The background of this paper is Rotary Screen Printing Machine(RSPM),and the paper need to resolve the printing flower dislocation phenomenon caused by synchronization between each motor, and by the synchronization between rotary screen motor and the conduction band. The paper presented overall scheme, and analyzed, designed and realized synchronous control arithmetic design based on system hardware platform. Through some related experimental results proved that the distributed system based on CAN bus(CANOpen protocol) worked stably, each motor transmitted independently and could run synchronously , and the results verified the correctness and feasibility of distributed structure scheme used for RSPM system.
