With the improvement of production technology, the motion control module of servo motor requires more precise position control. The SIMATIC S7-1200PLC designed and developed by Siemens has good modern process performance. It is given by pulse interface. The motor’s operational control functions are supported to meet current process requirements and are fully functional. This paper studied the application of SIEMENS S7-1200 PLC in the position control of Panasonic servo motor. This paper firstly explained the wiring steps of Panasonic servo motor A5 series hardware and PLC system, and then controled the displacement motion of servo motor through software program. Finally, the experiment was used to verify the correctness of the program. The results showed that the accuracy of the displacement operation could reach 0.1 mm, which could meet the performance requirements of position control.

Key words: S7-1200 PLC, servo motor, motion control, hardware setting, software configuration, experimental verification
