    Fanuc Servo Amp /Motor settings Help

    I have an alpha motor part number a22/2000 running on servo amp part number A06B-6079-H208 and both axis work fine I can run them forwards and backwards.


    When I connect a A06B-6079-H106 amplifier with the same parameters and motor and the motor does this (see video) any ideas?

    At this point I am not even trying to run the motor it is in holding torque waiting for a command. I have set servo parameters to be correct for that motor (20 in the servo parameter page).

    Can anyone help?

    From the Fanuc manual the A06B-6079-H208 is specified 80/80 and the equivalent for one axis is A06B-6079-H105.
    So, inside the amplifier the firing board is diferent in electronic components that has the -H106

    thanks for replying - so is it not possible to get an a22/2000 to work on this A06B-6079-H106? ie it will never work?

    A06B-6079-H106 amplifier works fine with a22/2000 motor & no need to change any Parameters.
    A06B-6079-H106- 9.1kw & rated output is 52.2Amp

    A06B-6079-H208- 9.5kw & rated output is 18.7Amp

    need to know that A06B-6079-H208- is dual axis drive

    A06B-6079-H106- is single axis drive.

    if you replace drive from -H208 to -H106 you have need more 1 more H106 drive or lock 1 axis by Parameters or dummy on axis board.
