设计这种步进阶梯时要注意以下问题:(1)在一个自动工作循环内,移位寄存器的移位数据输入端IN只允许起动时输入一个单脉冲信号。也就是说起动时只能输入移位数据“1”。步进阶梯的工作原理就是根据输入的数据“1”,在移位寄存器中逐步向高位移位来实现逐步得电和逐步失电。所以输入端IN要串联每个移位输出位的常闭触点;(2)移位寄存器对移位脉冲输入端开关的抖动非常敏感。若开关抖动一次,相当于多输入了一个移位脉冲,移位数据“1”随之多移了一位。由于接点式开关被触发时难免产生抖动。为消除这种影响,在移位脉冲输入端的步1输入回路,必须串联移位寄存器0位(本例为M20)的常闭触点,一旦移位数据移入M20位,便断开步1的输入回路;而从步2开始,每步的输入回路也要串联上一位的常开触点。例如步2的输入回路要串联上一位M20的常开触点。这样,当移位到步2转步主令信号对应的M21位时,便立即断开步2的输入回路。采用这样的移位脉冲输入回路结构,可确保每步的转步输入信号持续时间只有PLC的一个扫描周期(一般只有几Ms),因开关的抖动时间远大于PLC的一个扫描周期。所以可有效地消除开关抖动的影响。
