In the sediment of water mixing process,speed controling is more stable, and it can be operated at different speeds; in the processing of dragging,it needs more reliability . Thus, PLC controlling motor is applied to mixing and dragging control system gradully.This article describes design and implementation process of the PLC-based motor controlling system . PLC,Inverter, encoders, motors, mixers and sensors are combined to form a simple, complete automatic control system.Programs are designed and wrote into PLC through the software platform of Delta WPLSoft, then control multi-speed motor operation.In this paper the realization of high-speed counting is described valuablely. High-speed counter can control the dragging systems precisely, and keep the data in the fixed register in order to make other equipments operate and monitor the system convientely.Key words: PLC motor high-speed counter目 录第一章 绪论111 题目来源及课题意义112 文章概述113 设计思路2第二章 电动机篇321 电动机概述及分类322 交流异步电动机423 电动机变频调速524 变频调速的控制原理7第三章 编码器篇931 编码器杂谈9311 编码器的发展史9312 编码器的分类932 旋转编码器10321 旋转编码器的工作原理10322 旋转编码器的分辨率和精度1133 台达编码器ES3-02CN694112第四章
