题目：机械滑台工艺流程控制系统设计（B）

实训学生需要完毕2个基础实训项目和1个综合型自主实训项目的训练。

一、基础实训项目一：变频器对电机的运营控制

一）实训目的

1、进一步巩固掌握PLC基本指令功能的及其运用方法；

2、根据实训设备，纯熟掌握PLC的外围I/O设备接线方法；

3、掌握异步电动机变频调速原理，熟悉变频器的用法。

二)实训设备

PLC主机单元模块、电位器、MM440(或MM420)变频器、个人计算机PC、PC/PPI编程电缆。

三)工艺控制规定

使用变频器实现异步电动机的可逆调速控制，即可以电动机可正反向运营、调速和点动功能。参考电气原理图见教材p85，速度控制有两种方式：（1）由外接的电位器控
