发明名称 Servo press control system and servo press control method
摘要 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 press 1 in which an eccentric rotation mechanism 20 is driven by a servo motor 21 and the rotating power of the eccentric rotation mechanism 20 is transmitted to a slide 3 through a toggle linkage 15, thereby vertically moving the slide 3. In the control system and method, the rotation of the servo motor 21 is controlled in response to a motor speed command rm calculated based on the deviation epsilon p of the position of the slide 3 and a positional gain G(theta) preset according to a speed ratio of the slide 3.
