Use the switch output of PLC to control the inverter.The switching output of PLC can generally be directly connected with the switching input of the inverter.This control method has simple wiring and strong anti-interference ability.The switch output of PLC can be used to control the start/stop,forward/reverse,jog,multi-stage speed and addition and subtraction time of the inverter,which can achieve more complex control requirements,but only step-by-step speed regulation.

利用PLC的开关量输出控制变频器。PLC的开关输出量一般可以与变频器的开关量输入端直接相连。这种控制方式的接线简单，抗干扰能力强。利用PLC的开关量输出可以控制变频器的启动／停止、正／反转、点动、多段速和加减时间等，能实现较为复杂的控制要求，但只能有级调速。
