Hello Dear,

We have a Fanuc 0-t series controller. Recently, there is a problem with CNC loading. After the switch on the machine, there is wrong data on the screen.
I have checked the CRT monitor and it's ok.
Please see the attached file.

best regards

You may need to reload the Parameters.
If that doesnt help it could be either the
Graphics Memory card (CCX4) or the
Machine Memory card (CCX5)

Best wishes, TJ

Hi TJ,
Thanks for your reply.

Actually, I solved the problem. But now there is a new problem. All parameters and parameters have removed.
I emailed MTB company but they don't support this machine anymore.

Do you know any other way to reload the programs and parameters?
Also there is a Macro Cassette B on the main printed circuit board and maybe the backup file in it.
Do you have any information on how load program from the Memory cassette B?

And also may you have access the backup of this machine?

Machine no: Ge Fong, Swiss type lathe, GNT-1712
controller: Fanuc o-t series

Best regards

I am a CNC "board level repair" depot so I am not all that familiar with operation and programing
but the Manuals will list all the Generac Parameters to get it running.
There should be a Parameter list that came with the Machine also.
Sometimes in a pocket on the inside of the Control door on some machines.
The Part Programs I am not sure about the Cassette. Send your inquirey to...

Wishing you good luck, TJ.

I found the backup parameters and I entered them manually and all alarms have solved.
But now the CNC got stuck at MDI mode and can't change mode by the selector. Because of this problem, I couldn't be connected by serial connection and had to set parameters manually.
What's your idea about changing the mode problem? Is there any PMC flag in the ladder program associated with the mode selector?
On the diagnostic page when change the mode selector, X000 bits changed.

I do not see the display photo.
The cassette has nothing to do with the parameters or part programs.
Do you have any backup files?

The mode defaulted to mdi because you likely lost the diagnostics (pmc params) and will have to reenter them .
