Problem with Fanuc 11M Bubble memory initialization
Hello your help is needed.
Problem in initializing Bubble memory with Fanuc 11m,
Due to frequent BUS ERROR and intermittent stop of the machine while running I cleared memory by pressing 7 and 9 button while switch on.
After this, following screen Displayed.
I tried to do several time BUBBLE initialize by pressing 4 followed by 2 (for initialize). It ask for Defect Loop Number?
(I hade selected free mode switch to service mode in Master PCB)
To check the Defect loop Number in IPL MODE, if I press 4 followed by 3(display defect loop) it gives following display.
BLOCK#:1A
READ MAP : TOO MANY DEFECT LOOPS.
Or
Some time it display
NOT READY.
Due to this, initializing not taking place. Also I am not able to put the option parameters. And other parameters.
I request is any other method for initialize bubble memory……..? or this could be hardware problem…..?
tou may have to reformat the BMU .Defect loop data is on the BMU itself.
Call me if you need help.

Ok, Bill, I'll have to try that next time I encounter this problem.
I have seen several of these modules on eBay. I would like to upgrade my 11M sometime and would like to know which part numbers to look for and what they are.
One of these 3 possibilities:
1: powers supply voltages; +5V must be at least 4.75V
2: bad BMU (re-initialise and/or replace); all memory is lost; see maintenance about how to re-initialise
3: bad motherboard
#2 is the most likely.
Re: Problem with Fanuc 11M Bubble memory initialization
Anytime I see that screen, Ive had to reload all the parameters. Fortunately, I have a good back. I have 2 machines with the 11M. Happens about every other year or so. If you dont know what your doing though, Id pay someone whose qualified. It can effect your options on the machine too, which is another reason to hire someone. It will take less than hour.
