Speed control

The U/f control mode is an encoder-less mode and calculates the actual speed value. The calculation is always based on the electrical values of the motor. Therefore, information from a potentially existing encoder system is not used.

If an encoder is parameterized in the encoder assignment as "Actual speed source", the speed measured by this encoder is issued as the actual speed by the inverter.

Otherwise, the model speed calculated by the control mode based on stator frequency and slip is issued as the actual speed.

The control mode does not have a higher-level speed controller, therefore speed controller parameterization is not possible. An acceleration and torque precontrol is also not possible.
