Hardinge CHNC II+ FANUC 10TF LSI OVERFLOW ERROR

Does anyone know much about the Hardinge CHNC II+ with FANUC 10TF controller?

We are getting a “SV011 x LSI OVERFLOW” error. I have had a Hardinge tech come out and find nothing wrong with the AC servo drives (It had the DC to AC drive conversion). FANUC says to double check my parameters since I think someone came in and changed them to factory original at one point. I am wondering if this could be part of the problem. Maybe the parameters are set for the original machine without the ac drive conversion.

When I told FANUC tech suuport about the error above, they said that it could be the Axis Controller board, or the Motherboard that is faulty.

I am able to jog it manually at a slow speed but when I run a program that has G00 rapid traverse is when it will throw the error. I did get through a whole program when I selected the dry run mode (super slow).

Any help would be greatly appreciated.

Thank you
