<1> The motor capacity (HP) refers to an NEC 4-pole motor. The rated output current of the drive 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
connections, and power supply impedance.
<3> Rated input capacity is calculated with a power line voltage of 480 V × 1.1.
<4> The rated output current of the drive should be equal to or greater than the motor rated current.
<5> Carrier frequency is set to 4 kHz. Current derating is required to raise the carrier frequency.
<6> If one of the following specifications are needed, the maximum output voltage = [input voltage] × 0.87:
Harmonic current distortion of 5% or less
Harmonic suppression guidelines compliance
Input power factor of 0.98 or higher.
