    Default Toolchange problem, Okuma MX-55VB OSP U-100M

    Can only change tool by manual ATC operation.

    Toolchange stops at toolchangecycle 9 of 29 and just stands there when i'm running a program in auto, or write T*** M6 in MDI.

    What can be the problem?

    The machine have be running for about two weeks without this problem

    1. error message MDI or auto mode
    2. diagnostics message
    3. Look at diagram - what are these steps? Is there curtain on Your machine between work area and tool magazine?

    Solved the problem.

    There was an endswitch under the cover that protects the toolchange system that was hanging. Cleaned it an moved it a little closer to the piece that activates it. All good

    take care. It's easiest way to move LS. Sensors are for detecting proper position of mechanism. First You must ensure if mechanism status is correct

    I don't know if i understand you correctly.

    The magazine is vartical with the tools situated horisontal out from the pots. When the tool swings down there is a little plate that touches the sensor when the tool is vertical and ready for toolchange. There is some delay from when the plate touches the switch and the actual toolswapping happens.

    It works like a charm now anyways

    that's correct. I just warned in case of another situation. Just pretend if tool pot doesn't comes to required vertical position and tool coming back to magazine hits the pot.
    My idea is to see the position of mechanism before moving limit switch.
    Inductive sensors are aging, of course. You can see hysteresis disappearance before sensor is totally useless.

    Sorry for resurrecting old thread, got similar problem on customers MX-55VA.
    Machine stops in automatic with this alarm:Alarm B 2354 Spindle orient position OFF, when changing tools from ATC.
    Also stop in sequence 9 in manual mode ATC.
    Solution: bad switch SQ8, Pot horizontal position confirmation limit switch.
    Oxidated, never dissengage electrically.
    Some contact cleaning and alarm gone.
    Check diagnose NO.28, input iPHOR, must gone when switch engaged.
