step and dir pulse problem Mach3

[dazp1976]

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.
Cheers

Must be blind i cant find it

Vfd Wiring diagram is on this page:

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.

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

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!!!!.
