Abstract：According to the characteristic of printing technology and traditional synchronous control system that its power supply is based on mechanical axes, a synchronous control system based CAN field bus was introduced to meet the requirements of printing mechanism. Meanwhile, the generation mechanism about synchronous motion data in primary station is presented. The clock synchronization mechanism and the protocol between primary station and slave stations are also designed in the synchronous control system. The result was proved.
