PLC高速计数器在位置控制中的应用

The Application of PLC High Speed Counter in Position Control

本文介绍了一种位置的闭环控制方法。它利用旋转编码器、变频器速度卡和PLC组成闭环系统,由PLC中的高速计数器来检测位置。文中以电梯为例详细介绍了控制方法的硬件组成并设计了绝对计数方式的位置控制程序。

This paper introduces a new way of position control that adopts rotating encoder, velocity card of transducer and PLC to consist of a close-circle system and examine position with high speed counter of PLC.The paper with a example of elevator presents composition of handware and the design process of absolute counting position control program.
