首先介绍了行程控制的传统方法及其优、缺点,然后用实例阐述了使用旋转编码器(PG)和可编程序控制器(PLC)相结合,从硬件和软件两方面入手,实现对机械行程精确控制的一种方式。
Firstly, the traditional method of stroke control and its advantages and disadvantages are introduced. Then, an example is given to illustrate the use of rotary encoder (PG) and programmable logic controller (PLC) in combination with hardware and software to realize mechanical stroke A way to precisely control.
