西门子变频器外部端子操作应用

Study on External Terminal Application of SIEMENS VFD

作为一种典型的工业控制器件,变频器广泛应用在工业自动化控制系统中。变频器配合普通交流电动机在某些场合可以代替步进或伺服电动机。西门子变频器通常有两种控制方式,操作面板控制模式和外部端子控制模式,主要讲述西门子变频器常用外部端子的功能及作用,以及通过参数设定结合外部端子对交流电动机进行运行控制。

SIEMENS VFD is widely used in practice production with the development of industry technology. Sometimes VFD and AC motor can replace the step motor or servo motor in automation control system. VFD has two control methods. One is the control panel and the other is external terminal control. In this paper we are going to talk about the function and application of external terminal in SIEMENS VFD.
