got it in, here is a couple pdfs of the control

do i need reverse? is it for tapping?

Reverse is both for tapping and running in low speed. Yes, you need reverse.

Looking at the Forward and Reverse relays on the upper right:
Disconnect the black wires connected to terminal 9 on both relays
Disconnect the wires from terminal 8 on both relays

Connect the VFD COM to terminal 9 on both relays
Connect the VFD X1 to terminal 8 on the Forward relay
Connect the VFD X2 to terminal 8 on the Reverse relay

Disconnect the wires from right hand side the 30 amp fuses, leave the fuses connected to the main switch.
Connect F1 to R terminal on the VFD
Connect F2 to S terminal on the VFD
Connect the VFD ground to the panel ground, and make sure the motor is grounded through the motor cord. Should be a 4 wire cord.

This should be all you need to do to interface with the existing system.
 
Well it was over 92 felt like 100 so waited til this morn..
One of the fuses is the white line and the vfd said it didn't need it... Just has ground in... Figure would just hook up white but would ask before power...
 
White line? If you're talking about a neutral, there is no neutral used in a 3 phase system (original wiring) The wire just happens to be white in that cable. When converting from 3 phase to single phase, I normally disconnect the white wire and cap it off on the free end of the cable, and cut it back and tape it on the power plug end.

It can be a bit confusing with a white wire in the cable and you are used to working only with single phase circuits. You will only be using the red and black wires.
 
so the white neutral line coming into the fuse just ignore
and hook a ground from the case post to the vfd
or pull off post and put it through the fuse?

black/red = hot usually L1/L2
white= neutral
green=ground
 
You are a bit confused, the white wire is not a neutral it's one leg of the original 3 phase. The wire just happens to be white.

In the original configuration:
Black = Hot (L1)
Red = Hot (L2)
White = Hot (L3)
Green = Ground.

So you are only going to use Red and Black (L1, L2) and Green Ground.
The Ground will be connected to the panel ground and to the VFD ground. A ground is never fused.
White will be capped off and not used.
 
Welp got it wired up but wanted to check something... There is a resistor between B, what you called 8, and the A. where the yellow, orange and brown wired are.

Leave em and see what happens or Pull em see what happens when fired up.
 
That is a diode, leave it in place.

But I did make an error, I did misread the label on the drawing, rather than terminal 8 (top left), it should be terminal 5, on the top right of the relay.

The original wiring on the A and B terminals should not be disturbed.
