Fanuc Servo Amplifier, could I swap with this?

    Good morning all,


    I have a motor (A06B-0142-B075) powered by servo amplifier (A06B-6079-H105). I am receiving fault 8 (high current fault) and need to swap out drives after confirming that power cable & motor are good with megger. Could I replace the A06B-6079-H105 with A06B-6079-H106?


    Fanuc CNC service did not recommend; they said H106 outputs more current, but my understanding is the drive will only output as much current as the motor itself draws? So if my motor is the same, and I replace it with H106, my theory is it should run, but now my drive can output more power / current if required.


    Is my understanding above correct or should I play it safe and just order the correct servo amplifier? Thank you!

    I would say don’t do it as you risk damaging the servo motor which is set up to run off a certain AMP with a certain current output.
