Here, a motor rotation frequency/phase detection circuit of each inverter control circuit is set up on a closer side to the motor than the breakers, then frequency and phase of a terminal voltage at the motor are detected and inputted into failure-time input frequency/phase setting circuits regardless of close/open of each breaker. This feature allows computation by the failure-time input frequency/phase setting circuits to be carried out at all times, thereby making it possible to shorten a computation time needed for computing inverter-apparatus start frequency/phase.
