Looks good.
I have one of Bobs boxes as well! I was thinking about adding a shed of fibro to stiffen things up a little.
What are PD072-75 set to?(I ask I think my manual has them mixed up)
Try
Higher Analog Freq = 90(PD072 in my manual, but I think it should be PD073)
Lower Analog freq = 30(PD073 in my manual, but I think it should be PD072)
Been a long time since I used them
Good luck
Stuart

I have fitted a multiturn pot so you don't notice what isn't being used. It also allows you to work out settings for different speeds. You can put up a chart and just crank the dial to the right number.
This link shows the type I use, but it is not the right resistance range.

I used a sheet of 6mm? ally to stiffen up the back and it also helps draw heat away from the heatsink at the rear of the VFD.
30Hz is a bit on the high side for a minimum.
I'm not using it often or continuously but I go as low as 10Hz on my lathe - (mind you that is a vector drive) but you could go down to 20.
I find a really low speed like 5Hz useful to see what is going before I crank it.
