Fanuc OM Program Execution

[Camber]

Hi all,
I have just purchased a Leadwell VMC with a Fanuc OM control. I have got the dnc communication working from my PC, I can select & edit programs OK, however I cannot workout how to put the program into Auto mode and execute via cycle start.

Any assistance would be appreciated.

Thanks

Select AUTO mode, select the program by typing in Oxxxx program number and press cycle start.
Do you not have the manuals?

Hi Al,

I tried what you said, (auto) mode, program # o0005, (input), the lsk text at the bottom of the screen flashes continuously but no program is shown and wont cycle start. It does have the program number in the top right corner of the screen though. I do have the manuals but are vague at best.

Thanks

In AUTO mode, PROG function, key-in the program number, i.e.: O0005 then press the cursor down key. You should then see the program in the display. Press Cycle Start. Don't use INPUT.

Hi dcoupar,

I tried what you described...no luck. I did manage to execute a program last night and cut metal . I noticed when cycle start was pressed the LSK letters flashed so guessed it was looking for something through DNC. I sent a program fom the PC DNC then cycle start, hey presto the program from the PC executed. Does this mean it would be drip feeding or has the PC sent the whole program?

I am guessing the Fanuc control has been previously configured to only accept DNC programs for execution. It would be nice to be able to run from Fanuc memory though.

Another question (hope I'm not pushing my luck!), I had to remove the Z axis servo motor to get the machine in my workshop, the MTB manual said I have to check the Z axis home position in relation to the ATC otherwise it could damge the ATC. Using a straight edge, I checked the clearances from the tool to the ATC and they are out by about 2mm. So I need to reset the home position up 2mm. Quote from manual "Set the correct position value (from display of CRT) to parameter NO.510 Z axis".

Parameter 510 currently reads -900, would this value mean -9mm, ie I would need to input -700 to come up 2mm on the home position? Also, nowhere in the manuals can I find how the alter the parameter settings and I have tried just about everything to change these values.

Sorry for the long winded reply,

I appreciate everyones help.

With mode in MDI, turn on "parameter write enable", also don't forget to turn it off when you are done.

This value is the grid shift in basic encoder resolution counts.

You have used illegal variable number.
For example, use of #35 would throw this alarm.

Common variables #990 & #991 are only available if the extended variables option is on. You might try replacing #990 with #100 and #991 with #101 in the macro.

Some problem in this part also:
...
IF[#4120LT17]GOTO10
M92
#3000=1
GOTO500
N10
...

After the macro alarm, GOTO 500 would never be executed.
