该无极调速的实现主要以西门子S7-1200系列的S7-1214plc(订货号:6ES7 214-1AG31-0XB0)控制机,以CM1241(订货号:6ES7 241-1CH30-0XB0)通信模块,以西门子MM420(订货号:6SE6 420-2UC17-5AA1)为控制对象,实现无极调速功能。对无极调速的架构做了系统介绍,分析了变频器的参数设定和USS协议,介绍了使用TIAV12对西门子PLC的程序设计实现功能的具体步骤。
The stepless speed regulation mainly to S7-1200 series Siemens S7-1214plc (order number: 6ES7 214-1AG31-0XB0) control machine to CM1241 (order number: 6ES7 241-1CH30-0XB0) communication module to Siemens MM420 (Order number: 6SE6 420-2UC17-5AA1) as the control object, to achieve stepless speed regulation. The architecture of stepless speed regulation is introduced systematically, the parameter setting of inverter and the USS protocol are analyzed, and the concrete steps of using TIAV12 to realize the function of Siemens PLC are introduced.
