3. The converter moves the motor in the selected direction or in both directions.
During the measurement, the converter signals the alarm A07961.
4. When the converter has calculated all the interpolation points of the friction characteristic,
the converter stops the motor.
The converter averages the measurement results of the positive and negative directions of
rotation.
