Commutation angle offset commissioning support (p1990)
The function for determining the commutation angle offset is activated via p1990=1. The
commutation angle offset is entered in p0431. This function can be used in the following
cases:
● Single calibration of the pole position for encoders with absolute information
(exception: The Hall sensor must always be mechanically adjusted.)
● Calibrating the zero mark position for fine synchronization
