    Surely they do something to those motors? Running an off the shelf motor at 10k+ rpm seems a bit scary. Plus it's going to produce more than 10hp at more rpm.

    They use a delta/wye switch to give the spindle a broad torque curve. It seems to work really well.
    But, how they label these 30/40hp machines I have no idea? It is way over my head.
    All I know is I saw the motor-plate on the motor connected to a direct-drive spindle in one of these "30/40hp" machines. And, it was rated 10hp.
    That is a 10hp spindle in my book. Pretty sure there ain't no amount of magic pixie wranglin' (spindle drive) gonna increase a motors rating 300%.

    The pre NextGen controls had a spindle accel/decel parameter which would fix that for you.
    Call the HFO ( or perhaps Haas direct ) and ask if that parameter still exist on the NextGen garbage.
    You won't have access to it, but your HFO will.

    My SL10 came in ( one of the very first ones Haas ever made ) with an insanely high acceleration parameter.
    Cut it down to almost 1/3rd and it became much much nicer.
    I did not have a problem with power failures, but did have issues with spindle overload alarms when G96 was invoked.

    Tried that before anything else. No dice, said it didn't exist in parameters anymore.

    I'm willing to bet that it still exist.
    The current group of schmucks that do coding for Haas might be useless, but they can't really get away with hardcoding servo parameters into the OS.

    See if you can find someone willing to give you access to these:

    I too would suggest nicely asking in persistence, I'm not convinced there isn't a settable parameter for this.

    Yeah but tell us what size Rotary your useing and how many amps is your supply and breaker....Thanks

    And I recall someone on here was even running a modern vfss on rpc on a 30amp breaker with no issues.

    Not sure what a static phase converter is capable of, but have heard good things about that brand.
    Depends how much your demanding from the machine. The newer VF3 is 30HP direct drive and thats what I'm trying to figure out now. The rotarty Phase Converyter company is telling me I need a 50HP RPC at $5k$.......Yikes

    How many horsepower on that spindle motor?

But, you can bet haas didn't up the spec by 300%
    And, the haas motors were no more powerfull than either the Yaskawa or Baldor.

    haas ss machines will run just fine on 30 amps. I have 4 of them (three VF2ss, one VF3ss/APC) all on 30amp slow blow fuses and a 60hp Phase-Perfect.
    They run just fine!
    The neer Haas are 30 HP direct drive. Tholder ones wer less.
