IC693CMM321 亿询就心动

设计过程中应注意梯形图与继电器电路图的区别。梯形图是一种软件，是PLC图形化的程序，PLC梯形图是串行工作的，而在继电器电路图中，各电器可以同时动作（并行工作）。

    移植设计法主要是用来对原有机电控制系统进行改造，这种设计方法没有改变系统的外部特性，对于操作工人来说，除了控制系统的可靠性之外，改造前后的系统没有什么区别，他们不用改变长期形成的操作习惯。这种设计方法一般不需要改动控制面板及器件，因此可以减少硬件改造的费用和改造的工作量。

 某卧式镗床继电器控制系统的电路图，包括主电路、控制电路、照明电路和指示电路。镗床的主轴电机M1是双速异步电动机，中间继电器KA1和KA2控制主轴电机的起动和停止，接触器KM1和KM2控制主轴电机的正反转，接触器KM4、KM5和时间继电器KT控制主轴电机的变速，接触器KM3用来短接串在定子回路的制动电阻。SQ1、SQ2和SQ3、SQ4是变速操纵盘上的限位开关，SQ5和SQ6是主轴进刀与工作台移动互锁限位开关，SQ7和SQ8是镗头架和工作台的正、反向快速移动开关。
