<1> The motor capacity (HP) refers to an NEC Table 430.250 208 V 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
connections, and power supply impedance.
<3> Carrier frequency is set to 5 kHz. Current derating is required to raise the carrier frequency.
