Sure hoping someone can help. I have a Tsugami NP20 that had to have the Sub CPU board replaced. I downloaded the Parameter for the Fanuc Controls and the Diagnostic Code (What is now the ladder) on the machine side. Everything is working... except the C-Axis Interlock. I am guessing the is a timer that can be set to give the axis time to orient and lock before the machine gives and alarm. I have a stack of books that came with the machine... but, nothing that tells what the machine side (Tsugami) Diagnostic codes are. Does anyone have any knowledge of this... or a list of what the codes are. I am guessing this is a code that is skipped over when the Diagnostic side is uploaded. Thanks Mark.
