step and dir pulse problem Mach3

[JAZZCNC]

Hi All,
been having a go at building onto the AXXB-E attached are some pics and would like advice as to were I have gone wrong on the stepper drives, also the 3 wires lying by the AXXB-E are from the VFD av1 grnd and +10v were do i attach these to the AXBB-E, also emergency stop and pump.
All the advice i have had up to now is much appreciated.

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.

Ok, here you go. I have broken each down into separate drawings.

On the VFD you don't need the 10V with AXBB so just remove the wire.



Edit: My drawings show Step which is Puls on your drives.

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.

Doesn't look like that on the images I'm looking at.? Maybe need to zoom in.?

Edit: Sorry just spotted you mean the OP pics, not the ones I posted last night. Yes looks wrong but depends on what it's like at the PSU.? Logic says its wrong

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!

Cheers Jazz,
no would not have turned it on and still wont till im sure , thats why i asked for help lol.
Actually had another read of the manual and spotted where I have gone wrong.
Cheers M8

Same as in psu lol cant afford this to smoke.

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.

Cheers for that. any idea where the red and brown wires from the VFD L1 AND L2 go onto the Axbb-e
