在当今变频器的控制应用中,控制方式主要有通过模拟量和开关量进行控制和通过串行总线应用通用串行通信接口协议(USS协议)进行控制两种。介绍以可编程序控制器(PLC)为核心的埋弧焊接控制系统,对变频器进行控制,控制上应用通用串行通信接口协议。采用通用串行通信接口协议对变频器控制可以减少系统布线,增强系统的可靠性,整个现场总线控制系统抗干扰性强。
In today’s frequency converter control applications, the main control methods are controlled by analog and digital control and through the serial bus application of Universal Serial Communication Interface Protocol (USS protocol) to control two. The submerged arc welding control system with programmable logic controller (PLC) as its core is introduced. The universal serial communication interface protocol is applied to control and control the inverter. The use of universal serial communication interface protocol on the inverter control can reduce system wiring and enhance system reliability, the entire field bus control system strong anti-interference.
