2) Grounding capacitor disconnecting switch and taps
Warning
Mandatory
The grounding capacitor disconnecting tap is provided with a protection cover. To avoid shock hazards,
always attach the cover after connecting or disconnecting the capacitor to or from the tap.
Every three-phase 400V model has a built-in high-attenuation noise filter, which is grounded through a
capacitor.
If you want to disconnect the capacitor from the grounding line to reduce the amount of leakage current,
you can do so easily using the switch or tap. Keep in mind, however, that disconnecting the capacitor
from the grounding line causes the inverter to become non-compliant with the EMC directive. Also note
that the inverter must always be turned off before the capacitor is disconnected or reconnected.
Note: In case of three phase 400V-5.5kW or less model, if you disconnect the capacitor from ground,
set the parameter of carrier frequency H to 6kHz with motor cable length 30m or less.

1.4 Notes on the application
1.4.1 Motors
When the VF-FS1 and the motor are used in conjunction, pay attention to the following items.
Warning
Mandatory
Use an inverter that conforms to the specifications of power supply and three-phase induction motor
being used. If the inverter being used does not conform to those specifications, not only will the three-
phase induction motor not rotate correctly, but it may cause serious accidents through overheating and
fire.
Comparisons with commercial power operation.
The VF-FS1 Inverter employs the sinusoidal PWM system. However, the output voltage and output
current are not perfect sine waves, they have a distorted wave that is close to sinusoidal waveform.
This is why compared to operation with a commercial power there will be a slight increase in motor
temperature, noise and vibration.
Operation in the low-speed area
When running continuously at low speed in conjunction with a general purpose motor, there may be a
decline in that motor's cooling effect. If this happens, operate with the output decreased from rated load.
To carry out low-speed operation continuously at the rated torque, we recommend to use a inverter
rated motor or a forced cooled motor designed for use with an inverter. When operating in conjunction
with a inverter rated motor, you must change the inverter's motor overload protection level to VF motor
use (QNO).
Adjusting the overload protection level
The VF-FS1 Inverter protects against overloads with its overload detection circuits (electronic thermal).
The electronic thermal's reference current is set to the inverter's rated current, so it must be adjusted in
line with the rated current of the general purpose motor being used in combination.
High speed operation at and above 60Hz
Operating at frequencies greater than 60Hz will increase noise and vibration. There is also a possibility
this will exceed the motor's mechanical strength limits and the bearing limits so you should inquire to
the motor's manufacturer about such operation.
Method of lubricating load mechanisms
Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the
lubricating effect. Check with the manufacturer of the reduction gear to find out about operable gearing
area.
E6581381
A-14

Low loads and low inertia loads
The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of
50 % or under of the load percentage, or when the load's inertia moment is extremely small. If that
happens reduce the carrier frequency.
Occurrence of instability
Unstable phenomena may occur with the load and motor combinations shown below.
⋅Combined with a motor that exceeds applicable motor ratings recommended for the inverter
⋅Combined with special motors
To deal with the above lower the settings of inverter carrier frequency.
⋅Combined with couplings between load devices and motors with high backlash
When using the inverter in the above combination, use the S-pattern acceleration/deceleration function,
or when vector control is selected, adjust the speed control response/stability factor or switch to V/F
control mode.
⋅Combined with loads that have sharp fluctuations in rotation such as piston movements
In this case, please do not use this inverter.
Braking a motor when cutting off power supply
A motor with its power cut off goes into free-run, and does not stop immediately. To stop the motor
quickly as soon as the power is cut off install an auxiliary brake. There are different kinds of brake
devices, both electrical and mechanical. Select the brake that is best for the system.
Load that produces regenerative torque
Do not use the inverter in combination with a load, such as an air conditioner, that produces
regenerative torque. Or the overvoltage or overcurrent protection circuit of the inverter may be activated,
causing the inverter to trip. If overvoltage tripping occurs during deceleration, lengthen the deceleration
time.
E6581381
A-15
1
Braking motor
When using a braking motor, if the braking circuit is directly connected to the inverters's output
terminals, the brake cannot be released because of the lowered starting voltage. Therefore, when
using a braking motor, connect the braking circuit to the inverter's power supply side, as shown in the
figure below. Usually, braking motors produce larger noise in low speed ranges.
Note: In the case of the circuit shown on the below, assign the function of detecting low-speed signals
to the RY and RC terminals. Make sure the parameter H is set to (factory default
setting).
Measures to protect motors against surge voltages
In a system in which a 400V-class inverter is used to control the operation of a motor, very high surge
voltages may be produced. When applied to the motor coils repeatedly for a long time, may cause
deterioration of their insulation, depending on the cable length, cable routing and types of cables used.
Here are some examples of measures against surge voltages.
(1) Lower the inverter’s carrier frequency.
(2) Set the parameter H (Carrier frequency control mode selection) to or .
(3) Use a motor with high insulation strength.
(4) Insert an AC reactor or a surge voltage suppression filter between the inverter and the motor.
1.4.2 Inverters
Protecting inverters from overcurrent
The inverter has an overcurrent protection function. The programmed current level is set to the
inverter's maximum applicable motor. If the motor used has a small capacity, the overcurrent level and
the electronic thermal protection must be readjusted. If adjustment is necessary, see 5.12, and make
adjustments as directed.
Inverter capacity
Do not use a small-capacity (kVA) inverter to control the operation of a large-capacity motor (two-class
or more larger motor), no matter how light the load is. Current ripple will raise the output peak current
making it easier to set off the overcurrent trip.
E6581381

Power factor correction capacitor
Power factor correction capacitors cannot be installed on the output side of the inverter. When a motor
is run that has a power factor correction capacitor attached to it, remove the capacitors. This can cause
inverter malfunction trips and capacitor destruction.

Operating at other than rated voltage
Connections to voltages other than the rated voltage described in the rating label cannot be made. If a
connection must be made to a power supply other than one with rated voltage, use a transformer to
raise or lower the voltage to the rated voltage.

Breaking of selected inverter
There is no fuse in the inverter's main circuit. Thus, as the diagram above shows, when more than one
inverter is used on the same power line, you must select interrupting characteristics so that only the
MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1). When you
cannot select the proper characteristics install a circuit interrupting fuse between the MCCB2 and the
INV1.
If power supply distortion is not negligible
If the power supply distortion is not negligible because the inverter shares a power distribution line with
other systems causing distorted waves, such as systems with thyristors or large-capacity inverters,
install an input reactor to improve the input power factor, to reduce higher harmonics, or to suppress
external surges.

■Disposal
If an inverter is no longer usable, dispose of it as industrial waste.
1.4.3 What to do about the leak current
Warning
Current may leak through the inverter's input/output wires because of insufficient electrostatic capacity on the motor with
bad effects on peripheral equipment.
The leakage current’s value is affected by the carrier frequency and the length of the input/output wires. Test and adopt
the following remedies against leak current.
(1) Effects of leak current across ground
Leakage current may flow not just through the inverter system but also through ground wires to other
systems. Leakage current will cause earth leakage breakers, leakage current relays, ground relays, fire
alarms and sensors to operate improperly, and it will cause superimposed noise on the CRT screen or
display of incorrect current detection with the CT.

Remedies:
1.If there is no radio-frequency interference or similar problem, detach the built-in noise filter
capacitor, using the grounding capacitor disconnecting switch or tap. ⇒ See section 1.3.2-2.
2.Reduce PWM carrier frequency.
The setting of PWM carrier frequency is done with the parameter H.
Although the electromagnetic noise level is reduced, the motor acoustic noise is increased.
3. Use high frequency remedial products for earth leakage breakers.

Leakage current path across wires
(1) Thermal relays
The high frequency component of current leaking into electrostatic capacity between inverter out-
put wires will increase the effective current values and make externally connected thermal relays
operate improperly. If the wires are more than 50 meters long, it will be easy for the external
thermal relay to operate improperly with models having motors of low rated current (several
A(ampere) or less), especially the 400V class low capacity (5.5kW or less) models, because the
leak current will increase in proportion to the motor rating.
Remedies:
1.Use the electronic thermal built into the inverter. ⇒ See section 5.12.
The setting of the electronic thermal is done using parameter QNO, VJT.
2.Reduce the inverter's PWM carrier frequency. However, that will increase the motor's magnetic
noise.
The setting of PWM carrier frequency is done with the parameter H. ⇒ See section 6.11.
3.This can be improved by installing 0.1µ~0.5µF - 1000V film capacitor to the input/output terminals of
each phase in the thermal relay.

(2) CT and ammeter
If a CT and ammeter are connected externally to detect inverter output current, the leak current's high
frequency component may destroy the ammeter. If the wires are more than 50 meters long, it will be
easy for the high frequency component to pass through the externally connected CT and be
superimposed on and burn the ammeter with models having motors of low rated current (several
A(ampere) or less), especially the 400V class low capacity (5.5kW or less) models, because the leak
current will increase in proportion to the motor's rated current.
Remedies:
1.Use a meter output terminal in the inverter control circuit.
The load current can be output on the meter output terminal (FM). If the meter is connected, use an
ammeter of 1mAdc full scale or a voltmeter of 7.5V-1mA full scale.
0-20mAdc (4-20mAdc) can be also output. ⇒ See section 5.4.
2.Use the monitor functions built into the inverter.
Use the monitor functions on the panel built into the inverter to check current values.
⇒See section 8.1.1.

■How to install
Danger
Prohibited
•Do not install or operate the inverter if it is damaged or any component is missing.
This can result in electric shock or fire. Please consult your local sales agency for repairs. Call your
local sales agency for repairs.
Mandatory
•Mount the inverter on a metal plate.
The rear panel gets very hot. Do not install in an inflammable object, this can result in fire.
•Do not operate with the front panel cover removed.
This can result in electric shock.
•An emergency stop device must be installed that fits with system specifications (e.g. shut off input
power then engage mechanical brake).
Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury.
•All options used must be those specified by Toshiba.
The use of any other option may result in an accident.
Warning
Mandatory
•The main unit must be installed on a base that can bear the unit's weight.
If the unit is installed on a base that cannot withstand that weight, the unit may fall resulting in injury.
•If braking is necessary (to hold motor shaft), install a mechanical brake.
The brake on the inverter will not function as a mechanical hold, and if used for that purpose, injury
may result.
Install the inverter in a well-ventilated indoor place and mount it on a flat metal plate in portrait orientation.
If you are installing more than one inverter, the separation between inverters should be at least 5 centimeters,
and they should be arranged in horizontal rows. If the inverters are horizontally arranged with no space
between them (side-by-side installation), peel off the ventilation seals on top of the inverter. It is necessary to
decrease the current if the inverter is operated at over 40°C.

■Calorific values of the inverter and the required ventilation
About 5% of the rated power of the inverter will be lost as a result of conversion from AC to DC or from DC to
AC. In order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the
interior of the cabinet must be ventilated and cooled.
The amount of forcible air-cooling ventilation required and the necessary heat discharge surface quantity
when operating in a sealed cabinet according to motor capacity are as follows.
Note1: The heat loss for the optional external devices (input reactor, radio noise reduction filters, etc.) is not
included in the calorific values in the table

■Panel designing taking into consideration the effects of noise
The inverter generates high frequency noise. When designing the control panel setup, consideration must be
given to that noise. Examples of measures are given below.
•Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the
same conduit, do not run them parallel, and do not bundle them.
•Provide shielding and twisted wire for control circuit wiring.
•Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same
conduit, do not run them parallel, and do not bundle them.
•Ground the inverter ground terminals ( ).

■Installing more than one unit in a cabinet
If you are installing two or more inverters in one cabinet, pay attention to the following.
•Inverters may be installed side by side with each other with no space left between them.
•When installing inverters side by side, detach the caution label on the top surface of each inverter and
use them where the ambient temperature will not rise above 40°C.
When using inverters where the ambient temperature will rise above 40°C, leave a space of 5 cm or
more between them and remove the caution label from the top of each inverter, and operate each
inverter at a current lower than the rated one.
•Ensure a space of at least 20 centimeters on the top and bottom of the inverters.
•Install an air deflecting plate so that the heat rising up from the inverter on the bottom does not affect the
inverter on the top.

Connection of input power by someone who does not have that expert knowledge may result in fire or
electric shock.
•Connect output terminals (motor side) correctly.
If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury.
•Wiring must be done after installation.
If wiring is done prior to installation that may result in injury or electric shock.
•The following steps must be performed before wiring.
(1) Shut off all input power.
(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage (800VDC or more), and check to make sure that the
voltage to the DC main circuits (across PA/+ and PC/-) is 45V or less.
If these steps are not properly performed, the wiring will cause electric shock.
•Tighten the screws on the terminal board to specified torque.
If the screws are not tightened to the specified torque, it may lead to fire.

Danger
Be Grounded
•Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or
current leak occurs.
Warning
Prohibited
•Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output
(motor side) terminal.
This could cause a fire.
■Preventing radio noise
To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's power
terminals (R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).
■Control and main power supply
The control power supply and the main circuit power supply for the VF-FS1 are the same.
⇒ See section 6.17.3.
If a malfunction or trip causes the main circuit to be shut off, control power will also be shut off. When
checking the cause of the malfunction or the trip, use the trip holding retention selection parameter.
■Wiring
•Because the space between the main circuit terminals is small use sleeved pressure terminals for the
connections. Connect the terminals so that adjacent terminals do not touch each other.
•For ground terminal use wires of the size that is equivalent to or larger than those given in table 10.1
and always ground the inverter (200V voltage class: D type ground, 400V class: C type ground).
Use as large and short a ground wire as possible and wire it as close as possible to the inverter.
•For the sizes of electric wires used in the main circuit, see the table in 10.1.
•The length of the main circuit wire in 10.1 should be no longer than 30 meters. If the wire is longer than
30 meters, the wire size (diameter) must be increased.
2.2 Standard connections
Danger
Prohibited
•Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3).
Connecting input power to the output could destroy the inverter or cause a fire.
•Do not insert a resistor between DC terminals (between PA/+ and PC/-).
It could cause a fire.
•First shut off input power and wait at least 10 minutes before touching wires on equipment (MCCB) that
is connected to inverter power side.
Touching the wires before that time could result in electric shock.

■SINK (Negative) logic/SOURCE (Positive) logic (When the
inverter's internal power supply is used)
Current flowing out turns control input terminals on. These are called sink logic terminals.
The general used method in Europe is source logic in which current flowing into the input terminal turns it
on.
Sink logic is sometimes referred to as negative logic, and source logic is referred to as positive logic.
Each logic is supplied with electricity from either the inverter's internal power supply or an external power
supply, and its connections vary depending on the power supply used.

■Selecting the functions of the VIA terminals between analog input and contact
input
The functions of the VIA terminal can be selected between analog input and contact input by changing
parameter settings (H). (Factory default setting: Analog input)
When using these terminals as contact input terminals in a sink logic circuit, be sure to insert a resistor
between the P24 and VIA terminals. (Recommended resistance: 4.7KΩ-1/2W)
When using the VIA terminal as a contact input terminal, be sure to turn the VIA (SW3) switch to the V
position. If no resistor is inserted or the VIA (SW3) slide switch is not turned to the V position, contact input
will be left always ON, which is very dangerous.
Switch between analog input and contact input before connecting the terminals to the control circuit
terminals. Otherwise the inverter or devices connected to it may be damaged.
E6581381

+The figure on the right shows an example of the
connection of input terminals VIA when there is used
as contact input terminals. This example illustrates
the connection when the inverter is used in sink
(Negative) logic mode.
■Logic switching/Voltage-current output switching (slide switch)
(1) Logic switching
Use SW4 to switch between logics.
Switch between logics before wiring to the inverter and without supplying power. If switching between
sink, source and PLC is done when power is turned on after switching or when the inverter is supplied
with power, the inverter might become damaged. Confirm it before supplying power.
(2) Voltage-current output switching
Use the FM (SW2) switch to switch between voltage output and current output.
Switch the FM terminal's voltage-current output before wiring to inverter or without supplying power.

3. Operations
Danger
Prohibited
•Do not touch inverter terminals when electrical power is going to the inverter even if the motor is
stopped.
Touching the inverter terminals while power is connected to it may result in electric shock.
•Do not touch switches when the hands are wet and do not try to clean the inverter with a damp cloth.
Such practices may result in electric shock.
•Do not go near the motor in alarm-stop status when the retry function is selected.
The motor may suddenly restart and that could result in injury.
Take measures for safety, e.g. attaching a cover to the motor, against accidents when the motor
unexpectedly restarts.
Mandatory
•Turn power on only after attaching the front cover or closing door if enclosed in a cabinet.
If power is turned on without the front cover attached or closing door if enclosed in a cabinet, that may
result in electric shock or other injury.
•If the inverter begins to emit smoke or an unusual odor, or unusual sounds, immediately turn power off.
If the equipment is continued in operation in such a state, the result may be fire. Call your local sales
agency for repairs.
•Always turn power off if the inverter is not used for long periods of time.
•Turn input power on after attaching the front cover.
When enclosed inside a cabinet and using with the front cover removed, always close the cabinet
doors first and then turn power on. If the power is turned on with the front cover or the cabinet doors
open, it may result in electric shock.
•Make sure that operation signals are off before resetting the inverter after malfunction.
If the inverter is reset before turning off the operating signal, the motor may restart suddenly causing
injury.

4. Basic VF-FS1 operations
The VF-FS1 has the following three monitor modes.
Standard monitor mode : The standard inverter mode. This mode is enabled when
inverter power goes on.
This mode is for monitoring the output frequency and setting the frequency
designated value. In it is also displayed information about status alarms during
running and trips.
•Setting frequency designated values ⇒ See section 3.1.2
•Status alarm
If there is an error in the inverter, the alarm signal and the frequency will flash
alternately in the LED display.
E: When a current flows at or higher than the overcurrent stall level.
R: When a voltage is generated at or higher than the over voltage stall
level.
N: When a load reaches 50% or higher of the overload trip value.
J: When the temperature reaches the overheating protection alarm level.
Setting monitor mode : The mode for setting inverter parameters.
How to set parameters ⇒ See section 4.2.
Status monitor mode : The mode for monitoring all inverter status.
Allows monitoring of set frequencies, output current/voltage and terminal
information.
For more on how to use the monitor ⇒ See section 8.1.

4.2 How to set parameters
The standard default parameters are programmed before the unit is shipped from the factory. Parameters can be
divided into 5 major categories. Select the parameter to be changed or to be searched and retrieved.
Basic parameters : The basic parameters that must be programmed
before the first use. ⇒ See section 4.2.1.
Extended parameters : The parameters for detailed and special setting.
⇒ See section 4.2.2.
User parameters
(automatic edit function)
: Indicates parameters that are different from the
standard default setting parameters. Use them to
check after setting and to change setting.
(Parameter title: I4W). ⇒ See section 4.2.3.
: The wizard function refers to the special function of
calling up ten frequently used parameters.
You can set up the inverter easily by simply setting the
parameters in one after another. (Parameter name:
CWH). ⇒ See section 4.2.4.
: This parameter has the function of displaying, in
reverse chronological order, the five parameters that
were changed last. This function comes in very handy
when you adjust the inverter repeatedly using the
same parameter. (Parameter name: CWJ).
⇒ See section 4.2.5.
* Adjustment range of parameters
JK: An attempt has been made to assign a value that is higher than the programmable range. Or, as
a result of changing other parameters, the programmed value of the parameter that is now
selected exceeds the upper limit.
NQ: An attempt has been made to assign a value that is lower than the programmable range. Or, as a
result of changing other parameters, the programmed value of the parameter that is now selected
exceeds the lower limit.
If the above alarm is flashing on and off, no setting can be done of values that are equal to or greater
than JK or equal to or lower than NQ.

5. Basic parameters
Before you operate the inverter, the parameters that you must first program are the basic parameters.
5.1 Setting acceleration/deceleration time
CW ：Automatic acceleration/deceleration
CEE ：Acceleration time 1
FGE ：Deceleration time 1
•Function
1) For acceleration time 1 CEE programs the time that it takes for the inverter output frequency to go from
0Hz to maximum frequency HJ.
2) For deceleration time 1 FGE programs the time that it takes for the inverter output frequency to got
from maximum frequency HJ to 0Hz.
5.1.1 Automatic acceleration/deceleration
This automatically adjusts acceleration and deceleration time in line with load size.
CW =
* Adjusts the acceleration/deceleration time automatically within the range of 1/8 to 8 times as long as the
time set with the CEE or FGE, depending on the current rating of the inverter.
CW =
* Automatically adjusts speed during acceleration only. During deceleration, speed is not adjusted
automatically but reduced at the rate set with FGE.

+When automatically setting acceleration/deceleration time, always change the acceleration/deceleration
time so that it conforms to the load. The acceleration/deceleration time changes constantly with load
fluctuations. For inverters that requires a fixed acceleration/deceleration time, use the manual settings
(CEE, FGE).
+Setting acceleration/deceleration time (CEE,FGE) in conformance with mean load allows optimum
setting that conforms to further changes in load.
+Use this parameter after actually connecting the motor.
+When the inverter is used with a load that fluctuates considerably, it may fail to adjust the acceleration or
deceleration time in time, and therefore may be tripped.

Note: When the acceleration/deceleration time is set at 0.0 seconds, the inverter speed increases or reduces
speed within 0.05 seconds.
+If the programmed value is shorter than the optimum acceleration/deceleration time determined by load
conditions, overcurrent stall or overvoltage stall function may make the acceleration/deceleration time
longer than the programmed time. If an even shorter acceleration/deceleration time is programmed, there
may be an overcurrent trip or overvoltage trip for inverter protection.

■Adjusting the meter in inverter stop state
•Adjustment of output current (HOUN=)
If, when adjusting the meter for output current, there are large fluctuations in data during adjustment,
making adjustment difficult, the meter can be adjusted in inverter stop state.
When setting HOUN to  for fixed output 1 (100% output current), a signal of absolute values will be
output (inverter's rated current = 100%). In this state, adjust the meter with the HO (Meter adjustment)
parameter.
Similarly, if you set HOUN to  for fixed output 2 (output current at 50%), a signal that is sent out when
half the inverter's rated current is flowing will be output through the FM terminal.
After meter adjustment is ended, set HOUN to (output current).
•Adjustment of other items (HOUN=, to , )
If parameter HOUN is set to : Fixed output 3 (Other than the output current: 100%), a signal that is
sent out when HOUN is set to , to , (100%) will be output through the FM terminal.
100% standard value for each item is the following:
HOUN=, ,  : Maximum frequency (HJ)
HOUN=, : 1.5 times of rated voltage
HOUN=, : 1.85 times of rated power

+Motor constant must be set
If the motor you are using is a 4P Toshiba standard motor and if it has the same capacity as the inverter,
there is basically no need to set the motor constant. In any other case, be sure to set the parameters H
to H properly.
Be sure to set H (rated current of motor) and H (rated speed of motor) correctly, as specified on
the motor’s nameplate. For the setting of H (no-load current of motor), refer to the motor test report.
There are two procedures for setting the other motor constants.
1) The motor constant can be automatically set (auto-tuning). Set the extended parameter H to .
⇒ For details, see selection 1 in 6.15.1.
2) Each motor constant can be set individually. ⇒ For details, see selection 2 in 6.15.1.

6) Operating a permanent magnet motor
Setting of V/F control mode selection RV to (PM motor control)
Permanent magnet motors (PM motors) that are light, small in size and highly efficient, as compared to
induction motors, can be operated in sensor-less operation mode.
Note that this feature can be used only for specific motors. For more information, contact your Toshiba dealer.
7) Precautions on vector control
1) When exercising vector control, be sure to set the extended parameters H to H properly. Be
sure to set H (rated current of motor) and H (rated speed of motor) correctly, as specified on
the motor’s nameplate. For the setting of H (no-load current of motor), refer to the motor test report.
2) The sensorless vector control exerts its characteristics effectively in frequency areas below the base
frequency (XN). The same characteristics will not be obtained in areas above the base frequency.
3) Set the base frequency to anywhere from 40 to 120Hz during vector control (RV=).
4) Use a general purpose squirrel-cage motor with a capacity that is the same as the inverter's rated capacity or
one rank below.
The minimum applicable motor capacity is 0.1kW.
E6581381
E-22
5
5) Use a motor that has 2-8 P.
6) Always operate the motor in single operation (one inverter to one motor). Sensorless vector control
cannot be used when one inverter is operated with more than one motor.
7) The maximum length of wires between the inverter and motor is 30 meters. If the wires are longer than 30
meters, set standard auto-tuning with the wires connected to improve low-speed torque during sensorless
vector control.
However the effects of voltage drop cause motor-generated torque in the vicinity of rated frequency to be
somewhat lower.
8) Connecting a reactor or surge voltage suppression filter between the inverter and the motor may reduce
motor-generated torque. Setting auto-tuning may also cause a trip (GVP) rendering sensorless vector
control unusable.
8) The following table shows the relationship between the V/F control mode
selection (RV) and the motor constant parameter.
Under normal conditions, be sure to set or adjust the parameters marked with .
When making detailed settings, adjust the parameters marked with c as well, if necessary.
Do not adjust the parameters marked with °, because they are invalid.

1) Setting the electronic thermal protection characteristics selection QNO and
motor electronic thermal protection level 1 VJT, 2 H
The electronic thermal protection characteristics selection QNO is used to enable or disable the motor
overload trip function (QN) and the overload stall function.
While the inverter overload trip (QN) will be in constant detect operation, the motor overload trip (QN)
can be selected using the parameter QNO
Explanation of terms
Overload stall: This is an optimum function for equipment such as fans, pumps and blowers with
variable torque characteristics that the load current decreases as the operating speed
decreases.
When the inverter detects an overload, this function automatically lowers the output
frequency before the motor overload trip QN is activated. This function operates a
motor at frequencies that allow the load current to keep its balance so that the
inverter can continue operation without being tripped.
Note: Do not use the overload stall function with loads having constant torque characteristics (such as
conveyor belts in which load current is fixed with no relation to speed).
[Using standard motors (other than motors intended for use with inverters)]
When a motor is used in the lower frequency range than the rated frequency, that will decrease the cooling
effects for the motor. This speeds up the start of overload detection operations when a standard motor is
used in order to prevent overheating.

Note: If the operation frequency is set to the lower limit frequency, it will increase from 0Hz when power is

operation frequency reaches the lower limit frequency. (Operation at the lower limit frequency)
In this case, the time required for the operation frequency to reach the lower limit frequency can be
shortened by setting HE to the lower limit frequency.
■Adjustment with pulse signals (Parameter-setting example 2)
Set parameters as follows to adjust the frequency in steps of one pulse:
H, H ≤ Pulse On time
H, H = Frequency obtained with each pulse
* The inverter does not respond to any pulses with an ON time shorter than that set with H or

■If two signals are impressed simultaneously
•If a clear single and an up or down signal are impressed simultaneously, priority will be given to the
clear signal.
•If up and down signals are impressed simultaneously, The frequency will change at the specified up
or down rate.
■About the setting of the initial up/down frequency
To adjust the frequency starting at a specified frequency other than 0.0 Hz (default initial frequency)
after turning on the inverter, specify the desired frequency using H (initial up/down frequency).
■About the change of the initial up/down frequency
To make the inverter automatically save the frequency immediately before it is turned off and start
operation at that frequency next time power is turned on, set H (change of initial up/down
frequency) to 1 (which changes the setting of H when power is turned off).
Keep in mind that the setting of H is changed each time power is turned off.
■Frequency adjustment range
The frequency can be set from 0.0Hz to HJ (Maximum frequency). The lower-limit frequency will be
set as soon as the set frequency clearing function (function number 43, 44) is entered from the input
terminal.
■Minimum unit of frequency adjustment

certain amount of voltage is applied to the VIA and VIB input terminals. If you want to reduce the leeway,
set H or H to a larger value. Note that specifying a too large value may cause an output
frequency to be output, even though the operation frequency is 0 (zero) Hz.
* Gain adjustment of VIA and VIB input terminals (H and H)
The inverter is factory-adjusted by default so that the operation frequency can reach the maximum
frequency, even though the voltage and current to the VIA and VIB input terminals are below the
maximum levels. If you want to adjust the inverter so that it will output the maximum frequency at the
maximum voltage and current, set H or H to a smaller value. Note that specifying a too small
value may cause the operation frequency not to reach the maximum frequency, even though the
maximum voltage and current are applied.

example of the operating frequency during power running. During regenerative braking, control is
performed in such a way as to increase the frequency.
•The droop function is activated above the torque current set with H.
•The amount of droop frequency ∆f varies depending on the amount of torque current T1.
Note: If the base frequency XN exceeds 100Hz, count it as 100Hz.
Control is exercised between the starting frequency (H) and the maximum frequency (HJ).
[An example of calculation]
Parameter setting:Base frequency XN=60 (Hz), droop gain H=10 (%)
Droop insensitive torque band H=30 (%)
Droop frequency ∆f (Hz) and operating frequency f1 when command frequency f0 is 50 (Hz) and torque
current T1 is 100 (%) are as follows.
Droop frequency ∆f (Hz)=XN × H × (T1 - H)
=60 (Hz) × 10 (%) × (100 (%) - 30 (%))
=4.2 (Hz)
Operation frequency f1 (Hz) = f0 - ∆f = 50 (Hz) - 4.2 (Hz)=45.8 (Hz)

When using VIB terminal, set H or H respectively to 60 or 61 to put out signals to RY-RC
or FLA-FLB-FLC.
You can also specify a frequency agreement detection range (H).
⇒ For more information, see section 6.3.5.
3) Setting PID control
Set "" or "2" in the extended parameter H (PID control)
(1) Set parameters CEE(acceleration time), and FGE (deceleration time) to the system fitting values.
(2) To limit the output frequency, set parameters WN (upper limit frequency) and NN (lower limit
frequency). If process quantities are set from the operation panel, however, the process quantity setting
range will be limited by the settings of WN and NN.
4) Adjusting the PID control gain level
Adjust the PID control gain level according to the process quantities, the feedback signals and the object to
be controlled.
The following parameters are provided for gain adjustment:

H (P-gain adjustment parameter)
This parameter adjusts the proportional gain level during PID control. A correction value proportional to
the particular deviation (the difference between the set frequency and the feedback value) is obtained
by multiplying this deviation by the parameter setting.
A larger P-gain adjustment value gives faster response. Too large an adjustment value, however,
results in an unstable event such as hunting.

H (D-gain adjustment parameter)
This parameter adjusts the differential gain level during PID control. This gain increases the speed of
response to a rapid change in deviation (difference between the frequency setting and the amount of
feedback).
Note that setting the gain more than necessary may cause great fluctuations in output frequency, and
thus operation to become unstable.
5) Adjusting analog command voltages
To use external analog setting (VIA or VIB) or feedback input (VIA or VIB), perform voltage-scaling
adjustments (input point setting) as required. ⇒ See section 6.5.2 for further details.
If the feedback input data is too small, voltage-scaling adjustment data can also be used for gain adjustment.

6) Setting the time elapsed before PID control starts
You can specify a waiting time for PID control to prevent the inverter from starting PID control before the
control system becomes stable, for example, after start-up.
The inverter ignores feedback input signals, carries out operation at the frequency determined by the amount
of processing for the period of time specified with H and enters the PID control mode after a lapse of
the specified time.

H : Motor rated current
H : Motor no-load current
H : Motor rated speed
H : Speed control response coefficient
H : Speed control stable coefficient
To use vector control, automatic torque boost and automatic energy saving, motor constant setting (motor tuning)
is required. The following two methods are available to set motor constants.
1) Setting V/F control mode selection (RV) and auto-tuning (H) independently
2) Combining the V/F control mode selection (RV) and manual tuning
+Check to be sure that the setting of the parameter XN and that of the parameter XNX agree with the base
frequency (rated rotational speed) and base frequency voltage (rated voltage) of the motor to be operated,
respectively. If not, set the parameters correctly.
+When using the inverter to control the operation of a motor smaller in capacity by one grade or more, be
sure to set the motor rated current setting parameter (H) properly.
+Vector control may not operate properly if the motor capacity differs from the applicable rated capacity of the
inverter by more than two grades.
If current waveforms oscillate during operation, increase the speed control stability factor (H). This is
effective in suppressing oscillation.

H Motor rated current 0.1-200.0 (A)
H Motor rated speed 100-15000 (min-1)
(2)Set H to to before the start of operation. Tuning is performed at the start of the motor.
+Precautions on auto-tuning
(1) Conduct auto-tuning only after the motor has been connected and operation completely stopped.
If auto-tuning is conducted immediately after operation stops, the presence of a residual voltage
may result in abnormal tuning.
(2) Voltage is applied to the motor during tuning even though it barely rotates. During tuning,
“CVP” is displayed on the operation panel.
(3) Tuning is performed when the motor starts for the first time after H is set to .
Tuning is usually completed within three seconds. If it is aborted, the motor will trip with the dis-
play of GVP and no constants will be set for that motor.
(4) High-speed motors, high-slip motors or other special motors cannot be auto-tuned. For these
motors, perform manual tuning using Selection 2 described below.
(5) The resulting insufficient motor torque during tuning could create a risk of machine stalling/falling.
(6) If auto-tuning is impossible or an "GVP" auto-tuning error is displayed, perform manual tuning
with Selection 2.
(7) If the inverter is tripped during auto-tuning because of an output phase failure (GRJQ), check if
the inverter is connected to the correctly. A check for output phase failures is made during auto-
tuning, regardless of the setting of the output phase failure detection mode selection parameter
(H).

obtained by dividing the no-load current specified in the motor's test report by the rated current.

H: Using this parameter along with H, adjust the speed of response to the frequency command.
* How to make adjustments according to the moment of inertia of the load
The moment of inertia of the load (including that of the motor shaft) was set at the factory on the
assumption that it would be three times as large as that of the motor shaft.
Adjust H, H with the ratio of inertia in case load inertia is different from three times
of the motor inertia.
When making the above adjustments, increase or decrease settings in steps of 10% or so while
checking how things change.
Note also that, depending on the settings of H and H, the frequency may exceed
the upper-limit frequency if the inverter is set so as to accelerate the load in the shortest
possible time.

low-speed range, specify a larger value for H. Note that this parameter should be adjusted
only when enough torque cannot be obtained, even though auto-tuning (H=) was made
after the setting of the parameters H through H. Note also that adjusting this
parameter may cause an increase in the no-load current in low-speed range. If the no-load current
exceeds the rated current, do not adjust this parameter.

is above the base frequency (region where the field is weak).

H: Using this parameter along with H adjusts characteristics in a region in which the frequency

* How to make adjustments in a region (region where magnetic field is weak) above the base
frequency
If a heavy load is applied instantaneously (or transiently), the motor may stall before the load
current reaches the current set with the stall prevention level 1 parameter (H). In many
cases, this kind of stall can be avoided by gradually reducing the setting of H.
A drop in supply voltage may cause fluctuations of the load current or vibration of the motor. In
some cases, such phenomena can be eliminated by changing the setting of H to between
80 and 90. However, this may cause an increase in load current, so that it is also necessary to
adjust the setting of the electronic thermal protective level 1 parameter (VJT) properly
according to the motor capacity.
H: There is no need to adjust this parameter under normal conditions. (Do not change the setting,
unless otherwise instructed by Toshiba technical staff)
H: Specify a larger value for H to secure as high an output voltage as possible in a region
(region where magnetic field is weak) above the base frequency. Setting H to a larger value
may cause the motor to vibrate or gears to squeak. If such a phenomenon occurs, do not adjust
this parameter.
H: Specify a larger value for H if switching from a waveform to another results in a considerable
increase in vibration and noise in middle-speed range (region between the start frequency and the
base frequency). If no improvement can be made by specifying a larger value, do not adjust this
parameter.

6.21.2 Using the RS485
■Setting the communication functions
Setting commands and frequencies by communications has priority over sending commands from the
operation panel or the terminal board. Command/frequency setting by communications can therefore be
enabled, irrespective of the setting in the command mode (EOQF) or the frequency setting mode (HOQF).
When inverters are connected to each others, however, in order for slave inverters to recognize frequency
signals from the master inverter as frequency commands, the frequency setting mode selection 1 parameter
(HOQF) provided for each slave inverter needs to be set to 4 (serial communications). Refer to the
COMMUNICATIONS EQUIPMENT USER'S MANUAL for details.
However, when the input terminal function selection parameter is set to 48: SC/LC (Serial/Local selection),
the inverter can be operated with the settings of the command mode (EOQF) or the frequency setting mode
(HOQF) by external input.

"Given away": Only the inverter with the selected inverter number conducts data processing. All other
inverters, even if they have received the data, give it away and stand by to receive the
next data.
* : Use the terminal board to branch the cable.
(1) Data is sent from the host computer.
(2) Data from the computer is received at each inverter and the inverter numbers are checked.
(3) The command is decoded and processed only by the inverter with the selected inverter number.
(4) The selected inverter responds by sending the processing results, together with its own inverter
number, to the host computer.
(5) As a result, only the selected inverter starts operating in accordance with the operation frequency
command by communicating independently.
+For details of the communication function, refer to the separate instruction manual, “VF-FS1 Serial
Communication Function”.
Note : Limit the distance between the common serial optional units and the inverter to 5m.

H : Step-out detection current level
H : Step-out detection time
H : High-speed torque adjustment coefficient
•Function
If the permanent magnet motor (PM motor) steps out and if the exciting current increases (it increases
in such a case) and remains above the value set with H for the period of time set with H,
the inverter will judge the motor to be stepping out and trip it. At that time, the trip message
"UQWV" is displayed.
Title Function Adjustment range Default setting
H Step-out detection current level 10 ~ 150 (%) / (A) 100
H Step-out detection time 0.0: No detection
0.1 ~ 25.0 [s] 0.0
H High-speed torque adjustment coefficient 0.00 ~ 650.0 0.00
Note 1: When using an PM motor, consult your Toshiba dealer, since the inverter is not compatible with all
types of PM motors.
Note 2: The inverter may fail to detect step-out in some cases, because it uses an electrical method to detect
step-out. To avoid detection failures, you are recommended to install a mechanical step-out detector.
Note 3: There is no need adjust H under normal conditions. (Do not change the setting, unless
otherwise instructed by Toshiba technical staff.)

9. Measures to satisfy the standards
9.1 How to cope with the CE directive
In Europe, the EMC directive and the low-voltage directive, which took effect in 1996 and 1997, respectively,
make it obligatory to put the CE mark on every applicable product to prove that it complies with the directives.
Inverters do not work alone but are designed to be installed in a control panel and always used in combination
with other machines or systems which control them, so they themselves are not considered to be subject to the
EMC directive. However, the CE mark must be put on all inverters because they are subject to the low-voltage
directive.
The CE mark must be put on all machines and systems with built-in inverters because such machines and
systems are subject to the above directives. It is the responsibility of the manufacturers of such final products to
put the CE mark on each one. If they are "final" products, they might also be subject to machine-related directives.
It is the responsibility of the manufacturers of such final products to put the CE mark on each one. In order to
make machines and systems with built-in inverters compliant with the EMC directive and the low-voltage directive,
this section explains how to install inverters and what measures should be taken to satisfy the EMC directive.
We have tested representative models with them installed as described later in this manual to check for
conformity with the EMC directive. However, we cannot check all inverters for conformity because whether or not
they conform to the EMC direction depends on how they are installed and connected. In other words, the
application of the EMC directive varies depending on the composition of the control panel with a built-in
inverter(s), the relationship with other built-in electrical components, the wiring condition, the layout condition, and
so on. Therefore, please verify yourself whether your machine or system conforms to the EMC directive.
9.1.1 About the EMC directive
Inverters themselves are not subject to approval for CE marking.
The CE mark must be put on every final product that includes an inverter(s) and a motor(s). The VF-FS1 series of
inverters complies with the EMC directive if an EMI filter recommended by Toshiba is connected to it and wiring is
carried out correctly.
■EMC directive 89/336/EEC
The EMC standards are broadly divided into two categories; immunity- and emission-related standards, each of
which is further categorized according to the operating environment of each individual machine. Since inverters
are intended for use with industrial systems under industrial environments, they fall within the EMC categories
listed in Table 1 below. The tests required for machines and systems as final products are almost the same as
those required for inverters.

9.1.2 Measures to satisfy the EMC directive
This subsection explains what measures must be taken to satisfy the EMC directive.
(1) Insert a recommended EMI filter (Table 2) on the input side of the inverter to reduce and transmission noise
and radiation noise from input cables.
In the combinations listed in Table 2, Inverters are tested in these combination to see if they comply with
transmission noise standards. For inverters used in Japan, it is recommended to use the NF series of noise
filters.
Table 2 lists noise filters recommended for the inverters.

(2) Use shielded power cables, such as inverter output cables, and shielded control cables. Route the cables
and wires so as to minimize their lengths. Keep a distance between the power cable and the control cable
and between the input and output wires of the power cable. Do not route them in parallel or bind them
together, instead cross at right angle.
(3) Install the inverter and the filter on the same metal plate. It is more effective in limiting the radiation noise to
install the inverter in a sealed steel cabinet. Using wires as thick and short as possible, earth the metal plate
and the control panel securely with a distance kept between the earth cable and the power cable.
(4) Route the EMI filter input and output wires apart from each other.
(5) To suppress radiation noise from cables, ground all shielded cables through a noise cut plate.
It is effective to earth shielded cables in the vicinity of the inverter, cabinet and filter (within a radius of 10cm
from each of them). Inserting a ferrite core in a shielded cable is even more effective in limiting the radiation
noise.
(6) To further limit the radiation noise, insert a zero-phase reactor in the inverter output line and insert ferrite
cores in the earth cables of the metal plate and cabinet.

9.1.3 About the low-voltage directive
The low-voltage directive provides for the safety of machines and systems. All Toshiba inverters are CE-marked
in accordance with the standard EN 50178 specified by the low-voltage directive, and can therefore be installed in
machines or systems and imported without problem to European countries.

EN 50178 applies to electrical equipment intended specially for use in power installations, and sets out the
conditions to be observed for electric shock prevention when designing, testing, manufacturing and installing
electronic equipment for use in power installations.
9.1.4 Measures to satisfy the low-voltage directive
When incorporating the inverter into a machine or system, it is necessary to take the following measures so that
the inverter satisfies the low-voltage directive.
(1) Install the inverter in a cabinet and ground the inverter enclosure. When doing maintenance, be extremely
careful not to put your fingers into the inverter through a wiring hole and touch a charged part, which may
occur depending on the model and capacity of the inverter used.
(2) Do not connect two or more wires to the main circuit earth terminal of the inverter. If necessary, install an
additional earth terminal on the metal plate on which the inverter is installed and connect another cable to it.
Or install the EMC plate (attached as standard) and another cable connect to earth terminal on the EMC
plate. Refer to the table 10.1 for earth cable sizes.
(3) Install a non-fuse circuit breaker or a fuse on the input side of the inverter.
9.2 Compliance with UL Standard and CSA Standard
The VF-FS1 models, that conform to the UL Standard and CSA Standard have the UL/CSA mark on the
nameplate.
9.2.1 Compliance with Installation
The VF-FS1 inverter must be installed in a panel, and used within the ambient temperature specification.
⇒ See section 1.4.4.
9.2.2 Compliance with Connection
Use the UL conformed cables (Rating 75 °C or more) to the main circuit terminals (R/L1, S/L2, T/L3, U/T1, V/T2,
W/T3).
Refer to the table of next page about wire sizes.
9.2.3 Compliance with Peripheral devices
Use the UL listed fuses at connecting to power supply.
Short circuit test is performed under the condition of the power supply short-circuit currents in below.
These interrupting capacities and fuse rating currents depend on the applicable motor capacities.

Note 1: Selections for use of the Toshiba 4-pole standard motor with power supply voltage of 200V/400V-50Hz.
Note 2: Choose the MCCB according to the power supply capacity.
For comply with UL and CSA standard, use the fuse certified by UL and CSA.
Note 3: When using on the motor side during commercial-power supply operation, choose the MC with class
AC-3 rated current for the motor rated current.
Note 4: Attach surge killers to the magnetic contactor and exciting coil of the relay.
Note 5: In the case the magnetic contactor (MC) with 2a-type auxiliary contacts is used for the control circuit,
raise the reliability of the contact by using 2a-type contacts in parallel connection.

10.2 Installation of a magnetic contactor
If using the inverter without installing a magnetic contactor (MC) in the primary circuit, use an MCCB (with a
power cutoff device) to open the primary circuit when the inverter protective circuit is activated.
■Magnetic contactor in the primary circuit
To detach the inverter from the power supply in any of the following cases, insert a magnetic contactor
(primary-side magnetic contactor) between the inverter and the power supply.
(1) If the motor overload relay is tripped
(2) If the protective detector (FL) built into the inverter is activated
(3) In the event of a power failure (for prevention of auto-restart)
When using the inverter with no magnetic contactor (MC) on the primary side, install a non-fuse circuit
breaker with a voltage tripping coil instead of an MC and adjust the circuit breaker so that it will be tripped if
the protective relay referred to above is activated. To detect a power failure, use an undervoltage relay or
the like.
Example of connection of a magnetic contactor in the primary circuit
Notes on wiring
•When frequently switching between start and stop, do not use the magnetic contactor on the primary side as
an on-off switch for the inverter.
Instead, stop and start the inverter by using terminals F and CC (forward run) or R and CC (reverse run).
•Be sure to attach a surge killer to the exciting coil of the magnetic contactor (MC).
E6581381
J-4
10
■Magnetic contactor in the secondary circuit
A magnetic contactor may be installed on the secondary side to switch controlled motors or supply
commercial power to the load when the inverter is out of operation.
Notes on wiring
•Be sure to interlock the magnetic contactor on the secondary side with the power supply to prevent commercial
power from being applied to the inverter output terminals.
•When installing a magnetic contactor (MC) between the inverter and the motor, avoid turning the magnetic
contactor on or off during operation. Turning the magnetic contactor on or off during operation causes a current
to rush into the inverter which could lead to malfunction.
10.3 Installation of an overload relay
1) The VF-FS1 inverter has an electronic-thermal overload protective function.
In the following cases, however, an overload relay suitable for the adjustment of the motor electronic
thermal protection level (VJT) and appropriate to the motor used should be installed between the inverter
and the motor.
•When using a motor with a current rating different to that of the corresponding Toshiba general-purpose
motor
•When operating a single motor with an output smaller than that of the applicable standard motor or more
than one motor simultaneously.
2) When using the VF-FS1 inverter to operate a constant-torque motor, such as the Toshiba VF motor, adjust
the protection characteristic of the electronic thermal protection unit (NO) to the VF motor use.
3) It is recommended to use a motor with a thermal relay embedded in the motor coil to give sufficient
protection to the motor, especially when it runs in a low-speed range.

13.2 Restoring the inverter from a trip
Do not reset the inverter when tripped because of a failure or error before eliminating the cause. Resetting the
tripped inverter before eliminating the problem causes it to trip again.
The inverter can be restored from a trip by any of the following operations:
(1) By turning off the power (Keep the inverter off until the LED turns off.)
Note: ⇒ See section 6.17.3 (inverter trip retention selection H) for details.
(2) By means of an external signal (Short circuit between RES and CC on terminal board → Open)
(3) By operation panel operation
(4) By inputting a trip clear signal from a remote input device
(Refer to the remote input device operating manual for details.)
To reset the inverter by operation panel operation, follow these steps.
1. Press the key and make sure that ENT is displayed.
2. Pressing the key again will reset the inverter if the cause of the trip has already been eliminated.
+In case of a trip due to overheating (QJ), the inverter checks the temperature within. Wait until the
temperature in the inverter falls sufficiently before resetting the inverter.
[Caution]
Turning the inverter off then turning it on again resets the inverter immediately. You can use this mode of
resetting if there is a need to reset the inverter immediately. Note, however, that this operation may damage
the system or the motor if it is repeated frequently.

14. Inspection and maintenance
Danger
Mandatory
•The equipment must be inspected every day.
If the equipment is not inspected and maintained, errors and malfunctions may not be discovered
which could lead to accidents.
•Before inspection, perform the following steps.
(1) Shut off all input power to the inverter.
(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (800V DC or more), and check that the voltage to the
DC main circuits (across PA/+ and PC/-) does not exceed 45V.
Performing an inspection without carrying out these steps first could lead to electric shock.
Be sure to inspect the inverter regularly and periodically to prevent it from breaking down because of the environment
of use, such as temperature, humidity, dust and vibration, or deterioration of its components with aging.
14.1 Regular inspection
Since electronic parts are susceptible to heat, install the inverter in a cool, well-ventilated and dust-free place.
This is essential for increasing the service life.
The purpose of regular inspections is to maintain the correct environment of use and to find any sign of failure or
malfunction by comparing current operation data with past operation records.

■ Cautions about cleaning
To clean the inverter, wipe dirt off only its surface with a soft cloth but do not try to remove dirt or stains from
any other part. If stubborn stains persist, remove them by wiping gently with a cloth dampened with neutral
detergent or ethanol.
Never use any of the chemicals in the table below; the use of any of them may damage or peel the coating
away from molded parts (such as plastic covers and units) of the inverter.
Acetone Ethylene chloride Tetrachloroethane
Benzen Ethyl acetate Trichloroethylene
Chloroform Glycerin Xylene
14.2 Periodical inspection
Make a periodical inspection at intervals of 3 or 6 months depending on the operating conditions.
Danger
Mandatory
•Before inspection, perform the following steps.
(1) Shut off all input power to the inverter.
(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (800V DC or more), and check that the voltage to the
DC main circuits (across PA/+ and PC/-) does not exceed 45V.
Performing an inspection without carrying out these steps first could lead to electric shock.
Prohibited
• Never replace any part.
This could be a cause of electric shock, fire and bodily injury. To replace parts, call the local sales
agency.
■Check items
1. Check to see if all screwed terminals are tightened firmly. If any screw is found loose, tighten it again
with a screwdriver.
2. Check to see if all caulked terminals are fixed properly. Check them visually to see that there is no trace
of overheating around any of them.
3. Check all cables and wires for damage. Check them visually.
4. Remove dirt and dust. With a vacuum cleaner, remove dirt and dust. When cleaning, clean the vents
and the printed circuit boards. Always keep them clean to prevent an accident due to dirt or dust.
E6581381
N-3
14
5. If no power is supplied to the inverter for a long time, the performance of its capacity electrolytic
capacitor declines.
When leaving the inverter unused for a long time, supply it with electricity once every two years, for 5
hours or more each, to recover the performance of the capacity electrolytic capacitor. And also check the
function of the inverter. It is advisable not to supply the commercial power directly to the inverter but to
gradually increase the power supply voltage with a transformer, etc.
6. If the need arises, conduct an insulation test on the main circuit terminal board only, using a 500V
insulation tester. Never conduct an insulation test on control terminals other than terminals on the
printed circuit board or on control terminals. When testing the motor for insulation performance, separate
it from the inverter in advance by disconnecting the cables from the inverter output terminals U, V and W.
When conducting an insulation test on peripheral circuits other than the motor circuit, disconnect all
cables from the inverter so that no voltage is applied to the inverter during the test.
Note: Before an insulation test, always disconnect all cables from the main circuit terminal board and
test the inverter separately from other equipment..
500V
(megger)
R/L 1 S/L 2 T/L 3 U/T 1 V/T 2 W/T 3
7. Never test the inverter for pressure. A pressure test may cause damage to its components.
8. Voltage and temperature check
Recommended voltmeter : Input side ... Moving-iron type voltmeter ( )
Output side ... Rectifier type voltmeter ( )
It will be very helpful for detecting a defect if you always measure and record the ambient temperature
before, during and after the operation.
■Replacement of expendable parts
The inverter is composed of a large number of electronic parts including semiconductor devices. The
following parts deteriorate with the passage of time because of their composition or physical properties. The
use of aged or deteriorated parts leads to degradation in the performance or a breakdown of the inverter. To
avoid such trouble, the inverter should be checked periodically.
Note: Generally, the life of a part depends on the ambient temperature and the conditions of use. The life
spans listed below are applicable to parts when used under normal environmental conditions.
E6581381
N-4
14
1) Cooling fan
The fan, which cools down heat-generating parts, has a service life of about 30,000 hours (about 2 or 3
years of continuous operation). The fan also needs to be replaced if it makes a noise or vibrates
abnormally.
2) Smoothing capacitor
• Main circuit
The smoothing capacitors applied to this inverter in the main circuit DC section are film type
capacitors. Those life time in design value is 15 years, but it is recommended to replace them after it
is used for about 10 years under normal conditions. Since the smoothing capacitors are mounted on
a printed circuit board, it needs to be replaced together with the circuit board.
• Control circuit
The smoothing aluminum electrolytic capacitor degrades in performance because of ripple current,
etc. The life time in design value is 15 years, but it is recommended to replace them after it is used for
about 10 years under normal conditions. Since the smoothing capacitors are mounted on a printed
circuit board, it needs to be replaced together with the circuit board.
<Criteria for appearance check>
•Absence of liquid leak
•Absence of case dampaged
Note: The operation time is helpful for roughly determining the time of replacement. For the replacement of
parts, contact your nearest Toshiba inverter distributor. For safety’s sake, never replace any part on
your own. (Parts replacement alarms can be known by monitor and alarm output, if it is set.
⇒ See section 6.17.14.
■Standard replacement cycles of principal parts
As guides, the table below lists part replacement cycles that were estimated based on the assumption that
the inverter would be used in a normal use environment under normal conditions (ambient temperature,
ventilation conditions, and energizing time). The replacement cycle of each part does not mean its service
life but the number of years over which its failure rate does not increase significantly.
Part name Standard

14.3 Making a call for servicing
For the Toshiba service network, refer to the back cover of this instruction manual. If defective conditions are
encountered, please contact the Toshiba service section in charge via your Toshiba dealer.
When making a call for servicing, please inform us of the contents of the rating label on the right panel of the
inverter, the presence or absence of optional devices, etc., in addition to the details of the failure.
14.4 Keeping the inverter in storage
Take the following precautions when keeping the inverter in storage temporarily or for a long period of time.
1. Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder.
2. If the printed circuit board in your inverter has an anti-static cover (black cover), do not leave it detached
from the circuit board during storage. The cover must be detached before turning on the inverter.
3. If no power is supplied to the inverter for a long time, the performance of its capacity electrolytic capacitor
declines.
When leaving the inverter unused for a long time, supply it with electricity once every two years, for 5 hours
or more each, to recover the performance of the capacity electrolytic capacitor. And also check the function
of the inverter. It is advisable not to supply the commercial power directly to the inverter but to gradually
increase the power supply voltage with a transformer, etc.

16. Disposal of the inverter
Warning
Mandatory
•If you throw away the inverter, have it done by a specialist in industry waste disposal(*). If you throw
away the inverter by yourself, this can result in explosion of capacitor or produce noxious gases,
resulting in injury.
(*) Persons who specialize in the processing of waste and known as "industrial waste product collectors
and transporters" or "industrial waste disposal persons. "If the collection, transport and disposal of
industrial waste is done by someone who is not licensed for that job, it is a punishable violation of the
law. (Laws in regard to cleaning and processing of waste materials)
For safety’s sake, do not dispose of the disused inverter yourself but ask an industrial waste disposal agent.
Disposing of the inverter improperly could cause its capacitor to explode and emit toxic gas, causing injury to persons.
