Notes on the application

1.4.1

Motors

When the VF-S9 and the motor are used in conjunction, pay attention to the following items.

Warning

1
Mandatory

Use an inverter that conforms to the specifications of the three-phase induction motor and power supply
being used. If the inverter being used does not conform to those specifications, not only will the threephase induction motor not rotate correctly, but it may causes serious accidents through overheating and
fire.

Comparisons with commercial power operation.
The VF-S9 Inverter employs the sinusoidal PWM system. However, the output voltage and output current do not assume a precise sine wave, 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.
If you want to run continuously low speed operations at rated torque, please use the VF motor made
especially for Toshiba inverter. When operating in conjunction with a VF motor, you must change the
)".
inverter's motor overload protection level to "VF motor use (

Adjusting the overload protection level
The VF-S9 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 that 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
that such operation will exceed the motor's mechanical strength limits and the bearing limits so that 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.

A-10

E6580757

Extremely low loads and low inertia loads
The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of
50 percent 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 under the load and motor combinations shown below.
Combined with a motor that exceeds applicable motor ratings recommended for the inverter
Combined with special motors such as explosion-proof motors
To deal with the above lower the settings of inverter carrier frequency.
(Do not set to 2.2kHz or lower during vector control).
Combined with couplings between load devices and motors with high backlash
In this case, set the S-pattern acceleration/deceleration function and adjust the response time (inertial
moment setting) during vector control or switch to V/f control.
Combined with loads that have sharp fluctuations in rotation such as piston movements
In this case, adjust the response time (inertial moment setting) during vector control or switch to V/f
control.

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.

Loads that generate negative torque
When combined with loads that generate negative torque the protection for overvoltage and overcurrent
on the inverter will go into operation and may cause a trip. For this kind of situation, you must install a
dynamic braking resistor, etc. that complies with the load conditions.

Motor with brake
If a motor with brake is connected directly to the output side of the inverter, the brake will not release
because voltage at startup is low. Wire the brake circuit separately from the motor's main circuits.

In circuit configuration 1, the brake is turned on and off through MC2 and MC3. If the circuit is config-

ured in some other way, the overcurrent trip may be activated because of the locked rotor current when
the brake goes into operation. Circuit configuration 2 uses low-speed signal RY to turn on and off the
brake. Turning the brake on and off with a low-speed signal may be better in such applications as elevators. Please confer with us before designing the system.

1.4.2

Inverters

Protecting inverters from overcurrent
The inverter has an overcurrent protection function. However because the programmed current level is
set to the inverter's maximum applicable motor, if the motor is one of small capacity and it is in operation, the overcurrent level and the electronic thermal protection must be readjusted. If adjustment is
necessary, see 5-14 in Chapter 5, and make adjustments as directed.

Inverter capacity
Do not operate a large capacity motor with a small capacity (kVA) inverter even with light loads. Current
ripple will raise the output peak current making it easier to set off the overcurrent trip.

Power factor improving capacitors
Power factor improving capacitors cannot be installed on the output side of the inverter. When a motor
is run that has a power factor improving 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.

■ Disposal
If an inverter is no longer usable, dispose of it as industrial waste.

1.4.3

What to do about 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 leak 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
Leak current may flow not just through the inverter system but also through ground wires to other systems. Leak current will cause earth leakage breakers, leak 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 amounts during current detection with the CT.

Remedies:
1.Reduce PWM carrier frequency.
The setting of PWM carrier frequency is done with the parameter

2.Use high frequency remedial products (Schneider Toshiba electric corporation: Esper Mighty
Series) for earth leakage breakers. If you use equipment like this, there is no need to reduce
the PWM carrier frequency.
3.If the sensors and CRT are affected, it can be remedied using the reduction of PWM carrier
frequency described in 1 above, but if this cannot be remedied since there is an increase in the
motor's magnetic noise, please consult with Toshiba.

Leak current path across wires

(1)

Thermal relays
The high frequency component of current leaking into electrostatic capacity between inverter output 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 (3.7kW) models, because the leak current will increase in proportion to the motor rating.

A-14

E6580757

Remedies:
1.Use the electronic thermal built into the inverter.
The setting of the electronic thermal is done using parameter
,
(
).
2.Reduce the inverter's PWM carrier frequency. However, that will increase the motor's magnetic
noise. Use parameter
for setting the PWM carrier frequency.
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.

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 (3.7kW 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 output 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.
2.Use the monitor functions built into the inverter.
Use the monitor functions on the panel built into the inverter to check current values.

■ How to install
Danger
• Do not install and operate the inverter if it is damaged or any component is missing.
This can result in electric shock or fire. Please consult your local agency for repairs.
Prohibited

1
Mandatory

• Must be installed in nonflammables such as metals.
The rear panel gets very hot so that if installation is 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. cuts off input
power then engages mechanical brakes).
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.

■ Installation location
Select a location with good indoor ventilation, place lengthwise in the vertical direction and attach to a metal
wall surface.
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 of the
ventilation seals on top of the inverters and operate at 40°C or less (model of 3.7kW or less). Operate at
50°C or less (model of 5.5kW or more).

area that presents a potential problem, please consult with Toshiba before doing so.

■ Calorific values of the inverter and the required ventilation
The energy loss when the inverter converts power from AC to DC and then back to AC is about 5 percent. 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.

■ 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 (

A-19

E6580757
• Install surge suppressor on any magnetic contactor and relay coils used around the inverter.
• Install noise filters if necessary.
• Install EMC plate (attached as standard) and shielded wires fit with the EMC plate.

EMC plate

■ Installing more than one unit in a cabinet
If you are installing two or more inverters in one cabinet, pay attention to the following.
• Ensure a space of at least 5 centimeters on the left and right sides of the inverters.
* If the inverters are horizontally arranged with no space between them (side-by-side installation), remove the ventilation seals on top of the inverters and operate at 40°C or less (model of 3.7kW or less)
or 50°C (model of 5.5kW or more).
• 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.

Prohibited

• Don’t stick your fingers into openings such as cable wiring hole and cooling fan covers. This can result
in electric shock or other injury.
• Don't place or insert any kind of object into the inverter (electrical wire cuttings, rods, wires). This can
result in electric shock or fire.
• Do not allow water or any other fluid to come in contact with the inverter. That may result in electric
shock or fire.

Warning
• When transporting or carrying, do not hold by the front panel covers.
The covers may come off and the unit will drop out resulting in injury.
Prohibited

2.1

Cautions on wiring
Danger
• Never remove the front cover when power is on or open door if enclosed in a cabinet.
The unit contains many high voltage parts and contact with them will result in electric shock.

Prohibited

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. This can
result in electric shock or other injury.
• Electrical construction work must be done by a qualified expert.
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-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.

B-1

E6580757

Danger
• 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.
Be Grounded

Warning

• 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.
Prohibited

■ 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 VFS9 are the same.
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 [former type 3 ground]; 400V class: C
type ground [former special type 3 ground]).
Use as large and short a ground wire as possible and wire it as close as possible to the inverter.
• See the table in 9-1 for wire sizes.
• 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 connect resistors to DC terminals (across PA-PC or across PO-PC).
It could cause a fire.
Connect resistors as directed in the instructions for "Installing separate braking resistors."
• 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.
• Securely connect to ground with a ground wire.
If a secure connection to ground is not made, this could cause electric shock or fire when a malfunction
or leak current occurs.

logic switching of input output terminals
Current flowing out turns control input terminals on. These are called sink logic terminals (The end of Type
- form : AN / WN). The general used method in Europe is source logic in which current flowing into the input terminal turns it on(The end of Type - form : WP).

3. Operations
Danger

Prohibited

Mandatory

• Do not touch inverter terminals when electrical power is connected 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.
• 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.

Warning
• Do not touch heat radiating fins or discharge resisters. These device are hot, and you'll get burned if
you touch them.
Contact
prohibited
• Always observe the permissible operating ranges of motors and other equipment (see the instruction
manual for the motor).
If these ranges are not observed, it could result in injury.

Explanation of terms
Overload stall: When the inverter detects an overload, this function automatically lowers the output
frequency before the motor overload trip
is activated. The soft stall function
allows the drive to run with balanced load current frequency without a trip. 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.
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.

Caution

Mandatory

• Stand clear of motors and mechanical equipment
If the motor stops due to a momentary power failure, the equipment will start suddenly when power is
restored. This could result in unexpected injury.
• Attach warnings about sudden restart after a momentary power failure on inverters, motors and equipment to prevent accidents in advance.
•

Function
The F301 parameter detects the rotating speed and rotational direction of the motor during coasting
in the event of momentary power failure, and then after power has been restored, restarts the motor
smoothly (motor speed search function). This parameter also allows commercial power operation to
be switched to inverter operation without stopping the motor.

This function is effective when the motor is under a momentary power failure or coasting status and is reversing for some external reason.

F-24

E6580757

Application!!
• A waiting time of 200 to 1,000msec is preset to allow the residual voltage in the motor to decrease
to a certain level during restart. For this reason, the start-up takes more time than usual.
• Use this function when operating a system with one motor connected to one inverter. This function
may not operate properly in a system configuration with multiple motors connected to one inverter.
Application to a crane or hoist
The crane or hoist may have its load moved downward during the above waiting time from input of
the operation starting command to the restart of the motor. To apply the inverter to such machines,
therefore, set the auto-restart control mode selection parameter to "0" (Disabled), and avoid using
the retry function. If retry function is enabled the load could move downward causing damage and
or injury.

: Motor secondary constant

: Magnification of load inertial moment

To use vector control, automatic torque boost and automatic energy-saving, motor constant setting (motor tuning)
is required. The following three methods are available to set motor constants (for automatic torque boosting,
however, two methods are available):
) for setting the V/F control mode selection
1)
Using the automatic torque boost (
) and auto-tuning (

Sensorless vector control may not operate properly if the motor capacity differs from the applicable rated capacity
of the inverter by more than two grades.

This is the easiest of the available methods. It conducts vector control and auto-tuning at the same time.

Set the automatic torque boost parameter (

to " " if the motor capacity is one size smaller than the applicable rated capacity of the inverter.

✩ 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.
(3) Tuning is usually completed within three seconds. If it is aborted, the motor will trip with the display of "
" 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 3 described below.
(5) Provide cranes and hoists with sufficient circuit protection such as mechanical braking. Without
sufficient circuit protection, the resulting insufficient motor torque during tuning could create a risk
of machine stalling/falling.
(6) If auto-tuning is impossible or an "
" auto-tuning error is displayed, perform manual tuning
with Selection 3.

[Selection 3: Setting vector control and manual tuning independently]
If an "
" tuning error is displayed during auto-tuning or when vector control characteristics are to be
improved, independent motor constants can be set.

Setting procedure
Adjust the following parameters:
: Select " " to set the motor constant independently using the

∼

parameters.

: Set the slip frequency for the motor. A higher slip frequency reduces motor slipping correspondingly. (The slip frequency can be set on the basis of test records of the motor.)
: Adjust the primary resistive component of the motor. Decreases in torque due to a possible voltage drop during low-speed operation can be suppressed by setting a large value in this parameter.
(Perform adjustments according to the actual operation.)
: Adjust the secondary component of the motor. This parameter is enabled only when
is
set to " ". A larger adjustment value gives more slip correction. (Perform adjustments according
to the actual operation.)
: Set the excitation inductance for the motor. A larger inductance creates a smaller no-load current.
(Perform adjustments according to the actual operation.)
: Set a load inertia moment with a multiple of the motor inertia moment. A transient response can
be adjusted. A larger adjustment value reduces inertial overshoot, and thus prevents the occurrence of an overcurrent and an overvoltage, correspondingly.
: Set "1" if the rated capacity of the motor is one size smaller than that of the inverter.
* Sensorless vector control may not operate properly if the motor capacity differs from the appli-

cable rated capacity of the inverter by more than two grades.

Refer to the COMMUNICATIONS EQUIPMENT USER'S MANUAL for details.
•

Function
The VFS9 Series allows a data communication network to be constructed for exchanging data between
a host computer or controller (referred to collectively as the computer) and the inverter by connecting an
optional RS232C or RS485 communication conversion unit.

The following functions are enabled by data communication between the computer and inverter
(1) Monitoring inverter status (such as the output frequency, current, and voltage)
(2) Sending RUN, STOP and other control commands to the inverter
(3) Reading, editing and writing inverter parameter settings

Data can be exchanged between one computer and one inverter.

Data can be exchanged between the computer and a maximum of 64 inverters.
✩ The following are available as common serial optional units:
• RS232C communications conversion unit (Model: RS2001Z)
Communications cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)
• RS485 communication conversion unit with terminal board (Model: RS4001Z)
Communication cable (Model: CAB0011, 1m long; CAB0013, 3m long; or CAB0015, 5m long)
Note 1.: Limit the distance between the common serial optional units and the inverter to 5m.
2.: Set Data transfer speed to 9600 bps or less if data exchange between the common serial optional units
and the inverter.

computer to inverter No. 3:
Wiring
Data (host → INV)

Given away

Response data (INV → host)

Given away

Host computer

"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)
(2)

Data is sent from the host computer.
Data from the computer is received at each inverter and the inverter numbers are checked.

(3)
(4)

The command is decoded and processed only by the inverter with the selected inverter number.
The selected inverter responds by sending the processing results, together with its own inverter
number, to the host computer.
As a result, only the selected inverter starts operating in accordance with the operation frequency

9. Taking measures to satisfy
the CE/UL directive
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. If they are "final" products, they might also be subject to machinerelated 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 lowvoltage 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

The CE mark must be put on every final product that includes an inverter(s) and a motor(s). The VF-S9 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.

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 radiation and transmission noises. In the combinations listed in Table 2, inverters were checked for conformity with the EMC directive. 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.

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.
Route the EMI filter input and output wires apart from each other.
To limit the radiation noise from cables, earth each shielded cable to the metal 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.
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.

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.
Applicable standard: EN 50178
Electronic equipment for use in power installations
Pollution level: 2 (5.2.15.2)
Overvoltage category: 3
200V class - 3.0mm (5.2.16.1)
400V class - 5.5mm (5.2.16.1)
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) When installing the inverter outside the cabinet, provide a protective means for the inverter's wiring hole to
prevent workers from putting their fingers through the hole and touching an electrically-charged part in the
inverter.
(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 on the input side of the inverter.

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.
If using a braking resistor or braking resistor unit, install a magnetic contactor (MC) or non-fuse circuit breaker
with a power cutoff device to the power supply of the inverter, so that the power circuit opens when the failure
detection relay (FL) in the inverter or the external overload relay is activated.

■ Magnetic contactor in the primary circuit
A magnetic contactor installed in the power supply circuit of the inverter cuts off the power supply to the circuit and prevents the inverter from restarting in case of a power failure, a trip of the overload relay (Th-Ry)
or the activation of the inverter protective circuit.
In addition, if the FL contact of the failure detection relay in the VF-S9 is connected to the operation circuit
of the magnetic contactor on the primary side, the magnetic contactor (MC) will be tripped when the inverter
protective circuit is activated.

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).

■ 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)

2)
3)

The VF-S9 inverter has an electronic-thermal overload protective function. In the following cases, however,
the activation level of the electronic thermal protection unit must be adjusted and an overload relay suitable
for the motor 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
When using the VF-S9 inverter to operate a constant-torque motor, such as the Toshiba VF motor, adjust
the protection characteristic of the electronic thermal protection unit to the VF motor use.
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.

Improves the power factor more than the input reactor. When the facility applying the
inverter requires high reliability, it is recommended to use the DC reactor with an input reactor effective for external surge suppression.
* An inverter unit of 200V-3.7kW or less is connected to a reactor selected on page J-8, 9
to conform “Guides of limits for harmonics current emissions on general purpose
inverter having an input current up to and including 20A per phase” by the Japan Electrical Manufacturers’ Association.
These types of filters are not necessary because all single-phase 200V or 3-phase 400V
models and 3-phase 200V, 5.5kW or 7.5kW models have a built-in EMI noise filter, conforming to Class A, as standard. But install these filters if necessarily of noise reduction
move and more.
• Effective to prevent interference in audio equipment used near the inverter.
• Install on the input side of the inverter.
• Provided with wide-range attenuation characteristics from AM radio bands to near
10MHz.
• Use when equipment readily affected by noise is installed in the peripheral area.
• Effective to prevent interference in audio equipment used near the inverter.
• Effective in noise reduction on both input and output sides of the inverter.
• Provided with attenuation characteristics of several dB in frequencies from AM radio
bands to 10MHz.
• For noise countermeasures, insert on the secondary side of the inverter.
High-attenuation EMI noise filter requiring only small space; mounted on the rear side of
the inverter. This filter can be installed to conform to the following classes of EMC standard EN5501 Group 1.
3-phase 200V models excluding those of 5.5/7.5kW : Conform to Class A.
All models other than above
: Conform to Class B.
Use when rapid deceleration or stop is frequently required or when it is desired to reduce
the deceleration time with large load. This resistor consumes regenerative energy during
power generation braking.
• Braking resistor – With (resistor + protective thermal relay) built in.
Use an insulation-reinforced motor or install the surge voltage restraint filter to prevent
degrading motor insulation caused by surge voltage generation depending on cable
length and wiring method, or use of a 400V class motor driven with an inverter.

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) Refer to 6.15.3 (inverter trip retention selection
) for details.
(2) By means of an external signal (Short-circuiting of control terminals RST and CC)

(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.

In the case of a trip due to overheating (

), 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.

13.4 How to determine the causes of other problems
The following table provides a listing of other problems, their possible causes and remedies.
Problems
The motor runs in the
wrong direction.
The motor runs but its
speed does not change
normally.

The motor does not accelerate or decelerate
smoothly.
A too large current flows
into the motor.
The motor runs at a
higher or lower speed
than the specified one.

The motor speed fluctuates during operation.

Parameter settings cannot be changed.

Causes and remedies
• Invert the phases of the output terminals U, V and W.
• Invert the forward/reverse run-signal terminals of the external input device. (See
6.3 "Assignment of functions to control terminals".)
• The load is too heavy.
Reduce the load.
• The soft stall function is activated.
Disable the soft stall function. (See 5.14.)
• The maximum frequency
and the upper limit frequency
are set too low.
Increase the maximum frequency
and the upper limit frequency
.
• The frequency setting signal is too low.
Check the signal set value, circuit, cables, etc.
• Check the setting characteristics (point 1 and point 2 settings) of the frequency
setting signal parameters. (See 6.5.)
• If the motor runs at a low speed, check to see that the stall prevention function is
activated because the torque boost amount is too large.
Adjust the torque boost amount (
) and the acceleration time (
). (See
5.12 and 5.1.)
• The acceleration time (
) or the deceleration time (
) is set too short.
Increase the acceleration time (
) or the deceleration time (
).
• The load is too heavy.
Reduce the load.
• If the motor runs at a low speed, check whether the torque boost amount is too
large. (See 5.13.)
• The motor has an improper voltage rating.
Use a motor with a proper voltage rating.
• The motor terminal voltage is too low.
Check the setting of the base frequency voltage parameter (
). (See
6.12.6.)
Replace the cable with a cable larger in diameter.
• The reduction gear ratio, etc., are not set properly.
Adjust the reduction gear ratio, etc.
• The output frequency is not set correctly.
Check the output frequency range.
• Adjust the base frequency. (See 5.11.)
• The load is too heavy or too light.
Reduce the load fluctuation.
• The inverter or motor used does not have a rating large enough to drive the
load.
Use an inverter or motor with a rating large enough.
• Check whether the frequency setting signal changes.
• If the V/F control selection parameter
is set at 3, check the vector control
setting, operation conditions, etc. (See 5.12.)
• Change the setting of the parameter
(prohibition of change of parameter
setting) to (permitted) if it is set at (prohibited).
For reasons of safety, some parameters cannot be reprogrammed while the

14. Inspection and maintenance
Danger

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 for at least ten minutes and check 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-PC) does not exceed 45V.
Performing an inspection without carrying out these steps first could lead to electric shock.
• When using switchgear for the inverter, it must be installed in a cabinet.
Failure to do so can lead to risk of electric shock and can result in death or serious injury.

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.

1. Something unusual in the installation environment
2. Something unusual in the cooling system
3. Unusual vibration or noise
4. Overheating or discoloration
5. Unusual odor
6. Unusual motor vibration, noise or overheating

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 for at least ten minutes and check 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-PC) does not exceed 45V.
Performing an inspection without carrying out these steps first could lead to electric shock.
• Never replace any part. This could be a cause of electric shock, fire or bodily injury. To replace parts,
call the local sales agency.

Prohibited

■ 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 crimped terminals are fixed properly. Check them visually to see that there is no trace
of overheating around any of them.
3. Check visually all cables and wires for damage.
4. With a vacuum cleaner, remove dirt and dust, especially from the vents and the printed circuit boards.
Always keep them clean to prevent an accident due to dirt or dust.
5. When leaving the inverter unused for a long time, check it for functioning once every 2 years or so by
supplying it with electricity for at least 5 hours with the motor disconnected. It is advisable not to supply
the commercial power directly to the inverter but to gradually increase the power supply voltage with a
transformer.
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.

N-2

E6580757
(Note)

Before an insulation test, always disconnect all cables from the main circuit terminal board
and test the inverter separately from other equipment.

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.
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
The smoothing aluminum electrolytic capacitor in the main circuit DC section degrades in performance
because of ripple currents, etc. It becomes necessary to replace the capacitor after it is used for about
5 years under normal conditions. If your inverter is intended for a 3.7kW or smaller motor, replace the
smoothing capacitor together with the printed circuit board on which it is mounted.

• Absence of liquid leak
• Safety valve in the depressed position
• Measurement of electrostatic capacitance and insulation resistance

N-3

E6580757
The operation time is helpful for roughly determining the time of replacement. For the replacement of parts,
contact the service network or Toshiba branch office printed on the back cover of this instruction manual.

■ Standard replacement cycles of principal parts
The table below provides a listing of the replacement cycles of parts when used under normal conditions
(average ambient temperature: 30°C, load factor: not more than 80%, operation time: 12 hours per day).

Note) The life of a part greatly varies depending on the environment of use.

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.
2.

Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder.
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, though the cover must be detached before turning on the inverter.
If no power is supplied to the inverter for a long time, the performance of its large-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 large-capacity electrolytic capacitor and also to 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.
