Jase....i am glad you got that sorted. Yes you should be able to change the display to indicate hertz....
To control the speed you need to have a ( PWM signal ) output a 0-10v from your Breakout Board to the VFD
The right side of the display shows the unit of the selected parameter. This can be either Hz, A, V, kW, HP, %, s or RPM
You can change this to what ever you want it to be
Because you have a quality VFD Drive you can use the minimum that your spindle can run at=100
3-02=100
3-03=400
4-12=100
4-14-400

This is my power terminals. I believe the two green lined are the 0-10v on the bob. Which ones on the power supply should I connect them to?

Can anyone put me out of my misery?
Tried all morning and can't solve it....
On the old Chinese inverter I could set the speed with the pot then run the gcode and it would cut at that speed. Every time I do the same thing it runs at the spindles maximum.
I'm pressing the Hand and rotating the pot to the required speed. Then press auto on. Then run the gcode but it spins up to 24k.
Any ideas?

I would be able to help you, sorry i didn't reply before....been flat out, we just moved and busy renovating. Not sure when i will be able to though, i already got a vsd and same bob as yours ready to set up so i can give you the connections and parameters. Hopefully i will get some spare time next couple of days
Tried wiring the Bob to the inverter today but as I never built the cnc machine I'm lost when it comes to the configuration in mach3. I can get it to turn the spindle on and off but if I run gcode it runs at 24k rpm and can't alter it. How do I workout the pins etc for the spindle motor?

Here is a setup that was done for a lathe, this will show you what settings you need to do in Mach3 yours will use different numbers to this and you won't have the spindle feed back
There are a lot of you tube videos also, and information on the Mach forum Machsupport Forum - Index

Mac been trying to get this drive to allow spindle speed to function from both an external box pot and from mach3 without success. I keep reading the manual to see if like my old drive there is a setting where you tell it to take commands from an external source but cannot locate it. Can you help?

I think my issue may be with my Bob. I wired it like this. The left hand side Estop is p10 and gnd but when the connection is made nothing happens. I wired the right hand side as you advised but nothing functions. I found this manual and copied the pins (my setup didn't come with one) so pwm is on p1. However nothing happens. The relay on off to the spindle does work but runs at max.
Am I doing something wrong here or could the Bob be faulty?
Thanks.
