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
Table 5-15 Mode of operation of p0431
Incremental without
zero mark
C/D track Shifts the commutation
with respect to the C/D
track.
Hall sensor Does not influence the
Hall sensor. The Hall
sensor must be me‐
chanically adjusted.
Pole position No effect
identification
Note
When fault F07414 occurs, p1990 is automatically started; if p1980 ≠ 99 and p0301 does not
refer to a catalog motor with an encoder that is adjusted in the factory.
