Check the ohm reading of the spindle pins
Pin 1 to Pin 2=
Pin 2 to Pin 3=
Pin 3 to Pin 1=
Pin 4 to Spindle body this can be a continuity check
It points to the spindle motor, that has a problem, it should of been able to run on the supply you have now
Can you get a replacement spindle motor, if you do go for a 1.5Kw seeing you only have a 120v supply.

Received a 1.5Kw spindle in the mail today from Amazon for testing. Plugged it and it sang right away. Absolutely no issues. I'm primarily a woodworker but went with the 2.2Kw because bigger is already better right? I think this is going to be perfectly fine for my needs. Thank you so much for your help getting this running Mactec54. Luckily I can still return the other spindle. Just for my future knowledge are there any preferred or generally better regarded VFDS out there? I still fall squarely in the DIY crowd and the huanyang is well regarded there, but I don't mind paying a little more for quality.
The problem is you are running 120v so there are not many VFD Drives that would be better than what you have, 1.5Kw is normally the limit for 120v single Phase supply, the other spindle should of run though, but not that great, so I think it was damaged
So, you should change the Parameters back to the original set I posted except for your motor spec's need to be changed Amps 7 for the 1.5Kw
Bigger is not always better, if you don't have the juice to drive it, 240v the 2.2Kw works best

Thanks again Mactec45 you're truly a massive asset to this forum and to the net.
One more good house keeping question. I'm using ring terminals on my grounds, but this vfd only has a single ground terminal. Is there a preferred method to connecting more than one to the same ground besides stacking ring terminals?
You should have a Ground Bus, mounted in your cabinet, Metal to Metal no paint under it, this is where all the Ground wires are to be connected, at the same point, the snips are the ideal, you can also use a stud and stack each Ground connection, with star lock washers and nuts for each connection, this is messy and not as good, compared to a Bus type bar, which you can make it yourself
So, each item that has a Ground wire connection, all should have there own Ground wire connected to the Bus
Shields connect direct to the Ground Plane, P-Clamp type is the best, or EMI Glands for shields, saddles type clamps work but not as affective
