PLC及变频器在悬挂输送链同步控制中的应用

PLC and Inverters Used in Synchronous Control of Hanging Conveyer Chain

介绍了三台电机同步控制的几种方案,重点论证了可编程控制器(PLC)及变频器在悬挂输送链同步控制中的应用。由于使用了位置与速度双闭环控制、触摸屏(POD)显示和独特的子程序设计,系统具有安全可靠、高效平稳、功能完善、操作维修简便等优点,在工厂自动化中取得了显著的经济效益。

This paper introduces a few programs of synchronous control in three motors,major analyzes application of Programmable Logic Controller （PLC） and Inverfers in synchronous control of Hanging Conveyer Chain.Because of use position and speed double closed control,Programmable Operation Display （POD） display,original program,this system has advantages of safety,reliability,high efficiency,stable,perfect function,convenience operation and repair,gain remarkable economy benefit in automatic factory.
