ABSTRACT:
High production processing and high accuracy processing are selectively performed with a single press. To this end, there are provided a system and method for controlling a servo press1in which an eccentric rotation mechanism20is driven by a servo motor21and the rotating power of the eccentric rotation mechanism20is transmitted to a slide3through a toggle linkage15,thereby vertically moving the slide3.In the control system and method, the rotation of the servo motor21is controlled in response to a motor speed command rm calculated based on the deviation ε p of the position of the slide3and a positional gain G(θ) preset according to a speed ratio of the slide3.
