Servo press control system based on bus mode

The utility model discloses a servo press control system based on bus mode belongs to servo control technical field. Including man-machine interaction module, motion control module, outer module and the motion executable module of expanding of drive, the motion control module includes main control unit and grating chi, the input/output unit, data interchange and the memory cell, the AD conversion unit that are connected with main control unit respectively, pass through CAN bus connection between the main control unit of man-machine interaction module and motion control module, the motion executable module is connected to the motion control module. The grating chi is passed through in the adoption as position feedback, can accurate displacement volume of gathering the slider feed back main control unit, improves the control accuracy of servo press greatly, adopt 2 servo motor to realize the synchronous and grating chi cooperation of moment, realize the closed loop motion control of high accuracy, improved servo press response speed and stability.
