Signal propagation delay compensation
The signal propagation time can cause corruption of the absolute position detected by the
NC. The signal propagation time can be compensated for in any direction:
MD31122 $MA_BERO_DELAY_TIME_PLUS (BERO delay time plus)
MD31123 $MA_BERO_DELAY_TIME_MINUS (BERO delay time minus)
Note
Prerequisite for a correct compensation of signal propagation time is drives of type
SIMODRIVE 611 digital. The compensation times are pre-set in delivery condition in such a
way that changes are usually not required.
Creep velocity
If with the approach of BERO, it is to be proceeded with the parameterized reference point
creep velocity (MD34040 $MA_REFP_VELO_SEARCH_MARKER) then "BERO with
projected start velocity with spindles" must be parameterized as reference mode:
MD34200 $MA_ENC_REFP_MODE = 7
