*1 The maximum applicable motor output complies with 380 V motor ratings as specified in Annex G of IEC 60947-4-1. The rated
output current of the drive output amps must be equal to or more than the motor rated current.
*2 The maximum applicable motor output complies with 460 V motor ratings as specified in NEC Table 430.250. The rated output
current of the drive output amps must be equal to or more than the motor rated current.
*3 Assumes the value at the rated output current. The input current rating changes when the power supply transformer, input reactor,
wiring connections, or power supply impedance change.
*4 The rated output capacity is calculated with a rated output voltage of 380 V.
*5 The rated output capacity is calculated with a rated output voltage of 460 V.
