hi guys
im running on Fanuc 0mc. i recently got a ps101 alarm on my machine which forced me to do a memory wipe and reinstall the programs, which i did.
when i went to do a test run the program wont run properly. it stops on the M06 tool change command with error code ps78 (number not found). now im totally new to all this so dont know a lot but ive done a bit research and im being told my o9000 series programs have been deleted and need to be reinstalled. is this right? i dont seem to have any of these backed up. am i able to write a new program in its place?
any help would be much appreciated

Yes you are correct. M06 on your machine calls up a "Macro" O9xxx to move the axis into their correct location and the swapping of tools take place. As far as how the O9xxx program was written all depends on a lot of factors. Typically the machine tool builder writes these. Many machines also have more than 1 O9xxx programs installed. You might also be missing the O8xxx programs as well. I would try to get a hold of the machine tool builder for these programs. Also, I would make a complete backup of your machine before you end up loosing everything.

Meanwhile, you may try to look for a parameter which stores 6. If you replace it by 0, then M06 in a program would work in the usual manner (would not call a sub)..

[drdos]

Parameters 230 thru 239 & Parameters 240 thru 242. If any of these contain a 6 then make it zero so the M06 code won't try to call the O9xxx program. Just keep in mind that you will have to move the axis over to the tool change position first. Sometimes this is done by G30 X0 Y0 Z0 in the program. Check parameters 735 thru 711 for the 2nd reference position

Thanks guys I'll try this Monday morning when I'm back at work

[lee-gib]

ok ive changed the parameters to equal zero and it now works fine, thanks for the help.
unfortunately i have another problem, the M60 APC code doesnt seem to be working. the program reaches M60 and freezes with the cycle start button staying green but no alarm codes

[drdos]

Sounds like the axis are not in the correct location to do the pallet change. Did you try the G30 X0 Y0 Z0 before M60? Maybe have to be at G91 G28 X0 Y0 Z0

Parameters 230 thru 239 & Parameters 240 thru 242.---was any of these 60?????
if yes you need to put it back and you will need the APC macro program for changing the pallets.
