    Miyano BNC12S Parameters

    I just Bough a Miyano BNC12S Fanuc OT and the B axis doesn't do what I tell it to do
    it doesn't
    like the G110 (if I can Only able to use this that will solve all my problems) command or the G102 or G103
    The G101 it reads but only 2 or 3 lines and it ends the canned cycle
    please if some one can help me out with the parameters
    thank you in advance

    Did you get a copy of the parameters ?
    I am looking for the electrical diagrams for this machine. I can send you a copy of the ladder diagram.
    It has no address descriptions.

    the Miyanos that use the 0T control and the g110 are a super pain in the butt.
    If you have the manuals, they do not behave exactly as they describe. The g101 behaves in a unpredictable manner for me and i wont use it.
    you have to have
    G110 T71 or whatever you are using for the b offset, on the first line
    then
    G110 Bx on the next line
    this is moving away from B ref return pos. The workholding must be open to move in the B- direction.
