1) The absolute accuracy for so–called synchronization with a BERO depends on the following:
– the switching time of the BERO
– the hysteresis of the BERO
– the signal edge gradient (rate–of–rise) of the BERO signal (depending on the direction of rotation) and the switching
thresholds in the drive; high > 13 V, low < 5 V
– the search speed and the signal runtimes in the evaluation electronics
2) Distancecoded reference marks can be evaluated
