Sinumerik 3T 6FC 3131-0FA-Z

Hello everyone,

I find this forum while I was 'Googling' for some schemas ... nice informations can be found here :)

I have some problem and I hope that some of You can help me. I have some old CNC machine (GUDEL-G50) with Siemens Sinumerik 3T ... and some erorr there. Because of that I need schema of Siemens Sinumerik 3T -> '6FC 3131-0FA-Z' board, that I can found where is the error.

Are there somebody that have some schemas or specifications for this model ?

Thanks,
Ivan
