PLC控制逻辑与传统的继电器接触器控制系统基本一致，其工作过程如下：
:起动时，按下起动按钮SB1,X400常开触点闭合，Y430线圈接通并自锁，KM1线圈接通，主触头吸合，电动机串入限流电阻R开始起动，同时Y430的两对常开触点闭合，当电动机转速上升到某一定值时，KS1的常开触点闭合，X402常开触点闭合，M100线圈接通并自锁，M100的一对常开触点接通Y432的线圈，KM3线圈有电主触头吸合，短接起动电阻，电机转速上升至给定值时投入稳定运行。制动时，按下停机按钮SB2，X401常开触点断开Y430线圈，使KM1失电释放，而Y430的常闭触点接通Y431线圈，制动用的接触器KM2线圈通电，对调两相电源的相序，电动机处于反接制动状态。与此同时，Y430的常开触点断开Y432的线圈，KM3失电释放，串入电阻R限制制动电流。当电动机转速迅速下降至某一定值时，KS1常开触点断开，X402常开触点断开M100的线圈，M100的常开触点断开Y431线圈，KM2失电释放，电动机很快停下来。过载时，热继电器FR常开触点闭合，X403的两对常闭触点断开Y430和M110的线圈，从而使KM1或KM2失电释放，起到过载保护作用。上述控制过程指令程序如下：
