Wiring a 3 phase motor for VFD is generally very straightforward.
Check the data plate on the motor says 240V in Delta
Set the motor into delta configuration
Wire the 3 outputs on the VFD to the 3 motor terminals
Wire a plug into the VFD
Add a run switch, and speed pot if you like.
It's fiddling with the parameters that takes a bit of doing but you really only need a few of them to be correct for basic functions. The better units have auto-tune which will configure the motor parameters for you but even if you don't do that it will be easy to get it running at least somewhat.
I bought a VFD last week for my cylindrical grinder and wanted to test it. Took just 15 minutes from getting it out of the box to getting the motor running and half of those was reading the manual to switch it to control pad functions.
If you're a little bit daunted buy a Chinese unit like a AT2. Pretty hard to get them wrong.
