F1410HS CNC Project with Acorn

I remember now. Pretty sure we have you what you needed to try

Went through the different threads about my machine and there's nothing about built-in VDF connection to acorn...

As first step: do you think below wiring is possible (connecting COM from acorn to COM in my machine) ?

Please review the attached Generic VFD schematic for Acorn. It is in your Acorn schematic set.
Follow it for hooking up your VFD.

You already know which inputs are forward and reverse. You know the voltage. Use the dry contact relay board as your switches now.
Do that first and leave the 0-10VDC input for last.

You can test all of this on the bench without connecting to Acorn relays.
Just as I did in the GS1 Video. You should do that first before making your connections. You can use a common 1.5V to 9VDC battery as your analog voltage source. If you have a bench power supply, you can use that as well.

I kinda feel like I am building this machine for you.....

You are not too wrong, indeed... this is first serious electronic project in my life... and really appreciate all guidelines because I am really clumsy on these things
I will CNC machine some gift for you when kickoff is successful !

Test ANin and ANgnd with 1.5-9VDC battery or bench power supply.
Use a jumper wire to jump from 24VDC to FORWARD (M-CW?) input
See if motor runs in forward
Use a jumper wire from 24VDC to REVERSE 9(M-CCW?) input
See if motor runs in reverse

If so, you have most of what you need.

What I do not see is a way for Acorn to reset the VFD if there is a fault. No Drive Reset Input. Without documentation, you will have to ask the manufacturer if there is a Drive Reset Input

And also additional solid reason for decide Acorn, apart of good sense of quality, is the good setup to get support.
I intend to use CNC mill to produce prototype parts for motorbike suspension, kinda serious work, and I thik that was the rsight decision.
I also have CNC12 pro and wireless MPG.
Probably in future will install a new spindle with pneumatic tool change, but that's the future, let's take first steps first...

Hello,
I have assigned VFDResetOut to Output 6.
How that output is activated from control panel?
I understand that it is to send VFD a signal to reset it in case of EStop.
Thanks
Lorenzo

That output is cycled only when physical Estop button is cycled

"Milling in the air"... my first thread milling: https://www.youtube.com/watch?v=BBAa4gcp9W0

I have checked 0-10 VDC input of Wabeco's built-in VFD with a 1.5 battery and it works perfectly fine. I believe it can receive GND and +VDC from acorn board.

Also bench tested generic VFD schematic and feeding with +24 VDC the center terminal of OUT4 relay and connecting the output to center screw of OUT5 (VFDDirection) it works fine; can generate the 24V for either direction, so Wabeco's VFD takes that to rotate in either direction from two terminals in OUT5.

I think I am gonna start building the actual cabinet.
