摘　　要：变频器通常用数字量输入端控制有级调速、用模拟量输入端控制无级调速,本文论述基于PLC在数字量输入端不能满足变频器多速段运行时,如何利用模拟量输入端来控制变频器的多速段运行。Inverter usually use digital input to control stepped speed regulation and analog input to control stepless speed regulation.This article discusses how to use the analog input to control the multi-speed operation of the inverter when the digital input can not meet the multi-speed operation of the inverte r based on PLC.

关 键 词：变频器 数字量输入 模拟量输入 PLC 多速段
