To provide stable limitation characteristics from a low-frequency range to a rated frequency range of the output frequency, without being affected by the difference in the torque current detector or the torque computing unit, when regenerative power is limited by a voltage-type inverter device of the type that performs only capacitor regeneration.

A changeover switch is provided that changes over frequency command input into a pulse computing unit, that controls the PWM control of an inverter from a given command value to the output of a frequency adjusted. This changeover switch is configured so as to be changed over when the detection or calculated value of the torque computing unit and the like exceeds the output of a device for setting the limitation on torque and the like, and the limiting characteristics of the limitation setting device is configured to be changed, based on output frequency command value, DC intermediate voltage value or the like.
