Abstract
A servomotor controller includes a first and a second converter circuit that perform conversion between AC power of a power supply and DC power, a first inverter circuit that performs conversion between the DC power on the DC side of the first converter circuit and AC power on the side of a first motor, a second inverter circuit that performs conversion between the DC power on the DC side of the second converter circuit and AC power on the side of a second motor, and a power calculation unit that calculates an amount of power of the first motor, wherein control is performed so that the regenerative power of the first motor is supplied to the second motor through the power supply or the regenerative power of the second motor is supplied to the first motor through the power supply, on the basis of the amount of power.
