310 APC Alarm

[MazakMack]

We have alarm 310 APC Alarm:X axis need ZRN on a Takisawa lathe.We had a broken wire going to the servo, fix that and now have this alarm.Machine will not go to X reference point.Its like it lost its reference point in X axis.Z axis is fine.is there a way to reset this point??If I need to change parameters, where can I get them?
thanks for any help!!
