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.

ROM TEST: END
RAM TEST:END
BUBBLE INITIALISE:END
BUBBLE TYPE:03
BUBBLE PREPERATION :ERROR
0014 E180 0000
IPL
1.DUMP MEMORY
2-
3.CLEAR FILE
4.BUBBLE
5.-
6END IPL

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…..?

Please help to resolve the problem.


Thanks in advance…
