Dependencies

Table legend:
1. Encoder track monitoring
2. Zero mark tolerance
3. Freezing the speed setpoint
4. Adjustable hardware filter
5. The measuring time can be set to evaluate zero speed
6. Sliding averaging of the speed actual value
7. Edge evaluation of the zero mark
8. Signal edge evaluation (1x, 4x)
9. Pole position adaptation
10. Pulse number correction in the event of faults (pole position for commutation is also
11. "Tolerance band pulse number" monitoring

Reference mark
(or zero mark)
Correction
increment per zero
mark = +1 quadrant
If A3x131 is parameter-
ized as alarm, larger
deviations are also
corrected.
For each detected zero
mark, the
tolerance window size is
corrected as maximum.
