Fanuc 10T system label error

[Andy Fritz]

After replacing lots of memory the problem remained. The solution that finally fixed the problem was to run the machine with wide open doors to the control cabinet and placing an industrial fan blowing on the control pcb!

On the a16b-1010-0040 motherboard, the diagram show the 6264 chips in positions A34 & B34 to be connected to VCC, while the other sram chips are connected to VBB!
All of the sram chips on the -0380/1 board are connected to VCC, so they cannot be for part program storage.

By any chance do you have a schematic for a system 10 -0321? having issues with LED showing "8" after memory parity error and no video on screen, suspecting memory reading circuit failure.


Good Day.

Fixed, after swaping BAC and FXA chips on motherboard from a "damaged" board.
