Siemens SINAMICS V90 Operating Instructions Manual page 159

Follow the steps below to perform referencing with this mode:
1. Set relevant parameters:
1)
2. Configure signal REF.
Refer to Section "Digital inputs/outputs (DIs/Dos) (Page 99)" for reference.
3. Set STW1.11 (0→1) to start referencing.
Note
During the referencing, if STW1.11 is set to 0, the referencing stops.
4. If the servo motor reaches the reference point, the signal REFOK (if configured) is output.
5. Set control word STW1.11 to 0, and the referencing finishes successfully.
Encoder zero mark only (p29240=2)
In this mode, there is no cam available. The referencing is triggered by control word
STW1.11. 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. Set control word STW1.11 to 0 and the referencing finishes successfully.
