Hello!
I have problem with Nakamura TMC-4 Fanuc 6T (-80) spindleunit. If I start spindle it only crawl same direction. MDI, JOG, program or manual start, same result.
There is tested new spindle unit, new I/O-cards, everything except new mother board, but I don't think that is problem.
Maybe this is tacho problem? Use this A20B-0008-xxxx spindle unit digital tacho or analog?
Anyone have same problem before?
