    Default Hy 400hz vfd + 2.2kw spindle +300eth-ub1

    i set up vfd as per mactec54 parameters for hy. What happenned, is that at max speed in controller (24000) i only get 380 hz (22800) on the vfd.

    Documentation of ub1 board says it can only send 9.8v to the 10v signal of vfd. So that might be the issue. Is there a parameter we can trick in uccnc or in the vfd so i Get the 24000 rpm.

    not that it is a real problem to have only 22800rpm, but annoying as a builder

    Yes, there is a workaround that I used.

    I set the VFD to 0-5V, instead of 0-10V, and I think I set the Max PWM % in UCCNC to 50%. THis gave me a 0-5V signal from the UB1.

    You could also use a 12V supply to the UB1 to get a full 10V from it.
