Abstract
“(PLC) the procedure designer the professional manager authentication test practiced link's graduation design as the CETTIC nation programmable controller”, this article elaborated produced had the high performance price compared to miniature programmable controller FX2N-48MR using the Mitsubishi Corporation series PLC is system's master control unit, the control exchange three-phase asynchronous motor, the conveyor belt stepless speed regulation use “Mitsubishi” the MISUBSHI frequency conversion driver and the frequency conversion electrical machinery realizes. This system has used the programmable controller which fully in training narrated (PLC) various design knowledge and the method, cause this system reliably stable, enables its application scope to obtain the expansion.
