step and dir pulse problem Mach3

Hi Macca,

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

Do I need to wire on off switch, if I do …how, or can I just plug in without it.

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.

Wires coming from L1 AND L2 from the back of VFD where do I locate these.

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

Is it ok to loop my 5v power supply from my 24v power supply or should I use separate supplies.

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. 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.

What about fans i have 2 were do i connect these.

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.
cheers.

Found vfd manual but dont understand it NZ100.pdf

[mrmacca]

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.

[mrmacca]

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.
