Abstract: Aiming at the control problem of industrial CT motion platform, especially the requirement of two-axis synchronous motion, the control system was studied, especially the synchronization motion was studied. A control system was designed based on the OMRON Sysmac automation platform, that included hardware, communication protocol, axis configuration and program. In order to satisfy the highprecision positioning requirements, full closed-loop control was adopted for the motion axis. Taking advantage of Omron PLC′s built-in electronic gear function, two kinds of synchronous motion mode were designed, and programs were written. The motion performance and positioning accuracy were tested on the platform with non-synchronous motion mode. The results indicate that the single-axis positioning is accurate, and the position deviation of synchronous motion between the synchronous axes is 0.8 μm, better than other modes. The system satisfies the requirements.
