摘要

基于PLC的步进电机控制系统由硬件部分和软件部分组成。硬件部分由可编程序控制器、步进驱动器、步进电机构成。步进驱动器、可编程序控制器、步进电机需要通过正确的逻辑连接起来。但是还起不到控制的作用，所以需要进行软件部分的设计。软件部分包括程序编制以及程序仿真。将此控制系统应用在带锯机摇尺中，可以实现带锯机摇尺工作的自动化。由于控制系统中没有位置检测装置，所以此系统属于开环控制。如果在控制系统中增加位置检测装置组成闭环系统，可以提高木材的加工精度。

Abstract

The step motor control system based on PLC is composed on hardware and software.The hardware is made up of programmable logic controller,stepping drivers and stepping motor. Stepper drivers,programmable logic controller,stepper motors need to be connected through the correct logic.But it doesn’t work. So it needs to design the software part. The software includes programming and simulation.Apply this control system to the band saw machine,it can realize the automation of band sawing machine.Because there is no position detection device in the control system,So this system is open loop control.If the position detection device is added in the control system,the closed loop system is formed,it can improve the processing accuracy of wood.
