Software Position Limit - Siemens SINAMICS V90 Operating Instructions Manual

Follow the steps below to perform referencing with this mode:
1. Set relevant parameters:
1)
2. Configure the signal SREF and CWL.
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.

Software position limit

The following two software position limits are available in the internal position control mode:
● positive position limit
● negative position limit
The function of software position limit only becomes active after going to reference. When
the actual position reaches one of the above-mentioned software position limits, motor speed
decelerates to 0.
