Be Careful if you don't know what you are doing because you can easily damage the controller if you connect up wrong. Don't turn it on until you are 100% sure it's correct, you can't afford to use a trial and error method here because you won't get a second chance once you let out the magic smoke.
I will knock you up some simple diagrams but it will be tomorrow now, I suggest you wait rather than have a go without being sure.-use common sense, if you lack it, there is no software to help that.

Looking at the first two images, I'm concerned about the polarity of the supply to the stepper driver. It appears to show a black wire to +ve and red to -ve, although the 24V supply to the AXBB is correct. I can't see where these wires go on the power supply.

I had replied to OP before I read your post, Jazz. Sorry about confusion.
Indeed, it depends on PSU connections at the other end of the wires but it's a disaster looking for somewhere to happen!

im nearly there I think with wiring my Axbb-e , just got a few more questions.
Do I need to wire on off switch, if I do …how, or can I just plug in without it.
Wires coming from L1 AND L2 from back of VFD were do I locate these.
Is it ok to loop my 5v power supply from my 24v power supply or should I use separate supplies.
Cheers for all the advice and help..

I assume you mean loop the mains input to the supplies. That is no problem, just do it carefully. I would advise using the correct size crimped spade terminals rather than trying to twist several mains wires together.
You can have a mains on/off if you wish. I use a 4 way dis-board with individual switched outlets with separate feeds for the AXBB-E 5V/12V supply and the 36V motor supplies.An optimist says the glass is half full, a pessimist says the glass is half empty, an engineer says you're using the wrong sized glass.
