Siemens SINAMICS V90 Operating Instructions Manual page 193

Follow the steps below to perform referencing with this mode:
1. Set relevant parameters:
2. Configure signals SREF and REF.
Refer to Chapter "Digital inputs/outputs (DIs/DOs) (Page 91)" for reference.
3. Trigger SREF to a rising edge to start referencing.
Note
During the referencing, if SREF is OFF, the referencing stops.
4. If the servo motor reaches the reference point, the signal REFOK (if configured) is output.
5. Switch off the signal SREF, and the referencing finishes successfully.
Encoder zero mark only (p29240=2)
In this mode, there is no cam available. The referencing is triggered by signal SREF. After
that, the servo motor accelerates to the speed specified in p2608 and the direction (CW or
CCW) is defined by p2604. When the servo motor reaches the first zero mark, it starts to
travel towards the reference point defined in p2600 with the speed specified by p2611. When
the servo motor reaches the reference point (p2599), the signal REFOK is output. Switch off
the signal SREF (1→0) and the referencing finishes successfully.
