Fanuc 10T Backup battery life support

[zoeper]

Hi All,

I have a machine with a 10T controller that's been out of action for about 2 years now. The machine cannot be switched on now and i am dreading the day i get it back on and find the battery dead and the paramaters lost.
I know that the battary can be safely removed while the machine is under power, but at the moment that is not possible.
Is there a way to check power level of the battery without risk of data loss, and is there a way to tie in a second powersource (not neseceraly FANUC) to keep things ticking over in the meantime.

PS i do have a backup of the params on cd, but apparantly a param backup does not cover all the params??

Thanks in advance
Pieter

You can take the cover off the battery compartment to test the Voltage, make sure they do not pop out.
It is very important to have the 9000 options and 9000 programs and any counter timers.
But I guess if you do not have them, it is too late now.
If you can get access to the battery terminals and the ones in the compartment are borderline OK, you could temporarily connect a second source in parallel and then replace the C cells in the back up compartment.

Hi Al,

Just popped the cover off now and was actually surprized to find 3x D cells.
I was expecting a proprietry Fanuc battery costing $$$$

Must say after reading some of the other battery replacement procedures of pulling boards etc, fanuc scored some points in my book again.

now all i need to do is replace the battery in my multimeter (yes it was dead when i pulled it from it's cosy drawer) and hope for the best.

Thanks for the help.

Yes, I meant D cells not C.

OH NO!
-0.3V over the 3 cells
#1= 1.5v
#2= 0.9v
#3=-2v ??
all 3 have white powder on the - terminals.

The compartment lid have 2 screws securing it, and removing the lid reveals another 4 screws that seems to hold the battery compartment to the cabinet. Does anyone know if the compartment have wires fixed to it, or is it connected to a pc board or similar on the inside via springloaded terminals? In other words is it safe to remove from the outside to reveal the rear without braking contact?
The back of the battery compartment is not visible from the inside of the cabinet and i would like to make a safe connection somewhere to facilitate replacement of the batteries.

Also, what is contained in those parameters that you cannot bacup (8 or 9000's) and what can you do when they're lost?

Sounds to me like you have no battery back up anyway at this point. I seem to remember a cable coming from the compartment to the MB.
The option parameters are the option features purchased when the system was installed.
There is normally a Fanuc print out sheet.
The 9000 programs are such as Tool changer or probe routines etc.
It depends on whether the machine tool builder is still around and if he kept records.
Or find someone with an identical machine.

The machine is a Ajax-Victor TNS2 that was imported into South Africa late in it's life. I will find the backups and documentation i have of it to see what i have first.
Thanks for the help.

OK, I found those dusty backups of the parameters and i think also the lead screw compensation. Would anyone here be so kind as to have a look at the files and tell me if they contain the real thing?

Files attached.
Thank you
Pieter

Those look ok to me. You should just download the all.txt this contains all of your parameters. You will have to enter the option parameters in first by hand and then set up your communication settings before you can download via RS232. You will also need to get your Counters, timers, keeprelays in. This would be a hard copy as these parameters can’t be backed up via RS232.

Here is how you enter in your option parameters. You need to first convert your 9000 parameters to hexadecimal format. Looks like there is only a few for you. Let me know if you need me to convert them. I have a spreadsheet that I made to just plug the bit format in and it spits out the hexadecimal for me. Then use the following procedure:

Options
1 Power up machine with:
"-" minus sign depressed and
"." decimal point depressed
2 Key "99" and "Input"
4 Key in "2" or whatever # axes in parameter 9000 @ "AXIS" prompt
5 Step through options by # and key new Hexidecimal codes and "input"
Option 1 = 9100, Option 2 =9101 etc. Just "input" if no change req'd
6 If "clear files" appears, hit "Y" - will erase programs etc.
7 When 1st menu appears, key "6" and "enter"

I have also attached the cable guide and communication parameters.\

Good luck,
Stevo

Hi Steveo1,

Thank you for that information. I really thought i lost the 9000 param's. It seems like the leadscrew comp is blank anyway, so not much to that.
You say "You will also need to get your Counters, timers, keeprelays in. This would be a hard copy as these parameters can’t be backed up via RS232." I have got the wiring diagrams and what looks like ladder diagrams for this machine, but what am i looking for in terms of Counters, timers, keeprelays?
Thanks for all the info so far.

I have a Fanuc service sheet that explains how to load the 9000 para in a 10,11,12,15, using RS232.
Ironically, when you mention this method to Fanuc tech, they claim it cannot be done this way, or do not know about it?

Zoeper,
I have attached a blank PMC data sheet that I use to write down the PMC data. I have also attached my old written down PMC data for a HOMMA VTL with 10t control. Hope it helps.

Al,
I dont' remember if I got that procedure form you. I always went into IPL mode. If this can be done via RS232 it would be much faster. Can I shoot you a PM to get it from you?
