<1> 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.
<2> Input current rating varies depending on the power supply transformer, input reactor, wiring conditions, and power supply impedance.
<3> Rated motor capacity is calculated with a rated output voltage of 440 V.
<4> Carrier frequency is set to Swing PWM. Current derating is required in order to raise the carrier frequency.
<5> 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.
