变频器在轧辊焊接机焊件组合变位控制中的应用

Application in the roll welding machine welds part combination change of position control of frequency converter

在变频器的应用中,控制方式主要有:一是传统的模拟量和开关量进行控制;二是通过串行总线应用USS协议进行控制。介绍了以PLC为核心的轧辊焊接机焊件组合变位控制中变频器的应用,详细阐述了两种控制方式的实现方法。

The eontrol method chiefly has in the application of frequency converter is that the capacity imitating and switch capacity of tradition are controlled;Secondly control by way of USS Protocol.This text has been introduced roll that takes PLC as the nucleus welding machine and has been wehled in piece positioning control application of frequency converter,and has detailed expounded two kinds of realization methods of eontrol method.
