Servomotor controller for reducing power peak

A servomotor controller comprising:

• at least one first converter circuit that performs power conversion between AC power on a side of an AC power supply and DC power on a DC side;
• at least one first inverter circuit that performs power conversion between the DC power on the DC side of the first converter circuit and one of AC power supplied to a first servomotor and AC power regenerated from the first servomotor;
• at least one second converter circuit that performs power conversion between the AC power on the side of the AC power supply and DC power on a DC side;
• at least one second inverter circuit that performs power conversion between the DC power on the DC side of the second converter circuit and one of AC power supplied to a second servomotor and AC power regenerated from the second servomotor;
• and
• a power calculation unit that calculates an amount of power consumed or regenerated in the first servomotor,
• wherein the power conversion by the second converter circuit and the second inverter circuit is controlled so that the power regenerated from the first servomotor is supplied to the second servomotor through the AC power supply or the power regenerated from the second servomotor is supplied to the first servomotor through the AC power supply, on the basis of the amount of power calculated by the power calculation unit.
