    Fanuc O-TT Alarm: 522 OVER TRAVEL : +Z

    Hey All,

    I have a SST-16 Swiss Lathe Machine with Fanuc O-TT. My sub-spindle suddenly stopped working and this alarm message appear : 522 OVER TRAVEL : +Z.
    When I use JOG, It moves backward until it reaches the end. But when I try to move it forward, It moves for like 1/16th of an inch (1 mm) then the alarm message appear : 522 OVER TRAVEL : +Z
    The parameters are the same. I have no idea what is happening.

    It sounds like your SST-16 Swiss Lathe is having a limit switch issue or there's an obstruction causing the sub-spindle to think it's over-traveling.
