Referencing then proceeds as follows:
● Via the PROFIdrive encoder interface, SINAMICS S receives the request for a reference
mark search.
● Using the parameterization, SINAMICS S determines the zero mark depending on the
BERO signal.
● SINAMICS S provides the (possibly corrected) zero mark position as reference mark via
the PROFIdrive encoder interface.
Note
A
t high speeds or if the distance between the BERO signal and the following zero mark is
too low, then it is possible that the required, next zero mark is not detected, but instead, a
subsequent one due to the computation time. Due to the known zero mark distance, in
this particular case, the determined position is correspondingly corrected.
When using a measuring gear, the zero mark position depends on the motor revolution.
In this case, a correction is also performed and for each motor revolution a reverse
calculation is made back to the position of the zero mark with the shortest distance BERO
signal ↔ zero mark.
