APPARATUS FOR CONTROLLING HYBRID CONTROL SERVOPRESS AND METHOD FOR CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To separately perform high-production work and high-accuracy work by using one press. SOLUTION: In a hybrid control servopress 1 in which an eccentric rotating mechanism 20 is driven with a servomotor 21 and a slide 3 is vertically moved by transmitting the rotating power of this eccentric rotating mechanism 20 to a slide 3 through a toggle link mechanism 15, the rotation of the servomotor 21 is controlled by a motor speed command rm which is calculated on the basis of the positional deviationεp of the slide 3 and a position gain G(θ) corresponding to the velocity ratio of the slide 3.
