    Exclamation Haas error code 107 EMERGENCY OFF when spindle changes speed.

    Hello, having a problem with an older haas VFOE. New to me though. Maybe you guys can help.
    Getting error code 107 EMERGENCY OFF when spindle changes speed.

    Problem is NOT the counterbalance. I know because the error will clear with reset button and has same result when I jumper the sensor wire connector.

    Also it doesn't seem consistent as it will do this at various speeds. All at over about 2000rpm.
    Mostly higher speeds but sometimes it lets me get up to 4000rpm.

    Question is this: What components inside the haas have the ability to throw that particular code 107?

    Default

    what year machine? some with the delta/ wye option can cause voltage drop while shifting and cause a 107 condition. check ur voltages. the contacts could be going bad in either contactor. with power off check with a volt meter set it to ohms and push in the contractors, and measure resistance
