I am installing an old 18tb on a vtl. It was previously a 4 axes and now is a two axes. The problem is that it will not jog even though every interlock and signal is satisfied. Fanuc cannot illuminate what the problem is, so, I found out myself. It seems that the small cards that populate the main board have something to do with it. Unfortunately, I had erased the system software and had to load a new one from a two axis system. (remember it started as a 4 axes). Everything seems to work fine except that it will not jog. It will however move in a program. Anyone have experience with this. I am wondering if there is a card that specifically deals with the servo software? I found the cards that interface the CRT and MDI panel. I found the PMC card. I am wondering if the FSRM card might be the servo system. Any ideas? Thanks.(chair)http://www.cnczone.com/forums/images...withstupid.gif
