The rated output current of the drive output amps should be equal to orgreater 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, wiringconnections, and power supply impedance.<3> Carrier frequency is set to 5 kHz. Current derating is required to raise the carrier frequency.A.1 Power RatingsYASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual 301A Specifications
