Guys,

I got this terriblle "101 alarm" on my Fanuc O-MD this morning. I read the maintenance manual, an it requires me to delete all memory.

My problem is, if I delete all the memory, I won't be able to retrieve the special program or protected program (some call them PRC and I don't have a clue ?) already in that controller. The reason is, I don't have any back up for those program.

Fortunately I had back up on my other machine which is using Fanuc Oi-MB. The problem is, the machine are different.

Below are the program that i mention which is on Fanuc Oi-MB (Machine Twinhorn VA 500).

I'm afraid to use this program on Fanuc O-MD because I'm not the one who wrote the program. Is it ok if I use this program? I know the purpose of each program. I'ts just I'm not sure to use it. Is there anybody know anything about this?

The machine with this problem is FEELER FV-1000ASE and Fanuc O-MD controller.

Attached are sample of program which I normally use.

Thanks in advance.

Can you enter edit parameter mode.

[mrsammy]

yes i can, but if i delete it all, i could not retrieve it i guess.

[PTtec]

the 90xx's programs are macros from machine manufactor, you can not use from other machine. if you can enter in parameters maybe you are able to make backups of macros, parameters, pinch tables, etc.. by your dnc line to a computer!?

[MachMan]

My Fanuc manual says:
Alarm 101
"The power turned off while rewriting the memory by program edit operation.
If this alarm has occurred, press <RESET> while pressing <PROG>, and ONLY
the program being edited will be deleted. Register the deleted program."

Programs that start with 9000 are difficult to erase because they are
write protected, special macros (small programs or routines). They are
usually called by other programs and then return to the main program.

You should be able to copy them to a floppy disk and reinstall after.

I don't know wich fanuc manual you have but in my FANUC O-MD manual there is no mention about this procedure. But if it works it would be nice!

This macro don't seem to be from machine manufacturor and syntax seems to be compatible with a O-MD. If you have good understanding of custom macro B and you have time to test it, i think you can try to transfer it without to much risk. But probably you also have a macro for your tool change if you have automatic tool changer, and this macro is made expressivly for one machine tool and cannot be transfered from a machine to another one. May be the machine tool builder can help you for that or if you also understand ladder you can check it to find tool change macro logic an re-write your tool change macro. I can give you mine, except custom M code it should be very similar to your.

On my experience, on a O-MD you cannot use your DNC line when there is an alarm nor to call a program to see it. So i think it's to late to do a backup.

mrsammy,
If your machine is powered on and everything is displayed then just make a backup of all your programs from the control. You will have to activate PWE and unlock your 8000 and 9000 programs using your parameters.
I am not 100% but I believe that on the O-md control that to enable the parameters it is the 2nd screen from your offsets, using the offset key. It should say parameter write enable. To unlock your 8 and 9000 programs it is parameter 3202 bit 0 for the 8000's and bit 4 for the 9000's. Set them equal to 1. You should then beable to download all of your programs via RS232 or memory card.

some DNC's you can backup when there is an alarm. If yours can not then as Samu said it is to late.

However some of the macros you might not be using. I delete most of mine from the manufacture and write my own. Check to see what ones you are using and write down the most critical ones.

Thanks for your info Stevo, I manage it already through PWE enable. It was on parameter no 10 and it was something like 00000010. Honestly I didn't have any formal training on CNC, but with the help from good people like you all I am grateful.

Once again, thank you.

[stevo1]

Your more then welcome. I am glad that everything worked out. Don't hesitate if you have anymore problems, questions or need documentation.

Best of luck,
Stevo
