Safety precautions
Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or
maintenance and inspection. Ensure you have sound knowledge of the device and familiarize yourself with
all safety information and precautions before proceeding to operate the inverter.
Safety precautions are classified into the following two categories in this manual.
Failure to heed the information indicated by this symbol may lead to
dangerous conditions, possibly resulting in death or serious bodily injuries.
Failure to heed the information indicated by this symbol may lead to
dangerous conditions, possibly resulting in minor or light bodily injuries
and/or substantial property damage.
Failure to heed the information contained under the CAUTION title can also result in serious consequences.
These safety precautions are of utmost importance and must be observed at all times.
Application
• The FRENIC-VG is designed to drive a three-phase induction motor. Do not use it for single-phase motors or for other
purposes.
Fire or an accident could occur.
• The FRENIC-VG may not be used for a life-support system or other purposes directly related to the human safety.
• Though the FRENIC-VG is manufactured under strict quality control, install safety devices for applications where
serious accidents or property damages are foreseen in relation to the failure of it.
An accident could occur.
Installation
• Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• Inverters with a capacity of 30 kW or above, whose protective structure is IP00, involve a possibility that a human body
may touch the live conductors of the main circuit terminal block. Inverters to which an optional DC reactor is connected
also involve the same. Install such inverters in an inaccessible place.
Otherwise, electric shock or injuries could occur.
• Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter or from
accumulating on the heat sink.
• When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or an accident might result.
• Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.

xi
Wiring
• If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is installed in the upstream
power supply line in order to avoid the entire power supply system's shutdown undesirable to factory operation, install
a residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) individually to inverters to
break the individual inverter power supply lines only.
Otherwise, a fire could occur.
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) (with overcurrent protection)
in the path of each pair of power lines to inverters. Use the recommended devices within the recommended current
capacity.
• Use wires in the specified size.
• Tighten terminals with specified torque.
Otherwise, a fire could occur.
• When there is more than one combination of an inverter and motor, do not use a multicore cable for the purpose of
handling their wirings together.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Be sure to connect an optional DC reactor (DCR) when the capacity of the power supply transformer exceeds 500 kVA
and is 10 times or more the inverter rated capacity.
Otherwise, a fire could occur.
• Ground the inverter in compliance with the national or local electric code.
• Be sure to ground the inverter's grounding terminals G.
Otherwise, an electric shock or a fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, an electric shock could occur.
• Be sure to perform wiring after installing the inverter unit.
Otherwise, an electric shock or injuries could occur.
• Ensure that the number of input phases and the rated voltage of the product match the number of phases and the voltage
of the AC power supply to which the product is to be connected.
Otherwise, a fire or an accident could occur.
• Do not connect the power supply wires to output terminals (U, V, and W).
• When connecting a DC braking resistor (DBR), never connect it to terminals other than terminals P(+) and DB.
Doing so could cause fire or an accident.
• In general, sheaths of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced
insulation is not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main
circuit, the insulation of the sheath might break down, which would expose the signal wire to a high voltage of the main
circuit. Make sure that the control signal wires will not come into contact with live conductors of the main circuit.
Doing so could cause an accident or an electric shock.
• Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and wait at
least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a
capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure,
using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has
dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
• The inverter, motor and wiring generate electric noise. Be careful about malfunction of the nearby sensors and devices.
To prevent them from malfunctioning, implement noise control measures.
Otherwise an accident could occur.

xii
Operation
• Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter power is ON.
Otherwise, an electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the auto-reset function has been selected, the inverter may automatically restart and drive the motor depending on the
cause of tripping. Design the machinery or equipment so that human safety is ensured at the time of restarting.
Otherwise, an accident could occur.
• If the stall prevention function (torque limiter) has been selected, the inverter may operate with
acceleration/deceleration or speed different from the commanded ones. Design the machine so that safety is ensured
even in such cases.
• The key on the keypad is effective only when the keypad operation is enabled with function code F02 (= 0, 2 or 3).
When the keypad operation is disabled, prepare an emergency stop switch separately for safe operations. Switching the
run command source from keypad (local) to external equipment (remote) by turning ON the "Enable communications
link" command LE disables the key.
To enable the key for an emergency stop, select the STOP key priority with function code H96 (= 1 or 3).
• If any of the protective functions have been activated, first remove the cause. Then, after checking that the all run
commands are set to OFF, release the alarm. If the alarm is released while any run commands are set to ON, the inverter
may supply the power to the motor, running the motor.
Otherwise, an accident could occur.
• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3 to 5), then the inverter
automatically restarts running the motor when the power is recovered.
Design the machinery or equipment so that human safety is ensured after restarting.
• If the user configures the function codes wrongly without completely understanding this Instruction Manual and the
FRENIC-VG User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
An accident or injuries could occur.
• Even if the inverter has interrupted power to the motor, if the voltage is applied to the main circuit input terminals L1/R,
L2/S and L3/T, voltage may be output to inverter output terminals U, V, and W.
• Even if the run command is set to OFF, voltage is output to inverter output terminals U, V, and W if the servo-lock
command is ON.
• Even if the motor is stopped due to DC braking or preliminary excitation, voltage is output to inverter output terminals
U, V, and W.
An electric shock may occur.
• The inverter can easily accept high-speed operation. When changing the speed setting, carefully check the
specifications of motors or equipment beforehand.
Otherwise, injuries could occur.
• Do not touch the heat sink and braking resistor because they become very hot.
Doing so could cause burns.
• The DC brake function of the inverter does not provide any holding mechanism.
Injuries could occur.
• Ensure safety before modifying the function code settings.
Run commands (e.g., "Run forward" FWD), stop commands (e.g., "Coast to a stop" BX), and speed change commands
can be assigned to digital input terminals. Depending upon the assignment states of those terminals, modifying the
function code setting may cause a sudden motor start or an abrupt change in speed.
• When the inverter is controlled with the digital input signals, switching run or speed command sources with the related
terminal commands (e.g., SS1, SS2, SS4, SS8, N2/N1, KP/PID, IVS, and LE) may cause a sudden motor start or an
abrupt change in speed.
An accident or injuries could occur.

xiii
Maintenance and inspection, and parts replacement
• Before proceeding to the maintenance/inspection jobs, turn OFF the power and wait at least five minutes for
inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or
above. Make sure that the LED monitor and charging lamp are turned OFF. Further, make sure, using a multimeter or a
similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25
VDC or below).
Otherwise, an electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
Otherwise, an electric shock or injuries could occur.
• Never modify the inverter.
Doing so could cause an electric shock or injuries.
Disposal
• Treat the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.
Speed control mode
• If the control parameters of the automatic speed regulator (ASR) are not appropriately configured under speed control,
even turning the run command OFF may not decelerate the motor due to hunting caused by high gain setting.
Accordingly, the inverter may not reach the stop conditions so that it may continue running.
Even if the inverter starts deceleration, the detected speed deviates from the zero speed area before the zero speed
control duration (F39) elapses due to hunting caused by high response in low speed operation. Accordingly, the inverter
will not reach the stop conditions so that it enters the deceleration mode again and continues running.
If any of the above problems occurs, adjust the ASR control parameters to appropriate values and use the speed
mismatch alarm function in order to alarm-trip the inverter, switch the control parameters by speed, or judge the
detection of a stop speed by commanded values when the actual speed deviates from the commanded one.
An accident or injuries could occur.
Torque control mode
• When the motor is rotated by load-side torque exceeding the torque command under torque control, turning the run
command OFF may not bring the stop conditions so that the inverter may continue running.
To shut down the inverter output, switch from torque control to speed control and apply a decelerate-to-stop or
coast-to-stop command.
An accident or injuries could occur.
