Morara Grinding : Part Origin Missing Alarm

Hello,

Can you please help in resolving the below issue:

Machine: Morara Grinding machine - OD/ID grinding can be done in this machine.

During new part setup for OD grinding, the grinding operator will take diamond(dresser) origin & Part Origin, after the sequence is over, when he start the cycle - the machine will stop with " Part Origin Missing" alarm. Tried doing part origin again & again, but same alarm repeats.
But if you the NC file (machine run with Siemens 840d sl) - the alarm will go off, not sure how it goes off. But it will repeat again after one month or 20 days. Again i will load NC file.
Not sure why it happens. Pls help in resolving.
