Dear friends,

i have a fanuc M11, when i power on the machine on screen IPL MODE appears as below;

F11M9A 2040D
FBFB0008

SERVO ROM TEST :END
BUBBLE INITIALIZE :END
BUBBLE TYPE :03
BUBBLE PREPARATION :END
LOAD SYSTEM LABEL : END


IPL MODE
1 DUMP MEMORY

2 -

3 CLEAR FILE

4 BUBBLE

5 -

6 END IPL
?



when i enter 99 input then appear


SYSTEM GENERATE

CHECK SYSTEM LABEL :PASS

AXIS ?


I have not parameters backed up so that can be a problem;

Please tell me what to do next, without back up parameters

[memoryman]

There is no way for the machine to work properly without proper parameters. You have to answer the AXIS ? question and then enter the options in hexadecimal form.
Either the BMU is defective or the motherboard is.

Hi memoryman, thank you for your answer.
I answer the axis question (3).
Than write 6 (end ipl), and machine start work normaly.
But after 4 hours stopt, and on screen now write:
F11M9A 2040D
RAM PARITY ERROR
and lot of numbers.

Please help me, what I can do now?

Hi memoryman,

Now i have on screen lot of alarms No. from SV003 to SV015.
Tell me please whats going on?

You are missing parameters?

[duda]

Hi,
I dont know is parameters missing???????
On main screen I have positions, Tool offset, I can change the work programs, all work programs is steel in memory.
Mabe is missing parameters for servo?
What do you think?

[memoryman]

If you are sure that the parameters are ok, than look for a blown fuse, tripped overload or another machine interlock problem.
