Hello, my name is Salvador and I am from Mexico, I am new in the forum, I work as a maintenance engineer in a Japanese company.


I have a problem with Yasda YB-850V year 1995 Fanuc 15MA control.

When I turn it on for the first time, the following message appears:
F15M14
SYSTE ALARM
02: 5139: 01: 4045: 0011: 0094H581
NMI ERROR (00185C): PC040

After stay on for a while and restart appears the following message:
M15M14 AA2RA
ROMTEST: END
RAM TEST: END
SUB CPU RAM TEST: END
SERVO ROM TEST: EDN
SLOT06 (015C):

The A16B-2200-0521 BASE0 card has the red LED number three on. (I haven't found the manual, so I don't know what the red LED on means).

I have removed the card A16B-2200-0521 BASE0 and I suppose that the parameters have been erased, although before removing it I already had the previous message.

I have tried to send the parameters again but when pressing keys 7 and 9 the machine does nothing and gives me no option.

In Mexico it is expensive and difficult to get the A16B-2200-0521 BASE0 card, so first I would like to know your opinions.

I hope you can help me!!!

Regards!!

I solved the problem.

1.- The problem was not the Base 0 board
2.- Slot 6: referred to the RISC CPU board (it was damaged)
3.- Fanuc quoted the RISC card at 25,000 USD (a lot of money)
4.- A service company gave me the option to deactivate it (I chganged some parameters)
5.- I removed the board but machine blocked at the beginning (it was a short circuit in a Relay)(SLC error 84 (00):PC050 alarm)
6.- I changed Relay, I sent parameters and it worked perfectly.
