*1 Fuji 4-pole standard motor
*2 Rated capacity is calculated assuming the rated output voltage as 440 V (460 V).
*3 Output voltage cannot exceed the power supply voltage.
*4 Setting the carrier frequency (F26) to the following value or above requires current derating.
ND spec. of all types : 4 kHz
If the ambient temperature is 40°C (104°F) or above, derating of 2%/°C (2%/1.8°F) relative to the rated
current given in this manual is required. For details, refer to Chapter 10 “10.4.2 Guideline for selecting
inverter drive mode and capacity.”

= (%) unbalance Voltage
(IEC 61800-3)
If the unbalance ratio is 2% to 3%, use an optional AC reactor (ACR).
*7 This specification is an estimated value to be applied when the power supply capacity is 500 kVA (Inverter
capacity × 10 when the capacity exceeds 50 kVA) and the power supply with %X = 5% is connected.
*8 This specification applies when a DC reactor (DCR) is used.
*9 Average braking torque for the motor running alone. It depends on the efficiency of the motor.
