西门子变频器网络控制参数的设计方法

The parameter design of SIEMENS inverter in network control system

西门子变频器在PROFIBUS网络控制系统中得到了广泛应用,针对MM变频器的工作特点,探讨了MM系列变频器在网络中的建立,分析了PROFIBUS DP网络的拓扑结构,变频器GSD文件的导入,详细讨论了网络系统中变频器控制字(PQW)和状态字(PIW)的数据格式,阐述了变频器控制参数与通信参数的设计方法,实践证明这种方法实用可行。

The SIEMENS inverter is used in the profibus fieldbus very widely, for the characteristics of this inverter. The establish of MM serial inverter in the fieldbus is analyzed, The topological architecture of PROFIBUS DP, and the access to GSD document of inverter are described in detail. Finally the style of PQW and PIW in the fieldbus is introduced, the control and communication parameter are given, and it is a usable method proved by practice.
