Notes on the application
Motors
1.4.1
When the VF-nC1 and the motor are used in conjunction, pay attention to the following items.
1
Warning
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 three-phase induction motor not rotate correctly, but it
may causes serious accidents through overheating and fire.
Mandatory
Comparisons with commercial power operation.
The VF-nC1 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 (QNO)".
Adjusting the overload protection level
The VF-nC1 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.
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.
•
•
Combined with couplings between load devices and motors with high backlash
Combined with loads that have sharp fluctuations in rotation such as piston movements
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.

E6581090
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
1
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.

Circuit configuration 1
Circuit configuration 2
In circuit configuration 1, the brake is turned on and off through MC2 and MC3. If the circuit is
configured 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
FM/OUT 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 5-10 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 interupting 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.
What to do about leak current
Warning
1.4.3
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) Leakage current from the inverter main unit
As compared with other types of inverters, a large amount of current leaks from your inverter
when it is used in delta connection (with one phase grounded). Take this into consideration when
selecting an earth leakage breaker.

(2) Effects of leakage 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, 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 Hꢀꢁꢁ.
2. Use high frequency remedial products 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
①Thermal 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 leak current will increase in proportion to the motor
rating.
Remedies:
1. Use the electronic thermal built into the inverter.
The setting of the electronic thermal is done using parameter QNO & VJT.
2. Reduce the inverter's PWM carrier frequency. However, that will increase the motor's
magnetic noise. Use parameter Hꢀꢁꢁ 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.

W/T3
Thermal relay
②CT 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 leak current will increase in
proportion to the motor's rated current.
Remedies:
1. Use a multi-function programmable output terminal for the inverter’s control circuit.
A current can be put out via the FM/OUT terminal.
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.
1
Prohibited
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
•
•
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.
Mandatory
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.

■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 ( ).
•
•
•
•
•
Install surge suppressor on any magnetic contactor and relay coils used around the inverter.
Install noise filters if necessary.

■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 exceed 40°C, allow a space of 5 cm
or more between inverters and detach the caution label on the top surface of each inverter.
Ensure a space of at least 20 cm 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.

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.
Turn power on only after attaching the front cover or closing door if enclosed in a
cabinet.
Prohibited
Mandatory
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.
①Shut off all input power.
②Wait at least 15 minutes and check to make sure that the charge lamp is no
longer lit.
③Use 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/C) 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.
Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire when a

This could cause a fire.
Prohibited
■Preventing radio noise
2
To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's
power terminals (R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).
■Control and main power supply
The control power supply and the main circuit power supply for the VF-nC1 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]).
Use as large and short a ground wire as possible and wire it as close as possible to the inverter.
See the table in 10.1 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.

Standard connections
Danger
•
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.
Prohibited
•
•
Do not connect resistors to DC terminals (across PA/+-PC/- or across PO-PC/-).
It could cause a fire.
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.
•
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.

■Sink logic (negative common)/source logic (positive common)
⋅⋅⋅ Logic switching of input output terminals
Current flowing out turns control input terminals on. These are called sink logic terminals. (For all
models except models with a built-in noise filter, control input terminals are factory-set to sink
logic.) The general used method in Europe is source logic in which current flowing into the input
terminal turns it on.

■Switching the input terminal logic between sink and source
Input terminals of the VF-nC1 inverter can be switched between sink logic and source logic, using
the Hꢀꢃꢄ parameter.
When switching between sink logic and source logic, do it before connecting cables to inverter’s
control circuit terminals. When the confirmation message Gꢀꢁ or Gꢀꢂ is displayed after
switching between sink logic and source logic, using the Hꢀꢃꢄ parameter, reset the inverter,
using the operation panel, by turning the power off, or by inputting a reset signal from an external
control device.
■Switching the VI/S3 terminal between logic input and analog input
The VI/S3 terminal of the VF-nC1 inverter can be switched between contact input and analog
input by changing a parameter setting. When switching between contact input and analog input,
do it before connecting cables to inverter’s control circuit terminals (Hꢀꢁꢂ).
If switching between contact input and analog input is done after cable connection, the inverter
and/or the external device connected might be damaged. Before turning on the inverter, make
sure all cables are connected correctly to the control terminals.
When using the VI/S3 terminal as an contact input terminal (sink logic), be sure to insert a
resistor* between the P15 and VI/S3 terminals. (Recommended resistance: 4.7kΩ-1/4W).
■Switching the FM/OUT terminal between meter output (PWM output) and open
collector output
The FM/OUT terminal of the VF-nC1 inverter can be switched between meter output (PWM
output) and open collector output.
When switching between meter output (PWM output) and open collector output, do it before
connecting an external device to the inverter. After switching from meter output (PWM output) to
open collector output, and vice versa, check using the HOUN parameter to be sure that the
desired function is assigned to the FM/OUT terminal, and then turn the power off. After the
completion of cable connection, turn the power back on. If switching between meter output and
open collector output is done after cable connection, the inverter might be damaged.

3. Simple operation
Danger
•
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.
Prohibited
•
•
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.
3
•
•
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.
Mandatory
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. These devices 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.

How to set a setup parameter
Setup parameter
After you set the basic parameter V[R to ꢉ (Initialize to default setting) or the first power, the
inverter will be in setup parameter mode. When the inverter is in this mode, you need to set a
setup parameter, as described below, to make the inverter ready for operation.
Set the setup parameter according to the logic for control input signals used and the base frequency
of the motor connected. (If you are not sure which setup parameter should be selected among
Pꢁꢂ, Rꢁꢂ and Pꢃꢂ and what values should be specified, consult your reseller.)
Each setup parameter automatically sets all parameters relating to the logic for control input signals
used and the base frequency of the motor connected.

This parameter setting is needed only for the VFNC1 (S)-□□□□P□-W.
Follow these steps to change the setup parameter [Example: Changing from Pꢁꢂ to Pꢀꢁ: sink

How to set (use) special parameters
(1) Setting a parameter, using the wizard function (CWH)
Wizard function (CWH):
The wizard function refers to the special function of calling up only functions necessary to set up
the inverter in response to the user’s needs. When a purpose-specific wizard is selected, a group
of parameters needed for the specified application (function) is formed and the inverter is switched
automatically to the mode of setting the group of parameters selected. You can set up the inverter
easily by simply setting the parameters in the group one after another. The wizard function (CWH)
provides four purpose-specific wizards.

Meter setting and adjustment
HOUN : FM/OUT terminal functions selection
HO
: Meter adjustment
• Function
The FM/OUT terminal can be switched between meter output (PWM output) and open
collector. When connecting a meter to the FM/OUT terminal, set the HOUN parameter to a
number other than -1 (open collector output) and connect the meter between FM/OUT
(positive side) and CC (negative side).
If you want to connect a meter to the inverter, choose a full-scale 0~1mAdc ammeter or a
full-scale 0~7.5Vdc-1mA voltmeter.
The meter output of VFNC1 may have some errors because of PWM waveform.
Especially if the meter output is near 0, the errors may be increased.

■Adjusting the meter in inverter stop state
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.
If HOUN is set to ꢃ “for adjustment (current fixed at 100%)”, the inverter puts out signals via the
FM / OUT terminal, assuming that 100% of current (inverter’s rated current) is flowing. In this
state, adjust the meter with the HO (Meter adjustment) parameter. (HOUN: 4, 5, 6, 7 can be
adjusted in the same way.)
After meter adjustment is ended, set HOUN to ꢁ (output current).

Torque boost 1 (%)
Depends on the model.
The default torque characteristic is set based on the torque characteristic of World Energy series 4P
motors manufactured by Toshiba Industrial Machinery.
When using the inverter with a VF motor or a motor with 6 or more poles, set the torque boost
parameter at 80% or so of the default setting.
When the inverter is used with a special motor with a particular V/F ratio, it requires adjustments.
Excessively boosting torque could results in an overcurrent trip. To avoid this, do not increase torque
by more than 1.2 times the default torque.
2) Correcting the error in rotational speed due to the slippage of the motor
Setting of V/F control mode selection RV to ꢃ (Vector control)
Setting this parameter to 3 causes the inverter to monitor the load currents and automatically
correct the error in speed caused by the slippage of the motor. Slip correction gain is adjusted to
correct the error in speed caused by the slippage of the motor.

1) Setting the electronic thermal protection characteristics selection
QNO and
motor electronic thermal protection level 1 VJT
The electronic thermal protection characteristics selection QNO is used to enable or disable the
motor overload trip function (QNꢂ) and the overload stall function.
While the inverter overload trip (QNꢁ) will be in constant detect operation, the motor overload trip
(QNꢂ) can be selected using the parameter QNO.
Explanation of terms
Overload stall : When the inverter detects an overload, this function automatically lowers the
output frequency before the motor overload trip QNꢂ 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.

A VF motor (motor for use with an inverter) can be used in lower frequency ranges than the general-
purpose motor, but if that frequency is extremely low, the effects of cooling on the motor will deteriorate.
■Setting the motor electronic thermal protection level 1 VJT
If the capacity of the motor being used is smaller than the capacity of the inverter, or the rated
current of the motor is smaller than the rated current of the inverter, adjust the electronic thermal
protection level 1 VJT so that it fits the motor's rated current.

This signal can be used as an electromagnetic brake excitation/release signal.
When using
a
low speed signal for reversing the direction of rotation of the motor, set the
Hꢀꢁꢁ parameter (low speed signal output frequency) above 1 kHz.
★The low speed signal output frequency function is assigned by default to the FM/OUT
terminal.
★Before using the FM/OUT terminal, you need to make a selection between meter (PWM)
output and open collector output.
To use the FM/OUT terminal as an open collector output terminal, set HOUN to -1 (open
collector output).
★Signals can be sent to the relay output terminals FLA, FLB and FLC by changing a
parameter setting.

• Function
These parameters are used to specify a function for each individual input terminal. With these
parameters allowing selection from among 45 functions for each input terminal, you can design
a system with great flexibility. (For Hꢀꢀꢆ (input terminal selection 5), you can make a
selection from among 13 functions.)
*1 Using the Hꢀꢁꢄ parameter, you can select a function between analog input (frequency
command input) and contact input for the VI/S3 terminal. The VI/S3 terminal is set by default
as a voltage signal input terminal. When using the VI/S3 terminal as a contact input terminal,
you need to set Hꢀꢁꢄ to 2 (contact input enabled), and then to specify a contact input
function for it, using Hꢀꢀꢆ, because it is set by default as a voltage signal input terminal.
Note: Do not set Hꢀꢁꢄ parameter if VI/S3 terminal is not used as contact input.

Interface between inverter and programmable controller
When an open collector output type programmable controller is being used for operation control,
turning off the programmable controller with the inverter left ON causes a wrong signal to flow
into the inverter, as shown in the figure below, because of a difference in control power potential.
To avoid this, be sure to interlock the inverter and the programmable controller so that the
programmable controller cannot be turned off when the inverter is on.

6.2.4
Jog run
• Function
The VF-nC1 inverter is capable of jog operation if its input terminal selection function is so set.
Jog run refers to jogging or inching
a
motor. Input of
a
jog run signal causes the VF-nC1
inverter to produce a jog run signal (fixed at 5Hz) for 0.1 seconds (fixed), regardless of the
specified acceleration time. Cutting off a jog run signal causes the motor to coast to a stop.
■The motor continues to run in jog mode as long as both the jog run signal and the operation signal
are put out. To enable the jog run function, you need to assign the jog run function (4) to an
unassigned input terminal.
For the VF-nC1 inverter, all settings for jog run are fixed, as shown below.

The jog run terminals (S1-CC) are enabled when the operation frequency is below 5Hz. They
do not function when the operation frequency is higher than the jog run frequency (5Hz).
The motor continues to run in jog mode while the jog run terminals (S1-CC) are electrically
connected.
Jog run has priority, and it continues even if any other operation command is entered during
operation.
Note: During jog run, the VF-nC1 inverter may produce an Low-speed detection signal (LOW) signal
but not Designated frequency reach signal (RCH) signal, and therefore PI control is not
performed.

PWM carrier frequency
Hꢂꢁꢁ : PWM carrier frequency
•
Function
1) This parameter is used for changing the carrier frequency in order to change the tone of the
magnetic noise produced by the motor. This parameter is also effective in preventing the
motor from resonating with its load machine or fan cover.
2) In addition, this parameter is used to reduce the electromagnetic noise produced by the
inverter. To reduce the electromagnetic noise, decrease the carrier frequency.
Note: This reduces the electromagnetic noise but increases the magnetic noise from the motor.
3) If the PWM carrier frequency is set above 4kHz, it may fall automatically during acceleration
or under certain circumstances where an overcurrent flows.

Function
Although the rated current at 4kHz is shown on the rating plate, the PWM carrier frequency is
set to 12kHz by default.
Note: In order to protect the inverter, PWM carrier frequency may fall automatically depending on
the circumstances even if it is under the derating in accordance with above table.
If using foot-mounted type noise reduction filter EMFAS2011Z or EMFA2006Z with VF-nC1, it
is necessary to decrease 5% more of rated current in above table.

more time than usual.
•
Use this function when operating a system with one inverter connected with one motor.
This function may not be performed properly in a system with one inverter connected
with multiple motors.
Application to a crane or hoist
The crane or hoist might allow the load to move downward during the time elapsed before
the motor starts after receiving an operation starting command. When applying the
inverter to such a lifting gear, set the auto-restart control selection parameter to 0
(disabled) and avoid using the retry function.

9. Taking measures to satisfy the CE / UL / CSA
9.1
Compliance with CE Marking
9.1.1
Abstract
In Europe, EMC directive is enforced starting 1st Jan. of 1996, and Low Voltage Directive starting 1st
Jan. of 1997. The display of CE mark that demonstrates that products imported to European Union
conform to these directives is required. Inverter itself cannot function alone, but is de-signed as a
component in order to control machines or equipment which includes that inverter installed in a
cubicle. Therefore the conformance to EMC directive is not required on inverter it-self. But since the
object of the Low Voltage directive is equipment that is designed to be used with rated voltage of 50
to 1,000 VAC or 75 to 1,500 VDC, CE should be marked on inverter as to the Low Voltage directive.
But CE has to be marked on the final product installing inverters, that conforms to the EMC directive
and the Low Voltage directive. And the product also may conform to Machine directive. The user
that makes the final products have to take the responsibility for Marking of CE. For that reason, we
recommend installation for Low Voltage directive and measurement for EMC directive, so that the
products including our inverter should conform to the EMC and Low Voltage directive.
TOSHIBA carried out Approval testing and confirmation testing on representative models under the
circumstances based on installation and measurement so that our products should conform to each
directive. But we cannot confirm the conformance of the user’s products to the EMC directive. Since
EMC environment changes according to the construction of the cubicle and the relation of other
installed electric equipment and the condition of wiring and installation, please confirm the
conformance to the EMC directive for the final products on your side.

9.1.2
EMC directive
An inverter itself is not an object of CE marking.
A machine which consists of an inverter and a motor is an object of CE marking.
The EMC directive includes the emission section and the immunity section. VF-NC1 can conform to
EMC directive by means of installing the recommended EMI noise filter to the input side, and wiring
properly.

Compliance with EMC directive
9.1.3.1 The model, noise filter inside
(1) Single-phase 200V class : VFNC1S-2002PL to 2022PL
The above mentioned models install EMI noise filter inside. So the conducted and radiated
noise can be reduced, optional EMI noise filters are not needed.
(The additional noise filter should be installed, when more effective reduction is required.)
(2) The main cables such as input to the EMI filter and output of the inverter and the signal cables
should be shielded, then cable length should be wired as short as possible. The main input
cable should be separated from the main output cable, and cables for control signal also should
be separated from main cables, not wiring parallel and not bundling, cross the wires where
necessary.
(3) Install EMI filter and inverter on the same metal back plate in an inverter panel. The metal back
plate or the cubicle must be grounded absolutely, by using short thick wires, separated from the
main cables.
(4) Shielded cables should be grounded on the metal back plate in order to reduce the radiated
noise from the other cables. It is an effective measure that shielded cables are grounded close
to the inverter or/and operation panel or/and EMI filter(less than 10cm).
(5) Installation of the zero-phase and/or the ferrite core can also effectively reduce the radiated
noise further.(Input or/and output of inverter)

This subsection explains what measures must be taken to satisfy the EMC directive.
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.

Installation of a magnetic contactor
If using the inverter without installing a magnetic contactor (MC) in the primary circuit, use an MCCB
(with a power cutoff device) to open the primary circuit when the inverter protective circuit is activated.
■Magnetic contactor in the primary circuit
A magnetic contactor, if installed in the power supply circuit of the inverter, cuts off the power supply
to the circuit and prevents the inverter from restarting, in the event of a power failure, a trip of the
overload relay (thermal relay) or the activation of the inverter protective circuit.
In addition, if the FL contact of the failure detection relay in the VF-nC1 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.

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) The VF-nC1 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
2) When using the VF-nC1 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.
3) It is recommended to use a motor with a thermal relay embedded in the motor coil to give
sufficient protection to the motor, especially when it runs in a low-speed range.

Note)
1. Capacity is calculated at 220V for the 200V models.
2. Indicates rated output current setting when the PWM carrier frequency (parameter Hꢀꢁꢁ) is 4kHz or
less.
If the PWM carrier frequency setting is fixed above 4 kHz, the rated current needs to be reduced. If the
PWM carrier frequency is set above 4 kHz, it could fall automatically if an over-current flaws during
acceleration or for any other reason, depending on the amount of current that flows.
The default setting of the PWN carrier frequency is 12kHz.
3. Maximum output voltage is the same as the input voltage.
With regard to 100V models, the output voltage may decrease about 10 to 20 % if motor load is applied.
When operating VFNC1 in conjunction with general purpose motor (200V), it is necessary to reduce the
motor load.
4. ±10% when the inverter is used continuously (load of 100%).

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 6.1 4.2 (inverter trip retention selection Hꢅꢂꢃ) for details.
(2) By means of an external signal [Short-circuiting of control terminals RST and CC
(Assignment of functions to input terminals is necessary)]
(3) By operation panel operation
(4) By inputting a trip clear signal from a remote input device
(Refer to the Communications Equipment User’s Manual for details.)
To reset the inverter by operation panel operation, follow these steps.
1. Press the STOP key and make sure that ENT 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 [QNꢀ : inverter overload, QNꢃ : 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 ････ QNꢀ : about 30 seconds after the occurrence of a trip
QNꢃ : about 120 seconds after the occurrence of a trip
[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
☆If the inverter trips because of overheating (QJ), do not reset the inverter immediately but wait
until the temperature in the inverter comes down, because its internal temperature is monitored.

14. Inspection and maintenance
Danger
•
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.
Mandatory
•
Before inspection, perform the following steps.
①Shut off all input power to the inverter.
②Wait for at least 15 minutes and check that the charge lamp is no longer lit.
③Use 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.
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.

14.2
Periodical inspection
Make a periodical inspection at intervals of 3 or 6 months depending on the operating conditions.
Danger
• Before inspection, perform the following steps.
①Shut off all input power to the inverter.
②Wait for at least 15 minutes and check that the charge lamp is no longer lit.
③Use 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.
Mandatory
Prohibited
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.
■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.
14
(Note) Before an insulation test, always disconnect all cables from the main circuit terminal board
and test the inverter separately from other equipment.

■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.
No parts of the inverter except the cooling fan can be replaced individually, and the whole inverter
needs to be replaced if a significant defect is found in it.
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.

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.
Keeping the inverter in storage
Take the following precautions when keeping the inverter in storage temporarily or for a long period
of time.
1. Store the inverter in a well-ventilated place away from heat, damp, dust and metal powder.
2. If the printed circuit board in your inverter has an anti-static cover (black cover), do not leave it
detached from the circuit board during storage, though the cover must be detached before
turning on the inverter.
3. If no power is supplied to the inverter for a long time, the performance of its 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.
