fanuc 16m ext offset

[shredder]

Does anyone know what parameter I need to change to get my 16m g54 ext offset
to stop zeroing on startup,I would like to be able to store offsets there and not have it go back to zero on startup?
thanks

I believe it's #1201 bit 2 (see attached).

thank you for your help,I will try this and tell ya if it works.
thanx again

I tried this and it still goes back to zero on reboot?

What do you mean by G54 ext offset?
Ext offset, G54 offset, G55 offset ... all are different.
Do you mean geom/wear offsets which are normally cleared by RESET?

I mean the ext offset clears to zero on reboot

You mean this one, correct?

Ext offset clearing to zero upon reset is unexpected. There might be a parameter setting which I am not aware of.

ANyone?????

I've run out of places to look for the solution to your problem.

For now, you could add a couple of blocks at the beginning of the program to "preset" the EXT offsets:

%
O1234
G10 L2 P0 X-12.3456 (X-EXT VALUE)
G10 L2 P0 Y-2.3456 (Y-EXT VALUE)

Better still, set ext offset to zero and repeat the work-offset-setting process (or, if the ext offset values are known to you, just increment/decrement the G54 (etc) offset values by those values). Do you really need to use ext offsets?
