 DA模块:版辊旋转，刀盘旋转，拖板移动分别用3台电动机拖动，变频器根据输入的版辊直径，版辊长度通过调用公式来调节电动机转速，保证磨削出一定锥度的表面。三个速度和版辊直径，长度之间存在着一定的机械关系，而这种折算关系存储在PLC中并在磨削前自动调用出来，拖板的横向移动距离用接近开关检测，电机每转一周检测5个开关（丝杠前进10mm），计5次数，一次计数就移动2mm，停止时已经记下一定的距离，当拖板退回去的时候可以根据折算好的计数值自动停止移动。无论刀盘转速还是版辊转速、拖板移动速度发生波动，都会影响磨削出来的表面精度，因此，当其中一个速度发生波动时，另外两个的转速必须迅速跟踪。无论手动操作时设定速度还是根据版辊直径，长度通过公式求得刀盘、版辊、拖板速度值，都要将其值传给三菱变频器。为此，我们增加4DA模块。该模块提供4个输出通道（要用到3个通道）,电压输出模式，对应于0V-+10V。电流输出模式，分别对应于4mA-20mA。
