Hi Macca,

I got your email but thought I'd reply here then others can get some thing from it if needed,

You don't need an On/Off and can just use the Mains switch on the wall but a separate switch is nice to have and simple to fit. Just use any switch rated to handle 240V and break the Live wire or better still a 2 pole switch and break both Live and neutral. Don't break the Earth wire.

On a separate note to be safe you should really have a latching safety circuit built into the E-stop that turns off power to the drives when pressed and won't be allowed to reset until all is safe. The easy way to do this is with a Relay and Momentary button wired in series with the E-stop. If you want to do this just say and I will draw you a circuit showing how.

If you don't have a latching system the moment you turn on power the drives will become active so if say for instance the E-stop was released and UCCNC was running code when turned on the machine will instantly start moving with no clue where it is and will crash.
With a latching system this can't happen also a signal will be sent to the controller saying an E-stop is in place and won't allow UCCNC to Reset.

L1 and L2 are usually the Mains Inputs but without seeing and knowing more about the VFD it's difficult to know or advise safely. Give better pictures

Again you need to explain better what your meaning is, if you mean can the power Inputs be joined together then yes that's no problem. If you're talking about the Outputs then you need to explain better what you are trying to do.?

Cheers, a latching system would be good if you could do me a diagram , as for the VFD the wires are coming from L1 and L2 and i cant remember what they were attached to, yes i want to join the power inputs so they operate from one cable. What about fans i have 2 were do i connect these.Attachment 30886 Attachment 30887 The cables from the VFD went to in1 and ov on the old board.

Cheers for all the help, I'm sure I will need more.

Attached pic. colours might not match yours but should show you how it's done.

Edit: Note that you need a contactor rated to suit the PSU which turns on the drives. Don't use a Relay if you are switching DC to the drives.

They are the Mains Input so put Live to L1 Neutral to L2.

Need to know more about the fans.

Just 12v pc fans 2 wires

still confused by were to put VFD wires coming from L1 and L2 also on off switch not got a clue how to wire this, if it wasn't for this forum and youtube i would have blown up by now.

Found vfd manual but dont understand it Attachment 30900

Decided not to go with on/off switch, turned on and lit up fine and also vfd came on , only problem is the 2 wires in pic from the stepper drivers, if i put them in + - on the psu then nothing lights up on them and also it knocks the 24v light out on the AXBB-E, So have i wired them up wrong.
Once again cheers for the help.

Attachment 30903 Attachment 30904 Attachment 30905

All sorted, all lighting up like it should, just need to setup uccn program now...That will be fun...see you all soon and many thanks

Back again , need help getting the spindle to spin in UCCNC, can move all axis but cant get spindle to move.
Any ides much appreciated

Simply connect Fwd to Gnd and it will start. If you want to start/stop it through the controller using UCCNC then use an Output which controls a relay and run a wire from Fwd through a NO contact back to Gnd on the VFD.

Nope still wont spin, also in uccnc when you set the jog why does it always revert back to 10% when you restart.

can get spindle to spin if i type m3s12000

Also what plugin do i need to get mach3 to notice the axxb-e.

Had a look at the diagram in the vfd manual.
S1, S2, FWD, REV all simply loop in parallel into the ground connection.
So if you want to use say a simple switch on the fwd, it simply goes- From FWD, into switch, out of switch, into ground. So, a straight ground sinking connection.
So for now get a simple 5v relay module on an AXBB-E output and simply use the NC/COM or NO/COM connections in the place of the simple switch I mentioned above on whichever controls you want.
Figure the AXBB-E board out later. Just going straight from an output alone won't work.

As for the 0-10v AVI. Your vfd looks to be 10v pot type operated analogue control. Have you set the jumper inside AXBB-E in correct 10v position?.

cheers for the reply Daz , not set any jumpers, were will i find it , also do you know how I get mach3 to work as it doesn't find the axbb-e controller.
cheers, sure i will be asking more questions as I'm not that savvy on things like this

Have you downloaded the mach3 plugin from cncdrive website?.

Nope...but will do now.

If i loop S1 S2 REV FWD should there be any other wires also or just the loop.

Must be blind i cant find it

Vfd Wiring diagram is on this page:
http://whzoncn.com/m/view.php?aid=83
You can see the loop and the break of the switches.
(ignore the 0-10v,, it's showed for pot use).

Mach3 plugin here:
https://www.cncdrive.com/AXBB.html
It's the ucx00 auto installer file.

The jumper is inside the AXBB-E top cover.
Easy way to test first is if you midi M3S24000 and the max the spindle spins is only around 12000rpm then it is likely jumper set as 5v (half speed).
UNLESS.... Your spindle full speed is less than 24k. If so, set full speed in midi and see if you get half or full rpms.

That is normal and kind of safety feature so you can't jog the machine too fast without first changing the speed.

Well, it's working then.? The spindle won't spin unless you give it a speed. M3 is the start command, which turns on the Output which drives the Fwd command on the VFD, and S12000 is the speed. So if you type M3 or push the Start spindle button but haven't given it a speed so and it's at Zero speed then it won't spin but the Output will be active and the FWD command given to the VFD.

It's on the CNC drives website but why would you want to use Mach3.? It's shite compared to UCCNC and it's no longer supported.!

Just to see what it was like....Have wired the vfd the way Dazp1976 suggested . but now it will only start when i turn switch on and it wont let me use any m3 commands in uccnc , so cannot change speed , not had a look at the jumper yet , will have a go in a minute
cheers

Don't need to do that it's set for 10V and ignore what Dazp is saying he's telling you wrong. I will explain in my next post don't anything else until I do as you could damage the VFD or Controller. Turn it off and wait 10 to 15 mins I will show you how to do it.

Don't do that.!

The S1 and S2 are just set speed ranges determined by parameters in the VFD and you choose one or the other not both at the same time. Rev and FWD are what they say and obviously, you don't want both on at the same time.!

However, you have an Analog 0-10V speed output on the AXBB-E which you can use so you don't need the S1 or S2.

REV is not recommended as it will unscrew the collet nut so most don't use this either. So you only need FWD which I explained how setup further down, and for setting the speed you use the 0-10V output which connects to the Analog inputs on the VFD. There may be parameters that need changing in the VFD wire it as shown in the pic and if it doesn't work let me know and I will look at the VFD parameters.

Did what you sent me, can turn spindle on/off from switch, can change speed and speedrate in uccnc, and spindle stars when i star a program, o all working for now accept my z axis, itmoves up and down when i press up and also up and down when i press down, also just need to attach probe and e-stop if you have any diagrams. cheers

I didn't mean altogether. I said they were Parallel.
Should have been clear on 'using only what you need'.
Gave the VFD wiring diagram/manual showing how it was a loop style circuit. Each one individually switched

Wasn't sure if AXBB-E was preset to 10v out. That's why I said test max speeds first to see if you get 100% or 50%.

If you're going to dabble in cnc, you NEED to be able to at least read a wiring diagram.

Your diagram in post #61 shows how the relay on the output activates the loop circuit for fwd on the vfd as I said.
Relay connections on outputs is covered in AXBB-E manual. VFD switch connections are covered in it's manual.

There has been more than enough diagrams put out.

Not sure what you're saying here.? Are you saying it moves opposite to the direction pressed as in up goes down and vice versa.? If so then simply change the Active hi/low on the Dir pin for the z-axis.

Meaning. Check/uncheck the active high/low tick in the cnc software on the axis pages, if it goes opposite directions.

Not swap the high/low wiring around on the actual pin!!!!.

changed active low and it still does the same, if i keep my finger on up the spindle goes as far as it can go the comes down, goes as far as it can go then goes back up.
And Daz yes lots of diagrams put out thanks to Jazz and I hope he puts more out to help me get this sorted, I don't mind asking for help because I don't understand it, But maybe I might learn with all the help I'm getting.....Oh one more question , what colour is the live in a plug.
Thank you and goodnight.

It's the same colour as Mud because that's where you're likely to end up if you are not taking the piss.!!

Hahaha taking the mick , sorted the Z axis it was a loose connection , so all i need to do is sort probe and e-stop out.
Also Jazz the 10v on the vfd does that need a wire going from it to anywhere.
Many Thanks.

No.
The vfd 10v is to give power to a manual 3 pin potentiometer. Then the pot dial adjusts that voltage and sends it back into the avi input via the wiper based on where you position the dial. Then it has a 3rd wire that goes to gnd .

That's how that one works.

If you did want to add a manual pot you can use the analog inputs on the axbb-e.
There are 2 on it so you could manually override both the spindle rpm and the feedrate using the wiper wire on a 3 pin dial if wanted.
I'm doing this on my 300eth.

Glad you figured the Z out.

The first project I did after rebuild thanks to all the people who gave me advice and diagrams. Machine works brill.
