A.3 Three-Phase 400 V Class Drives A.3 Three-Phase 400 V Class Drives Table A.3 Power Ratings The motor capacity (kW) refers to a Yaskawa 4-pole motor. The rated output current of the drive output amps should be equal to or greater than the motor rated current. Input current rating varies depending on the power supply transformer, input reactor, wiring conditions, and power supply impedance. Rated motor capacity is calculated with a rated output voltage of 440 V. Carrier frequency is set to Swing PWM. Current derating is required in order to raise the carrier frequency. Carrier frequency is set to 8 kHz. Current derating is required in order to raise the carrier frequency. Note:
Differences between Heavy Duty (HD) ratings and Normal Duty (ND) ratings for the drive include rated input and output current, overload capacity, carrier frequency and current limit. Set parameter C6-01 to “0” (default) for HD or “1” for ND.
