F7491 and F7492, EPOS stop cam reached.

I have the same problem.

F7491 and F7492, EPOS stop cam reached.

There is a reference to it here:https://support.industry.siemens.com/cs/ww/en/view/109481721

But even when i try the forced solution, (P29300=6), the same alarm keep coming.

Its appears when the servo is in on state, and i start the reference mode to the encoder zero mark.

I use an single turn absolute encoder.

Anybody suggestions?

EDIT: "When either of signals CWL and CCWL is not assigned to any DI, the signal will be at a high level automatically"

Split from V90 IPOS control problem..

Next day the problem was gone.

I guess it is important to take all the power off for longer than 5 seconds...

Hope this is usefull for somebody.
