Good morning
when I power on the CNC FANUC 15 MA machine I got this messages on the screen and the machine freeze:
--------------------------
Slot configuration
0: 431E00
1: 012502
2: C11D01
3:
4: 022204 Ram Parity
--------------------------
The figure bellow represents the boards led status after powering on:


 
And I did the following:
- I turn the power on while pressing ( 7 + 9 ) keys, to clear all memory but nothing happened.
- I have already copied all the EPROM programs years before the machine breakdown, so I verify all the EPROM programs and they are ok, the EPROMs are the following:
o Board P22 (Graphic CPU) : [6082/001A] + [600B/001D] + [600B/002D]
o Board P1E (Base0) : [6081/001A]
o Board P1D (Base1) : [A002/081T] + [A002/082T] + [A002/0C1T] + [A002/OC2T] + [A002/101T] + [A002/102T] + [4040/001N] + [4040/002N] + [9030/001Q]
- I check the power supply and it’s working fine [+5V, +15V, -15V, +25V]
- I check the battery and it’s working fine [+4.5V]
- I don’t have the maintenance manual for FANUC series 15MA
Please guide me to a solution to operate back the machine.
Thanks in advance
