WorkShift problem

[Tancuda]

Hi all,

My control is a 21i Tb on a cylindrical grinder.

When I go to the workshift page, on the right side under
MEASUREMENT, and just next to the Z I type 0 and press INPUT,
my Z become 0, that is good, but as soon as I hit reset the Z change back
to what it was before !

Any parameter for that ?
Did try 1201 #7 and 1202 #3 with no luck.

Thanks a lot

That should not happen.
Did it always do that or has it just started doing it?
There are no common parameters for that but perhaps you are missing an option parameter(such as Direct Input Measurement or Workshifts G54-G59)
Try inputting a number on the SHIFT VALUE instead.

It sounds like you have the crappy workshift option like 0-T without proper workshifts (G54-G59).
Can you post a pic of your workshift screen here, maybe there is something else missing.

If all else fails you can use G50 X..... Z...... in the program.

Thanks for your response.

The machine is 1 year old, and I just started to work on it, so I believe
the problem was there since day one. It's the same thing when inputting a number
in the SHIFT VALUE. II'l try for the screen shot. You said that I probably have the crappy workshift option like 0-T without proper workshifts (G54-G59), but I have the screen for offset G54 to G59. So if it's an option, I'll talk to my boss to get that option.
Thanks

If you have G54-G59 there should be a proper page to set the Z0 workshift not just measurement and shift value. Even without it, it should work.... it's like 0-T.
See the attached workshift page from my 21iTA
The G54 is also COMMON/EXT and can be used to set the Z0 even if not using G54/55/56 etc
1st pic is standard Fanuc version. 2nd pic is the nicer Mori MAPPS version.

to set Z0 put cursor on EXT Z, type Z0 then press MEASUR. The number stays there always until changed. Reset has no effect on workshift.

just a thought... you have G54-G59 page so just leave the other workshift values at 0 and put your shift amount in G54 then put a G54 at the top of the program......

The G54 method worked, and I will try the EXT Z also.
For this machine there's a way to do it, but I have to switch in conversationnal mode, and click on a few keys to get there so that's
why I was looking for another way of doing it.

Thanks
