Need Help!- Battery change and initializing position _ NL series

[aidenkim]

I need help ~

i have a NL series machine and it's battery for NC,SERVO parts was down,
so i changed it and resetting the absolute position (X,Y,Z) yesterday

however, when I try to set for 'T' axis today, the problem is that i can not change the status of ZERO POINT SET to 'VALID'

when I try to change it to 'VALID', the message 'zero point set is already done' is issued, even T axis doesn't set before

please let me know the way to change ZERO POINT SET to 'VALID'
or the way to set T axis ~

if the battery died and you lost all of the parameters you're going to need a Fanuc service man to visit you to re-install everything.
That's all part of the protection on Fanuc systems and why there are so many undocumented parameters. If you have option boards installed like 4th Axis etc then there's no way to get it working without having the secret option parameters. If you don't have a back-up there's no way to fix it yourself.
If you have the parameter manual you should be able to re-set most of it and get it mostly working but it'll never be 100% without a Fanuc service guy to do the secret stuff.

This machine comes with Mitsubishi NC. I think best you contact local rep to resolve your turret (T) zeroing issue.
