4 PLC的软件控制逻辑

    由滑台的PLC控制方法可知，应使步进电机的输入脉冲总数和脉冲频率受到相应的控制。因此在控制软件上设置一个脉冲总数和脉冲频率可控的脉冲信号发生器；对于频率较低的控制脉冲，可以利用PLC中的定时器构成，如图2所示。脉冲频率可以通过定时器的定时常数控制脉冲周期，脉冲总数控制则可以设置一脉冲计数器C10。当脉冲数达到设定值时，计数器C10动作切断脉冲发生器回路，使其停止工作。伺服机构的步进电机无脉冲输入时便停止运转，伺服执行机构定位。当伺服执行机构的位移速度要求较高时，可以用PLC中的高速脉冲发生器。不同的PLC其高速脉冲的频率可达4000~6000Hz。对于自动线上的一般伺服机构，其速度可以得到充分满足。MKS MASS FLOW CONTROLLER 1/4"VCR, 2000 SCCM, N2, 179A23CR3BM, SHIPSAMEDAY1617C3
