3.2 进给速度控制

伺服机构的进给速度取决于步进电机的转速，而步进电机的转速取决于输入的脉冲频率;因此可以根据该工序要求的进给速度,确定其PLC输出的脉冲频率:

f=Vf/60d (Hz) （2）

式中 Vf——伺服机构的进给速度(mm/min)

3.3 进给方向控制

进给方向控制即步进电机的转向控制。步进电机的转向可以通过改变步进电机各绕组的通电顺序来改变其转向;如三相步进电机通电顺序为A-AB-B-BC-C-CA-A…时步进电机正转;当绕组按A-AC-C-CB-B-BA-A…顺序通电时步进电机反转。因此可以通过PLC输出的方向控制信号改变硬件环行分配器的输出顺序来实现，或经编程改变输出脉冲的顺序来改变步进电机绕组的通电顺序实现。
