Just recieved a Huanyan HY02d211b inverter and a 2.2 kw spindle 110 volts. Having issue with the spindle rpm is at 11,500 rpm ,supposed to run at 24,000 rpm. Not sure what is wrong or if code are set wrong. Just setting this up to run on its own,not running this in mach3 for now. Just trying to get it to run. Any help is appreciated. Do not know much on setting this up .
  Thanks Dan

You need to set max speed and freqency (400Hz max usually) in the VFD and also if its a router spindle ramp up and down time too. 

I changed some of these settings. And now the spindle works just fine. Thanks for the help.
        Thanks Again! Dan
