Document Type and Number:
Japanese Patent JP6616391
Kind Code:
B2
Abstract:
A servomotor control device in a processing machine that processes an object to be processed on a press supporting unit driven by a servomotor includes: a pressure detection unit configured to detect an actual pressure applied on the object to be processed; a pressure command generation unit configured to generate a pressure command that commands a pressure that the object to be processed preferably receives; a pressure control unit configured to generate a speed command for the servomotor on the basis of the pressure command generated by the pressure command generation unit and the actual pressure detected by the pressure detection unit; and a speed command limiting unit configured to limit the speed command generated by the pressure control unit using a predetermined value.
