits and get an electric shock.
•Before wiring, inspection or switching EMC filter ON/OFF
connector, power must be switched OFF. To confirm that, LED
indication of the operation panel must be checked. (It must be
OFF.) Any person who is involved in wiring, inspection or
switching EMC filter ON/OFF connector shall wait for at least
10 minutes after the power supply has been switched OFF and
check that there are no residual voltage using a tester or the
like. The capacitor is charged with high voltage for some time
after power OFF, and it is dangerous.
•This inverter must be grounded. Grounding must conform to
the requirements of national and local safety regulations and
electrical code (NEC section 250, IEC 536 class 1 and other
applicable standards).
A neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.
•Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
•The inverter must be installed before wiring. Otherwise you
may get an electric shock or be injured.
•Setting dial and key operations must be performed with dry
hands to prevent an electric shock. Otherwise you may get an
electric shock.
•Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an electric
shock.
•Do not replace the cooling fan while power is ON. It is
dangerous to replace the cooling fan while power is ON.
•Do not touch the printed circuit board or handle the cables with
wet hands. Otherwise you may get an electric shock.
•When measuring the main circuit capacitor capacity (Pr. 259
Main circuit capacitor life measuring = "1"), the DC voltage is
applied to the motor for 1s at powering OFF. Never touch the
motor terminal, etc. right after powering OFF to prevent an
electric shock.
WARNING
CAUTION
CAUTION
WARNING
•Inverter must be installed on a nonflammable wall without holes
(so that nobody touches the inverter heatsink on the rear side,
etc.). Mounting it to or near flammable material can cause a fire.
•If the inverter has become faulty, the inverter power must be
switched OFF. A continuous flow of large current could cause a fire.
•Do not connect a resistor directly to the DC terminals P/+ and
N/-. Doing so could cause a fire.
•The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst, damage,
etc. may occur.
•The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
•Polarity must be correct. Otherwise burst, damage, etc. may
occur.
•While power is ON or for some time after power-OFF, do not
touch the inverter since the inverter will be extremely hot.
Doing so can cause burns.
(1) Transportation and installation
•The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to injuries.
•Do not stack the boxes containing inverters higher than the
number recommended.
•The product must be installed to the position where withstands
the weight of the product according to the information in the
Instruction Manual.
•Do not install or operate the inverter if it is damaged or has
parts missing. This can result in breakdowns.
•When carrying the inverter, do not hold it by the front cover or
setting dial; it may fall off or fail.
•Do not stand or rest heavy objects on the product.
•The inverter mounting orientation must be correct.
•Foreign conductive objects must be prevented from entering
the inverter. That includes screws and metal fragments or
other flammable substance such as oil.
•As the inverter is a precision instrument, do not drop or subject
it to impact.
•The inverter must be used under the following environment:
Otherwise the inverter may be damaged.
*1 Temperature applicable for a short time, e.g. in transit.
*2 2.9m/s2 or less for the FR-F740-04320 or more.

(2) Wiring
•Do not install a power factor correction capacitor, surge
suppressor or capacitor type filter on the inverter output side.
These devices on the inverter output side may be overheated
or burn out.
•The connection orientation of the output cables U, V, W to the
motor affects the rotation direction of the motor.
(3) Test operation and adjustment
•Before starting operation, each parameter must be confirmed
and adjusted. A failure to do so may cause some machines to
make unexpected motions.
(4) Operation
•Any person must stay away from the equipment when the retry
function is set as it will restart suddenly after trip.
•Since pressing key may not stop output depending on
the function setting status, separate circuit and switch that
make an emergency stop (power OFF, mechanical brake
operation for emergency stop, etc.) must be provided.
•OFF status of the start signal must be confirmed before
resetting the inverter fault. Resetting inverter alarm with the
start signal ON restarts the motor suddenly.
•The inverter must be used for three-phase induction motors.
Connection of any other electrical equipment to the inverter
output may damage the equipment.
•Do not modify the equipment.
•Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the inverter.
•The electronic thermal relay function does not guarantee
protection of the motor from overheating. It is recommended to
install both an external thermal and PTC thermistor for
overheat protection.
•Do not use a magnetic contactor on the inverter input for
frequent starting/stopping of the inverter. Otherwise the life of
the inverter decreases.
•The effect of electromagnetic interference must be reduced by
using a noise filter or by other means. Otherwise nearby
electronic equipment may be affected.
•Appropriate measures must be taken to suppress harmonics.
Otherwise power supply harmonics from the inverter may heat/
damage the power factor correction capacitor and generator.
•When driving a 400V class motor by the inverter, the motor
must be an insulation-enhanced motor or measures must be
taken to suppress surge voltage. Surge voltage attributable to
the wiring constants may occur at the motor terminals,
deteriorating the insulation of the motor.
•When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting
operations because all parameters return to the initial value.
•The inverter can be easily set for high-speed operation. Before
changing its setting, the performances of the motor and
machine must be fully examined.
•Stop status cannot be hold by the inverter's brake function. In
addition to the inverter's brake function, a holding device must
be installed to ensure safety.
•Before running an inverter which had been stored for a long
period, inspection and test operation must be performed.
•For prevention of damage due to static electricity, nearby metal
must be touched before touching this product to eliminate
static electricity from your body.
CAUTION
CAUTION
WARNING
CAUTION
(5) Emergency stop
•A safety backup such as an emergency brake must be
provided to prevent hazardous condition to the machine and
equipment in case of inverter failure.
•When the breaker on the inverter input side trips, the wiring
must be checked for fault (short circuit), and internal parts of
the inverter for a damage, etc. The cause of the trip must be
identified and removed before turning ON the power of the
breaker.
•When any protective function is activated, appropriate
corrective action must be taken, and the inverter must be reset
before resuming operation.
(6) Maintenance, inspection and parts replacement
•Do not carry out a megger (insulation resistance) test on the
control circuit of the inverter. It will cause a failure.
(7) Disposing of the inverter
•The inverter must be treated as industrial waste.
General instructions

1.2 Inverter and peripheral devices
CAUTION
· Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side. This will
cause the inverter to trip or the capacitor, and surge suppressor to be damaged. If any of the above devices are connected,
immediately remove them.
· Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication
devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to minimize interference.
(Refer topage 15.)
· Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.

Use within the permissible power supply
specifications of the inverter.
The regeneration braking
capability of the inverter can be
exhibited fully.
Install this as required.
Install the magnetic contactor to ensure safety.
Do not use this magnetic contactor to start and
stop the inverter.
Doing so will cause the inverter life to be shorten.
The inverter can be connected
with a computer such as a
programmable controller and
with GOT (human machine
interface).
It supports Mitsubishi inverter
protocol, Modbus-RTU (binary)
protocol and BACnet MS/TP
protocol.
Do not install a power factor correction capacitor,
surge suppressor or EMC filter (capacitor) on the
output side of the inverter.
When installing a moulded case circuit breaker on the
output side of the inverter, contact each manufacturer
for selection of the moulded case circuit breaker.
Power supply harmonics
can be greatly suppressed.
Install this as required.
Greater braking capability
is obtained.
Install this as required.
The breaker must be selected carefully since
an in-rush current flows in the inverter at
power ON.
Install an EMC filter (ferrite
core) to reduce the
electromagnetic noise
generated from the inverter.
Effective in the range from
about 0.5MHz to 5MHz.
A wire should be wound four
turns at a maximum.
: Install these options as required.

Ground
To prevent an electric shock, always ground the
motor and inverter.
For the FR-F720-03160 (FR-
F740-01800) or more, a DC
reactor is supplied.
Always install the reactor.

*2 Compatible with the FR-F720-03160 (FR-F740-01800) or more.
Reactor (FR-HAL, FR-HEL)
Install reactors to suppress harmonics and to
improve the power factor. An AC reactor (FR-HAL)
(option) is required when installing the inverter near
a large power supply system (1000kVA or more).
The inverter may be damaged if you do not use
reactors.
Select the reactor according to the model.
For the FR-F720-02330 (FR-F740-01160) or less,
remove the jumpers across terminals P/+ and P1 to
connect to the DC reactor.
EMC filter
(ferrite core)
(FR-BLF)
The FR-F720-02330
(FR-F740-01160) or
less has a built-in
common mode choke.
(Refer to page 370)
(Refer to page 4)
(Refer to page 4)
(Refer to page 4 )
Inverter
(FR-F700)
The life of the inverter is influenced by surrounding air
temperature. The surrounding air temperature should be
as low as possible within the permissible range. This must
be noted especially when the inverter is installed in an
enclosure. (Refer to page 10)
Wrong wiring might lead to damage of the inverter. The
control signal lines must be kept fully away from the main
circuit to protect them from noise. (Refer to page 14)
Refer to page 15 for the built-in EMC filter.

Installation of the inverter and
enclosure design
1.4 Installation of the inverter and enclosure design
When an inverter enclosure is to be designed and manufactured, heat generated by contained equipment, etc., the
environment of an operating place, and others must be fully considered to determine the enclosure structure, size and
equipment layout. The inverter unit uses many semiconductor devices. To ensure higher reliability and long period of
operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.
1.4.1 Inverter installation environment
As the inverter installation environment should satisfy the standard specifications indicated in the following table,
operation in any place that does not meet these conditions not only deteriorates the performance and life of the
inverter, but also causes a failure. Refer to the following points and take adequate measures.
*1 2.9m/s2 or less for the FR-F740-04320 or more.
(1) Temperature
The permissible surrounding air temperature of the inverter is -10°C (14°F) to +50°C (122°F) (when LD is set) or -10°C
(14°F) to +40°C (104°F) (when SLD is set). Always operate the inverter within this temperature range. Operation outside
this range will considerably shorten the service lives of the semiconductors, parts, capacitors and others. Take the
following measures so that the surrounding air temperature of the inverter falls within the specified range.
1) Measures against high temperature
• Use a forced ventilation system or similar cooling system. (Refer to page 10.)
• Install the enclosure in an air-conditioned electrical chamber.
• Block direct sunlight.
• Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.
• Ventilate the area around the enclosure well.
2) Measures against low temperature
• Provide a space heater in the enclosure.
• Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)
3) Sudden temperature changes
• Select an installation place where temperature does not change suddenly.
• Avoid installing the inverter near the air outlet of an air conditioner.
• If temperature changes are caused by opening/closing of a door, install the inverter away from the door.
(2) Humidity
Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems
of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical
breakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to
85%.
1) Measures against high humidity
• Make the enclosure enclosed, and provide it with a hygroscopic agent.
• Take dry air into the enclosure from outside.
• Provide a space heater in the enclosure.
2) Measures against low humidity
What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity)
beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into
the enclosure from outside.
3) Measures against condensation
Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside-
air temperature changes suddenly.
Condensation causes such faults as reduced insulation and corrosion.
• Take the measures against high humidity in 1).
• Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

Installation of the inverter and
enclosure design

OUTLINE
(3) Dust, dirt, oil mist
Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due
to moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter.
In the atmosphere where conductive powder floats, dust and dirt will cause such faults as malfunction, deteriorated
insulation and short circuit in a short time.
Since oil mist will cause similar conditions, it is necessary to take adequate measures.
Countermeasures
• Place in a totally enclosed enclosure.
Take measures if the in-enclosure temperature rises. (Refer to page 10.)
• Purge air.
Pump clean air from outside to make the in-enclosure pressure higher than the outside-air pressure.
(4) Corrosive gas, salt damage
If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or
the relays and switches will result in poor contact.
In such places, take the measures given in Section (3).
(5) Explosive, flammable gases
As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure.
In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it
structurally complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive
(including the test charges).
The best way is to avoid installation in such places and install the inverter in a non-hazardous place.
(6) Highland
Use the inverter at the altitude of within 1000m (3280.80 feet).
If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate
dielectric strength.
(7) Vibration, impact
The vibration resistance of the inverter is up to 5.9m/s2 (2.9m/s2 for the FR-F740-04320 or more) at 10 to 55Hz
frequency (directions of X, Y, Z axes) and 1mm (0.04 inches) amplitude.
Vibration or impact, if less than the specified value, applied for a long time may make the mechanism loose or cause
poor contact to the connectors.
Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.
Countermeasures
• Provide the enclosure with rubber vibration isolators.
• Strengthen the structure to prevent the enclosure from resonance.
• Install the enclosure away from sources of vibration.

enclosure design
1.4.2 Cooling system types for inverter enclosure
From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps,
resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature
lower than the permissible temperatures of the in-enclosure equipment including the inverter.
The cooling systems are classified as follows in terms of the cooling calculation method.
1) Cooling by natural heat dissipation from the enclosure surface (Totally enclosed type)
2) Cooling by heat sink (Aluminum fin, etc.)
3) Cooling by ventilation (Forced ventilation type, pipe ventilation type)
4) Cooling by heat exchanger or cooler (Heat pipe, cooler, etc.)

(2) Clearances around the inverter
To ensure ease of heat dissipation and maintenance, leave at least the shown clearances around the inverter. At least the
following clearances are required under the inverter as a wiring space, and above the inverter as a heat dissipation space.
(3) Inverter mounting orientation
Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.
(4) Above the inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter
should be heat resistant.
(5) Arrangement of multiple inverters
(6) Placement of ventilation fan and inverter
REMARKS
• For replacing the cooling fan of the FR-F740-04320 or more, 30cm(11.8 inches) of space is necessary in front of
the inverter. Refer to page 360 for fan replacement.
When multiple inverters are placed in the same
enclosure, generally arrange them horizontally as
shown in the right figure (a). When it is inevitable to
arrange them vertically to minimize space, take such
measures as to provide guides since heat from the
bottom inverters can increase the temperatures in
the top inverters, causing inverter failures.
When mounting multiple inverters, fully take caution
not to make the surrounding air temperature of the
inverter higher than the permissible value by
providing ventilation and increasing the enclosure
size. Arrangement of multiple inverters
Heat generated in the inverter is blown up from the bottom of
the unit as warm air by the cooling fan. When installing a
ventilation fan for that heat, determine the place of ventilation
fan installation after fully considering an air flow. (Air passes
through areas of low resistance. Make an airway and airflow
plates to expose the inverter to cool air.)

2.1.2 EMC filter
This inverter is equipped with a built-in EMC filter (capacitive filter) and common mode choke.
The EMC filter is effective for reduction of air-propagated noise on the input side of the inverter.
The EMC filter is factory-set to disable (OFF). To enable it, fit the EMC filter ON/OFF connector to the ON position.
The input side common mode choke, built-in the FR-F720-02330(FR-F740-01160) or less inverter, is always valid
regardless of ON/OFF of the EMC filter ON/OFF connector.
The FR-F720-00046 and 00077 are not provided with the EMC filter ON/OFF connector. (Always ON)
<How to disconnect the connector>
(1) Before removing a front cover, check to make sure that the indication of the inverter operation panel is OFF, wait
for at least 10 minutes after the power supply has been switched OFF, and check that there are no residual voltage
using a tester or the like. (For the front cover removal method, refer to page 6.)
(2) When disconnecting the connector, push the fixing tab and pull the connector straight without pulling the cable or
forcibly pulling the connector with the tab fixed. When installing the connector, also engage the fixing tab securely.
If it is difficult to disconnect the connector, use a pair of long-nose pliers, etc.
CAUTION
⋅Fit the connector to either ON or OFF.
⋅Enabling (turning ON) the EMC filter increase leakage current. (Refer to page 47)
WARNING
While power is ON or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.

Wiring cover and Handling (FR-F720-00930 (FR-F740-00620) or less)
1) Remove the wiring cover of the inverter. Punch out a knockout by firmly tapping it with such as a hammer. Remove
any sharp edges and burrs from knockout holes of the wiring cover.
2) Install conduits and fix with conduits clamps. Pass the cable always through the conduit.
CAUTION
When handling the wiring cover, care must be taken not to cut fingers or hands with sharp edges and burrs.
To avoid wire offcuts and other foreign matter to enter the inverter, conduits must be installed to the all knockout holes.
WARNING
Do not wire without using conduits. Otherwise, the cable sheathes may be scratched by the wiring cover edges,
resulting in a short circuit or ground fault.
REMARKS
⋅When using conduits for the FR-F720-00046 and 00077, fix the conduits to the wiring cover after connecting the earth cable to

(2) Notes on grounding
Always ground the motor and inverter.
1)Purpose of grounding
Generally, an electrical apparatus has an ground terminal, which must be connected to the ground before use.
An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to
manufacture an insulating material that can shut off a leakage current completely, and actually, a slight current
flow into the case. The purpose of grounding the case of an electrical apparatus is to prevent operator from
getting an electric shock from this leakage current when touching it.
To avoid the influence of external noises, this grounding is important to audio equipment, sensors, computers
and other apparatuses that handle low-level signals or operate very fast.
2)Grounding methods and grounding work
As described previously, grounding is roughly classified into an electrical shock prevention type and a noise-
affected malfunction prevention type. Therefore, these two types should be discriminated clearly, and the
following work must be done to prevent the leakage current having the inverter's high frequency components
from entering the malfunction prevention type grounding:
(a) If possible, use (l) independent grounding in figure below for the inverter. If independent grounding is not
available, use (ll) joint grounding in the figure below which the inverter is connected with the other
equipment at a grounding point.
The (lll) common grounding as in the figure below, which inverter shares a common ground cable with the
other equipment, must be avoided.
A leakage current including many high frequency components flows in the ground cables of the inverter
and inverter-driven motor. Therefore, use the independent grounding and separated the grounding cable of
the inverter from equipments sensitive to EMI.
In a high building, it may be effective to use the EMI prevention type grounding connecting to an iron
structure frame, and electric shock prevention type grounding with the independent grounding together.
(b) This inverter must be grounded. Grounding must conform to the requirements of national and local safety
regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards).
A neutral-point grounded power supply for 400V class inverter in compliance with EN standard must be
used.
(c) Use the thickest possible ground cable. The ground cable should be of not less than the size indicated in
the above table on the previous page.
(d) The grounding point should be as near as possible to the inverter, and the grounding wire length should be
as short as possible.
(e) Run the ground cable as far away as possible from the I/O wiring of equipment sensitive to noises and run
them in parallel in the minimum distance.
To be compliant with the EU Directive (Low Voltage Directive), refer to the Installation Guideline.

(3) Total wiring length
The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.
* For the FR-F720-03160 (FR-F740-01800) or more, the setting range of Pr. 72 PWM frequency selection is "0 to 6".
When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.
Take the following measures 1) or 2) in this case. (Refer to page 52)
1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
according to wiring length
2) Connect the surge voltage suppression filter (FR-ASF-H) to the or less andthe sine wave filter (MT-BSL/BSC) to
the or more on the inverter outputside.

(1) Common terminals of the control circuit (SD, 5, SE)
Terminals SD, 5, and SE are all common terminals (0V) for I/O signals and are isolated from each other. Do not
earth(ground) these terminals.
Avoid connecting the terminal SD and 5 and the terminal SE and 5.
Terminal SD is a common terminal for the contact input terminals (STF, STR, STOP, RH, RM, RL, JOG, RT, MRS, RES,
AU, CS).
The open collector circuit is isolated from the internal control circuit by photocoupler.
Terminal 5 is a common terminal for frequency setting signal (terminal 2, 1 or 4), analog current output terminal (CA)
and analog output terminal AM.
It should be protected from external noise using a shielded or twisted cable.
Terminal SE is a common terminal for the open collector output terminal (RUN, SU, OL, IPF, FU).
The contact input circuit is isolated from the internal control circuit by photocoupler.
(2) Signal inputs by contactless switches
The contacted input terminals of the inverter (STF, STR, STOP,
RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be controlled
using a transistor instead of a contacted switch as shown on the

2.3.4 Wiring instructions
1) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals.
If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or
the cables are run improperly, resulting in an operation panel contact fault.
2) The maximum wiring length should be 30m (98.43feet).
3) Use two or more parallel micro-signal contacts or twin contacts to
prevent a contact faults when using contact inputs since the
control circuit input signals are micro-currents.
4) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and
power circuits (including the 200V relay sequence circuit).
5) Do not apply a voltage to the contact input terminals (e.g. STF) of the control circuit.
6) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.

EMC and leakage currents
3.1 EMC and leakage currents
3.1.1 Leakage currents and countermeasures
Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage
current flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation
at the increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following
measures. Select the earth leakage circuit breaker according to its rated sensitivity current, independently of the carrier
frequency setting.
(1) To-ground leakage currents
Leakage currents may flow not only into the inverter's own line but also into the other lines through the ground cable,
etc. These leakage currents may operate ground leakage circuit breakers and earth leakage relays unnecessarily.
Suppression technique
⋅If the carrier frequency setting is high, decrease the Pr. 72 PWM frequency selection setting. Note that motor noise
increases.Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive.
⋅By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and
other line, operation can be performed with the carrier frequency kept high (with low noise).
To-ground leakage currents
⋅Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter
reduces the leakage current.
⋅Increasing the motor capacity increases the leakage current. The leakage current of the 400V class is larger than
that of the 200V class.
(2) Line-to-line leakage currents
Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the
external thermal relay unnecessarily. When the wiring length is long (50m (164.04feet) or more) for the 400V class
small-capacity model (FR-F740-00170 or less), the external thermal relay is likely to operate unnecessarily because
the ratio of the leakage current to the rated motor current increases.
Line-to-line leakage current data example(200V class)
*The leakage currents of the 400V class are about twice as large.
Measures
⋅Use Pr. 9 Electronic thermal O/L relay.
⋅If the carrier frequency setting is high, decrease the Pr. 72 PWM frequency selection setting. Note that motor noise
increases. Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is
protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect
motor temperature.
Installation and selection of moulded case circuit breaker
Install a moulded case circuit breaker (MCCB) on the power receiving side to protect the wiring of the inverter input
side. Select the MCCB according to the inverter input side power factor (which depends on the power supply voltage,
output frequency and load). Especially for a completely electromagnetic MCCB, one of a slightly large capacity must
be selected since its operation characteristic varies with harmonic currents. (Check it in the data of the corresponding
breaker.) As an earth leakage circuit breaker, use the Mitsubishi earth leakage circuit breaker designed for
harmonics and surge suppression.

CAUTION
⋅Install the earth leakage circuit breaker (ELB) on the input side of the inverter.
⋅In the connection earthed-neutral system, the sensitivity current is blunt against an ground fault in the inverter output side.
Grounding must conform to the requirements of national and local safety regulations and electrical codes. (NEC section 250, IEC 536
class 1 and other applicable standards)
⋅When the breaker is installed on the output side of the inverter, it may be unnecessarily operated by harmonics even if the effective
value is less than the rating. In this case, do not install the breaker since the eddy current and hysteresis loss will increase, leading to
temperature rise.

EMC and leakage currents
3.1.2 EMC measures
Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction
peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it
requires the following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate
electromagnetic noises. If these electromagnetic noises cause peripheral devices to malfunction, EMI measures should be
taken to suppress noises. These techniques differ slightly depending on EMI paths.
1) Basic techniques
⋅Do not run the power cables (I/O cables) and signal cables of the inverter in parallel with each other and do not
bundle them.
⋅Use twisted pair shielded cables for the detector connection and control signal cables, and connect the sheathes
of the shield cables to terminal SD.
⋅Ground the inverter, motor, etc. at one point.
2) Techniques to reduce electromagnetic noises that enter and malfunction the inverter (Immunity measures)
When devices that generate many electromagnetic noises (which use magnetic contactors, magnetic brakes, many
relays, for example) are installed near the inverter and the inverter may be malfunctioned by electromagnetic noises,
the following measures must be taken:
⋅Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic
noises.
⋅Fit data line filters to signal cables.
⋅Ground the shields of the detector connection and control signal cables with cable clamp metal.
3) Techniques to reduce electromagnetic noises that are radiated by the inverter to malfunction peripheral devices (EMI
measures)
Inverter-generated electromagnetic noises are largely classified into those radiated by the cables connected to the
inverter and inverter main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of
the peripheral devices close to the main circuit power supply, and those transmitted through the power supply cables.

Propagation Path Measures
1) 2) 3)
When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises,
e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when
their signal cables are run near the inverter, the devices may be malfunctioned by air-propagated
electromagnetic noises. The following measures must be taken:
(1) Install easily affected devices as far away as possible from the inverter.
(2) Run easily affected signal cables as far away as possible from the inverter and its I/O cables.
(3) Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do
not bundle them.
(4) Set the EMC filter ON/OFF connector of the inverter to the ON position. (Refer to page 15)
(5) Insert a common mode filters into I/O and capacitors between the input lines to suppress cable-
radiated noises.
(6) Use shield cables as signal cables and power cables and run them in individual metal conduits to
produce further effects.
4) 5) 6)
When the signal cables are run in parallel with or bundled with the power cables, magnetic and static
induction noises may be propagated to the signal cables to malfunction the devices and the following
measures must be taken:
(1) Install easily affected devices as far away as possible from the inverter.
(2) Run easily affected signal cables as far away as possible from the I/O cables of the inverter.
(3) Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do
not bundle them.
(4) Use shield cables as signal cables and power cables and run them in individual metal conduits to
produce further effects.
7)
When the power supplies of the peripheral devices are connected to the power supply of the inverter in
the same line, inverter-generated noises may flow back through the power supply cables to malfunction
the devices and the following measures must be taken:
(1) Set the EMC filter ON/OFF connector of the inverter to the ON position. (Refer to page 15)
(2) Install the common mode filter (FR-BLF, FR-BSF01) to the power cables (output cable) of the inverter.
8)
When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter, leakage
currents may flow through the ground cable of the inverter to malfunction the device. In such a case,
disconnection of the ground cable of the device may cause the device to operate properly.

EMC and leakage currents
3.1.3 Power supply harmonics
The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power
capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and
transmission path. Take the following countermeasure suppression techniques.
The differences between harmonics and noises are indicated below:
z Measures
Item Harmonics Noise
Frequency Normally number 40 to 50 max.
(3kHz or less) High frequency (several 10kHz to 1GHz order)
Environment To-electric channel, power impedance To-space, distance, wiring path
Quantitative understanding Theoretical calculation possible Random occurrence, quantitative grasping difficult
Generated amount Nearly proportional to load capacity Depending on the current fluctuation ratio (larger as
switching is faster)
Affected equipment immunity Specified in standard per equipment Different depending on maker's equipment
specifications
Suppression example Provide reactor. Increase distance.
The harmonic current generated from the inverter
to the input side differs according to various
conditions such as the wiring impedance, whether
a reactor is used or not, and output frequency and
output current on the load side.
For the output frequency and output current, we
understand that they should be calculated in the
conditions under the rated load at the maximum
operating frequency.
CAUTION
The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by the
high frequency components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent
protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the inverter.
For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

PRECAUTIONS FOR USE OF THE INVERTER
3.2 Installation of a reactor
When the inverter is connected near a large-capacity power transformer (1000kVA or more) or when a power capacitor is to
be switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent
this, always install the AC reactor (FR-HAL)
3.3 Power-OFF and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter input side, it is recommended to provide an MC for the following purposes.
(Refer to page 4 for selection.)
1)To release the inverter from the power supply when the fault occurs or when the drive is not functioning (e.g.
emergency stop operation).
2)
To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure
3)To separate the inverter from the power supply to ensure safe maintenance and inspection work
The inverter's input side MC is used for the above purpose, select class JEM1038-AC3MC for the inverter input side
current when making an emergency stop during normal operation.
(2) Handling of the inverter output side magnetic contactor
Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop.
When the magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter and
such will activate. When an MC is provided to switch to a commercial power supply, for example, it is recommended to
use bypass operation Pr. 135 to Pr. 139 (Refer to page 293).
REMARKS
The wiring length between the FR-HEL and inverter should be 5m maximum and minimized. Use the same wire size as that of the
power supply wire (R/L1, S/L2, T/L3). (Refer to page 21)
REMARKS
Since repeated inrush current at power ON will shorten the life of the converter circuit (switching life is 100 million times (about
500,000 times for FR-F720-01540 or more)), frequent starts/stops must be avoided. Turn ON/OFF the inverter start controlling
terminals (STF, STR) to run/stop the inverter.
• Inverter start/stop circuit example
As shown on the left, always use the start signal
(ON or OFF of STF (STR) signal) to make a start
or stop. (Refer to page 126)
*1 When the power supply is 400V class, install a step-
down transformer.
*2 Connect the power supply terminals R1/L11, S1/L21
of the control circuit to the primary side of the MC to
hold an alarm signal when the inverter's protective
circuit is activated. At this time, remove jumpers
across terminals R/L1 and R1/L11 and S/L2 and S1/
L21. (Refer to page 25 for removal of the jumper.)

Inverter-driven 400V class motor
3.4 Inverter-driven 400V class motor
In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals.
Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is
driven by the inverter, consider the following measures:
z Measures
It is recommended to take either of the following measures:
(1) Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring length
For the 400V class motor, use an insulation-enhanced motor.
Specifically,
1)Specify the "400V class inverter-driven insulation-enhanced motor".
2)For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven,
dedicated motor".
3)Set Pr. 72 PWM frequency selection as indicated below according to the wiring length
(2) Suppressing the surge voltage on the inverter side
Connect the surge voltage suppression filter (FR-ASF-H) to the FR-F720-02330 (FR-F740-01160) or less and the
sine wave filter (MT-BSL/BSC) to the FR-F720-03160 (FR-F740-01800) or more on the inverter output side.
Wiring Length
50m or less 50m to 100m exceeding 100m
Pr. 72 PWM frequency selection 15(14.5kHz) or less 9(9kHz) or less 4(4kHz) or less
CAUTION
· For details of Pr. 72 PWM frequency selection , refer to page 169. (When using an optional sine wave filter (MT-BSL/BSC) for the or
more, set "25" in Pr.72 (2.5kHz).)
· For explanation of surge voltage suppression filter (FR-ASF-H) and sine wave filter (MT-BSL/BSC), refer to the manual of each
option.

Precautions for use of the inverter
3
PRECAUTIONS FOR USE OF THE INVERTER
3.5 Precautions for use of the inverter
The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method
may shorten the product life or damage the product.
Before starting operation, always recheck the following items.
(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform
such wiring.
(3) After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting
holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.
(4) Use cables of the size to make a voltage drop 2% or less.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor
torque to decrease especially at the output of a low frequency.
Refer to page 21 for the recommended cable sizes.
(5) The overall wiring length should be 500m (1640.4 feet) maximum.
Especially for long distance wiring, the fast-response current limit function may decrease or the equipment
connected to the secondary side may malfunction or become faulty under the influence of a charging current due
to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 24.)
(6) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. In this case, set the EMC filter valid to
minimize interference. (Refer to page 15)
(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter
output side.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices is installed, immediately remove it.
(8) For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor.
When accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched
OFF, and then make sure that the voltage across the main circuit terminals P/+ and N/- of the inverter is not more
than 30VDC using a tester, etc.
(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.
· Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by
peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation
resistance may damage the inverter modules.
· Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-ON.
Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.
(10) Do not use the inverter input side magnetic contactor to start/stop the inverter.
Since repeated inrush currents at power ON will shorten the life of the converter circuit (switching life is about
1,000,000 times (about 500,000 times for FR-F720-01540 or more).), frequent starts and stops of the MC must be
avoided. Always use the start signal (ON/OFF of STF and STR signals) to start/stop the inverter. (Refer to page 14)
(11) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity
may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being
connected incorrectly to short terminals 10E and 5.
54
Precautions for use of the inverter
(12) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for bypass operation.
When the wiring is incorrect or if there is an electronic
bypass circuit as shown on the right, the inverter will be
damaged when the power supply is connected to the
inverter U, V, W terminals due to arcs generated at the
time of switch-over or chattering caused by a sequence
error.
(13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor
in the inverter's input side and also make up a sequence which will not switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as
the power is restored.
(14) Inverter input side magnetic contactor (MC)
On the inverter input side, provide MC for the following purposes. (Refer to page 4 for selection.)
1) To release the inverter from the power supply when a fault occurs or when the drive is not functioning (e.g.
emergency stop operation). For example, MC avoids overheat or burnout of the brake resistor when heat
capacity of the resistor is insufficient or brake regenerative transistor is damaged with short while connecting an
optional brake resistor.
2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a
power failure
3) To separate the inverter from the power supply to ensure safe maintenance and inspection work.
The inverter's input side MC is used for the above purpose, select class JEM1038-AC3 MC for the inverter
input side current when making an emergency stop during normal operation.
(15) Handling of inverter output side magnetic contactor
Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop.
When the magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter
and such will activate. When MC is provided for switching to the commercial power supply, for example, switch it
ON/OFF after the inverter and motor have stopped.
(16) Countermeasures against inverter-generated EMI
If electromagnetic noise generated from the inverter causes frequency setting signal to fluctuate and motor
rotation speed to be unstable when changing motor speed with analog signal, the following countermeasures are
effective.
· Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
· Run signal cables as far away as possible from power cables (inverter I/O cables).
· Use shield cables as signal cables.
· Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).
(17) Instructions for overload operation
When performing an operation of frequent start/stop of the inverter, increase/decrease in the temperature of the
transistor element of the inverter may repeat due to a continuous flow of large current, shortening the life from
thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing
bound current, starting current, etc. Decreasing current may increase the life. However, decreasing current will
result in insufficient torque and the inverter may not start. Therefore, increase the inverter capacity to have enough
allowance for current.
(18) Make sure that the specifications and rating match the system requirements.

Failsafe of the system which uses

PRECAUTIONS FOR USE OF THE INVERTER
3.6 Failsafe of the system which uses the inverter
When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter
fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,
provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the
inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,
without using the inverter, is enabled even if the inverter fails.
(1) Interlock method which uses the inverter status output signals
By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be
detected.

1) Check by the output of the inverter fault signal
When the fault occurs and the inverter trips, the fault output
signal (ALM signal) is output (ALM signal is assigned to
terminal A1B1C1 in the initial setting).
Check that the inverter functions properly.
In addition, negative logic can be set (ON when the inverter
is normal, OFF when the fault occurs).
2) Checking the inverter operating status by the inverter
operation ready completion signal
Operation ready signal (RY signal) is output when the
inverter power is ON and the inverter becomes operative.
Check if the RY signal is output after powering ON the
inverter.
3) Checking the inverter operating status by the start signal
input to the inverter and inverter running signal.
The inverter running signal (RUN signal) is output when the
inverter is running (RUN signal is assigned to terminal RUN
in the initial setting).
Check if RUN signal is output when inputting the start signal
to the inverter (forward signal is STF signal and reverse
signal is STR signal). For logic check, note that RUN signal
is output for the period from the inverter decelerates until
output to the motor is stopped, configure a sequence
considering the inverter deceleration time

Failsafe of the system which uses the
inverter
(2) Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure
status of the inverter itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter
fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output
even if an inverter fault occurs.
Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the
backup system such as checking up as below according to the level of importance of the system.
1) Start signal and actual operation check
Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to
the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor
current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the
start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is
recommended to check the three-phase current when using the current detector.
2) Command speed and actual operation check
Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command
and detected speed of the speed detector.
4) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal.
The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor.
Check if Y12 signal is output when inputting the start signal to the inverter (forward signal is STF signal and reverse
signal is STR signal). Note that the current level at which Y12 signal is output is set to 110% of the inverter rated current
in the initial setting, it is necessary to adjust the level to around 20% using no load current of the motor as reference with
Pr.150 Output current detection level.
For logic check, as same as the inverter running signal (RUN signal), the inverter outputs for the period from the inverter
decelerates until output to the motor is stopped, configure a sequence considering the inverter deceleration time.

(1) Starting torque adjustment
⋅On the assumption that Pr. 19 Base frequency voltage is
100%, set the output voltage at 0Hz in % in Pr. 0 (Pr. 46).
⋅ Adjust the parameter little by little (about 0.5%), and check
the motor status each time. If the setting is too large, the
motor will overheat. The guideline is about 10% at the
greatest.
REMARKS
⋅The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 124)
⋅The RT signal is assigned to the RT terminal in the default setting. By setting "3" to any of Pr. 178 to Pr. 189 (Input terminal function
selection), you can assign the RT signal to the other terminal.
CAUTION
⋅Increase the setting when the distance between the inverter and motor is long or when motor torque is insufficient in the low-
speed range. If the setting is too large, an overcurrent trip may occur.
⋅The Pr. 0 and Pr. 46 settings are valid only when V/F control is selected.
⋅When using the inverter dedicated motor (constant-torque motor) with the FR-F720-00250 or 00340 and FR-F740-00126 or
00170, set the torque boost value to 2%. If the initial set Pr. 71 value is changed to the setting for use with a constant-torque
motor, the Pr. 0 setting changes to the corresponding value in above.
⋅Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Please
set parameters after confirming the function of each terminal.

4.3.2 Simple magnetic flux vector control (Pr.80, Pr.90)
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
(1) Automatically control optimum torque (Pr.80)
⋅When Simple magnetic flux vector control is not used, set "9999" (initial value) in Pr.80.
⋅Set the used motor capacity (equal to or one rank higher than the inverter capacity).
(2) Set the motor constant (Pr.90)
⋅Normally setting is not necessary. When you need more torque under Simple magnetic flux vector control for other
manufacturer’s motor, set the motor primary resistance value (R1) for connection. When the setting value is
"9999" (initial value), the motor constant is based on the Mitsubishi motor constant (SF-JR, SF-HRCA).
Providing optimum excitation to the motor can also produce high torque in a low-speed range.

⋅Slip compensation is validated when the motor rated slip calculated by the following formula is set in Pr. 245. Slip
compensation is not used when Pr. 245 = "0" or "9999".
The inverter output current may be used to assume motor slip to keep the motor speed constant.

This function monitors the output current and automatically changes the output frequency to prevent the inverter
from coming to trip due to overcurrent, overvoltage, etc. It can also limit stall prevention and fast-response
current limit operation during acceleration/deceleration, driving or regeneration.
Stall prevention
If the output current exceeds the stall prevention operation level, the output frequency of the inverter is
automatically varied to reduce the output current.
Also the second stall prevention function can restrict the output frequency range in which the stall prevention
function is valid.
Fast-response current limit
If the current exceeds the limit value, the output of the inverter is shut off to prevent an overcurrent.

(1) Setting of stall prevention operation level (Pr. 22)
⋅Set in Pr. 22 the ratio of the output current to the rated inverter current at
which stall prevention operation will be performed. Normally set 110%
(initial value).
⋅Stall prevention operation stops acceleration (makes deceleration) during
acceleration, makes deceleration during constant speed, and stops
deceleration during deceleration.
⋅When stall prevention operation is performed, the OL signal is output.
CAUTION
⋅If an overload status lasts long, an inverter trip (e.g. electronic thermal relay function (E.THM)) may occur.
⋅When Pr. 156 has been set to activate the fast-response current limit (initial setting), the Pr. 22 setting should not be higher than
140%. The torque will not be developed by doing so. (When Pr. 570 = "1")

(2) Stall prevention operation signal output and output timing adjustment (OL signal, Pr. 157)
⋅When the output current exceeds the stall prevention operation level and stall prevention is activated, the stall
prevention operation signal (OL signal) turns ON for longer than 100ms. When the output current falls to or below
the stall prevention operation level, the output signal turns OFF.
⋅Use Pr. 157 OL signal output timer to set whether the OL signal is output immediately or after a preset period of time.
⋅This operation is also performed when the regeneration avoidance function (overvoltage stall) is executed.
(3) Setting of stall prevention operation in high frequency range (Pr. 22, Pr. 23, Pr. 66)
⋅During high-speed operation above the rated motor frequency, acceleration may not be made because the motor
current does not increase. If operation is performed in a high frequency range, the current at motor lockup
becomes smaller than the rated output current of the inverter, and the protective function (OL) is not executed if the
motor is at a stop.
To improve the operating characteristics of the motor in this case, the stall prevention level can be reduced in the
high frequency range. This function is effective for performing operation up to the high-speed range on a centrifugal
separator etc. Normally, set 60Hz in Pr. 66 and 100% in Pr. 23.
⋅Formula for stall prevention operation level
⋅When Pr. 23 Stall prevention operation level compensation factor at double speed = "9999" (initial value), the stall
prevention operation level is kept constant at the Pr. 22 setting up to 400Hz.
Pr. 157 Setting Description

REMARKS
⋅The OL signal is assigned to the terminal OL in the initial setting. The OL signal can also be assigned to the other terminal by
setting "3 (positive logic) or 103 (negative logic)" to any of Pr. 190 to Pr. 196 (output terminal function selection).
CAUTION
· If the frequency has fallen to 0.5Hz by stall prevention operation and remains for 3s, a fault (E.OLT) appears to shutoff the
inverter output.
· Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions.

⋅In Pr. 48, you can set the stall prevention operation level at the output frequency from 0Hz to that set in Pr. 49.
During acceleration, however, the operation level is as set in Pr. 22.
⋅This function can also be used for stop-on-contact or similar operation by decreasing the Pr. 48 setting to weaken the
deceleration torque (stopping torque).
(5) Stall prevention operation level setting by terminal 1 (analog variable) (Pr. 148, Pr. 149)
REMARKS
⋅When Pr. 49 ≠ "9999" (level changed according to frequency) and Pr. 48 = "0%", the stall prevention operation level is 0% at or

(3) Base frequency voltage setting (Pr. 19)
⋅Use Pr. 19 Base frequency voltage to set the base voltage (e.g. rated motor voltage).
⋅If the setting is equal to or less than the power supply voltage, the maximum output voltage of the inverter is as set in
Pr. 19.
⋅Pr. 19 can be utilized in the following cases.
(a) When regeneration frequency is high (e.g. continuous regeneration)
During regeneration, the output voltage becomes higher than the reference and may cause an overcurrent trip
(E.OC) due to an increased motor current.
(b) When power supply voltage variation is large
When the power supply voltage exceeds the rated voltage of the motor, speed variation or motor overheat may
be caused by excessive torque or increased motor current.
CAUTION
⋅When Pr. 71 Applied motor is set to "2" (adjustable 5 points V/F characteristic), the Pr. 47 setting becomes invalid. In addition, you
cannot set "8888" or "9999" in Pr. 19.

PARAMETERS
(1) Remote setting function
⋅Use Pr. 59 to select whether to use the remote setting function or not and whether to use the frequency setting
storage function in the remote setting mode or not.
When Pr. 59 setting is any of "1 to 3, 11 to 13" (remote setting function valid), the functions of the RH, RM and RL
signals are changed to acceleration (RH), deceleration (RM) and clear (RL).
⋅When the remote function is used, the output frequency of the inverter can be compensated for as follows:
External operation ...Frequency set with RH and RM operation + external operation frequency other than multi-
speed (PU operation frequency when Pr.79 = "3" (external, PU combined)) and terminal 4
input
(When making analog input compensation, set "1" to Pr. 28 Multi-speed input compensation
selection.
When Pr. 28 is set to "0" and acceleration/deceleration is made to reach the set frequency of
the analog voltage input (terminal 2 or terminal 4) by RH/RM, the auxiliary input by terminal 1
becomes invalid.)
PU operation............Frequency set by RH/RM operation + PU running frequency
⋅By setting Pr. 59 = "11 to 13", the speed can be decelerated to the frequency lower than the main speed (set by the
external operation frequency (except multi-speed setting) or PU operation frequency).
(2) Frequency setting storage
⋅The frequency setting storage function stores the remotely-set frequency (frequency set by RH/RM operation) into
the memory (EEPROM). When power is switched OFF once, then ON, operation is resumed with the remotely set
frequency. (Pr. 59 =1, 11)
<Frequency setting storage conditions>
⋅The frequency when the start signal (STF or STR) turns OFF
⋅Remotely-set frequency is stored every minute after turning OFF (ON) the RH (acceleration) and RM
(deceleration) signals together. (The frequency is overwritten if the latest frequency is different from the
previous frequency when comparing the two. The state of the RL signal does not affect writing.)
CAUTION
⋅The range of frequency change by RH (acceleration) and RM
(deceleration) is 0 to maximum frequency (Pr. 1 or Pr. 18 setting).
Note that the maximum value of set frequency is (main speed +
maximum frequency).
⋅When the acceleration or deceleration signal switches ON, acceleration/deceleration time is as set in Pr. 44 Second acceleration/
deceleration time and Pr. 45 Second deceleration time. Note that when the time set in Pr. 7 or Pr. 8 is longer than the time set in Pr.
44 or Pr. 45, the acceleration/deceleration time is as set in Pr. 7 or Pr. 8. (when RT signal is OFF)
When the RT signal is ON, acceleration/deceleration is made in the time set to Pr. 44 Second acceleration/deceleration time and Pr.
45 Second deceleration time, regardless of the Pr. 7 or Pr. 8 setting.
⋅Even if the start signal (STF or STR) is OFF, turning ON the acceleration (RH) or deceleration (RM) signal changes the preset
frequency.
⋅When switching the start signal from ON to OFF, or changing frequency by the RH or RM signal frequently, set the frequency
setting value storage function (write to EEPROM) invalid (Pr. 59 ="2, 3, 12, 13"). If set valid (Pr. 59 ="1, 11"), frequency is written
to EEPROM frequently, and this will shorten the life of the EEPROM.
⋅The RH, RM, RL signals can be assigned to the input terminal using any of Pr. 178 to Pr. 189 (input terminal function selection).
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
⋅This parameter can be also used for the Network operation mode.

20 Acceleration/deceleration reference frequency from 0Hz.
⋅Set the acceleration time according to the following formula.

REMARKS
⋅The RT signal acts as the second function selection signal and makes the other second function valid. (Refer to page 125)
⋅The RT signal is assigned to the RT terminal in the default setting. By setting "3" to any of Pr. 178 to Pr. 189 (Input terminal

(1) Starting frequency setting (Pr. 13)
⋅Frequency at start can be set in the range 0 to 60Hz.
⋅You can set the starting frequency at which the start signal is
turned ON.
CAUTION
The inverter will not start if the frequency setting signal is less than the value set in Pr. 13.
For example, when 5Hz is set in Pr. 13, the motor will not start running until the frequency setting signal reaches 5Hz.
(2) Start-time hold function (Pr. 571)
⋅This function holds the output frequency set in Pr. 13 Starting
frequency during the period set in Pr. 571.
⋅This function performs initial excitation to smooth the motor
drive at a start.
CAUTION
⋅When the start signal was turned OFF during start-time hold, deceleration is started at that point.
⋅At switching between forward rotation and reverse rotation, the starting frequency is valid but the start-time hold function is
invalid.
CAUTION
Note that when Pr. 13 is set to any value lower than Pr. 2 Minimum frequency, simply turning ON the start signal
will run the motor at the preset frequency even if the command frequency is not input.

(1) Linear acceleration/ deceleration (
Pr. 29
= "0", initial value)
⋅When the frequency is changed for acceleration, deceleration, etc. in inverter
operation, the output frequency is changed linearly (linear acceleration/
deceleration) to reach the set frequency without straining the motor and
inverter. Linear acceleration/deceleration has a uniform frequency/time slope.
(2) S-pattern acceleration/deceleration A (
Pr. 29
=
"1")
⋅For machine tool spindle applications, etc.
Used when acceleration/deceleration must be made in a short time to a high-
speed range of not lower than the base frequency. In this acceleration/
deceleration pattern, Pr. 3 Base frequency (fb) is the inflection point of the S
pattern and you can set the acceleration/deceleration time appropriate for motor
torque reduction in a constant-power operation range of base frequency (fb) or
higher.
CAUTION

(3) S-pattern acceleration/deceleration B (
Pr. 29
=
"2")
⋅For prevention of load shifting in conveyor and other applications. Since
acceleration/deceleration is always made in an S shape from current
frequency (f2) to target frequency (f1), this function eases shock produced
at acceleration/deceleration and is effective for load collapse prevention,
etc.
(4) Backlash measures (
Pr. 29
=
"3", Pr. 140 to Pr. 143)
⋅What is backlash?
Reduction gears have an engagement gap and have a dead zone
between forward rotation and reverse rotation. This dead zone is called
backlash, and this gap disables a mechanical system from following motor
rotation.
More specifically, a motor shaft develops excessive torque when the
direction of rotation changes or when constant-speed operation shifts to
deceleration, resulting in a sudden motor current increase or regenerative
status.
⋅To avoid backlash, acceleration/deceleration is temporarily stopped.
Set the acceleration/deceleration stopping frequency and time in Pr. 140 to
Pr. 143.
(5) Variable-torque acceleration/deceleration (Pr.29 = "6")
⋅This function is useful for variable-torque load such as a fan and blower to
accelerate/decelerate in short time.
In areas where output frequency > base frequency, the speed
accelerates/decelerates linearly.
CAUTION
Setting the backlash measures increases the acceleration/deceleration time by the stopping time.

REMARKS
⋅When the base frequency is not 45 to 65Hz, the speed accelerates/decelerates
linearly even though Pr. 29 = "6".
⋅Variable-torque acceleration/deceleration overrides Pr. 14 = "1" setting (for variable-
torque load). Thus, when Pr. 14 = "1" while variable-torque acceleration/
deceleration is valid, inverter operates as Pr. 14 = "0" (for constant-torque load).

⋅When multiple motors are operated by a single inverter, protection cannot be provided by the electronic thermal relay function.
Install an external thermal relay to each motor.

(6) PTC thermistor input (PTC signal)
Built-in PTC thermistor of the motor can be input to the PTC signal (AU terminal).
⋅For the terminal used for PTC signal input, assign the function by setting "63" in Pr. 184 AU terminal function selection
and also set the AU/PTC switchover switch to the PTC terminal function. (The initial setting is the AU terminal
function.)
⋅If a motor overheat state is detected for more than 10s according to the input from the PTC thermistor, the inverter
shuts off the output and outputs the PTC thermal fault signal (E.PTC).
PTC thermistor input connection example
⋅The input specifications of the PTC thermistor
are shown on the right.
Motor Temperature PTC Thermistor Resistance Value (Ω)
Normal 0 to 500
Boundary 500 to 4k
Overheat 4k or higher
CAUTION
⋅When the PTC signal was not assigned to Pr. 184 and the AU/PTC switchover switch was set to the PTC terminal function, the
function assigned to the AU terminal is always OFF. Reversely, when the PTC signal was assigned to Pr. 184 and the AU/PTC
switchover switch was set to the AU terminal function, a PTC thermal error (E.PTC) occurs since the function is always in a
motor overheat state.
⋅When you want to input a current, assign the AU signal to the other signal.
⋅Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.

⋅When both of the frequency setting signal and output frequency falls to the frequency set in Pr. 522 or lower, the
inverter stops the output and the motor coasts to a stop.
⋅After a stop, the inverter output re-starts when the frequency signal is set higher than Pr.522 + 2Hz. The motor re-
accelerates at the Pr.13 Starting frequency.
* The output frequency before the slip compensation is compared with the Pr.522 setting.
*1 After a stop, inverter re-starts accelerating at Pr.13 Starting frequency.
*2 The output frequency before the slip compensation is compared with the Pr.522 setting.
*3 Steepness of the slope depends on the acceleration/deceleration time settings such as Pr.7.
The motor coasts to a stop (inverter output shutoff) when inverter output frequency falls to Pr. 522 setting or lower.

PARAMETERS
REMARKS
⋅When Pr. 522 ≠ "9999", output stop function disables DC injection brake operation, so the motor coasts to a stop when the output
frequency falls to Pr. 522 or lower. Re-acceleration during coasting may cause an inverter trip depending on the parameter
setting.
⋅Output stop function is disabled during PID control, JOG operation, and power failure stop.
⋅Output stop function does not operate during reverse rotation deceleration. However, when the frequency setting signal and
output frequency falls to Pr. 522 or lower, the inverter coasts to a stop.
⋅During the output stop due to the output stop function (when forward/reverse command is given, but frequency command is not
given), FWD/REV LED indication on the operation panel flickers fast.

REMARKS
⋅Same function can be assigned to two or more terminals. In this case, the logic of terminal input is OR.
⋅The priorities of the speed commands are in order of jog > multi-speed setting (RH, RM, RL, REX) > PID (X14).
⋅When the X10 signal (FR-HC, MT-HC, FR-CV connection - inverter operation enable signal) is not set or when the PU
operation external interlock (X12) signal is not assigned at the Pr. 79 Operation mode selection setting of "7", the MRS signal
shares this function.
⋅Same signal is used to assign multi-speeds (7 speeds) and remote setting. They cannot be set individually.
(Same signal is used since multi-speed (7 speeds) setting and remote setting are not used to set speed at the same time .)
CAUTION
⋅Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Also
check that wiring is correct, since the terminal name and the signal function became different. Please set parameters after
confirming the function of each terminal.

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
(1) Output shutoff signal (MRS signal)
⋅Turning ON the output shutoff signal (MRS) during inverter running
shuts off the output immediately.
⋅Terminal MRS may be used as described below.
(a) When mechanical brake (e.g. electromagnetic brake) is used to
stop motor
The inverter output is shut off when the mechanical brake
operates.
(b) To provide interlock to disable operation by the inverter
With the MRS signal ON, the inverter cannot be operated if the
start signal is entered into the inverter.
(c) Coast the motor to a stop.
When the start signal is turned OFF, the inverter decelerates the
motor to a stop in the preset deceleration time, but when the MRS
signal is turned ON, the motor coasts to a stop.
(2) MRS signal logic inversion (Pr. 17)
⋅When Pr. 17 is set to "2", the MRS signal (output stop) can be
changed to the normally closed (NC contact) input specification.
When the MRS signal turns ON (opens), the inverter shuts off the
output.
REMARKS
⋅The MRS signal is assigned to the terminal MRS in the initial setting. By setting "24" in either Pr. 178 to Pr. 189 (input terminal

⋅A two-wire type connection is shown below.
⋅In the initial setting, the forward/reverse rotation signals (STF/STR) are used as start and stop signals. Turn ON
either of the forward and reverse rotation signals to start the motor in the corresponding direction. If both are turned
OFF (or ON) during operation, the inverter decelerates to a stop.
⋅The speed setting signal may either be given by entering 0 to 10VDC across the speed setting input terminal 2 and

41 Up-to-frequency sensitivity 10% 0 to 100% Set the level where the SU signal turns ON.
42 Output frequency detection 6Hz 0 to 400Hz Set the frequency where the FU signal turns ON.

50 Second output frequency

870 Speed detection hysteresis 0Hz * 0 to 5Hz Set the hysteresis width for the detected frequency.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
... Specifications differ according to the date assembled. Refer to page 400 to check the SERIAL number.
(1) Up-to-frequency sensitivity (SU signal, Pr. 41)
⋅When the output frequency reaches the set frequency, the up-to-frequency
signal (SU) is output.
⋅The Pr. 41 value can be adjusted within the range ±1% to ±100% on the
assumption that the set frequency is 100%.
⋅This parameter can be used to ensure that the set frequency has been
reached to provide the operation start signal etc. for related equipment.
(2) Output frequency detection (FU signal, FU2
signal, Pr. 42, Pr. 43, Pr. 50)
⋅When the output frequency rises to or above the Pr. 42
setting, the output frequency detection signal (FU) is
output.
⋅This function can be used for electromagnetic brake
operation, open signal, etc.
⋅Frequency detection that is dedicated to reverse
operation can be set by setting detection frequency to Pr.
43. This function is effective for switching the timing of
electromagnetic brake operation between forward
rotation (rise) and reverse rotation (fall) during vertical lift
operation, etc.
⋅When Pr. 43 ≠ "9999", the Pr. 42 setting applies to
forward rotation and the Pr. 43 setting applies to reverse
rotation.
⋅When outputting a frequency detection signal besides
the FU signal, set the detection frequency in Pr. 50. The
FU2 signal output when the output frequency reaches or
exceeds the Pr. 50 setting.
⋅For each signal, assign functions to Pr. 190 to Pr. 196

signals.
When an output frequency fluctuates, the up to frequency
signal (SU) and output frequency detection signals (FU,

to the detected frequency prevents chattering of these
signals.
REMARKS
The output frequency compared with the set frequency changes depending on the control method.

* When Pr. 570 Multiple rating setting = "1", performing inverter reset and all parameter clear changes the initial value and setting
range. (Refer to page 86.)
(1) Output current detection (Y12 signal, Pr. 150, Pr.
151, Pr. 166, Pr. 167)
⋅The output power detection function can be used for excessive
torque detection, etc.
⋅If the output current remains higher than the Pr. 150 setting during
inverter operation for longer than the time set in Pr. 151, the
output current detection signal (Y12) is output from the inverter's
open collector or relay output terminal.
⋅When the Y12 signal turns ON, the ON state is held for the time
set in Pr. 166 .
⋅When Pr. 166 = "9999", the ON state is held until a next start.
⋅At the Pr. 167 setting of "1" or "11", the inverter output is stopped
and the output current detection fault (E.CDO) is displayed when
the Y12 signal turns ON. When a fault stop occurs, the Y12
signal is ON for the time set in Pr. 166 at the Pr. 166 setting of
other than "9999", and remains ON until a reset is made at the Pr.
166 setting of "9999". Setting Pr. 167 = "1" or "11" at Y12 signal
ON does not cause E.CDO. Setting to Pr. 167 becomes effective
after Y12 is turned OFF.
⋅For the X12 signal, set "12 (positive logic)" or "112 (negative
logic)" in any of Pr. 190 to Pr. 196 (output terminal function selection)
and assign the function to the output terminal.

(2) Zero current detection (Y13 signal, Pr. 152, Pr.
153, Pr. 167)
⋅If the output current remains lower than the Pr. 152 setting
during inverter operation for longer than the time set in Pr.
153, the zero current detection (Y13) signal is output from
the inverter's open collector or relay output terminal.
⋅When the inverter's output current falls to "0", torque will not
be generated. This may cause a drop due to gravity when
the inverter is used in vertical lift application. To prevent this,
the output current zero signal (Y13) can be output from the
inverter to close the mechanical brake when the output
current has fallen to "0".
⋅When Pr.167 = "10" or "11", turning Y13 signal ON stops the
inverter output and causes output current detection fault
(E.CDO) to be displayed. ON status of Y13 signal is held for
0.1s at the fault. Setting Pr. 167 = "10" or "11" while Y13
signal is ON does not cause E.CDO. Setting to Pr. 167
becomes effective after Y13 is turned OFF.
⋅For the Y13 signal, set "13 (positive logic)" or "113 (negative
logic)" in any of Pr. 190 to Pr. 196 (output terminal function
selection) to assign the function to the output terminal.
CAUTION
⋅The response time of Y12 and Y13 signals is approximately 0.1s. Note that the response time changes according to the load
condition.
When Pr. 152 = "0", detection is disabled.
⋅Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions.
Please set parameters after confirming the function of each terminal.
CAUTION
The zero current detection level setting should not be too low, and the zero current detection time setting not too
long. Otherwise, the detection signal may not be output when torque is not generated at a low output current.
To prevent the machine and equipment from resulting in hazardous conditions by use of the zero current
detection signal, install a safety backup such as an emergency brake.

⋅The output terminal can be turned ON/OFF depending
on the Pr. 496 or Pr. 497 setting. The remote output

communication from the PU connector or RS-485 port
or by communication from the communication option.
⋅Set "96" (positive logic) or "196" (negative logic) in any

and assign the remote output (REM) signal to the
terminal used for remote output,
⋅When you refer to the left diagram and set 1 to the
terminal bit (terminal where the REM signal has been
assigned) of Pr. 496 or Pr. 497, the output terminal
turns ON (OFF for negative logic). By setting 0, the
output terminal turns OFF (ON for negative logic).
Example)When "96" (positive logic) is set to Pr. 190 RUN terminal function selection and "1" (H01) is set to Pr. 496,
the terminal RUN turns ON.
⋅
When

When
Pr. 495

However, it is not stored when the inverter is reset (terminal
reset, reset request through communication).
(See the chart on the left)
⋅
When
Pr. 495
= "10, 11", the signal during reset is held even an
inverter reset is made.
REMARKS
⋅The output terminal where the REM signal is not assigned using any of Pr. 190 to Pr. 196 does not turn ON/OFF if 0/1 is set to
the terminal bit of Pr. 496 or Pr. 497. (It turns ON/OFF with the assigned function.)
CAUTION
⋅When Pr. 495="1, 11"(remote output data retention at power OFF), connect R1/11 with P/+, and S1/L21 with N/- so that the
control power is retained. If you do not take such a step, the output signals provided after power-ON are not guaranteed.

4.10.9 Pulse train output of output power (Y79 signal, Pr. 799)
(1) Pulse increment setting for output power (Y79 signal, Pr.799)
⋅After power ON or inverter reset, output signal (Y79 signal) is output in pulses every time accumulated output
power of the inverter exceeds Pr.799 Pulse increment setting for output power.
⋅The inverter continues to count the output power at activation of retry function or at an automatic restart after
instantaneous power failure (power failure that is too short to cause an inverter reset). It does not clear the output
power.
⋅If power failure occurs, output power is counted from 0kWh again.
⋅Assign pulse output of output power (Y79: setting value 79 (positive logic), 179 (negative logic)) to any of Pr.190 to
Pr.196 (Output terminal function selection).
After power ON or inverter reset, output signal (Y79 signal) is output in pulses every time accumulated output
power, which is counted after the Pr.799 Pulse increment setting for output power is set, reaches the specified value
(or its integral multiples).

Pulse train output of output power (Y79) is output in
pulses at every output power (kWh) that is specified.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
....Specifications differ according to the date assembled. Refer to page 400 to check the SERIAL number.
CAUTION
⋅Because the accumulated data in the inverter is cleared when control power is lost by power failure or at an inverter reset, the
value on the monitor cannot be used to charge electricity bill.
⋅Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Please set
parameters after confirming the function of each terminal. (Refer to page 128)
REMARKS
⋅When parameter copy is performed, Pr.799 = "9999" might be set. However, the inverter operates as Pr.799 were at "1kWh"

PARAMETERS
(1) Automatic restart after instantaneous power failure operation
⋅When Instantaneous power failure protection (E.IPF) and undervoltage
protection (E.UVT) are activated, the inverter output is shut off. (Refer to
page 340 for E.IPF and E.UVT.)
When automatic restart after instantaneous power failure operation is set,
the motor can be restarted if power is restored after an instantaneous
power failure and under voltage. (E.IPF and E.UVT are not activated.)
⋅When E.IPF and E.UVT are activated, instantaneous power failure/under
voltage signal (IPF) is output.
⋅The IPF signal is assigned to the terminal IPF in the initial setting. The IPF
signal can also be assigned to the other terminal by setting "2 (positive
logic) or 102 (negative logic)" in any of Pr. 190 to Pr. 196 (output terminal
function selection).
(2) Connection (CS signal)
⋅When the automatic restart after instantaneous power failure
selection signal (CS) is turned ON, automatic restart operation
is enabled.
⋅When Pr. 57 is set to other than "9999" (automatic restart
operation enabled), the inverter will not operate if used with the
CS signal remained OFF.
(3) Automatic restart operation selection
(Pr. 162, Pr. 299)
With frequency search
When "0 (initial value), 10" is set in Pr. 162, the inverter
smoothly starts after detecting the motor speed upon power
restoration.
⋅During reverse rotation, the inverter can be restarted smoothly
as the direction of rotation is detected.
⋅You can select whether to make rotation direction detection or
not with Pr. 299 "Rotation direction detection selection at restarting".
When capacities of the motor and inverter differ, set "0" (without
rotation direction detection) in Pr. 299.

REMARKS
⋅Speed detection time (frequency search) changes according to
the motor speed. (maximum 500ms)
⋅When the inverter capacity is two rank or more larger than the
motor capacity, the inverter may not start due to overcurrent
trip (E.OC).
⋅If two or more motors are connected to one inverter, the
inverter functions abnormally. (Inverter does not start properly.)
⋅Since the DC injection brake is operated instantaneously when
the speed is detected at a restart, the speed may reduce if the
moment of inertia of the load is small.
⋅When reverse rotation is detected when Pr. 78="1" (reverse
rotation disabled), the rotation direction is changed to forward
rotation after decelerates in reverse rotation when the start
command is forward rotation. The inverter will not start when
the start command is reverse rotation.

Operation selection at power failure and
instantaneous power failure
(4) Restart coasting time (Pr. 57)
⋅Coasting time is the time from when the motor speed is detected until automatic restart control is started.
⋅Set Pr. 57 to "0" to perform automatic restart operation. The coasting time is automatically set to the value below.
Generally this setting will pose no problems.
⋅Operation may not be performed well depending on the magnitude of the moment of inertia(J) of the load or
operation frequency. Adjust the coasting time between 0.1s and 5s according to the load specifications.
(5) Restart cushion time (Pr. 58)
⋅Cushion time is the length of time taken to raise the voltage appropriate to the detected motor speed (output
frequency prior to instantaneous power failure when Pr. 162 = "1" or "11).
⋅Normally the initial value need not be changed for operation, but adjust it according to the magnitude of the
moment of inertia(J) of the load or torque magnitude.
Without frequency search
When Pr. 162 = "1, 11", automatic restart operation is performed
in a reduced voltage system, where the voltage is gradually
risen with the output frequency unchanged from prior to an
instantaneous power failure independently of the coasting
speed of the motor.
Restart operation at every start
When Pr. 162 = "10" or "11", automatic restart operation is also
performed every start, in addition to the automatic restart after
instantaneous power failure. When Pr. 162 = "0", automatic
restart operation is performed at the first start after power
supply-ON, but not performed at the second time or later.

CAUTION
⋅Changing the terminal assignment using Pr. 178 to Pr. 196 (I/O terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
⋅When automatic restart operation is selected, undervoltage protection (E.UVT) and instantaneous power failure protection
(E.IPF) among the fault output signals will not be provided at occurrence of an instantaneous power failure.
⋅The SU and FU signals are not output during a restart. They are output after the restart cushion time has elapsed.

PARAMETERS
(3) Power failure stop function (Pr. 261 = "1, 21")
⋅If power is restored during power failure deceleration, deceleration to a stop is continued and the inverter remains
stopped. To restart, turn OFF the start signal once, then turn it ON again.
⋅At power failure when Pr. 261 = "21", inverter decelerates to stop automatically by adjusting the deceleration time to
make converter voltage (DC bus) constant. (The setting of Pr. 262 to Pr. 266 are invalid.)
(4) Operation continuation at instantaneous power failure function (Pr. 261 = "2, 22")
⋅When power is restored during deceleration after an instantaneous power failure, acceleration is made again up to
the set frequency.
⋅When this function is used in combination with the automatic restart after instantaneous power failure operation,
deceleration is available at a power failure and acceleration is available again after power restoration. When power
is restored after a stop by deceleration at an instantaneous power failure, automatic restart operation is performed
if automatic restart after instantaneous power failure has been selected (Pr. 57 ≠ "9999")
⋅At power failure when Pr. 261 = "22", inverter decelerates to stop automatically by adjusting the deceleration time to
make converter voltage (DC bus) constant. If the power supply recovers, inverter accelerates again to the set
frequency.
⋅The setting of Pr. 262 to Pr. 266 are invalid when Pr. 261 = "22".
REMARKS
⋅When automatic restart after instantaneous power failure is selected (Pr. 57 ≠ "9999"), deceleration to stop function is invalid and the
restart after instantaneous power failure operation is performed.
⋅When the power failure deceleration stop function is active (Pr. 261 = "1,
21"), the inverter will not start even if the power is turned ON with the
start signal (STF/STR) ON. After switching ON the power supply, turn
OFF the start signal once and then ON again to make a start.

(5) Power failure deceleration signal (Y46 signal)
⋅After a power failure stop, inverter cannot start even if power is restored and the start command is given. In this
case, check the power failure deceleration signal (Y46 signal). (at occurrence of input phase loss protection
(E.ILF), etc.)
⋅The Y46 signal is ON during deceleration at an instantaneous power failure or during a stop after deceleration at an
instantaneous power failure.
⋅For the Y46 signal, set "46 (forward action)" or "146 (reverse action)" in any of Pr. 190 to Pr. 196 (output terminal
function selection) to assign the function.
REMARKS
⋅Stop selection function is disabled while inverter decelerates due to a power failure, even though stop selection (Pr. 250) is set.
CAUTION
⋅When Pr. 30 Regenerative function selection = "2" (FR-HC, MT-HC, FR-CV is used), the power failure deceleration function is
invalid.
⋅When the (output frequency - Pr. 262) at undervoltage or power failure occurrence is negative, the calculation result is regarded
as 0Hz. (DC injection brake operation is performed without deceleration).
⋅During a stop or trip, the power failure stop selection is not performed.
⋅Y46 signal turns on when undervoltage occurs even when the motor is not decelerating at an instantaneous power failure. For
this reason, Y46 signal outputs instantly at powering OFF, which is not a fault.
⋅When power failure deceleration stop function is selected, undervoltage protection (E.UVT), instantaneous power failure
protection (E.IPF), and input phase loss protection (E.ILF) do not function.
⋅Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other terminals. Please
set parameters after confirming the function of each terminal.
CAUTION
Even if the power failure stop function is valid, some loads may cause the inverter to trip and the motor to coast.
The motor will coast if enough regenerative energy is given from the motor.

PARAMETERS
4.13 Operation setting at fault occurrence
4.13.1 Retry function (Pr. 65, Pr. 67 to Pr. 69)
⋅Retry operation automatically resets a fault and
restarts the inverter at the starting frequency when the
time set in Pr. 68 elapses after the inverter is tripped.
⋅Retry operation is performed by setting Pr. 67 to any
value other than "0". Set the number of retries at fault
occurrence in Pr. 67.
⋅When retries fail consecutively more than the number
of times set in Pr. 67, a retry count excess fault (E.RET)
occurs, resulting in inverter trip.
(Refer to retry failure example)
⋅Use Pr. 68 to set the waiting time from when the
inverter trips until a retry is made in the range 0 to 10s.
⋅Reading the Pr. 69 value provides the cumulative
number of successful restart times made by retry. The
cumulative count in Pr. 69 is increased by 1 when a
retry is regarded as successful after normal operation
continues without faults occurring for more than four
times longer than the time set in Pr. 68 after a retry
start.
(When retry is successful, cumulative number of retry
failure is cleared.)
⋅Writing "0" in Pr. 69 clears the cumulative count.
⋅During a retry, the Y64 signal is ON. For the Y64
signal, assign the function by setting "64 (positive
operation)" or "164 (negative operation)" in any of Pr.
190 to Pr. 196 (output terminal function selection) .

⋅Retry is not performed if E.PE (Parameter storage device fault) occurred at power ON.
⋅If a fault that is not selected for a retry occurs during retry operation (retry waiting time), the retry operation stops while the fault
indication is still displayed.
⋅The retry function is invalid for the fault initiated by the fault initiation function.
CAUTION
When you have selected the retry function, stay away from the motor and machine in the case of the inverter is
tripped. The motor and machine will start suddenly (after the reset time has elapsed) after the inverter trip.
When you have selected the retry function, apply in easily visible places the CAUTION stickers supplied.

(1) Output phase loss protection selection (Pr. 251)
⋅When Pr. 251 is set to "0", output phase loss protection (E.LF) becomes invalid.
(2) Input phase loss protection selection (Pr. 872)
⋅When Pr. 872 is set to "1", input phase loss protection (E.ILF) is provided if a phase loss of one phase among the
three phases is detected for 1s continuously.
You can disable the output phase loss protection function that stops the inverter output if one phase of the
inverter output side (load side) three phases (U, V, W) is lost.
The input phase loss protection selection of the inverter input side (R/L1, S/L2, T/L3) can be valid.

REMARKS
If input phase is lost when Pr. 872 = "1" (with input phase loss protection) and Pr. 261 ≠ "0" (power failure stop function valid),
input phase loss protection (E.ILF) is not provided but power-failure deceleration is made.
CAUTION
⋅When an input phase loss occurs in the R/L1 and S/L2 phases, input phase loss protection is not provided but the inverter
output is shut off.
⋅If an input phase loss continues for a long time, the converter section and capacitor lives of the inverter will be shorter.

(1) Energy saving operation mode (Setting "4")
⋅When "4" is set in Pr. 60, the inverter operates in the energy saving operation mode.
⋅In the energy saving operation mode, the inverter automatically controls the output voltage to minimize the inverter
output voltage during a constant operation.
(2) Optimum excitation control mode (Setting "9")
⋅When "9" is set in Pr. 60, the inverter operates in the Optimum excitation control mode.
⋅The Optimum excitation control mode is a control method which controls excitation current to improve the motor

REMARKS
⋅When the motor capacity is too small as compared to the inverter capacity or two or more motors are connected to the inverter,
the energy saving effect is not expected.
CAUTION
⋅When the energy saving mode and Optimum excitation control mode are selected, deceleration time may be longer than the
setting value. Since overvoltage fault tends to occur as compared to the constant-torque load characteristics, set a longer
deceleration time.
⋅Since output voltage is controlled in energy saving operation mode and by Optimum excitation control, output current may

⋅Since four digits are displayed on the operation panel (FR-DU07), the value is displayed in 0.1 increments when a monitor value
in 0.01 increments exceeds 99.99, then rounded up to 100.0. The maximum display is "9999".
⋅As the operation panel (FR-PU04/FR-PU07) is 5-digit display, it displays in 0.1 increments since a carry occurs, e.g. "1000.0",
when a monitor value in 0.01 increments exceeds "999.99". The maximum display is "99999".
⋅The upper limit of communication (RS-485 communication, communication option) is "65535" when Pr. 898 Power saving cumulative

(2) Power saving instantaneous monitor ( 1) power savings, 2) power saving rate )
⋅On the power saving monitor ( 1)), an energy saving effect as compared to the power consumption during
commercial power supply operation (estimated value) is calculated and displays on the main monitor.
⋅In the following case, the power saving monitor ( 1)) is "0".
(a)Calculated values of the power saving monitor are negative values.
(b)During the DC injection brake operation
(c)Motor is not connected (output current monitor is 0A)
⋅On the power saving rate monitor ( 2)), setting "0" in Pr. 895 Power saving rate reference value displays the power
saving rate on the assumption that power (estimated value) during commercial power supply operation is 100%.
When Pr. 895 = "1", the power saving rate on the assumption that the Pr. 893 Energy saving monitor reference (motor
capacity) value is 100% is displayed.
(3) Power saving average value monitor ( 3) power saving average value, 4) average power
saving rate average value, 5) power saving amount average value)
⋅Power saving average value monitor is displayed by setting a value other than "9999" in Pr. 897 Power saving
monitor average time.
⋅The power saving average value monitor ( 3)) displays the unit time average value of the power saving amount at
averaging.
⋅The average value is updated every time an average time has elapsed after the Pr. 897 setting is changed, power is
turned ON or the inverter is reset, assuming as a starting point. The power savings average value update timing
signal (Y92) is inverted every time the average value is updated.
⋅The power saving average value monitor ( 4)) displays the average value per unit time of power saving rate ( 2)) at
every average time by setting "0" or "1" in Pr. 895 Power saving rate reference value.
⋅By setting the charge (power unit) per 1kWh of power amount in Pr. 896 Power unit cost, the power saving amount
average value monitor ( 5)) displays the charge relative to the power saving average value (power saving average
value ( 3)) × Pr. 896).
(4) Cumulative saving power monitor ( 6) power saving amount, 7) power saving amount
charge, 8) annual power saving amount, 9) annual power saving amount charge)
⋅On the cumulative saving power monitor, the monitor data digit can be shifted to the right by the number of Pr. 891
Cumulative power monitor digit shifted times settings. For example, if the cumulative power value is 1278.56kWh
when Pr. 891 = "2", the PU/DU display is 12.78 (display in 100kWh increments) and the communication data is 12.
If the maximum value is exceeded at Pr. 891 = "0 to 4", the power is clamped at the maximum value, indicating that
a digit shift is necessary. If the maximum value exceeded at Pr. 891 = "9999", the power returns to 0 and is
recounted. The other monitors are clamped at the display maximum value.
⋅The cumulative saving power monitor ( 6)) can measure the power amount during a predetermined period.
Measure according to the following steps
1) Write "9999" or "10" in Pr. 898 Power saving cumulative monitor clear.
2) Write "0" in Pr. 898 at measurement start timing to clear the cumulative saving power monitor value and start
accumulation of power saving.
3) Write "1" in Pr. 898 at measurement end timing to hold the cumulative saving power monitor value.
REMARKS
⋅The cumulative saving power monitor value is stored every hour. Hence, when the power supply is switched OFF within one
hour, and switched ON again, the previously stored monitor value is displayed and accumulation starts. (The cumulative monitor
value may decrease)

(6) Annual power saving amount, power charge (Pr. 899)
⋅By setting the operation time rate [%] (ratio of time when the motor is actually driven by the inverter during a year)
in Pr. 899, the annual energy saving effect can be predicted.
⋅When the operation pattern is predetermined to some degree, the estimated value of the annual power saving
amount can be found by measurement of the power saving amount during a given measurement period.
⋅Refer to the following and set the operation time rate.
1) Predict the average time [h/day] of operation in a day.
2) Find the annual operation days [days/year]. (Monthly average operation days × 12 months)
3) Calculate the annual operation time [h/year] from 1) and 2).
4) Calculate the operation time rate and set it to Pr. 899.
⋅Calculate the annual power saving amount from Pr. 899 Operation time rate (estimated value) and power saving

⋅The annual power saving amount charge can be monitored by setting the power charge per hour in Pr. 896 Power

⋅Operation time rate setting example: When operation is performed for about 21 hours per day and the monthly average
operation days are 16 days
Annual operation time = 21 (h/day) × 16 (days/month) × 12 months = 4032 (h/year)

(1) PWM carrier frequency changing (Pr. 72)
⋅You can change the PWM carrier frequency of the inverter.
⋅Changing the PWM carrier frequency produces an effect on avoiding the resonance frequency of a mechanical system or
motor or on EMI measures or on leakage current reduction caused by the PWM switching.
⋅When using an option sine wave filter (MT-BSL/BSC) for the FR-F720-03160 (FR-F740-01800) or more, set
"25"(2.5kHz) in Pr. 72.
(2) Soft-PWM control (Pr. 240)
⋅Soft-PWM control is a control method that changes the motor noise from a metallic tone into an unoffending
complex tone.
(3) PWM carrier frequency automatic reduction function (Pr. 260)
⋅If continuous operation is performed at 85% or higher of the rated inverter current (the value in the parenthesis on
page 370) with Pr.260 = "1 (initial setting)" and Pr.72 ≥ "3 (inverter carrier frequency is set to 3kHz is higher)," E.THT
(Inverter overload trip) is likely to occur. To avoid that, the carrier frequency is automatically lowered to as low as
2kHz. (Motor noise increases, but not to the point of failure)
⋅When Pr. 260 is set to"0", the carrier frequency becomes constant (Pr. 72 setting) independently of the load, making
the motor sound uniform.
Note that continuous operation should be performed at less than 85% of the inverter rating.

4.15.2 Speed smoothing control (Pr. 653, Pr. 654)
(1) Control block diagram
(2) Setting method
If vibration due to mechanical resonance occurs, set 100% in Pr. 653, run the inverter at the frequency which
generates maximum vibration and check if the vibration will be reduced or not after several seconds.
If effect is not produced, gradually increase the Pr. 653 setting and check the effect repeatedly until the most
effective value is set in Pr. 653.
If vibration becomes large by increasing the Pr. 653 setting, gradually decrease the Pr. 653 setting from 100% to
check the effect in a similar manner.
When the vibrational frequency due to the mechanical resonance (fluctuation of torque, speed, and converter
output voltage) is known using a tester and such, set 1/2 to 1 time of the vibrational frequency to Pr.654. (Setting
vibrational frequency range can suppress the vibration better.)
CAUTION
⋅Decreasing the PWM carrier frequency effect on EMI measures and on leakage current reduction, but increases motor noise.
⋅When Pr. 570 = "0" (initial value), functions of Pr. 260 become invalid. PWM carrier frequency automatically decreases when load
increases. (Refer to page 86.)
⋅When PWM carrier frequency is set to 1kHz or less (Pr. 72≤1), fast-response current limit may function prior to stall prevention
operation due to increase in ripple currents, resulting in insufficient torque. In such case, set fast-response current limit
operation invalid using Pr. 156 Stall prevention operation selection.
♦ Parameters referred to ♦
Pr.156 Stall prevention operation selection Refer to page 81
Vibration due to mechanical resonance influences the inverter control, causing the output current (torque) to be

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 190)
⋅Effective for eliminating noise in the frequency setting circuit.
⋅Increase the filter time constant if steady operation cannot be performed due to noise. A larger setting results in
slower response. (The time constant can be set between approximately 5ms to 1s with the setting of 0 to 8.)
Override connection diagram
⋅Use the override function to change the main speed at a fixed ratio.
⋅Set any of "4, 5, 14, 15" in Pr. 73 to select an override.
⋅When an override is selected, the terminal 1 or terminal 4 is used for the main
speed setting and the terminal 2 for the override signal. (When the main speed of
the terminal 1 or terminal 4 is not input, compensation made by the terminal 2
becomes invalid.)
⋅Using Pr. 252 and Pr. 253, set the override range.
⋅How to find the set frequency for override
Set frequency (Hz) = Main speed set frequency (Hz) ×
Main speed set frequency (Hz): Terminal 1, 4 input, multi-speed setting
Compensation amount (%): Terminal 2 input
Example)When Pr. 73 = "5"
The set frequency changes as shown below according to the
terminal 1 (main speed) and terminal 2 (auxiliary) inputs.
CAUTION
⋅When the Pr. 73 setting was changed, check the voltage/current input switch setting. Different setting may cause a fault, failure
or malfunction. (Refer to page 171 for setting.)
REMARKS
⋅The AU signal must be turned ON to use the terminal 4.
⋅When inputting compensation to multi-speed operation or remote setting, set "1" (compensation made) to Pr. 28 Multi-speed

⋅The "bias" and "gain" functions are used to adjust the
relationship between the input signal entered from
outside the inverter to set the output frequency, e.g. 0
to 5V, 0 to 10V or 0 to 20mADC, and the output

⋅Using Pr. 126, set the output frequency relative to
20mA of the frequency command current (0 to
20mA).
⋅There are three methods to adjust the frequency
setting voltage (current) bias/gain.
(a) Method to adjust any point by application of
voltage (current) to across the terminals 2 and 5
(4 and 5). page 179
(b) Method to adjust any point without application of a

CAUTION
⋅When the terminal 2 is calibrated to change the inclination of the set frequency, the setting of the terminal 1 is also changed.
⋅When a voltage is input to the terminal 1 to make calibration, (terminal 2 (4) analog value + terminal 1 analog value) is the analog
calibration value.
⋅When the voltage/current input specifications were changed using Pr. 73 and Pr. 267, be sure to make calibration.

Minimum frequency Even if the input current decreases, minimum frequency setting clamp is valid. 87
Multi-speed operation
Operation by multiple speed signal has precedence even if input current decreases.
(Frequency is not retained when the input current decreases.)
Operation stops when a multi-speed signal turns OFF.
93
Jog operation
The JOG signal has precedence even during decrease in input current. (Frequency is
not retained when the input current decreases.)
Operation stops when the JOG signal is turned OFF during decrease in input current.
PU/jog operation is enabled during PID control.
At this time, PU/jog operation has precedence during decrease in input current.
95
MRS Output is shut off by the MRS signal even if input current decreases. (The inverter
stops when the MRS signal is turned OFF.) 124
Remote setting
The retained frequency will not change even if remote acceleration/deceleration and
clear are performed during decrease in input current. Reflected at restoration.
Remote setting is invalid under PID control.
98
Retry When retry was successful at error occurrence during decrease in input current,
retained frequency was not cleared and operation continues. 159
Added compensation,
override function
Operation of added compensation (terminal 1) and override compensation (terminal
2) are invalid during decrease in input current. 175
Input filter time
constant
The value before filtering is detected.
When input current decreases, frequency after filtering (average value) is retained. 176
Forward/reverse
rotation prevention Motor rotation direction can be restricted independently of 4mA input check setting. 190
PID control
Although PID operation is stopped when input current decreases, the X14 signal
remains ON. (PID operation is valid.) During the pre-charge operation, the pre-
charge ending level and the pre-charge limit are not applied.
The SLEEP function overrides the operation continuation selection (Pr.573 ≠ "2 or 3").
Even if the 4mA input is lost, the SLEEP function activates. PID operation restarts at
the specified frequency when the cancellation conditions for the SLEEP function are
satisfied.
261
Power failure stop
Even if input current decreases when undervoltage or power failure occurs, the motor
stops according to the setting of power-failure deceleration stop function. E.LCI
occurs if a fault occurs from a stop.
156
Pump function If auxiliary motor switchover conditions of pump function is satisfied even when input
current decreases, motor connection/release operation is performed. 283
Switch-over
When the switchover function is operated, frequency is the same as that of the
retained frequency.
Note that if 4mA input is invalid once in switchover mode, the frequency is not
retained next time.

PARAMETERS
(1) Reset selection
• You can select the enable condition of reset function (RES signal, reset command through communication) input.
• When Pr. 75 is set to any of "1, 3, 15, 17, 101, 103, 115, 117", a reset can be input only when a fault occurs.
(2) Disconnected PU detection
• This function detects that the PU (FR-DU07/FR-PU04/FR-PU07) has been disconnected from the inverter for
longer than 1s and causes the inverter to provide a fault output (E.PUE) and come to trip.
• When Pr. 75 is set to any of "0, 1, 14, 15, 100, 101, 114, 115", operation is continued if the PU is disconnected.
(3) PU stop selection
• In any of the PU operation, External operation and Network operation modes, the motor can be stopped by
pressing of the PU.
• When the inverter is stopped by the PU stop function, " " is displayed. A fault signal is not provided.
• When Pr. 75 is set to any of "0 to 3, 100 to 103", deceleration to a stop by is valid only in the PU operation
mode.
CAUTION
⋅When the reset signal (RES) is input during operation, the motor coasts since the inverter being reset shuts off the output.
Also, the cumulative value of the electronic thermal relay function is cleared.
⋅The reset key of the PU is valid only when a fault occurs, independently of the Pr. 75 setting.
CAUTION
⋅When the PU has been disconnected since before power-ON, it is not judged as a fault.
⋅To make a restart, confirm that the PU is connected and then reset the inverter.
⋅The motor decelerates to a stop when the PU is disconnected during PU Jog operation with Pr. 75 set to any of "0, 1, 14, 15"
(which selects operation is continued if the PU is disconnected).
⋅When RS-485 communication operation is performed through the PU connector, the reset selection/PU stop selection function
is valid but the disconnected PU detection function is invalid.
REMARKS
The motor will also decelerate to a stop (PU stop) when is input during operation in the PU mode through RS-485
communication with Pr. 551 PU mode operation command source selection set to "1" (PU mode RS-485 terminals).
188
Misoperation prevention and parameter

(4) How to restart the motor stopped by input from the PU in External operation mode (PU
stop (PS) reset method)
• The motor can be restarted by making a reset using a power supply reset or RES signal.
(5) Reset limit
• Setting can be made for the FR-F720-03160 (FR-F740-01800) or more.
• You can set Pr. 75 to disable reset operation until the thermal cumulative amount reaches 0 when a thermal trip
(THM, THT) or an overcurrent trip (OC1 to OC3) occurs consecutively twice.
• When Pr. 75 = "100 to 103, 114 to 117", reset limit is valid.
(a) When operation panel (FR- DU07) is used
1)After the motor has decelerated to a stop, turn OFF the
STF or STR signal.
2)Push " " three times.
(When Pr. 79 Operation mode selection = "0 (initial value)
or 6") ...( release)
(When Pr. 79 Operation mode selection = "2, 3, or 7"),
pushing " " once will release .
3)Turn ON the STF or STR signal.
(b) Connection of the parameter unit
(FR-PU04/FR-PU07)
1)After the motor has decelerated to a stop, turn OFF the
STF or STR signal.
2)Press .••••••( canceled)
3)Turn ON the STF or STR signal.
CAUTION
⋅Even if Pr. 250 Stop selection is set to other than "9999" to select coasting to a stop, the motor will not coast to a stop but
decelerate to a stop by the PU stop function during external operation.
To restart after the inverter is stopped by PU with PLC function, reset using a power supply rest or RES signal. (sending stop
signal from GX Developer, can also perform the reset.)
CAUTION
Do not reset the inverter with the start signal ON. Doing so will cause the inverter to start immediately after a
reset, leading to hazardous conditions.
REMARKS
When the power-ON reset (no control power is supplied) is made, the thermal cumulative amount is cleared.

Selection of operation mode and
operation location
(1) Operation mode basics
(2) Operation mode switching method
⋅The operation mode specifies the source of the start
command and the frequency command for the
inverter.
⋅Basically, there are following operation modes.
⋅External operation mode: For inputting start
command and frequency command by an external
potentiometer and switches which are connected
to the control circuit terminal.
⋅PU operation mode: For inputting start command
and frequency command by operation panel (FR-
DU07), parameter unit (FR-PU04/FR-PU07) and
RS-485 communication with PU connector.
⋅Network operation mode (NET operation
mode): For inputting start command and
frequency command by RS-485 terminal and
communication options.
⋅The operation mode can be selected from the
operation panel or with the communication
instruction code.
REMARKS
⋅Either "3" or "4" may be set to select the PU/external combined operation, and these settings differ in starting method.
⋅In the initial setting, the stop function by of the PU (FR-DU07/FR-PU07) (PU stop selection) is valid also in other than the
PU operation mode. (Pr. 75 Reset selection/disconnected PU detection/PU stop selection. Refer to page 186.)

Selection of operation mode and

(4) External operation mode (setting "0" (initial value), "2")
(5) PU operation mode (setting "1")
⋅Select the External operation mode when the start
command and the frequency command are applied
from a frequency setting potentiometer, start switch, etc.
externally and connecting them to the control circuit
terminals of the inverter.
⋅Generally, parameter change cannot be performed in
the External operation mode. (Some parameters can be
changed. Refer to the detailed description of each
parameter.)
⋅When "0" or "2" is selected for Pr. 79, the inverter enters
the External operation mode at power ON. (When using
the Network operation mode, refer to page 203.)
⋅When parameter changing is seldom necessary, setting
"2" fixes the operation mode to External operation
mode. When frequent parameter changing is
necessary, setting "0" (initial value) allows the operation
mode to be changed easily to PU operation mode by
pressing of the operation panel. When you
switched to PU operation mode, always return to
External operation mode.
⋅The STF and STR signal are used as a start command,
and the voltage or current signal to terminal 2, 4, multi-
speed signal, JOG signal, etc. are used as frequency
command.
⋅Select the PU operation mode when applying start and
speed command by the key operation of the operation
panel (FR-DU07) or parameter unit (FR-PU04/FR-
PU07) alone. Also select the PU operation mode when
making communication using the PU connector.
⋅When "1" is selected for Pr. 79, the inverter enters the
PU operation mode at power ON. You cannot change to
the other operation mode.
⋅The setting dial of the operation panel can be used for
setting like a potentiometer. (Pr. 161 Frequency setting/key
lock operation selection, refer to page 315.)
⋅When PU operation mode is selected, the PU operation
mode signal (PU) can be output.
For the terminal used for the PU signal output, assign
the function by setting "10 (positive logic) or 110
(negative logic)" in any of Pr. 190 to Pr. 196 (output
terminal function selection).

⋅While continuing operation, you can switch among PU operation, External operation and Network operation (when

(9) PU operation interlock (Setting "7")
⋅The PU operation interlock function is designed to forcibly change the operation mode to External operation mode
when the PU operation interlock signal (X12) input turns OFF. This function prevents the inverter from being
inoperative by the external command if the mode is accidentally left unswitched from the PU operation mode.
⋅Set "7" (PU operation interlock) in Pr. 79.
⋅For the terminal used for X12 signal (PU operation interlock signal) input, set "12" in any of Pr. 178 to Pr. 189 (input
terminal function selection) to assign the function. (Refer to page 122 for Pr. 178 to Pr. 189.)
⋅When the X 12 signal has not been assigned, the function of the MRS signal switches from MRS (output stop) to
the PU operation interlock signal.

the motor is run in External operation mode when the X12 (MRS) signal is turned OFF with either of STF and STR ON.
*2 At fault occurrence, pressing of the operation panel resets the inverter.
CAUTION
⋅If the X12 (MRS) signal is ON, the operation mode cannot be switched to PU operation mode when the start signal (STF, STR) is ON.
⋅When the MRS signal is used as the PU interlock signal, the MRS signal serves as the normal MRS function (output stop) by
turning on the MRS signal and then changing the Pr. 79 value to other than "7" in the PU operation mode. Also as soon as "7"
is set in Pr. 79, the signal acts as the PU interlock signal.
⋅When the MRS signal is used as the PU operation interlock signal, the logic of the signal is as set in Pr. 17. When Pr. 17 = "2",
read ON as OFF and OFF as ON in the above explanation.

⋅Either the RS-485 terminals or communication option can be specified as the command source in Network
operation mode.
⋅For example, set Pr. 550 to "1" when executing parameter write, start command or frequency command from the
inverter RS-485 terminals in the Network operation mode independently of whether the communication option is
connected or not.
(2) Select the command source of the PU operation mode (Pr. 551)
⋅Either the PU connector or RS-485 terminals can be specified as the source in the PU operation mode.
⋅When performing parameter write, giving start command and frequency command from communication with the
RS-485 terminals in PU operation mode, set "1" in Pr. 551.
*1 The Modbus-RTU protocol cannot be used in the PU operation mode. When using the Modbus-RTU protocol, set Pr. 551 to "2".
*2 When the communication option is not fitted, the operation mode cannot be switched to Network operation mode.
When the RS-485 terminals or communication option is used, the external start command and frequency
command can be valid. Also, the command source in the PU operation mode can be selected.

The above parameters can be set when Pr. 160 User group read selection = "0". However, the parameters can be set whenever the communication
option is connected. (Refer to page 190.)
*Pr 550 and Pr. 551 are always write-enabled.
CAUTION
⋅Since Pr. 550 = "9999" (automatic recognition of the communication option) in the initial setting, parameter write, start command
and frequency command cannot be executed by communication using the inverter RS-485 terminals when the communication
option is fitted. (Monitor and parameter read can be performed.)
CAUTION
⋅The PU operation mode has a higher priority when Pr. 550 = "1" (NET mode RS-485 terminals) and Pr. 551 = "1" (PU mode RS-485
terminals). When the communication option is not fitted, therefore, the operation mode cannot be switched to Network operation
mode.

(6) Switching of command source by external terminal (X67)
⋅In Network operation mode, the command source switching signal (X67) can be used to switch the start command
source and speed command source. This signal can be utilized to control the signal input from both the control
terminal and communication.
⋅Set "67" in any of Pr. 178 to Pr. 189 (input terminal function selection) to assign the X67 signal to the control terminal.
⋅When the X67 signal is OFF, the start command source and speed command source are control terminal.
REMARKS
⋅The command source of communication is as set in Pr. 550 and Pr. 551.
⋅The Pr. 338 and Pr. 339 settings can be changed while the inverter is running when Pr. 77 = "2". Note that the setting change is
reflected after the inverter has stopped. Until the inverter has stopped, communication operation command source and
communication speed command source before the setting change are valid.

(Pr. 117 to Pr. 124, Pr. 331 to Pr. 337, Pr. 341, Pr. 549)
[PU connector communication related parameter]
Used to perform required settings for communication between the inverter and personal computer.
There are two different communications: communication using the PU connector of the inverter and
communication using the RS-485 terminals.
You can perform parameter setting, monitor, etc. using the Mitsubishi inverter protocol (computer link
communication), Modbus-RTU protocol and BACnet MS/TP protocol.
To make communication between the personal computer and inverter, initialization of the communication
specifications must be made to the inverter.
Data communication cannot be made if the initial settings are not made or there is any setting error.

*6 The inverter works with the initial parameter setting if a value other than the setting range is set.
...... The specification differs according to the manufacture date. Refer to page 400 and check the SERIAL.
CAUTION
⋅If communication is made without Pr. 336 RS-485 communication check time interval being changed from "0" (initial value), monitor,
parameter read, etc. can be performed, but the inverter results in an alarm as soon as it is switched to the NET operation mode.
If the operation mode at power ON is the Network operation mode, a communication fault (E.SER) occurs after first
communication.
When performing operation or parameter write through communication, set "9999" or more to Pr. 336. (The setting depends on
the computer side program.) (Refer to page 224)
⋅Always reset the inverter after making the initial settings of the parameters. After you have changed the communication-related
parameters, communication cannot be made until the inverter is reset.

4.19.4 Communication EEPROM write selection (Pr. 342)
⋅When changing the parameter values frequently, set "1" in Pr. 342 to write them to the RAM. The life of the EEPROM
will be shorter if parameter write is performed frequently with the setting unchanged from "0 (initial value)" (EEPROM
write).
4.19.5 Operation selection at communication error (Pr.502, Pr.779)
When parameter write is performed from PU connector, RS-485 terminal, and communication option connected
to the inverter, parameter’s storage device can be changed from EEPROM + RAM to only RAM. Set this
parameter when frequent parameter changes are required.

option is connected. (Refer to page 190)
REMARKS
⋅When Pr. 342 is set to "1" (only RAM write), the new values of the parameters will be cleared at power supply-OFF of the inverter.
Therefore, the parameter values available when power is switched ON again are the values stored in EEPROM previously.
For communication using RS-485 terminals or a communication option, operation at a communication error can
be selected. The operation is active under the Network operation mode.

REMARKS
⋅Fault output indicates the fault output signal (ALM signal) and an alarm bit output.
⋅When the fault output setting is active, a fault record is saved in the faults history. (A fault record is written to the faults history at a
fault output. )
When the fault output setting is not active, a fault record is overwritten to the faults history temporarily but not stored.
After the error is removed, the fault indication goes back to normal indication in the monitor, and the faults history goes back to the
previous status.
⋅If Pr. 502 is set to "1, 2, or 3," the normal deceleration time setting (settings like Pr. 8, Pr. 44, and Pr. 45) is applied as the
deceleration time. Normal acceleration time setting (settings like Pr. 7 and Pr. 44) is applied as the acceleration time for restart.
⋅When Pr.502 = "2 or 3," the inverter operates with the start command and the speed command, which were used before the error.
⋅If a communication line error occurs, then the error is removed during deceleration while Pr. 502 = "2," the motor re-accelerates
as soon as the error is removed.
⋅These parameters are valid when communication is performed from the RS-485 terminals or a communication option.
⋅These parameters are valid under the Network operation mode. When performing communication with RS-485 terminals, set Pr.
551
PU mode operation command source selection="2 (initial setting)."
⋅Pr. 502 is valid for the device that has the command source under the Network operation mode. If a communication option is
installed while Pr. 550 = "9999 (initial setting)," a communication error in RS-485 terminals occurs and Pr. 502 becomes invalid.
⋅If the communication error setting is disabled with Pr. 502 = "3," Pr. 335 = "9999," and Pr. 539 = "9999," the inverter does not
continue its operation with the frequency set by Pr. 779 at a communication error.
⋅If a communication error occurs while continuous operation at Pr. 779 is selected with Pr. 502 = "3," the inverter operates at the
frequency set in Pr. 779 even though the speed command source is at the external terminals.
Example) If a communication error occurs while Pr. 339 = "2" and the external terminal RL is ON, the operation is continued at the
frequency set in Pr. 779.

(6) Retry count setting (Pr. 121, Pr. 335)
⋅Set the permissible number of retries at occurrence of a data receive error. (Refer to page 223 for data receive error
for retry)
⋅When data receive errors occur consecutively and exceed the permissible number of retries set, an inverter trip
(E.PUE) may occur and stops the motor.
⋅When "9999" is set, an inverter will not trip even if data receive error occurs but an alarm output signal (LF) is output.
For the terminal used for the LF signal output, assign the function by setting "98 (positive logic) or 198 (negative
logic)" in any of Pr. 190 to Pr. 196 (output terminal function selection).
(7) Signal loss detection (Pr. 122, Pr. 336 RS-485 communication check time interval)
⋅If a signal loss (communication stop) is detected between the inverter and computer as a result of signal loss
detection, a communication fault (PU connector communication: E.PUE, RS-485 terminal communication: E.SER)
occurs and the inverter trips.
⋅Signal loss detection is made when the setting is any of "0.1s" to "999.8s". To make a signal loss detection, it is
necessary to send data (control code refer to page 222) from the computer within the communication check time
interval. (The send data has nothing to do with the station number)
⋅Communication check is started at the first communication in the operation mode having the command source (PU
operation mode for PU connector communication in the initial setting or Network operation mode for RS-485 terminal
communication).
⋅When the setting is "9999", communication check (a signal loss detection) is not made.
⋅When the setting is "0", communication from the PU connector cannot be performed. For communication via the RS-
485 terminals, monitor, parameter read, etc. can be performed, but a communication error (E.SER) occurs as soon
as the inverter is switched to Network operation mode.
REMARKS
When using RS-485 terminal communication, inverter behavior at fault occurrence varies depending on Pr. 502 Stop mode selection
at communication error setting. (Refer to page 216)

PARAMETERS
(8) Instructions for the program
1) When data from the computer has any error, the inverter does not accept that data. Hence, in the user program,
always insert a retry program for data error.
2) All data communication, e.g. run command or monitoring, are started when the computer gives a communication
request. The inverter does not return any data without the computer's request. Hence, design the program so that
the computer gives a data read request for monitoring, etc. as required.

CAUTION
Always set the communication check time interval before starting operation to prevent hazardous conditions.
Data communication is not started automatically but is made only once when the computer provides a
communication request. If communication is disabled during operation due to signal loss etc., the inverter cannot
be stopped. When the communication check time interval has elapsed, the inverter will come to trip (E.PUE,
E.SER). The inverter can be coasted to a stop by switching ON its RES signal or by switching power OFF.
If communication is broken due to signal loss, computer fault etc., the inverter does not detect such a fault. This
should be fully noted.

PARAMETERS
(1) Communication specifications
⋅The communication specifications are given below.
(2) Outline
The Modbus protocol is the communication protocol developed by Modicon for programmable controller.
The Modbus protocol performs serial communication between the master and slave using the dedicated message
frame. The dedicated message frame has the functions that can perform data read and write. Using the functions,
you can read and write the parameter values from the inverter, write the input command of the inverter, and check
the operating status. In this product, the inverter data are classified in the holding register area (register addresses
40001 to 49999). By accessing the assigned holding register address, the master can communicate with the inverter
which is a slave.

REMARKS
There are two different serial transmission modes: ASCII (American Standard Code for Information Interchange) mode and RTU
(Remote Terminal Unit) mode. This product supports only the RTU mode in which 1-byte (8-bit) data is transmitted as-is.
Only the communication protocol is defined by the Modbus protocol, and the physical layer is not stipulated.

Communication operation and setting
(3) Message format
Data check time
1) Query
The master sends a message to the slave (= inverter) at the specified address.
2) Normal Response
After receiving the query from the master, the slave executes the requested function and returns the corresponding
normal response to the master.
3) Error Response
If an invalid function code, address or data is received, the slave returns it to the master.
When a response description is returned, the error code indicating that the request from the master cannot be
executed is added.
No response is returned for the hardware-detected error, frame error and CRC check error.
4) Broadcast
By specifying address 0, the master can send a message to all slaves. All slaves that received the message from the
master execute the requested function. In this communication, the slaves do not return a response to the master.

PARAMETERS
(4) Message frame (protocol)
Communication method
Basically, the master sends a query message (question) and the slave returns a response message
(response). When communication is normal, Device Address and Function Code are copied as they are, and
when communication is abnormal (function code or data code is illegal), bit 7 (= 80h) of Function Code is
turned on and the error code is set to Data Bytes.
The message frame consists of the four message fields as shown above.
By adding the no-data time (T1: Start, End) of 3.5 characters to the beginning and end of the message data,
the slave recognizes it as one message.
Protocol details
The four message fields will be explained below.

Message Field Description
1) ADDRESS field
Is 1 byte long (8 bits), and can be set to any of 0 to 247. Set 0 to send a broadcast message
(all-address instruction) or any of 1 to 247 to send a message to each slave.
When the slave responds, it returns the address set from the master.
The value set to Pr. 331 RS-485 communication station number is the slave address.
2) FUNCTION field
The function code is 1 byte long (8 bits) and can be set to any of 1 to 255. The master sets the
function that it wants to request from the slave, and the slave performs the requested
operation. The following table gives the supported function codes. An error response is
returned if the set function code is other than those in the following table.
When the slave returns a normal response, it returns the function code set by the master.
When the slave returns an error response, it returns H80 + function code.
3) DATA field The format changes depending on the function code (refer to page236). Data includes the byte
count, number of bytes, description of access to the holding register, etc.
4) CRC CHECK field
The received message frame is checked for error. CRC check is performed, and 2 byte long
data is added to the end of the message. When CRC is added to the message, the low-order
byte is added first and is followed by the high-order byte.
The CRC value is calculated by the sending side that adds CRC to the message. The receiving
side recalculates CRC during message receiving, and compares the result of that calculation
and the actual value received in the CRC CHECK field. If these two values do not match, the
result is defined as error.

PARAMETERS
(7) Pr. 343 Communication error count
You can check the cumulative number of communication errors.
(8) Output signal LF "alarm output (communication error warnings)"
During a communication error, the alarm signal (LF signal) is output by open collector output. The LF signal
can be assigned to the output terminal using any of Pr. 190 to Pr. 196 (output terminal function selection).
Parameters Setting Range Minimum Setting Range Initial Value
343 (Read only) 1 0
CAUTION
The number of communication errors is temporarily stored into the RAM. As it is not stored into the EEPROM, performing
a power supply reset or inverter reset clears the value to 0.
CAUTION
Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.

(9) Signal loss detection (Pr. 539 Modbus-RTU communication check time interval)
If a signal loss (communication stop) is detected between the inverter and master as a result of a signal loss
detection, a communication error (E.SER) occurs and the inverter output is shut off.
· When the setting is "9999", communication check (signal loss detection) is not made.
· When the setting value is "0", monitor, parameter read, etc. can be performed. However, a communication error
(E.SER) occurs as soon as the inverter is switched to the Network operation mode.
· A signal loss detection is made when the setting is any of "0.1s to 999.8s". To make a signal loss detection, it is
necessary to send data from the master within the communication check time interval. (The inverter makes
communication check (clearing of communication check counter) regardless of the station number setting of the data
sent from the master.)
· Communication check is started from the first communication after switching to the Network operation mode (use Pr.
551 PU mode operation command source selection to change).
· Communication check time of query communication includes data absence time (3.5 byte).
Since this data absence time differs according to the communication speed, make setting considering this absence
time.
REMARKS
When using RS-485 terminal communication, inverter behaviour at fault occurrence is different depending on Pr. 502 Stop mode
selection at communication error setting. (Refer to page 216)

...... The specification differs according to the manufacture date. Refer to page 400 and check the SERIAL.
Refer to the FR-F700 PLC function programming manual for details of the PLC function.
I/O data read, write, etc. can be performed by accessing the inverter in the predetermined method using special
relays, special registers, etc.
Operation, parameter read/write, etc. can be performed in accordance with the created sequence programs (built
in the inverter) using input data from the control input terminals.
With the output signals, output data can be output to outside the inverter from the control output terminals as not
only the inverter's status signals but also pilot lamp ON/OFF, interlock and other control signals set freely by the
user.

129 *1 PID proportional band 100% 0.1 to 1000%
If the proportional band is narrow (parameter setting is small), the
manipulated variable varies greatly with a slight change of the
measured value. Hence, as the proportional band narrows, the
response sensitivity (gain) improves but the stability deteriorates,
e.g. hunting occurs.
Gain Kp = 1/proportional band
9999 No proportional control
130 *1 PID integral time 1s 0.1 to 3600s
When deviation step is input, time (Ti) is the time required for

proportional (P) action.
As the integral time decreases, the set point is reached earlier but
hunting occurs more easily.
9999 No integral control.

(5) PID control automatic switchover control (Pr. 127)
⋅The inverter can be started up without PID control mode only at a start.
⋅When the frequency is set to Pr. 127 PID control automatic switchover frequency within the range 0 to 400Hz, the
system starts up without PID operation from a start until output frequency is reached Pr. 127, and then it shifts to
PID control operation mode. Once the system has entered PID control operation, it continues PID control if the
output frequency falls to or below Pr. 127.
(6) Selecting operation to be performed at the output of Upper limit signal, Lower limit signal,
and PID deviation limit signal (FUP signal, FDN signal, Y48 signal, Pr.554)
You can select the operation to be performed at the detection of upper, lower and deviation limit for the measured
value input. With Pr. 554 PID signal operation selection, signal output or signal output + alarm stop (E.PID) can be
selected for each of upper limit output signal (FUP signal), lower limit output signal (FDN signal), and PID
deviation limit signal (Y48 signal).

(7) PID output suspension function (SLEEP function) (SLEEP signal, Pr. 554, Pr. 575 to Pr. 577 )
⋅The inverter stops operation if the output frequency after PID control remains at less than the Pr. 576 Output
interruption detection level setting for longer than the time set in Pr. 575 Output interruption detection time. (At this time,
if "0 to 3" is set to Pr. 554 PID signal operation selection, output is shut off (the inverter coasts to stop) when SLEEP
operation starts. If "10 to 13" is set, the inverter decelerates to a stop in the deceleration time set in Pr.8 when
SLEEP operation starts.)
This function can reduce energy consumption in the low-efficiency, low-speed range.
⋅When the deviation (= set value - measured value) reaches the PID output shutoff cancel level (Pr. 577 setting -
1000%) while the PID output suspension function is ON, the PID output suspension function is canceled and PID
control operation is resumed automatically.
⋅While the PID output suspension function is ON, the PID output suspension signal (SLEEP) is output. At this time,
the inverter running signal (RUN) is OFF and the PID control operating signal (PID) is ON.
⋅For the terminal used for the SLEEP signal output, assign the function by setting "70" (positive logic) or "170"
(negative logic) in Pr. 190 to Pr. 196 (output terminal function selection).
* When the output rises to the output interruption cancel level during deceleration to a stop, output interruption gets cancelled, and the inverter
accelerates again to continue PID control. Pr.576 Output interruption detection level is invalid during deceleration.

When the parameter unit is used for operation, input the set point to
Pr. 133.
When performing operation, first set the proportional band (Pr. 129) to a
slightly larger value, the integral time (Pr. 130) to a slightly longer time, and
the differential time (Pr. 134) to "9999" (no function), and while looking at
the system operation, decrease the proportional band (Pr. 129) and
increase the integral time (Pr. 130). For slow response system where a
deadband exists, differential control (Pr. 134) should be turned ON and
increased slowly.
Determine the set point of
what is desired to be adjusted.
Calculate the ratio of the set
point to the detector output.
Input the set point.
To stabilize the measured value,
change the proportional band (Pr.
129) to a larger value, the integral
time (Pr. 130) to a slightly longer
time, and the differential time (Pr.
134) to a slightly shorter time.
While the measured value is stable
throughout the operation status, the
proportional band (Pr. 129) may be
decreased, the integral time (Pr. 130)
decreased, and the differential time
(Pr. 134) increased.
Set the proportional band (Pr.
129) to a slightly larger value,
the integral time (Pr. 130) to a
slightly longer time, and the
differential time (Pr. 134) to
"9999" (no function), and turn
ON the start signal.
Make the following calibration* when the target setting input (0 to 5V) and
detector output (4 to 20mA, 0 to 100%) must be calibrated.
Set the room temperature to 25 C.
Set Pr. 128 and turn ON the X14 signal to enable PID control.
Detector specifications
When 0 C 4mA and 50 C 20mA are used, the set point 25 C is 50%
on the assumption that 4mA is 0% and 20mA is 100%.
(Converting set point to % is unnecessary when both of C42(Pr.934) and
C44(Pr.935) "9999".)
When setting 50% as the set point with voltage input
In the specification of terminal 2, 0V converts to 0% and 5V to 100%.
Thus, set 2.5V for 50% to terminal 2.
When setting 50% as the set point with parameter
Set "50" to Pr.133.
(When both of C42(Pr.934) and C44(Pr.935) are set other than "9999", set
"25" as the set point (no % conversion) directly to the Pr.133.)
*When calibration is required
To perform calibration for detector output and set point input, set calibration parameters Pr. 902 and Pr. 903 (terminal
2), or Pr. 904 and Pr. 905 (terminal 4). However, use Pr. 934 and Pr. 935 instead of Pr. 904 and Pr. 905 when both of C42
(Pr. 934) and C44(Pr. 935) ≠ "9999". Make calibration in the PU mode during an inverter stop.
(For the details of Pr. 902 to Pr. 905, refer to page 177. For the details of Pr. 934 and Pr. 935, refer to page 271.)

4.20.2 Bias and gain calibration for PID displayed values
(Pr. 241, Pr. 759, C42(Pr. 934) to C45(Pr. 935))
(1) Calibration for PID displayed values (C42(Pr. 934) to C45(Pr. 935))
⋅Set PID display bias coefficient for terminal 4 input with C42(Pr. 934).
(Initial value is the coefficient for 4mA.)
⋅Set PID display gain coefficient for 20mA of the frequency command current (4 to 20mA) with C44(Pr. 935).
⋅When both of C42(Pr. 934) and C44(Pr. 935) ≠ "9999" and Pr.133 is set as the set point, the setting of C42(Pr. 934) is
treated as 0%, and C44(Pr. 935) as 100%.
⋅Three methods of bias/gain adjustment for PID displayed values are the following.
(a)Method to adjust any point by application of voltage (current) across the terminals 4 and 5.
(b)Method to adjust any point without application of voltage (current) across terminals 4 and 5.
(c)Method to adjust only the frequency without adjusting the voltage (current).
(For the detail of (a) to (c), refer to page 177.
Make adjustment by assuming C7 (Pr. 905) as C45 (Pr. 935), and Pr. 126 as C44 (Pr. 935).)
⋅When both of C42(Pr. 934) and C44(Pr. 935) ≠ "9999", bias/gain calibration is available for analog value of set
point, measured value, deviation value to perform PID control.
⋅"Bias" / "gain" function can adjust the relation between PID displayed coefficient and measured value input
signal. Examples of measured value input signals are 0 to 5VDC, 0 to 10VDC, or 4 to 20mADC, and they are
externally input.

⋅Take caution when the following condition is satisfied because the inverter recognizes the deviation value as a
negative (positive) value even though a positive (negative) deviation is given:
Pr. 934 PID display bias coefficient > Pr. 935 PID display gain coefficient
To perform a reverse operation, set the forward operation in Pr. 128 PID action selection. To perform a forward
operation, set the reverse operation in Pr. 128. In this case, the PID output shutoff release level is (1000 - Pr. 577).
(Example) Set the following: Pr. 934 = "500" or 20%
(4mA is applied), Pr. 935 = "100" or
100% (20mA is applied).
When the set point=400 and the
measured value=360, the deviation is
+40 (>0), but the inverter recognizes the
deviation with -10% (<0). Because of
this, operation amount does not
increase in the reverse operation
setting.
The operation amount increases when
the forward operation is set.
To perform PID output shutoff release at
deviation of +40 or higher, set Pr. 577 =
"960."
(2) Analog input display unit changing (Pr. 241)
⋅You can change the analog input display unit (%/V, mA) for analog input bias/gain calibration.

This function is to drive the motor at a certain speed before starting PID control. The motor is operated at Pr. 127
PID control automatic switchover frequency at start until a pre-charge ending condition is satisfied. PID control starts
after a pre-charge ending condition is satisfied. (This function is useful for a pump with a long hose. Without this
function, PID control would start before the pump is filled with water, and proper control would not be performed. )
Pre-charge function is also valid for a start after the PID output suspension (SLEEP). PID output suspension

⋅If the X77 or X78 signal is ON at start after the PID output suspension (SLEEP) or the output shutoff cancellation, PID control
starts without performing the pre-charge operation.
⋅PID output suspension (SLEEP) is not performed until the pre-charge operation ends.
⋅During the pre-charge operation, it is regarded as integrated value = estimated value. The motor speed may drop shortly from
the automatic switchover frequency depending on the parameter settings.
⋅Parameter changes and switchover to the second PID control are applied immediately. If PID control has not started when the
settings were changed, PID control starts with changed settings. (If PID control has already started, these settings do not apply.
If the changed settings already satisfy a condition to start PID control, the PID control starts as soon as these are changed. )

(2) Pre-charge protective function
The protective function is activated when the elapsed time or measured amount reaches the set level during the pre-
charge operation. When the level is exceeded, Y51 to Y54 signals are turned ON depending on the control method, the
output is shutoff, and the fault (E.PCH) is output. For Pr. 760 Pre-charge fault selection, select to shutoff the output and
output the fault immediately after a fault occurrence (Pr. 760 = 0), or to output the fault after deceleration to a stop (Pr.
760 = 0). (Pre-charge protective function is effective whether the pre-charge ending conditions are set or not.)
Pre-charge limit level setting is available when the following conditions are satisfied:
⋅Ending time (Pr. 762) < Time limit (Pr. 764)
⋅Ending level (Pr. 761) < Upper detection level (Pr. 763)
REMARKS
When the protective function activates (including during deceleration to stop), Y51 to Y54 signals are kept ON once they are
output whether PID control is valid or invalid. If a fault occurs after deceleration to stop, the fault is output after the stop whether
PID control is valid or invalid.
The output of signal Y51 to Y54 can be released by a reset or the retry operation.
Limit by time
The fault (E.PCH) is output
when the elapsed time reaches
Pr. 764 Pre-charge time limit. With
Pr. 760 Pre-charge fault selection,
you can select to shut off the
output and output the fault
immediately after E.PCH, or to
output the fault after

Retry operation is performed at
the fault output (E.PCH) only if
Pr. 65 = "0 or 4."
Limit by the measured amount
The fault (E.PCH) is output
when the measured amount
exceeds Pr. 763 Pre-charge upper

4.20.4 Second PID function (Pr.753 to Pr. 758, Pr.765 to Pr.769)
When the RT signal is ON and Pr. 753 Second PID action selection ≠ 9999, PID control is commanded by the
second function parameters.
When Pr. 753 = 9999, normal PID control is performed even if the second functions are valid.
When the control method is switched from the second PID control to the normal PID control, the integral value is
estimated. The integral value is estimated by calculating the integral term with the output frequency and the P
term. This method is same as when the control method changes to PID control when the frequency reaches the
automatic switchover frequency.

proportional band 100% 0.1 to 1000%
Set the proportional band for PID control, which is performed
while the RT signal is ON.
If the proportional band is narrow (parameter setting is small),
the manipulated variable varies greatly with a slight change of
the measured value. Hence, as the proportional band narrows,
the response sensitivity (gain) improves but the stability
deteriorates, e.g. hunting occurs.

Set the PID integral time for PID control, which is performed
while the RT signal is ON.
When deviation step is input, time (Ti) is the time required for
integral (I) action to provide the same manipulated variable as
proportional (P) action.
As the integral time decreases, the set point is reached earlier
but hunting occurs more easily.

⋅The control switches between PID control and second PID control by the following operation:
⋅ Turning ON/OFF the RT signal while Pr. 753 ≠ 9999
⋅ Setting "9999" or a value other than "9999" in Pr. 753 while the RT signal is ON.
⋅The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 125)
⋅In the initial setting, the RT signal is assigned to the RT terminal. By setting "3" to any of Pr. 178 to Pr. 189 (Input terminal function

Pr.579
Setting Name Description
0Basic system
The motor to be inverter-driven is always fixed and you can increase/decrease the number of
motors commercial power-driven by turning on and off the MC between the power supply and
motor with the output frequency.
1Alternative
system
As same as basic system (Pr. 579 = "0"), the motor to be driven by the inverter is fixed during
operation and you can control the number of motors operated by the commercial power with the
output frequency. When the inverter stops by the sleep function, the MC between the inverter and
motor is switched to switch motors to be inverter-driven.
2Direct system
When the start signal is entered, the motor is started by the inverter. When the conditions to start the
next motor are established, switching MCs between the inverter and motor and the power supply and
motor will change the inverter driven motor to commercial power-supply operation and start the next
motor by the inverter. Adversely, when conditions to stop the motor is established while multiple motors
are running, motors stop in order of first started motor (in the commercial power-supply operation).
3Alternative-
direct system
When the start signal is entered, the motor is started by the inverter. When the conditions to start
the next motor are established, switching MCs between the inverter and motor and the power
supply and motor will change the inverter driven motor to commercial power-supply operation and
start the next motor by the inverter. Conversely, when the conditions for stopping the motors are
enabled during running of several motors, the inverter-driven motor is decelerated to s stop and
the motors under commercial power supply operation are switched over to inverter-driven
operation after frequency search. Since frequency search is performed when the motor running
with commercial power-supply is switched to the inverter-driven operation, set a value other than
"9999" in Pr. 57 Restart coasting time. When Pr. 57 is set, the CS signal need not be turned ON.
REMARKS
· The starting order of motors to be driven returns to the initial status at an inverter reset. (Pr. 579 = "1, 2, 3")
·For Pr. 578 and Pr. 579, parameter write is disabled during operation. In addition, when the Pr. 578 or Pr. 579 setting has been
changed during stop, the starting order of motors also returns to the initial status.

)
⋅The inverter stops operation if the output frequency after PID control remains at less than the Pr. 576 Output
interruption detection level setting for longer than the time set in Pr. 575 Output interruption detection time. (At this
time, if "0 to 3" is set to Pr.554 PID signal operation selection, output is shut off (the inverter coasts to stop) when
SLEEP operation starts. If "10 to 13" is set, the inverter decelerates to a stop in the deceleration time set in Pr.8
when SLEEP operation starts.)
This function can reduce energy consumption in the low-efficiency, low-speed range.
⋅When the deviation (= set value - measured value) reaches the PID output shutoff cancel level (Pr. 577 setting -
1000%) while the PID output interruption function is ON, the PID output interruption function is canceled and
PID control operation is resumed automatically.
⋅While the PID output interruption function is ON, the PID output interruption signal (SLEEP) is output. At this
time, the inverter running signal (RUN) is OFF and the PID control operating signal (PID) is ON.
⋅For the terminal used for the SLEEP signal output, assign the function by setting "70" (positive logic) or "170"
(negative logic) in Pr. 190 to Pr. 196 (output terminal function selection).
* When the output rises to the output interruption cancel level during deceleration to a stop, output interruption gets cancelled, and the
inverter accelerates again to continue PID control. Pr.576 Output interruption detection level is invalid during deceleration.

· If the start signal is turned OFF during operation, the inverter-driven motor is decelerated to stop, and the motors under
commercial power supply operation are switched over to inverter-driven operation one at a time and decelerated to a stop
after frequency search in order from the longest operation time.
· When an error occurs while running, MC (RO1 to RO4) turns OFF and the inverter output is shut off.
· If the MRS signal is turned ON during operation, the inverter-driven motor is shut off. Although the motor with the longest

Special operation and frequency control
⋅When the motor is operated at 60Hz (or 50Hz), more efficient operation can be performed by the commercial power
supply than by the inverter. When the motor cannot be stopped for a long time for the maintenance/inspection of the
inverter, it is recommended to provide the commercial power supply circuit.
⋅To avoid commercial power supply being applied to the inverter output side when switching between inverter
operation and commercial power supply operation, provide an interlock which the MC of the commercial power
supply side turns ON only when the MC of the inverter output side is OFF. Using the electronic bypass sequence
function that outputs the timing signal for operation of the magnetic contactor, a complicated commercial power
supply switchover interlock can be provided by the inverter.

⋅The following shows the connection diagram of a typical electronic bypass sequence. Sink logic, Pr. 185 = "7", Pr.

CAUTION
⋅Connect the control power supply (R1/L11, S1/L21) in front of input side MC1. If the control power supply is connected behind
input side MC1, the electronic bypass sequence function is not executed.
⋅The electronic bypass sequence function is valid only when Pr. 135 = "1" in the external operation or combined operation mode
(PU speed command, external operation command Pr. 79 = "3"). When Pr. 135 = "1" in the operation mode other than the above,
MC1 and MC3 turn ON.
⋅When the MRS and CS signals are ON and the STF (STR) signal is OFF, MC3 is ON, but when the motor was coasted to a stop
from bypass operation last time, a start is made after the time set to Pr. 137 has elapsed.
⋅Inverter operation can be performed when the MRS, STF (STR) and CS signals turn ON. In any other case (MRS signal - ON),
bypass operation is performed.
⋅When the CS signal is turned OFF, the motor switches to bypass operation. However, when the STF (STR) signal is turned
OFF, the motor is decelerated to a stop in the inverter operation mode.
⋅When both MC2 and MC3 are OFF and either MC2 or MC3 is then turned ON, there is a waiting time set in Pr. 136.
⋅If electronic bypass sequence is valid (Pr. 135 = "1"), the Pr. 136 and Pr. 137 settings are ignored in the PU operation mode. The
input terminals (STF, CS, MRS, OH) of the inverter return to their normal functions.
⋅When the electronic bypass sequence function (Pr. 135 = "1") and PU operation interlock function (Pr. 79 = "7") are used
simultaneously, the MRS signal is shared by the PU operation external interlock signal unless the X12 signal is assigned.
(When the MRS and CS signals turn ON, inverter operation is enabled)
⋅Changing the terminal function using any of Pr. 178 to Pr. 189, 190 to Pr. 196 may affect the other functions. Please set
parameters after confirming the function of each terminal.

4.21.2 Regeneration avoidance function (Pr. 665, Pr. 882 to Pr. 886)
(1) What is regeneration avoidance function? (Pr. 882, Pr. 883)
⋅When the regeneration status is serious, the DC bus voltage rises and an overvoltage fault (E. OV) may occur.
When this bus voltage rise is detected and the bus voltage level reaches or exceeds Pr. 883, increasing the
frequency avoids the regeneration status.
⋅
The regeneration avoidance operation, you can select whether it is always activated or activated only a constant speed.
⋅Setting Pr. 882 to "1, 2" validates the regeneration avoidance function.
This function detects a regeneration status and increases the frequency to avoid the regeneration status.
Possible to avoid regeneration by automatically increasing the frequency and continue operation if the fan
happens to rotate faster than the set speed due to the effect of another fan in the same duct.

REMARKS
⋅The inclination of the frequency increased or decreased by the regeneration avoidance function changes depending on the
regeneration status.
⋅The DC bus voltage of the inverter is normally about times greater than the input voltage.
When the input voltage is 220VAC, the bus voltage is about 311VDC.
When the input voltage is 440VAC, the bus voltage is about 622VDC.
However, it varies with the input power waveform.
⋅The Pr. 883 setting should be kept higher than the DC bus voltage level. Otherwise, the regeneration avoidance function is
always ON even in the non-regeneration status and the frequency increases.
⋅While overvoltage stall ( ) is activated only during deceleration and stops the decrease in output frequency, the regeneration
avoidance function is always ON (Pr. 882 = 1) or activated only during a constant speed (Pr. 882 = 2) and increases the
frequency according to the regeneration amount.
⋅Note that when coping parameters to the inverter without this function (inverter assembled in and before September 2005),
copied Pr.882 ="2" is regarded as Pr.882 ="0"(regeneration avoidance function invalid).

PARAMETERS
(2) To detect the regeneration status during deceleration faster (Pr. 884)
⋅As the regeneration avoidance function cannot respond to an abrupt voltage change by detection of the bus
voltage level, the ratio of bus voltage change is detected to stop deceleration if the bus voltage is less than Pr. 883
Regeneration avoidance operation level.
Set that detectable bus voltage change ratio to Pr. 884 as detection sensitivity.
Increasing the setting raises the detection sensitivity
(4) Regeneration avoidance function adjustment (Pr. 665, Pr. 886)
⋅If the frequency becomes unstable during regeneration avoidance operation, decrease the setting of Pr. 886
Regeneration avoidance voltage gain. Reversely, if sudden regeneration causes an overvoltage fault, increase the
setting.
When vibration is not suppressed by decreasing the Pr. 886 setting, set a smaller value in Pr. 665 Regeneration
avoidance frequency gain.
CAUTION
Too small setting (low detection sensitivity) will disable detection, and too large setting will turn ON the regeneration avoidance
function if the bus voltage is varied by an input power change, etc.
(3) Limit regeneration avoidance operation frequency
(Pr. 885)
You can limit the output frequency compensated for (increased) by
the regeneration avoidance function.
⋅The frequency is limited to the output frequency (frequency prior to
regeneration avoidance operation) + Pr. 885 Regeneration avoidance
compensation frequency limit value during acceleration or constant
speed. If the frequency increased by regeneration avoidance
function exceeds the limit value during deceleration, the limit value
is held until the output frequency falls to 1/2 of Pr. 885.
⋅When the frequency increased by regeneration avoidance function
has reached Pr. 1 Maximum frequency, it is limited to the maximum
frequency.
⋅Pr. 885 is set to "9999", regeneration avoidance function operation
frequency setting is invalid.
CAUTION
⋅When regeneration avoidance operation is performed, (overvoltage stall) is displayed and the OL signal is output. Set
theoperation pattern at an OL signal output using Pr. 156 Stall prevention operation selection. Set the output timing of the OL
signalusing Pr. 157 OL signal output timer.
⋅When regeneration avoidance operation is performed, stall prevention is also activated.
⋅The regeneration avoidance function cannot shorten the actual deceleration time taken to stop the motor. The actual
deceleration time depends on the regenerative energy consumption capability. When shortening the deceleration time,
consider using the regeneration unit (FR-BU2, BU, FR-BU, MT-BU5, FR-CV, FR-HC, MT-HC) to consume regenerative energy
at constant speed.
⋅When using a regeneration unit (FR-BU2, BU, FR-BU, MT-BU5, FR-CV, FR-HC, MT-HC) to consume regenerative energy at
constant speed, set Pr. 882 = "0 (initial value)" (Regenerative avoidance function invalid). When using the regeneration unit, etc.
to consume regenerative energy at deceleration, set Pr. 882 = "2" (regeneration avoidance function valid only at a constant
speed).

⋅The deterioration degree of the main circuit capacitor is displayed in Pr. 258 as a life.
⋅On the assumption that the main circuit capacitor capacitance at factory shipment is 100%, the capacitor life is
displayed in Pr. 258 every time measurement is made. When the measured value falls to or below 85%, Pr. 255 bit 1
is turned ON and also an alarm is output to the Y90 signal.
⋅Measure the capacitor capacity according to the following procedure and check the deterioration level of the
capacitor capacity.
1) Check that the motor is connected and at a stop.
2) Set "1" (measuring start) in Pr. 259
3) Switch power OFF. The inverter applies DC voltage to the motor to measure the capacitor capacity while the
inverter is OFF.
4) After making sure that the power lamp is OFF, switch ON the power supply again.
5) Check that "3" (measuring completion) is set in Pr. 259, read Pr .258, and check the deterioration degree of the
main circuit capacitor.

Note that the output time range is 0.5 to 9s, and it is 0.5s when the output current
average value is less than 10% of the setting value of Pr. 557 and 9s when exceeds
180%.
Example)When Pr. 557 = 10A and the average value of output current is 15A
As 15A/10A × 5s = 7.5, the current average value monitor signal is output
as low pulse shape for 7.5s.
After the output current average value is output as low pulse shape, the
maintenance timer value is output as high pulse shape. The output time of the
maintenance timer value is obtained from the following calculation.
Note that the output time range is 2 to 9s, and it is 2s when Pr. 503 is less than
16000h and 9s when exceeds 72000h.
REMARKS
⋅Mask of data output and sampling of output current are not performed during acceleration/deceleration.
⋅When the speed is changed to acceleration/deceleration
from constant speed during start bit output, the data is
judged as invalid, the start bit is output as high pulse
shape for 3.5s, and the end signal is output as low pulse
shape for 16.5s.
The signal is output for at least 1 cycle even when
acceleration/deceleration state continues after the start bit
output is completed.
⋅When the output current value (inverter output current monitor) is 0A on completion of the 1 cycle signal output, the signal is not

Reset method of protective function
When a fault occurs in the inverter, the inverter trips and the PU display automatically changes to one of the following
fault or alarm indications.
If the fault does not correspond to any of the following faults or if you have any other problem, please contact your sales
representative or distributor.
•Retention of fault output signal ................ When the magnetic contactor (MC) provided on the input side of the
inverter is opened when a fault occurs, the inverter's control power will be
lost and the fault output will not be held.
•Fault or alarm indication .......................... When a fault or alarm occurs, the operation panel display automatically
switches to the fault or alarm indication
•Resetting method..................................... When a fault occurs, the inverter output is kept stopped. Unless reset,
therefore, the inverter cannot restart. (Refer to page 332.)
•When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation.
Not doing so may lead to the inverter fault and damage.
Inverter fault or alarm indications are roughly categorized as below.
(1) Error message
A message regarding operational fault and setting fault by the operation panel (FR-DU07) and parameter unit (FR-
PU04 /FR-PU07) is displayed. The inverter does not trip.
(2) Warnings
The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will
lead to a fault.
(3) Alarm
The inverter does not trip. You can also output an alarm signal by making parameter setting.
(4) Fault
When a fault occurs, the inverter trips and a fault signal is output.
5.1 Reset method of protective function
The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value
of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
Inverter recovers about 1s after the reset is released.
REMARKS
• For the details of fault displays and other troubles, also refer to page 333.
• Past eight faults can be displayed using the setting dial. (Refer to page 59 for the operation.)
Operation 1: ..... Using the operation panel, press to reset the inverter.
(This may only be performed when a fault occurs. (Refer to page 338 for
fault.))
Operation 2: ...... Switch OFF the power once. After the indicator of the operation panel
turns OFF, switch it ON again.
Operation 3: . .... Turn ON the reset signal (RES) for more than 0.1s. (If the RES signal is
kept ON, "Err." appears (flickers) to indicate that the inverter is in a
reset status.)

REMARKS
• When a fault occurs during PLC function, turning ON of X51 signal can release fault without interrupting PLC function. (Refer to
the FR-F700 PLC function programming manual. )
CAUTION
⋅OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter fault with the start signal
ON restarts the motor suddenly.

The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent
any fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust,
dirt and vibration, changes in the parts with time, service life, and other factors.
• Precautions for maintenance and inspection
For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor. When
accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched OFF, and
then make sure that the voltage across the main circuit terminals P/+ and N/− of the inverter is not more than 30VDC
using a tester, etc.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION
6.1.7 Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced
performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.
Use the life check function as a guidance of parts replacement.
*1 Replacement years for when the yearly average surrounding air temperature is 40°C (104°F)
(without corrosive gas, flammable gas, oil mist, dust and dirt etc)
*2 Output current : 80% of the inverter rated current
(1) Cooling fan
The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit
semiconductor is greatly affected by the surrounding air temperature. When unusual noise and/or vibration is noticed
during inspection, the cooling fan must be replaced immediately.

(2) Replacement procedure of the cooling fan when using a heatsink protrusion attachment
(FR-A7CN)
(3) Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum
electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated
by the adverse effects of ripple currents, etc.
The replacement intervals greatly vary with the surrounding air temperature and operating conditions. When the
inverter is operated in air-conditioned, normal environment conditions, replace the capacitors about every 10 years.
The appearance criteria for inspection are as follows:
1) Case: Check the side and bottom faces for expansion
2) Sealing plate: Check for remarkable warp and extreme crack.
3) Check for external crack, discoloration, fluid leakage, etc. Judge that the capacitor has reached its life when the
measured capacitance of the capacitor reduced below 80% of the rating.
Refer to page 359 to perform the life check of the main circuit capacitor.
(4) Relays
To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times
(switching life).
6.1.8 Inverter replacement
The inverter can be replaced with the control circuit wiring kept connected. Before replacement, remove the wiring
cover of the inverter.
1) Loosen the two installation screws in both ends of the control circuit terminal block. (These screws cannot be removed.)
Pull down the terminal block from behind the control circuit terminals.
2) Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block
and fix it with the mounting screws.
When replacing a cooling fan, remove a top cover of the
heatsink protrusion attachment and perform replacement.
After replacing the cooling fan, replace the top cover in the
original position.
CAUTION
Before starting inverter replacement, switch power OFF, wait for at least 10 minutes, and then check the voltage with a tester
and such to ensure safety.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION
6.2 Measurement of main circuit voltages, currents and powers
6.2.1 Measurement of voltages and currents
Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement
data depends on the instruments used and circuits measured.
When instruments for commercial frequency are used for measurement, measure the following circuits with the
instruments given on the next page.
When installing meters etc. on the inverter output side
When the inverter-to-motor wiring length is large, especially in the 400V class, small-capacity models, the meters
and CTs may generate heat due to line-to-line leakage current. Therefore, choose the equipment which has
enough allowance for the current rating.
When measuring and indicating the output voltage and output current of the inverter, it is recommended to utilize
the AM and CA terminal output function of the inverter.

Measuring Points and Instruments
*1 Use an FFT to measure the output voltage accurately. A tester or general measuring instrument cannot measure accurately.
*2 When the carrier frequency exceeds 5kHz, do not use this instrument since using it may increase eddy-current losses produced in metal parts
inside the instrument, leading to burnout. If the wiring length between the inverter and motor is long, the instrument and CT may generate
heat due to line-to-line leakage current.
*3 When the setting of Pr. 195 ABC1 terminal function selection is positive logic
*4 A digital power meter (designed for inverter) can also be used to measure.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION
Measurement of main circuit voltages,
currents and powers
6.2.2 Measurement of powers
Use digital power meters (for inverter) for the both of inverter input and output side. Alternatively, measure using
electrodynamic type single-phase wattmeters for the both of inverter input and output side in two-wattmeter or three-
wattmeter method. As the current is liable to be imbalanced especially in the input side, it is recommended to use the
three-wattmeter method.
Examples of measured value differences produced by different measuring meters are shown below.
An error will be produced by difference between measuring instruments, e.g. power calculation type and two- or three-
wattmeter type three-phase wattmeter. When a CT is used in the current measuring side or when the meter contains a
PT on the voltage measurement side, an error will also be produced due to the frequency characteristics of the CT and
PT.
6.2.3 Measurement of voltages and use of PT
(1) Inverter input side
As the input side voltage has a sine wave and it is extremely small in distortion, accurate measurement can be made
with an ordinary AC meter.
(2) Inverter output side
Since the output side voltage has a PWM-controlled rectangular wave, always use a rectifier type voltmeter. A needle
type tester cannot be used to measure the output side voltage as it indicates a value much greater than the actual
value. A moving-iron type meter indicates an effective value which includes harmonics and therefore the value is larger
than that of the fundamental wave. The value monitored on the operation panel is the inverter controlled voltage itself.
Hence, that value is accurate and it is recommended to monitor values (provide analog output) using the operation
panel.
(3) PT
No PT can be used in the output side of the inverter. Use a direct-reading meter. (A PT can be used in the input side of
the inverter.)

Measurement of main circuit voltages,

6.2.4 Measurement of currents
Use moving-iron type meters on both the input and output sides of the inverter. However, if the carrier frequency
exceeds 5kHz, do not use that meter since an overcurrent losses produced in the internal metal parts of the meter will
increase and the meter may burn out. In this case, use an approximate-effective value type.
As the inverter input side current is easily imbalanced, measurement of currents in all three phases is recommended.
Correct values cannot be measured in one or two phases. On the other hand, the phase imbalanced ratio of the output
side current must be within 10%.
When a clamp ammeter is used, always use an effective value detection type. A mean value detection type produces a
large error and may indicate an extremely smaller value than the actual value. The value monitored on the operation
panel is accurate if the output frequency varies, and it is recommended to monitor values (provide analog output) using
the operation panel.
An example of the measured value difference produced by different measuring meters is shown below.
6.2.5 Use of CT and transducer
A CT may be used in both the input and output sides of the inverter, but the one used should have the largest possible
VA ability because an error will increase if the frequency gets lower.
When using a transducer, use the effective value calculation type which is immune to harmonics.
6.2.6 Measurement of inverter input power factor
Use the effective power and apparent power to calculate the inverter input power factor. A power-factor meter cannot
indicate an exact value.
[Measurement conditions]
Value indicated by moving-iron type ammeter is 100%.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION
Measurement of main circuit voltages,
currents and powers
6.2.7 Measurement of converter output voltage (across terminals P/+ and N/-)
The output voltage of the converter is developed across terminals P/+ and N/- and can be measured with a moving-
coil type meter (tester). Although the voltage varies according to the power supply voltage, approximately 270V to 300V
(approximately 540V to 600V for the 400V class) is output when no load is connected and voltage decreases when a
load is connected.
When regenerative energy is returned from the motor during deceleration, for example, the converter output voltage
rises to nearly 400V to 450V (800V to 900V for the 400V class) maximum.
6.2.8 Insulation resistance test using megger
For the inverter, conduct the insulation resistance test on the main circuit only as shown below and do not perform the
test on the control circuit. (Use a 500VDC megger.)
6.2.9 Pressure test
Do not conduct a pressure test. Deterioration may occur.
CAUTION
• Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals of the
inverter so that the test voltage is not applied to the inverter.
• For the electric continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or
buzzer.

*1 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
*2 The rated output capacity indicated assumes that the output voltage is 220V.
*3 When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency automatically decreases if the inverter
output current exceeds the value in parenthesis of the rated current. This may cause the motor noise to increase.
*4 The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated
duty, allow time for the inverter and motor to return to or below the temperatures under 100% load.
*5 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting
range. However, the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.
*6 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and
cables).
*7 When the hook of the inverter front cover is cut off for installation of the plug-in option, the inverter changes to an open type (the structure is

*1 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
*2 The rated output capacity indicated assumes that the output voltage is 440V.
*3 When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency automatically decreases if the inverter
output current exceeds the value in parenthesis of the rated current. This may cause the motor noise to increase.
*4 The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated
duty, allow time for the inverter and motor to return to or below the temperatures under 100% load.
*5 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting
range. However, the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.
*6 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
*7 When the hook of the inverter front cover is cut off for installation of the plug-in option, protective structure of the inverter changes to an open
type (the structure is no longer NEMA1).
*8 FR-DU07: IP40 (except for the PU connector)

Heatsink protrusion attachment procedure
7.4 Heatsink protrusion attachment procedure
When encasing the inverter in an enclosure, the generated heat amount in an enclosure can be greatly reduced by
installing the heatsink portion of the inverter outside the enclosure. When installing the inverter in a compact
enclosure, etc., this installation method is recommended.
7.4.1 When using a heatsink protrusion attachment (FR-A7CN)
For the FR-F720-00105 to 04750, FR-F740-00023 to 03610, a heatsink can be protruded outside the enclosure
using a heatsink protrusion attachment (FR-A7CN). (Attachment is not required when protruding the heatsink for
FR-F740-04320 or larger inverter.) For a panel cut dimension drawing and an installation procedure of the heatsink
protrusion attachment (FR-A7CN) to the inverter, refer to a manual of "heatsink protrusion attachment (FR-A7CN01
to 11)".
7.4.2 Protrusion of heatsink of the FR-F740-04320 or more
(1) Panel cutting
Cut the panel of the enclosure according to the inverter capacity.
