It is controlled by a programmable controller. The design principle and method are analyzed and summarized. Stepping motor has the advantages of fast start stop, positioning and accurate stepping, etc., and the daily production and life are more common, and the control accuracy is high. It is widely used in industrial process control and instrument control. PLC control system is introduced, including hardware structure and principle, and the principle and method of PLC control system design. Taking five phase motor control as an example, the application of SIEMENS PLC in motor control is expounded. Its basic principle, hardware preparation and software design are embodied in this article. The subdivision drive method can achieve high accuracy and stability, and is favorable for motor quality and torque fluctuation. The contents of this paper include PIC external wiring diagram, I/O address allocation, control flow ...
