Description: Displays the P component of the controller for speed adaptation.
Description: Displays the I component of the controller for speed adaptation.
Description: Displays estimated (speed) signals of the motor model.
r1773[0]: Displays the estimated (mechanical) slip of the motor model.
r1773[1]: Displays the estimated input speed of the motor model.
Index: [0] = Slip speed estimated
[1] = Speed estimated
Description: Sets the offset voltage in the alpha direction; this compensates the offset voltages of the drive converter/inverter at
low speeds. The value is valid for the rated (nominal) pulse frequency of the power unit.
Note: The value is pre-set during the rotating measurement.
Description: Sets the offset voltage in the beta direction; this compensates the offset voltages of the drive converter/inverter at
low speeds. The value is valid for the rated (nominal) pulse frequency of the power unit.
Note: The value is pre-set during the rotating measurement.
