Study on control system of high performance servo press based on OPC protocol

The control system of the 1000 kN servo press has been studied in the text. The double screw driven mechanical system has been used to satisfy the large-scale demands of the servo press. Through virtual spindle synchronous control and optimized design of mechanical structure, the trouble of synchronous control of the two motors has been solved. Aiming at the flexible and simply requirement of the motion curve, a kind of thrcc-spline-fitting curve programming method has been put forward in order to realize custom motion curve function of the servo press. The PC and motion controller architecture model has been adopted to the control system. The OPC communication protocol has been used to realize the parameters transferring function between PC and Siemens Simotion motion controller.
