Sorry, I guess I missed the post about the 3ph motor.
What I would do is 'start simple'. You have the motor mounted. You have the VFD mounted. The confusion seems to be over the wiring.
Why not "just get it to work" first and then move on to "and now I want to make the controls user friendly". By this I mean wire up just the VFD and the motor and make sure that it works. I've actually run my drill press that way for several years with the brake resistors and easy-to-use remote pots and switches sitting patiently near by in a cardboard box. The need for holes out weights my need for convenience so I just never seem to get around to finishing up the details. But I digress.
If we assume this is the canonical reference document ... https://cdn.automationdirect.com/static/...2m/ch2.pdf ... you can go to page 2-8 to see everything you should need. The 'output power connections' picture show how to attach the VFD to the 3-ph motor. The "1-phase Input Power Connections" shows how to attach the VFD to power line.
You will then be able to turn on the VFD, program it [as Willie suggests, a non-trivial task], make the motor spin, control the speed via the knob on the front of the VFD, even use the G0602. You will be ignoring any of the exiting controls and using the VFD exclusively. At that point you have a working system and can noodle over what is required to make the remote switches and pots work the way you want. But you do have a working system to start with and to build upon. [chanting 'don't change everything all at once']
Having offered this advice, I will reiterate what Ed and other have suggested. You are working with power line voltages on the input to the VFD and greater than power line voltages ... as much as 400 volts ... on the lines to the 3-phase motor. THESE WILL KILL YOU WITHOUT HESITATION OR REMORSE. If you are 110% confident that you know what you are doing [proper grounding, wiring, proper grounding, wire routing, proper grounding, insulation, proper grounding, wire size, pro...] then please think about it a little more.
