可编程序控制器在变频器通信和控制中的应用

The application of PLC to the frequency converter's control and communication

讨论了采用基于RS485接口的USS通信协议对变频器进行控制的方法和程序设计,有效地减少了系统的布线,提高了系统的抗干扰能力。

The programming and solution to the control of frequency converter are discussed based on the USS agreement through the RS485 interface,which efficiently minimizes the wiring and improves the anti-jamming ability of the system.
