【正文】 bstract:In the field of programming, I/O expansion, Communication interface, adjustments of switches and simulation and some special function modules such as the application of high speed pulse input and output, the PLC has already met demands of users. But the PLC will continue to improve and develop, as the development of application requirements and related technical performance. This article chiefly discusses the principle and driven approach of the stepping motor, and how to control it based on the S7200 PLC. The article is about how the PLC controlling the twophase hybrid stepping motor. With the switch button, it can function as: start,positive rotation， inversion. Key words: S7200 PLC. twophase hybrid stepping motor, PLC programming. 基于 PLC 的步進(jìn)電機(jī)的控制 iii 目錄 第一章 緒論
