Need Help! Fuji Frenic VFD Set up.

I am wondering if anyone can help with the set up of a Fuji frenic mini VFD on a Chinese HF spindle. I have the spindle running but not at full speed and it is also noisy.
The spindle specs are: 220VAC, 3.35Amps, 400hz., KW 0.75, max rev 24,000.
The VFD is 115v input. 220v output. 4 amps. 400hz. max.
If anyone is using a similar set up successfully and would share the specs. used I would be very grateful. Probably save me much time ( and perhaps a spindle!)

thanks
