Title: SERVOMOTOR CONTROL DEVICE
Abstract:
The purpose of the present invention is to obtain a servomotor control device capable of selectively reducing switching noise and switching loss with a simple circuit configuration. This servomotor control device 6 is provided with: an IPM5 that is a semiconductor module including an inverter circuit 3, which inverts a direct current voltage into an alternating current voltage and outputs the alternating current voltage to a servomotor 7, and an inverter driving circuit 10, which drives the inverter circuit 3; and a supplied voltage control unit 18 which controls a supplied voltage to the IPM5 according to the state of the servomotor 7, on the basis of information from an encoder 17 mounted to the servomotor 7, an output current from the inverter circuit 3, and command information from the outside.
