    Okuma Millac 800VH - 15818 "APC A position not complete".

    Below is a small description of the problem:

    The machine model is Okuma Millac 800VH

    The equipment failure is that when you want to change pallet M60 and automatic does not perform the sequence and in Manual mode, it does not advance to sequence and shows the diagnostic 15818 "APC A position not complete".

    In the APC sequence parameters it allows us to advance to stage 3. In number 4 (where the pallet goes up) the UP pallet output does not activate.
    Note 1: A sequence step does not execute the movement of the axes to home.
    Note 2: The original fault sent a Stroke over end alarm ¨ which was reset. No axis was moved or new origin was set.

    hi, far as i see, you can't reach the home, and there was an error about over stroke; this happens when the encoder slips, there is be a friction part, but also there may be other causes ... i would verify that the phisical travels and origins are where they should be, and after that the alignment, in respect to apc & atc

    what axis caused the over stroke, and why ? kindly

    I have had issues with APC no completing the cycle
    .... Rapid override set to zero
    .... spindle toolclamp in open condition ( or in-cycle )
