Fig. 2-13 Zero mark selection with BERO
Zero mark evaluation with BERO must be parameterized as the referencing mode:
MD34200 $MA_ENC_REFP_MODE = 5
Negative edge evaluation
In the case of a referencing operation with a negative edge evaluation of the BERO signal:
MD34120 $MA_REFP_BERO_LOW_ACTIVE = FALSE
synchronization is with the next encoder zero mark encountered after the BERO is exited.
Positive edge evaluation
In the case of a referencing operation with a positive edge evaluation of the BERO signal:
MD34120 $MA_REFP_BERO_LOW_ACTIVE = TRUE
synchronization is with the next encoder zero mark encountered after the BERO is
approached.
If, mechanically, the BERO is sized in such a way that the positive BERO signal covers the
entire width of the encoder zero mark, the encoder zero mark will be reliably detected in both
traversing directions.
