Controllogix SSV to change Absolute Feedback Offset Value

Currently I use an MRP (Motion Redefine Position) to adjust position. Is there an SSV where I can directly change the absolute feedback offset for an axis in a motion group? I've seen an article that references that it is available, but I haven't found how to do it. Any help would be appreciated.

Cheers!

what are you trying to do?

MRP is the correct way to do it - and is available during motion but not while a MAR on input 2 is active

I use MRP once on power up then do not need to touch it again
