摘　　要：以三菱FX2N系列PLC和三菱FR-D720变频器、普通三相异步电动机为主要设备,设计响应给定输入信号变化的开环变频调速控制系统。将现在应用最广泛的PLC和变频器综合起来,主要功能实现了变压变频调速、电机的正反转、加减速以及快速制动等。Here, we use MITSUBISHI FX2N PLC and MITSUBISHI FR - A700 frequency changer as the main equipment in this project to design a fixed response has supply and import signal varying frequency changed control system with no feedback. Gather the programming Logic controller and frequency changer to achieve vary frequency , motor changed the rotation from one side to the opposite, higher or lower the speed of motor , sharp stop and so on.

关 键 词：PLC 变频器 调速
