Abstract
A controller for an electric servo press includes: a press load sensor for detecting a pressure force of the slide; a pressure-force determination device for determining whether the pressure force of the slide reaches one or a plurality of different pressure-force setting values based on the one or the plurality of different pressure-force setting values and an output signal of the press load sensor, and for generating a pressure-force achievement signal each time the pressure force of the slide reaches each of the one or the plurality of different pressure-force setting values; a servo motor drive controller for controlling driving of the servo motor; and a motion command device. In response to the pressure-force achievement signal, switching of a drive control mode by the servo motor drive controller is switched, and/or a motion to be commanded by the motion command device is switched.
