The circuit diagram use is very convenient and simple control. The location of the three-phase asynchronous motor control and automatic control circuit back and forth is increasingly important in industrial production, we need to add new control function on the basis of the design. Key words : Position control and automatic control circuit 、 time delay 、a brief stop back and forth . 目录引言........................................................................................................................................... 1 1 位置控制与自动往返控制线路的认识................................................................... 2 实物图.................................................................................................................................. 3 电路图.................................................................................................................................. 3 ....................................................................................................3 自动循环控制线路原理.......................................................................................................3
