problem: parameter issues yasn

I have a matsuura 500 with a yasnac mx2 controller. The parameters were recently wiped from the system and I have entered them all back in. The problem is, the unit is essentially "lost" in position. I can't get any of the axes to home because it won't read the limits.

i know this is a parameter issue, but I can't seem to get it. Has anyone else had this happen to them before and have a easy fix for this?

Probably better to ask this in a forum for a Matsuura or Yasnac.
