Re: cant figure out how to hookup, yes I read all docs
Ok stuck on a couple wires coming from my VFD that are labelled different than what the acorn schematic has.. im sure its just from being new and not centroid fault..
VFD - "10V" connects to MACh3 Controller as 10V in (in the second spindle category)
VFD - "AVI" connects to mach3 controller as AVI
VFD - "ACM" connects to MACH3 controller as ACM
When looking up the VFD's manual... https://salecnc.com/manuals/Inverter/BE ... nglish.pdf...
it has vague answers as to what they might be. The manual reads..
AVI - Terminal Name "Frequency voltage input setting" Explanation: Input 0-10V, PID Given or feedback
ACI - Terminal Name "Frequency voltage input setting" Explanation: Input 4-20mA, PID given or feedback
10V - Terminal Name "Frequency auxiliary power setting" Explanation: And AVI, COMD Connected potentiometer (4.7k-10k)
Other than those wires in question I've already hooked up the DCM (common ground) to relay 4,5,6 and the Spindle Forward to the correct relay (OUT4). It seems this VFD didnt have wires hooked up to RESET, or REVERSE.
The rest of the wires I have not wired for the spindle that are in the Acorn Installation Manual are:
0-10V VDC (which im assuming is AVI.)
0-10V VDC COM (which im assuming is ACI)
FAULT COM (not sure?)
FAULT NC (not sure?)

Re: cant figure out how to hookup, yes I read all docs
Do not hook up 10vdc FROM the VFD.
Acorn provides the 0-10vdc analog signal.
AVI is probably what you want and it's Common.
Read the VFD manual
Fault Com gets Connected to Acorn Common.
Fault NC gets Connected to an Acorn input and assigned Spindle OK.

Re: cant figure out how to hookup, yes I read all docs
Sorry I realize my last part of that post might've been poorly written. I don't have any other wires from the VFD except the AVI, ACI and 10V. The 10V I will just unhook from the VFD and forget about. I will hook the AVI and ACI into the proper places into the controller main board.
I dont have anything from my VFD that I can wire into the Fault Com or Fault NC. so do I just forget about these and keep on trucking to the next steps of the install?

Re: cant figure out how to hookup, yes I read all docs
First, I am a little skeptical of the inexpensive Chinese drive you have. I hope it does not cause you headaches in EMI noise and programming..
Second, the manual you linked to shows it has relay contact outputs. YOU have to program them using the parameters as to how they function.
I skimmed through the manual Relay output Y1 is controlled by parameter 101. You would program it to value 4 Fault. That is, if the VFD faults the relay will activate, in turn when wired to SpindleOk input on Acorn, will allow CNC12 to see there is a problem and fault stopping the control.
Take a little time to read through the VFD manual and familiarize yourself with it and how to program it.
I strongly encourage you to program and use this VFD output. You can imagine what could happen if the cutter is engaged with the work piece and stops cutting. Use the Centroid Generic VFD Schematic for guidance. Schematics and other Acorn documentation can be found here: https://centroidcncforum.com/viewtopic.php?f=60&t=3397

Re: cant figure out how to hookup, yes I read all docs
Ok so I went into the VFD's programming menu and P101 is assigned to 4. So that seems to be good. What I am not understanding is what I need to wire up. Going by what you mentioned I need to connect Y1 to the spindleOK input on acorn board in the spot H1 - IN5. Ok I get that. The schematic says that comes from the FAULT NC from the VFD. So I assume that will be the Y1.
I see the VFD has a COM port on there as well. So would that be the FAULT COM that would connect to H9 section on the acorn board?
Only thing left in the VFD section would be Spindle Reverse, but thats not an existing thing so either my spindle is not set up to go in reverse, or its another menu i have to program for the VFD. Either way, I dont ever run the spindle in reverse so it might not be that big of a deal. Again, maybe my inexperience is speaking on that matter.
After this I can finally move onto the touch probe thankfully. This has taken one week, for which I had planned on but definitely was hoping to be doneby now haha

Re: cant figure out how to hookup, yes I read all docs
Please take a picture of the VFD showing its terminals and upload it here
The Chinese manual is terrible, shows NO diagram of the VFD and its connections
From page 11 of your manual: Great manual. (SARCASM)
With the VFD powered OFF,
Run a continuity test from Y1A to Y1B and Y1A to Y1C.
I think you should read continuity between Y1A and Y1C
IF you do THEN:
Connect Acorn Power Supply COM to Y1A and connect a free input to Y1C and assign the input chosen to SpindleOk
If a router, don't bother with reverse

Re: cant figure out how to hookup, yes I read all docs
Yes the manual is trash. Lol. It says I have a "X8" port but I don't..
I tried to get most of the labelling in the photo. Behind the ACM it is marked 'COM' thats the only port i couldnt get a clear photo of

Re: cant figure out how to hookup, yes I read all docs
So I disconnected the power to the control cabinet and shut off the breaker. MY old multimeter was not working to test continuity (edited)

Re: cant figure out how to hookup, yes I read all docs
Common terminal for relay 1 is Y1B. You should have continuity between Y1B and Y1C when the power is off and Y1B and Y1A when the relay is energized. Relay #2 is normally open between Y2A and Y2B. There is no Y3 in either the terminal listing in the manual or the photo above.
Cheers,
Tom
Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Re: cant figure out how to hookup, yes I read all docs
Apologies I mean I tested Y1A and Y1B and it didnt show continuity, do I need power connected to the CNC control box just powered off? Because I removed the plug from the power receptacle.. I just like to be safe when working around electricity loltblough wrote: ↑Fri Dec 10, 2021 7:15 pm Common terminal for relay 1 is Y1B.
