1) The absolute accuracy when synchronizing with a BERO is a function of:
– the BERO switching time
– BERO hysteresis
– signal edge gradient of the BERO signal (dependent on the direction of rotation!) and the switching thresholds
in the drive; high >13 V, low < 5 V
– the search speed or the signal run times in the evaluation electronics
2) Distance–coded reference marks can be evaluated
