Hello All..

I m writing in Turkey. I have a Nakamura TW20 with Fanuc 16TTA

I have problem about the machine is not opening.

First Alarm was 900 Rom Parity CNC ROM Modüle F81

After this alarm we start to check the Rom card on Main Board. I think we fix that after buy a new rom card and install the software.

Now machine is not opening. On the screen there is B103 - 25 Slot2-3-4 End Not Ready

But When we take out the OPT2 Card (in the attachment) Machine is opening but there is nothing we can do.

Sorry for bad english

What is the problem what can we do for this problem?

Thank You for all
