Poor John, you must be on overload with information by now - too much!!
I get the feeling you are on the right track and will probably be all right. At the risk of causing more confusion. I'll offer this picture of my Hitachi hook-up - it should be like yours - and point out where the wires go..
Along the bottom -- on the left are the 3 incoming 220v 1ph wires (L1 L2 & N) I put a 220v 20amp simple on/off toggle in this wire to turn power to the VD on and off. Next to them on the right are the 3 - now changed to 3ph wires (T1-2-3) going to the motor. If you only hook these wires up, the VFD will run the motor with the controls on the unit, but it will only run in one direction using the on/off buttons (which you can change by crossing any 2 of the L1-2-3 wires) To benefit of the many functions of the VFD, they have to be programmed into the unit and controlled with the top row of connections...
At the top, the 3 small wires (PCS - 1 & 2) are going to (in my case) an on-off-on switch that is reverse in down, off in center and fwd in up. I use the pot on the VFD panel to control my speed.
Hopefully a picture will help --- and my attempt at pulling from memory and explaining the connections are reasonably accurate....
