    Fanuc spindle drive trouble

    Spindle drive gives alarm 2 going from 2000 to 3000 rpm and dosn't sound right , sounds lower in pitch when running. Drive is A06b-6044-H007 and motor is A06b-1003-B100. Dosn't blow any fuses. From search this is feedback related alarm. Need help diag pulse coder or PCB.
    Thanks Drew
