I also recommend wiring the VFD and 3 phase motor together (on the bench or on the floor) and make sure you can get it running first before installing them on the lathe. Baby steps.

I tried the bench test and thought I was home free but when I did the installation on my mill the motor didn't have the "oomph" to turn the mill pulley.
I either didn't program the VFD right or the 3 phase motor isn't any good.
I guess I should take the 3 phase motor to an motor repair shop and have it tested and, if I'm lucky they might be able to program the 
Huanyang HY04D023B properly. 

Steve,
I'll bet the motor sounded funny too right? But it did TURN on it's own? That is baby step #1.
Baby step #2 is turn the frequency up and down to see if the speed changes as it should.
Baby step #3 is to put a light load on the shaft (I used a shop towel and my Kung Fu grip ©  ) to see if it has any torque. If not, you most likely don't have the motor parameters in the VFD set correctly.

This is why I advocate doing this on the bench instead of the mill/lathe. At least your mill/lathe would still be usable until you get the parameters figured out. Number of poles/factory speed, HP, amperage etc., etc. Believe you me, I had to go through my manual a hundred times before it finally clicked and I got mine running correctly. Well, almost. It ran but it ran backwards from the way I wanted it to. I racked my brain for weeks going over the manual again and again until I spotted my error. I made an ASSUMPTION and it bit me. In a long list of default relay settings that all said NO (normally open) I chose the ONE relay in the group that had a default setting of NC (normally closed). I ASSUMED they were all set to NO.  

I changed ONE parameter in the VFD and suddenly all was right with the world. Anybody that says doing this for the first time is EASY is lying through their teeth. There is a definite learning curve involved.  

Can you post the specs off of your motor plate? That would help.
