José,
I'm a bit confused by your request. In the summary you talk about an issue with the following error but in the text body you are talking about problems with finding the Index. Is this related? Can you run normal linear moves without problems (both, in open and in closed loop mode)?
Please provide also the following information:
- Type of NI-Motion board (73xx)
- NI-Motion driver version (7.x)
Thanks and best regards,
Jochen Klier
