„ Limits in purpose
This inverter is used for controlling speeds of three-phase induction motors in general industrial use.
Single-phase power input is output by the inverter as 3-phase output and cannot drive a single-phase motor.
Safety precautions
The inverter cannot be used in any device that would present danger to the human body or from which
malfunction or error in operation would present a direct threat to human life (nuclear power control
device, aviation and space flight control device, traffic device, life support or operation system, safety
device, etc.). If the inverter is to be used for any special purpose, first get in touch with the supplier.
This product was manufactured under the strictest quality controls but if it is to be used in critical
equipment, for example, equipment in which errors in malfunctioning signal output system would cause
a major accident, safety devices must be installed on the equipment.
Do not use the inverter for loads other than those of properly applied three-phase induction motors in
general industrial use. (Use in other than properly applied three-phase induction motors may cause an
accident.)

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 etc.).
This can result in electric shock or fire.
• Do not allow water or any other fluid to come in contact with the inverter.
This can result in electric shock or fire.
• After replacing the terminal block cover, turn the input power on.
Turning on the input power without replacing the terminal block cover may lead to electric
shock.
• 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 since there is a
possibility of malfunction caused by leaks, dust and other material. If power is left on with
the inverter in that state, it may result in fire.

Warning
Instruction
• Must be used in the environmental conditions prescribed in the instruction manual.
Use under any other conditions may result in malfunction.
• 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 use the inverter without the terminal block cover. This can result in electric shock.
Failure to do so can lead to risk of electric shock and can result in death or serious injury.
• 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.
Caution
Prohibited
Instruction
• 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.
• Do not install in any area where the unit would be subject to large amounts of vibration.
That could result in the unit falling, resulting in injury.
• 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.

„ Wiring
Warning
Prohibited
• Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3).
That will destroy the inverter and may result in fire.
• Do not connect resistors to the DC terminals (across PA/+ - PC/- or PO-PC/-).
That may cause a fire.
• Within 15 minutes after turning off input power, do not touch wires of devices (MCCB)
connected to the input side of the inverter.
That could result in electric shock.
• When supplying power from a wall socket, do not exceed the rated capacity of the socket.
Otherwise, this may generate excessive heat which can start a fire.
Warning
Instruction
• Electrical installation 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) Turn off all input power.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage (400VDC 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.
• Check to make sure that the input power voltage is +10%, -15% of the rated power
voltage written on the rating label (±10% when the load is 100% in continuous operation).
If the input power voltage is not +10%, -15% of the rated power voltage (±10% when the
load is 100% in continuous operation) this may result in fire.
• 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.

Note 1) The EMC plate is optional.
2) Grounding capacitor switch
Single-phase 240 V models have a built-in high-attenuation noise filter and are grounded via a capacitor.
A switch makes for easy switching to reduce leakage current from the inverter and the load on the
capacitor. However, be careful, as reducing the load means non-conformity with the EMC standard on
the inverter itself. Always do switching with the power off.
Pressing this switches the grounding capacitor's capacity from small
to large. (Default setting)
Pulling this switches the grounding capacitor's capacity from large to
small. This reduces the leakage current.

Notes on the application
1.4.1
Motors
When the VF-nC3 and the motor are used in conjunction, pay attention to the following items.
Caution
1
Mandatory
Use an inverter that conforms to the specifications of power supply and three-phase induction motor
being operated. 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-nC3 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.
Adjusting the overload protection level
The VF-nC3 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 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.
A-12
E6581595
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 for the inverter
⋅ Combine with a much smaller motor according to the applicable motor rating of 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 or switch to V/f control mode.
⋅ 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.
Load that produces regenerative torque
When combined with a load that produces regenerative torque, the overvoltage or overcurrent
protection function may be activated to trip the inverter.
A-13

E6581595
Motors with a brake
When motors with a brake are directly connected to the inverter's output, the brake cannot be released
at startup because of low voltage. Wire the brake circuit separately from the main circuit.

In circuit diagram 1, the brake is turned on and off through MC2 and MC3. If you do not wire it as shown
in diagram 1, an over-current trip may occur because of a bound current during brake operation.
(Example of running preparation ST assigned to terminal S2.)
In circuit diagram 2, the brake is turned on and off by using low-speed signal OUT.
In some situations, such as with elevators, turning the brake on and off with a low-speed signal may be
appropriate. Be sure to contact us before designing your system.
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 5.13, 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.
A-14
E6581595
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 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
MCCB2 to MCCBn+1 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 behind MCCB2 to
MCCBn+1.
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.

What to do about the leakage current
Caution
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) Leakage current from the inverter main unit
Some of these inverters are equipped with a ground capacitor compliant with the EMC
directive which gives them a comparatively higher value than a normal inverter. Take this
into consideration when selecting a leakage breaker.
For details, see "Leakage current" (E6580977) in the separate user manual.
(2) 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 TV screen or
display of incorrect current detection with the CT.

Remedies:

2.Reduce PWM carrier frequency.
The setting of PWM carrier frequency is done with the parameter .
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 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), because the leakage current will increase in proportion to the motor rating.
Remedies:
1.Use the electronic thermal built into the inverter. (See 3.5)
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.
The setting of PWM carrier frequency is done with the parameter . (See 6.11 in E6581595)
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.

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), because the leakage 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 10V full scale.
0-20mAdc (4-20mAdc) can be also output. (See 5.6)
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 8.2.1)

Prohibited
Mandatory
• 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.
• 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.
Caution
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.
(1) Normal installation
Select an indoor location with good ventilation, and then install it upright on a flat metal plate.
When installing multiple inverters, leave at least 5 cm of space between each inverter and install them
aligned horizontally.
When using the inverter in locations with temperatures above 40°C, remove the caution plate (sticker) on top
of the inverter before use. Current reduction is necessary in locations that exceed 50°C.

for air passage.
Note: Do not install in any location where there is high humidity or high temperatures and where there are
large amounts of dust, metallic fragments and oil mist.
„ 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.

„ Panel designing taking into consideration the effects of noise
1
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 ( ).
• Install surge suppressor on any magnetic contactor and relay coils used around the inverter.
• Install noise filters if necessary.
• To comply with the EMC directives, install the optional EMC plate and fix the shield to it.
• Install EMC plate and use shielded wires.

„ 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, or 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.

• The following steps must be performed before wiring.
(1) Shut off all input power.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage (400VDC 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.

Warning
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.
Caution
2
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 VFnC3 are the same. (See 6.19.3)
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 (240V voltage class: D 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
Warning
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/-, or between PO and PC/-).
It could cause a fire.
See 6.13.4 for the connection of a resistor.
• First shut off input power and wait at least 15 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 VI terminal between analog input and logic contact
input
The functions of the VI terminal can be selected between analog input and logic contact input by changing
parameter settings (). (Factory default setting: Analog input 0-10V)
When using this terminal as logic contact input terminal in a sink logic circuit, be sure to insert a resistor
between the P24 and VI terminals. (Recommended resistance: 4.7KΩ-1/2W)
If no resistor is inserted, logic contact input will be left always ON, which is very dangerous.
Switch between analog input and logic contact input before connecting the terminals to the control circuit
terminals. Otherwise the inverter or devices connected to it may be damaged.
The figure on the right shows an example
of the connection of input terminals VI when
they are used as contact input terminals.
This example illustrates the connection when
the inverter is used in sink (Negative) logic mode.

3. Operations
Caution
Prohibited
Instruction
• 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.
• Turn the input power on only after attaching the terminal block cover (i.e., after closing the cabinet
doors).
If the input power is turned on without the terminal block cover attached (i.e., without closing the
cabinet doors), this may result in electric shock.
• 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 the input power on only after attaching the terminal block cover.
When enclosed inside a cabinet and used with the terminal block cover removed, always close the
cabinet doors first and then turn the power on. If the power is turned on with the terminal block cover or
the cabinet doors open, this 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.
Caution
• Do not touch heat radiating fins or discharge resistors.
These device are hot, and you'll get burned if you touch them.
Contact
prohibited
Prohibited
• Observe all permissible operating ranges of motors and mechanical equipment. (Refer to the motor's
instruction manual.)
Not observing these ranges may result in injury.

„ Adjusting the meter in inverter stop state
• Adjustment of output current (=1)
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  to  for fixed output 1 (output current 100% equivalent), a signal of absolute
values will be output (inverter's rated current = 100%). In this state, adjust the meter with the  (Meter
adjustment) parameter.
Similarly, if you set  to  for fixed output 2 (output current 50% equivalent), 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  to  (output current).
• Other adjustments ( = ,  - , , , )
 = : When fixed output 3 (other than the output current) is set, a signal of the the value for

1) Setting the electronic thermal protection characteristics selection  and
motor electronic thermal protection level 1 , 2 
The electronic thermal protection characteristics selection  is used to enable or disable the motor
overload trip function () and the overload stall function.
While the inverter overload trip () will be in constant detect operation, the motor overload trip ()
can be selected using the parameter 
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  is activated. With this function,
operation can be continued, without tripping, by operating using a frequency
balanced by load current.
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.

3) Inverter overload characteristics
Set to protect the inverter itself. The setting of this parameter cannot be turned to off.
When an inverter overload trip () operates, operation can be improved by lowering stall operating level

Note 2: If an inverter overload occurs with the factor default settings, the inverter is set to lower the carrier
frequency automatically and overload tripping is () controlled. Although noise from the motor
increases when the carrier frequency is reduced, there is no effect on performance. When reducing the
carrier frequency is undesirable, set parameter  = .

☆ In the Easy setting mode, the PRG lamp blinks.
☆ If the EASY key is pressed while the setting dial is being turned, values continue to be incremented or decremented
even if you release your finger from the setting dial.
This feature is handy when setting large values.
Note) Of the available parameters, number value parameters ( etc.) are reflected in actual operation when the
setting dial is turned. Note, however, that the center of the setting dial must be pressed to save values even when
the power is turned off.
Note, also, that item selection parameters ( etc.) are not reflected in actual operation by just turning the
setting dial. To reflect these parameters, press the center of the setting dial.

, 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
(, ).

, Setting acceleration/deceleration time (,) 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.

 (base frequency 1),  (base frequency voltage 1),  (motor rated capacity), 
(motor rated current),  (motor rated rpm)
2) The sensorless vector control exerts its characteristics effectively in frequency areas below the base
frequency (). 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 (=).
E-20
E6581595
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 0.05kW.
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.
When using a combination of several motors, set the V/F constant (=).
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) When a reactor is connected between the inverter and a motor, the motor's generated torque may fall.
Setting auto-tuning may also cause a trip () rendering sensorless vector control unusable.

The dotted line denotes the output frequency obtained by combining the slowdown speed and the

Note: If the operation frequency is set to the lower limit frequency, it will increase from 0Hz when power is
turned on for the first time after the setting, and therefore the output frequency will not rise until the
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  to the lower limit frequency.
Q Adjustment with pulse signals (Operation example 2)
Set parameters as follows to adjust the frequency in steps of one pulse:
,  ≤ Pulse On time
,  = Frequency obtained with each pulse
* The inverter does not respond to any pulses with an ON time shorter than that set with  or

Q 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.
Q 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  (initial up/down frequency).
Q 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  (change of initial up/down
frequency) to 1 (which changes the setting of  when power is turned off).
Keep in mind that the setting of  is changed each time power is turned off.
Q Frequency adjustment range
The frequency can be set from 0.0Hz to  (Maximum frequency). The lower-limit frequency will be
set as soon as the set frequency clearing function (function number 92, 93) is entered from the input
terminal.

Bias adjustment of VI input terminals (f470)
To give leeway, the inverter is factory-adjusted by default so that it will not produce an output until a
certain amount of voltage is applied to the VI input terminal. If you want to reduce the leeway, set f470
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 VI input terminals (f471)
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 VI input terminal 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 f471 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.

Carrier frequency
If ambient temperature exceeds 40°C, reduce current according to table above.
Default setting of PWM carrier frequency is 12kHz, but rated output current of rating label display at 4kHz.
If  is set to  or , however, the carrier frequency will decrease automatically with increase in current
in order to secure the rated current at frequencies of 4 kHz or less.
If =, and current is increased to the automatic reduction level, the  alarm occurs, if current is
increased further  trips.
Random mode is exercised when the motor is operated in a low-frequency range where it produces annoying
acoustic noise.
If the carrier frequency () is set above 8 kHz, the random mode function will not be performed,
because the level of motor magnetic noise is low at high frequencies.

3) Motor speed search at starting
When  is set to , a motor speed search is performed each time operation is started.
This function is useful especially when the motor is not operated by the inverter but it is running because of
external force.
Warning!!
• At restart, it takes about 3 seconds for the inverter to check to see the number of revolutions of the
motor.
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
"=" (Disabled), Do not use the retry function, either.

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  and enters the PID control mode after a lapse of
the specified time.

 : Auto-tuning

 : Motor rated capacity
 : Motor rated current
 : Motor no-load current
 : Motor rated speed
 : Load moment of inertia ratio
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.
1)
Using the torque boost setting macro function () for setting the V/F control mode selection () and
auto-tuning () at the same time
2)
Setting V/F control mode selection () and auto-tuning () independently
3)
Combining the V/F control mode selection () and manual tuning
Caution:
If the settings for V/F control mode selections  are : automatic torque boost control, : vector control, :
energy saving.
Look at the motor's name plate and set the following parameters.
: Base frequency 1 (rated frequency)
: Base frequency voltage 1 (rated voltage)
: Motor rated capacity
: Motor rated current
: Motor rated speed
Set the other motor constants as necessary.
F-37

E6581595
[Selection 1: Setting by parameter setting macro torque boost]
This is the easiest of the available methods. It conducts vector control and auto-tuning at the same time.
Be sure to set the motor for , , , ,  .
Set  to 
(Automatic torque boost + auto-tuning)
Set  to 
(Vector control + auto-tuning).
Set  to 
(Energy-saving + auto-tuning)
See Section 5.4 for details of the setting method.
[Selection 2: Setting vector control and auto-tuning independently]
Set vector control, automatic torque boost, and energy saving and auto-tuning individually.
After setting  (V/F control mode selection), auto-tuning occurs.

Set f400 to 2 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,
“” is displayed on the operation panel.
(3) Tuning is performed when the motor starts for the first time after f400 is set to 2.
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.
F-38
E6581595
[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, set independent motor constants.

Setting procedure Adjust the following parameters:
: Set the compensation gain for the slipping of the motor. A higher slip frequency reduces motor
slipping correspondingly. After setting , set  to adjust in detail. Be careful as
inputting a value larger than necessary causes hunting and other unstable operation.
: 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. Be
careful as setting a value larger than necessary may lead to an increased current causing a trip at
low speeds. (Perform adjustments according to the actual operation.)
: Set the the motor's rated capacity according to the motor's name plate or test report.
: Set the rated current of the motor. For the rated current, see the motor's nameplate or test report.
: Set the ratio of the no-load current of the motor to the rated current. Enter the value in % that is
obtained by dividing the no-load current specified in the motor's test report by the rated current.
Increasing this value increases the excitation current.
: Set the rated rotational speed of the motor. For the rated current, see the motor's nameplate or test
report.
+ Adjustment method for the moment of inertia of the load
6
: Adjusts the excess response speed. A larger value gives a smaller overshoot at the
acceleration/deceleration completion point. In the default settings, the moment of inertia of the load
(including the motor shaft) value is optimally set considering a motor shaft of 1x. When the
moment of inertia of the load is not 1x, set a value that matches that actual moment of inertia of
the load.
 : If the rated capacity of the motor is one size smaller than that of the inverter, lower the thermal
protective level according to the rated current of the motor.
* 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.
Caution:
If a combination of the inverter rating and the motor capacity is different for more than 2 items, vector
control may not operate correctly.

Send data from the host computer.
The inverters receive data from the host computer and the inverter number is checked.
When * is next to the position of an inverter number, it is judged a broadcast. The command is
decoded and processed.
(4) To prevent data conflicts, only inverters where * is overwritten to 0 can reply with data to the host
computer.
(5) As a result, all inverters are operating with the broadcast operation frequency command.
Note: Specify inverter numbers by group for group broadcasts.
(Function only for ASCII mode. For parity mode, see the Communications Function Instruction
Manual.)
(Ex) When *1 is set, inverters 01, 11, 21, 31 to 91 can be broadcast to.
In this case, the inverter specified in 01 can reply.

∗ About programmable controllers and interfaces If controlling the inverter using an open collector output
programmable controller, the following error signals are sent to the inverter. This is a result of differences in the
height of control power supply potential when the inverter remains ON and the programmable controller is turned

as shown above, set  =  (HD: operation hold).
Note 2) If the terminals are ON before turning on the power, terminal input is ignored when the power is
turned ON. (Prevents sudden movements.) After turning the power ON, turn terminal input ON
again.
Note 3) When HD is OFF, F and R are ignored even when ON. R does not operate even if it's ON when
HD is ON. Likewise in this state, F does not operate even if it's ON. Turn F and R OFF and then
turn them ON.

Note 4) During 3 wire operation, sending the jog run mode command stops operation.
Note 5) Be aware that DC braking continues even if a startup signal is input during DC braking.
Note 6) Only F and R maintain HD (operation hold). When using F or R in combination with other
functions, be aware that the other functions do not hold. For example, when F and SS1 are
assigned, F holds, but SS1 does not.

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,
made 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
The CE mark must be put on every final product that includes an inverter(s) and a motor(s). In the VF-nC3 series
of inverters, the single-phase 200 V class is equipped with an EMI filter and complies with the EMC directive if
wiring is carried out correctly.
„ EMC directive
2004/108/EC
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.

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.
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 input and output wires apart from each other.
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 and cabinet (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.
Consult us about the three-phase 240 V and single-phase 120 V classes.

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.

E6581595
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) Connect earth wiring to the earth terminal on the EMC plate. 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. (See chapter 10.)
9.2
Compliance with UL Standard and CSA Standard
The VF-nC3 models, that conform to the UL Standard and CSA Standard have the UL/CSA mark on the
nameplate.
9.2.1
Compliance with Installation
A UL certificate was granted on the assumption that the inverter would be installed in a cabinet. Therefore, install
the inverter in a cabinet and if necessary, take measures to maintain the ambient temperature (temperature in the
cabinet) within the specified temperature range. (See section 1.4.4)
9
9.2.2
Compliance with Connection
Use the UL conformed cables (Rating 75 °C or more, Use the copper conductors only.) to the main circuit
terminals (3-phase models: R/L1, S/L2, T/L3, single-phase models: R/L1, S/L2/N).
For instruction in the United States, Integral solid state short circuit protection does not provide branch circuit
protection. Branch circuit protection must be provided in accordance with the National Electrical Code and any
additional local codes.
For instruction in the Canada, Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the Canadian Electrical Code and any additional
local codes.
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: Models made by Toshiba Industrial Products Sales Corporation are shown.
Note 2: Be sure to attach a surge killer to the exciting coil of the relay and the magnetic contactor.
Note 3: When using the auxiliary contacts 2a of the magnetic contactor MC for the control circuit, connect the
contacts 2a in parallel to increase reliability.
Note 4: Select an MCCB with a current breaking rating appropriate to the capacity of the power supply, because
short-circuit currents vary greatly depending on the capacity of the power supply and the condition of the
wiring system. The MCCB, MC, THR and ELCB in this table were selected, on the assumption that a
power supply with a normal capacity would be used.
J-2
E6581595
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.
When using an optional brake module, install a magnetic contactor (MC) or non-fuse circuit breaker with a power
cutoff device on the primary power supply of the inverter, so that the power circuit opens when the failure
detection relay (FL) in the inverter or the externally installed overload relay is actuated.
Q 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)
(2)
(3)
(4)
If the motor overload relay is tripped
If the protective detector (FL) built into the inverter is activated
In the event of a power failure (for prevention of auto-restart)
If the resistor protective relay is tripped when a braking resistor and braking module (option) are used
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).
J-3
E6581595
„ 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-nC3 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 () 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.
When using the VF-nC3 inverter to operate a constant-torque motor, such as the Toshiba VF motor, adjust
the protection characteristic of the electronic thermal protection unit (0m) 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.

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 inverter trip hold selection  for details.
(2) By means of an external signal (Short circuit across RES and CC on control terminal block → Open): The
reset function must be assigned to the input terminal block.
(3) By panel keypad operation
(4) By inputting a trip clear signal from communication
(Refer to communication manual for details.)
To reset the inverter by panel keypad operation, follow these steps.
1.
Press the STOP key and make sure that  is displayed.
2. Pressing the STOP key again will reset the inverter if the cause of the trip has already been eliminated.
,
When any overload function [: inverter overload, : motor overload] is active, the inverter
cannot be reset by inputting a reset signal from an external device or by operation panel operation
before the virtual cooling time has passed.
Virtual cooling time ...  : about 30 seconds after the occurrence of a trip
 : about 120 seconds after a occurrence of a trip
,
,
In case of a trip due to overheat (), the inverter checks the temperature within. Wait until the
temperature in the inverter falls sufficiently before resetting the inverter.
The inverter cannot be reset while the emergency stop signal is being input from the terminal.
[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
Warning
Instruction
• 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 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (400V 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.
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.

Warning
Instruction
Prohibited
•Before inspection, perform the following steps.
(1) Shut off all input power to the inverter.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (400V 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 and bodily injury. To replace parts, call the local sales
agency.
Q Check items
14
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.
5. 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
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.
N-2
E6581595
(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.
Q 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 for cooling heat-generating parts has a service life of about ten years. 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. Since the smoothing capacitor is mounted on a printed circuit board, it
must be replaced together with the circuit board.
<Criteria for appearance check>
• Absence of liquid leak
• Safety valve in the depressed position
• Measurement of electrostatic capacitance and insulation resistance
Note: Checking the life alarm function is useful for roughly determining the parts replacement time. To
ensure customer safety, you should never replace parts on your own. (It is also possible to monitor
the part replacement alarm and output a signal.)
N-3
14
E6581595
Q 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.
Also, make use of the life alarm function.

Note 2: Figures are for when the inverter output current is 80% of the rated current of the inverter.
Note 3: The life of parts varies greatly depending on the operating environment.
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.
14
Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder.
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 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
Caution
Instruction
• 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.
