Making parameter entries / commutation setting
Incremental measuring system
1. Activate automatic determination of the commutation angle offset with p1990 = 1.
Alarm A07971 is output while the commutation angle offset is being determined.
2. Set the drive enable signals (OFF3, OFF2, OFF1).
This results in coarse synchronization. A successful coarse synchronization is indicated
by the parameter r1992.9.
3. Move the drive over the zero mark.
When the drive moves over the zero mark, the angular commutation offset is entered into
p0431. p1990 is automatically set to 0 after the angular commutation offset has been
determined. Alarm A07965 is displayed as a prompt to save the change in a non-volatile
fashion.
Absolute measuring system
Set p1990 = 1 before activating the enable signals.
By activating the enable signals, the angular commutation offset entered into p0431 and
p1990 is automatically set to 0. Alarm A07965 is displayed as a prompt to save the change
in a non-volatile fashion.
