Hi all. Can someone tell what parameter on a fanuc OM-C adjusts spindle orientation? I need to adjust the spindle about a 1/4 turn and the fine adjustment on the spindle orientation board I know is for much smaller adjustments. Any help would be greatly appreciated.

I think it is # 4077

No such parameter on a om control. Its is a pot on the spindle drive. Should be 3 pots, one is coarse adjustment, medium, then fine. All three are in a row next to each other.

Parameters for OM-C spindle orientation 6531 and 6577 one is position and the other is a shift. I would try 6531 first. Don't forget to write down your original values if you have not yet backed up your parameters.

The parameters on this control jump from 820 to 7001. However I did get it orientated by loosening the sheave on the spindle and manually realigning. The fine adjustment I used R 11 I believe on the spindle orientation board.
