摘要
针对工业生产中电动机多段速调速控制的问题,采用了西门子S7-200PLC控制MM440变频器实现多段速调速控制,并通过WinCC监控软件和PLC通信对整个系统进行监控,检测电机的实时转速,真正达到实时监控的目的。详细阐述了MM440变频器3种实现多段速调速的控制方式,并对变频器的参数设置、PLC程序设计及监控画面的制作进行了讲解。实践证明:系统电路设计简单、成本低、功能完善,具有一定的应用价值。
This paper achieves the control of multi segment speed using Siemens S7 200 PLC controlling MM440 converter according to the problem of motor multi segment speed control in the industrial production.The system can detect the real time of motor speed and truly achieve real time monitoring purpose through the WinCC mo-nitoring software and PLC communication control-ling the whole system.This thesis detailedly de-scribes three multi segment speed control modes of the MM440 inverter and explains the parameters set of the inverter,the PLC program design,the production of the monitoring picture.Experiments prove that the system circuit is simple,low cost, perfect function,and has certain application value.
