    Fanuc A axis issues

    Hello.
    I have a Doosan DNM400 with a Fanuc oi-M Model D control.
    Just put a rotary indexer on (A axis). Having some issues with it running correctly.
    Sample Code:
    %
    O0246
    N5 G00 G17 G20 G40 G80 G90
    N10 G91 G28 Z0.
    N15 T1 M06
    N30 M08
    N35 G00 G90 G54 A0. X.109 Y-.5917 S4000 M03
    N40 G43 H1 Z1.
    N45 G94
    N50 G98 G81 Z-.635 R-.2 F1.
    N55 G80
    N60 G91 G28 Z0.
    N62 G91 G28 X0. Y0. A0.
    N65 G00 G90 G54 A120. X.109 Y-.5917
    N70 G43 H1 Z1.
    N75 G98 G81 Z-.635 R-.2 F1.
    N80 G80

    When the program reached line N60 it went to Z home position then gave a PS0224 Zero Return Not Finished alarm. I added line N62 and then it went to all axis home positions and sat there for a minute (spindle running) then on to next move (line N65. It was supposed to rotate to A120. but went to A280.800 Is there a parameter setting for the A axis I need to change for this to work correctly? I don't understand why I need to send it to machine reference position for it to even run without alarming out? When I run 3 axis programs, it runs fine without all the reference return moves. Thanks for any and all help.

    ...this sounds like A axis is inverted or needs to be. There probably is a jumper or dip switch on the axis drive board for reverse operation.

    Got it figured out. I feel dumb now lol.
    Apparently the power was shut off and the a axis was never zero returned.
