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 Motor Module.
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 Motor Module.
Note: The value is pre-set during the rotating measurement.
Description: Induction motor (ASM):
Displays the difference between the motor model flux angle and the transformation angle.
Permanent magnet synchronous motor (PEM):
Displays the difference between the motor model angle and the encoder angle.
Description: Displays the absolute value of the flux of the motor model.
