Hey Shane,
Huanyang HY Series don’t even support sensorless vector control. It’s just chinese crap with Huanyang printed on it (also available without Huanyang printed on it). If you want a good VFD (which will pull out most of the performance out of a spindle), buy a Omron MX2, Hitachi WJ200 or Invertek (Made in UK).
Don’t ever buy a VFD which omits the VFD input current rating.
