Input
<1> The motor capacity (HP) refers to a NEC rated 4-pole motor. The rated output current of the drive output amps should be equal to or greater
than the motor current. Select the appropriate capacity drive if operating the motor continuously above motor nameplate current.
<2> Assumes operation at the rated output current. Input current rating varies depending on the power supply transformer, input reactor, wiring
conditions, and power supply impedance. This input current rating is the 3-Phase total input current rating. For the 6-Phase input current rating
see Table C.1.
<3> Rated motor capacity is calculated with a rated output voltage of 440 V.
<4> Carrier frequency is set to 2 kHz. Current derating is required in order to raise the carrier frequency.
<5> Carrier frequency can be increased to 5 kHz while keeping this current derating. Higher carrier frequency settings require derating.
