Hi - I am trying to find out about integrating a 4th axis on Leblond Makino FNC mill with Fanuc OMD control. 1989 vintage. Tried a 4th axis with a fanuc motor A06B-0128-B575#7008 and it would not read the encoder. I think I need to find a different motor like what is on the x axis of the machine A06B-0502-B002#7000. these are different encoder types yes? Where can I find compatability listings for fanuc motors and drives?
