Given the choice of signals, the frequency of the general frequency converter can also be given in a variety of ways, panel given, external given, external voltage or current given, communication mode given. Of course, the frequency of the frequency of the frequency converter can also be the sum of

Setting the starting mode of frequency converter, general frequency converter in the factory adjust by start from the panel, the user can choose according to the actual situation start mode, can use the panel, external terminal, communication mode and so on several kinds.

The frequency converter adopts the control mode, namely the speed control, the rotation distance control, the PID control or other ways. After adopting the control mode, we usually need static or dynamic identification according to the control precision.

Commonly used frequency converter, generally out of the factory, manufacturers have a default value for each parameter, these parameters are called factory values. In the case of these parameter values, the user can operate normally in the face panel operation mode, but the panel operation does not
