    Fanuc 18M : Spindle-1 Alarm detect (AL-31)

    Dear CNC Expert,
    I have a machine Fanuc 18MC. Initially the machine shows an error; AL-27 Position coder signal disconnection
    We have changed the encoder of Spindle motor.
    Now, new alarm came: 751 Spindle-1 Alarm detect (AL-31)

    Can anyone help how can I solve this problem?
