Fanuc 6T system error

[salmve]

Hello
I purchaced old Nakamura TMC-3 with Fanuc 6t(b). It was out of order, so i get it at resonable price. I wired it up and turn mainswitch with shaking hands. All i get was "SYSTEM ERROR 9*" *-mark is strange symbol, looks like Japanese letter. Led number 1 lit on (master PCB) I have maintenence manual for this (Thanks Jonne) and i found out that it means alarm number 600. Maintenance manual has no remarks for this alarm.

I have read old post and found out that maybe i have to do some cleaning. First i will clean part programs, and then parameter data, and last totally cleanin of bubble memory. I have instructions for those. Is that right way? I think it is better to ask before than do something stupid, isn't it?

I have paper named "Setting of parameters" made by Nakamura. There is parameter numbers and data 0 to 160, 1001 to 1018, 2001, 2002 2101, 2102, and 3001 to 3004. Is that enough to get machine running if clening procedure get alarm away?

In the tape reader was tape without any marks what it is. Could it be machine parameter? But what a shame it is in two! But maybe it can repair and get reading.

Thanks in advance

Your "setting of parameters" is enough to get your machine running,the parameter 0 to 160 for machine running ,1000's,2000's,3000's are for pitch error compensation of X,Y,Z axis ball screws.About the alarm 900's (you don't write down exact the alarm number) i think you have to perform a Ram test or Initialize the buble memory to clear the alarm
The punched tape on tape reader, if the original parameter tape from Fanuc it's usually have the label "parameter tape" on the leading of the punched tape.In your case I think it's may be a machining program tape

Thanks duccnc.
Is that bad sign that i cannot get exact alarm code? As i wrote above i get message: SYSTEM ERROR 9 and beside number 9 is strange symbol.

Today I have tried:
"clearing stored program", RESET+DELETE+Power on: no response
"clearing parameter",CAN+DELETE+Power on(Param Switch Enable): no response
"bubble memory all clear", 0+DELETE+Power on(Param Switch Enable): no response

When i did "bubble memory initialization procedure" ,-+.+Power on(Param Switch Enable) I get IL-mode but only three choices!
1.Tape
2.Memory
3.Enpane

What can i do next?

BTW quote from Dan Fritz:
"FYI: This procedure is fully described in the 6T/6M Maintenance manual"
My Maintenance manual number is B52245E/01 But i did not found that

When you initialize the buble memory you must switch "BMU switch " to ON position (NOT the parameter SW to enable) it's on upper side of the master print.

[salmve]

Thought it ask me to switch it to on position after hitting number key (1-6). And i tried also with param. switch in disable position.

Now I have tried all combination (Param switch enable/disable, BMU switch on/off) and every time i get only three choices.

What next?

hi all,
just called me as shimi. i'm still new in this forum. i have TSUGAMI Model S16 Precision CNC Automatic Lathe. it use FANUC system. yesterday i was off the main swictch board for service and calibration. and also switch off the main switch of the machine. after finish the service, i switch on the machine and i got a lot of error on the screen. why it became like that.

i also don't know where the battery. can somebody help me ASAP.

After you initialize bubble memory ,you must depress key 4(bubble )to enter the screen:
Bubble initialize
*function key
1:write by tape
2:write by manual
3:display loop data
origine :return to IL mode
you must press key 2 (after switch BMU SW to ON)to input the defect loop to enter the defect loop data as Dan Fritz quote.

What 's Fanuc controller? I think you have to re- input the option parameter

When i have IL-Mode on the screen number 4 does not give any response!

Only 3 choices with one working. Number 1.Tape; It opens "IL-MODE READ" screen but nothing happend because i have no tape.
RESET exit from IL-MODE

What i am doing wrong?

salmve: You probably have an older version of the Fanuc 6T (the 6T-A). The earlier versions had the limited IL mode that you describe, and the repair of the bubble board is not possible by manual data input. You may have to put that bubble board into a newer control to initialize it, or you may have to send it to Fanuc for re-initialization.

To verify what model you have: Do you have a bunch of EPROM chips (with labels on them) on the large main PCB? If you do, look at the numbers on them and get the first 3 digits. That will tell us what edition you have. All the EPROMs should have numbers where the first 3 digits are the same. The last letter will tell us what revision your firmware is. EPROMs on the main board indicate that it's a 6T-A

If you have all the EPROMs on a smaller board marked "ROM", then it's a 6T-B. Again, the first three digits and the last letter will identify the firmware edition and version. If those EPROMs are 32k-bit (identified by the last digits of the manufacturer's number stamped on the EPROMS, then it's an early 6T-B. If those EPROMs are 64k, then you have a 6T-B-2 or "level up"

My guess is that you have a 6T-A because of the 3 choice IL mode menu.

I'll help you further if I can.
