变频器的控制功能 第5讲 变频器的运行方式

AC Inverter's Control Function

变频器的运行方式是指变频器应该选择如何负载的工作方式。普通运行,是最常用的运行方式,它是在变频器最初设置的频率给定方式和运转指令方式下的运行方式。点动运行,就是变频器在停机状态时,接到点动运转指令后按点动频率和点动加减速时间运行。多段速运行,是指通过多功能输入端子的逻辑组合,可以选择多段频率进行多段速运行。另外本文还阐述了PID运行和简易程序运行。

The running method of AC inverter is how to select the right running way of the load. Normal running is the usual way in accordance with the preset frequency setting and command setting. Jog running is that AC inverter runs under the jog frequency, jog acceleration time and jog deccleration time. Multi-speed running is that AC inverter runs with the combination of multi-function terminals. And this paper also will describe the control of PID and simple PLC.
