Notes:
1) A 4-pole standard motor is assumed as a nominal
applied motor.
2) Inverter output capacity (kVA) at 220V.
3) When a momentary power failure occurs, while rated
voltage is applied 85% of load of nominal motor is
given.
4) When an optional power-factor correcting DC reactor is
used.
5) Average braking torque where an unloaded motor
decelerates and stops from 60Hz operation. (Varies
according to the motor efficiency)
6) The specification is calculated on assumption that the
inverter is connected to a 500 kVA-equivalent power
transformer.
