摘要
电动机安全稳定的工作对于企业生产十分重要,尤其对于大型设备的运转,在周围环境比较复杂的情况下,可以通过PLC控制变频器,达到远距离控制电机的目的。通过对变频器进行不同频率的参数设置,采用S7-200PLC控制西门子MM420系列的变频器的DIN端口,从而实现电动机的多段速调速控制。
The work of the security and stability of motor is very important for enterprise production, especially for large equipment operation,under the condition of the surrounding environment is complicated, by means of PLC to control frequency converter, to achieve the objective of the remote control motors. Through the different frequency parameter Settings of the inverter, using the Siemens S7-200 PLC control the DIN port of MM420 series inverter, thus to realize the multistage speed of motor speed control.
