SEW变频器MCLTPB系列型号：
PLC控制系统故障是指其失去了规定功能，一般指整个生产控制系统失效的总和，它又可分为PLC故障和现场生产控制设备故障两部分。PLC系统包括中央处理器、主机箱、扩展机箱、I/O模块及相关的网络和外部设备。现场生产控制设备包括端口和现场控制检测设备，如继电器、接触器、阀门、电动机等
口诀是现场快速求算电动机空载电流具体数值的口诀，它是众多的测试数据而得。它符合"电动机的空载电流一般是其额定电流的1/3"。同时它符合实践经验："电动机的空载电流，不超过容量千瓦数便可使用"的原则（指检修后的旧式、小容量电动机）。口诀"容量八折左右求"是指一般电动机的空载电流值是电动机额定容量千瓦数的0.8倍左右。中型、4或6极电动机的空载电流，就是电动机容量千瓦数的0.8倍；新系列，大容量，极数偏小的2级电动机，其空载电流计算按"新大极数少六折"；对旧的、老式系列、较小容量，极数偏大的8极以上电动机，其空载电流，按"是小极多千瓦数"计算，即空载电流值近似等于容量千瓦数，但一般是小于千瓦数。运用口诀计算电动机的空载电流，算值与电动机说明书标注的、实测值有一定的误差，但口诀算值完全能满足电工日常工作所需求。
可编程控制器的工作过程包括两部分：自诊断及通信响应的固定过程和用户程序执行过程，如图1所示。PLC在每次执行用户程序之前，都先执行故障自诊断程序、复位、监视、定时等内部固定程序，若自诊断正常，继续向下扫描，然后PLC检查是否有与编程器、计算机等的通信请求。如果有与计算机等的通信请求，则进行相应处理。当PLC处于停止（STOP）状态时，只循环进行前两个过程。而在PLC处于运行（RUN）状态时，PLC从内部处理、通信操作、输入扫描、执行用户程序、输出刷新五个工作阶段循环工作。每完成一次以上五个阶段所需要的时间称为一个扫描周期。
