摘要
步进电动机具有控制方法简单、易于实现数字控制等优点,应用S7-200PLC可较容易实现对其控制。但是,由于S7-200PLC只有2个高速脉冲输出口,只能对2台步进电动机发出走步脉冲。当同控制的步进电动机超过2台时,PLC就无法进行控制。针对该问题,介绍了应用PLC和EM253位控模块对步进电动机进行控制的方法,进行了硬件和软件相关设计。
Stepper motor control is simple ,easy to realize the advantages of digital control ,and S7-200PLC can easily realize the control over it. However, because S7-200PLC has only 2 high speed pulse output ports, PLC cannot control more than 2 stepper motors at the same time. Aiming at this problem, the application of PLC and EM253 positioning module for the stepper motor control method was introduced, and the hardware and software were designed.
