I have been doing a lot of experiments on my Huanuang (Genuine) VFD. I now have three of these.
1. 2.2 KW unit 220v input
2. 2.2 KW unit 110v input
3. 1.5Kw unit 110v input

The machines function identically, you just change parameters based on what motor or spindle you are controlling.
Note that with the genuine Huanyang VFD you can control both 110 and 220 volt motors.

So all that said, the write up has been updated.
