Mach4 General Discussion / Fanuc A20B-005-0374 DC spindle board wiring & settings
« on: April 16, 2021, 02:44:15 PM »
Good afternoon,
Could I ask for some guidance on what pins to use on the FANUC DC Spindle board that is on My old SL-3B lathe?
the lathe I purchased came with zero technical documentation and I have been trying to identify wire by wire on the harnesses what is connected but not having worked on anything FANUC I am starting from scratch. Next question also is jumper settings if the board is not set up for analog reference input. Somewhere I thought I saw on forums that some of these boards are feed a serial command for speed reference but I could be mistaken.
I will be using a Vital Systems DSPMC for the spindle control analog signal.
Thanks in advance for any help.
Brian
