FANUC om control, Supermax Max1 "machine 0"

Andrewdini · May 6, 2019

hi, new to forum. also supermax max1 with fanuc om control. lost z-axis "machine" 0 and its shows about +34.627 above where it should be. would I adjust the 702 parameter lower? my machine was running fine before. lost zero return due to hand feeding too aggressively one time, now would go past machine 0(using zero return button). got stuck at top of z,pryed axis free, reset, then lost "machine" 0.

mine currently.
N0700 P 00000500
N0701 P 00000500
N0702 P 00000500
N0703 P 00000000
N0704 P-00600500
N0705 P-00400500
N0706 P-00460500
N0707 P 00000000

NO820 0
NO821 0
NO822 -00034627

or can i just change 822 to 0?

Try zero return and then shutting off your machine and on start-up hold down P and Can (P cancel). Should return your position to zero. Had to do that a few times my self. May sure your are a slowest feed upon start-up.

Agreed! The P cancel trick is the default go to in this situation.
