    Fagor 8040-T alarm: 40. please change gear to L

    Dear CNC experts,
    i am facing a problem.
    When I try to run the machine on Automatic Mode then i am getting a alarm: 40. please change gear to L

    I am not getting any information about this alarm. How can I solve the problem?

    In Jog Mode you should see the M41/M42/M43/M44 is active. Gear L means low gear. It seems none of the gears are active and the spindle is out of gear.
    There must be a way to change the gear manually in your machine. You need to change it to low gear.
    If it is already in Gear one then there must be a gear confirmation switch that is not working.
