根据动作顺序诊断故障。对于自动控制，其动作都是按照一定的顺序来完成的，通过观察系统的运动过程，比较故障和正常时的情况，即可发现疑点，诊断出故障原因。如某水泵需要前后阀门都要打开才能开启，如果管路不通水泵是不能启动的。
交流回路中的电容器投入电网或从电网中切除时，接触器选择应考虑电容器的合闸冲击电流。一般地，接触器的额定电流可按电容器的额定电流的1.5倍选取，型号选CJ10、CJ20等。
对于恒功率负载和恒转矩负载，在选择电动机调速方案时，要使电动机的调速特性与生产机械的负载特性相适应，这样可以使电动机得到充分合理的应用。

闸刀开关种类很多，有两极的（额定电压250V）和三极的（额定电压380V），额定电流由10A至100A不等，其中60A及以下的才用来控制电动机。常用的闸刀开关型号有HK1、HK2系列。表1-1列出了HK2系列部分技术数据。
电源变压器TB将380V的交流电压降到36V的安全电压，供照明用。照明电路由开关K控制灯泡EL。熔断器FU3用作照明电路的短路保护。冷却泵电动机M2运行指示灯HL16.3V电压供电源指示HL2、刻度照明HL3。总结：①主轴电动机采用单向直接起动，单管能耗制动。能耗制动时间用断电延时型时间继电器控制。②主轴电动机和冷却泵电动机在主电路中保证顺序联锁关系。③用电流互感器检测电流，监视电动机的工作电流。
