Really quick and dirty video of how to connect the Mach3 USB controller to a VFD for spindle speed control. Let me know if you have any questions.
Hello, good Video.
For my inverter I need a real analogue signal. To set up the RC I need to know the frequencie of the pwm signal. Does anybody know that frequencie?
Good content. I sent my Precix controller to Patrick for an upgrade. He did an awesome job, I was very pleased. Thanks Again!!
You are very welcome!!
You're the man!!! I was stuck and could not control my spindle with mach 3 until I saw your video. Thanks a lot
You're welcome. I'm happy the video helped.
Thanks a lot for your Videos, I learned so much.
Great video. I have connected my vfd and set the configurations according this video. Everything works perfect, but I still have one question. In the Spindle setup I entered 200 in the field for the PWMBase Freq. Now I measure a PWM signal at the AVI terminal of the BOB with a frequency of 1000Hz. Should this not be 200Hz? What could be the reason? What do I have to change to obtain 200Hz?
do you have the link to your video were you connect the Output of the card to the vfd, does it go to the FWD?
Can i connect the spindle vfd to 10v and add a laser to 0-5v as pwm and add a dpdt switch to switch between spindle and laser? Sorry for my bad english. 😂
Hello, I have a problem with spindle speed because it varies constantly. I did all the same settings but not working. Do you have some advice? I tried setting speed with potentiometer and its stable speed, but with board its not, all wiring is the same
Hi, i am new at these things, i have an cheap chinese board with the same vdf.
The ports on my board are (v+ and gnd to give the board 12v-24v power) and the other ports are (fwd avi pwm and 10v) i am not sure where to connect those ports to the vdf. Any advice wil help, thanks.
Important , what is your Spindle motor tuning numbers. in MACH3
Thanks for sharing, I have the rnr controller you are showing, do I need to use a relay in order to run my spindle? I have a Hy 2.2 kw spindle. Thanks in advance
Yes, I would use a relay. In the VFD manual, you will notice that the FOR, or REV will run if connected to gnd. You can see where I use a relay with this board here: th-cam.com/video/Qi4M3DAtTXg/w-d-xo.html
Great vid, thanks a lot for sharing! Quick question: I have the same Mach3 breakoutboard that you have here, do I need a VFD to digitally control my AMB (Kress) spindle? Or can I use some simple relay wizardry?
From my understanding, the Kress plugs directly into the wall. If you wish to control the on and off of the Kress, you can use a simple relay. There is a speed controller on the Kress, but you would need to research someone that has already done a teardown and applied some kind of functionality to make the variable speed work.
@@PatrickHoodDaniel Thanks!
Hey. I got this board but don’t understand for example AVR, the 10v return. What pin on parallel port is that. When I look at mach3 pin out there is no AVR.
There is AVI and ACM. I am not familiar with an AVR terminal on this controller.
WHAT PARAMETERS ARE USED TO OPERATE IT DES MACH3 IN THE YL620 MACH3 AND RNRMOTIONG RED AND WIRING
There should be a parameter that sets the frequency control to the external terminals. Use that one.
Great video but I’m still lost!
I’m running g540 with a Hy 2.2 spindle,and vfd.
Mach3
All the wiring is correct and ports and pins settings are correct as far as I know.
Spindle comes on correct through relay controlled by g540 but goes straight to wide open 24,000 and can’t be adjusted no matter what.
Tried entering S command and still nothing! Ugh!
Reset vfd numerous times and still no change.
Thanks if you can help!
buen dia, tal vez me puedas ayudar. Mecesio conectar un modulo laser a mi cnc, la cual tiene una interface como la del video. El modulo Laser necesita de señal 24v, (positivo y negativo) y la señal PWM para controlar la potencia. conecto AVI a PWM del modulo pero no logro en las configuraciones del mach3 que esta señal salda de la interface. desde ya no tengo conectado inguna otra entrada como los 10v u otra como las que mostras en el video.
Gracias
¿Qué nivel de voltaje PWM necesita para el módulo láser?
Is there a parameter on the VFD that needs to be changed in order to start and stop the spindle? I understand that the source of operating frequency needs to be changed to 1, but I'm curious if there is a separate parameter for the start/stop function. I am using the same USB board and the same vfd/spindle combo, wired the exact same way you have it in this video and the outputs video. Im assuming thats pd001
Yes, there is a parameter that allows you to use the external terminals instead of the control pane. The parameter number depends on the specific VFD, but I believe the HY VFD is PD001. The terminals you will need to use are FOR and DCM to run the spindle in the forward direction,
@BuildYourCNC it was yes! I had to fiddle with the ports and pins tabs after setting the vfd though because the dual relay I had ordered had a faulty side and of course that's the one I originally wired to.
When you say inductor across the cable, which cable, the spindle cable?
The signal cable with the PWM.
Hi thanks for your great info just have a question I'm running a 2.2kw 3 phase 2 pole motor I follow yours set up and it works great but it does not hold its rpm it seems to pulse up and down. Just checking to see if you have any ideas. Thanks David
You might need to add some inductance to the signal cable from the controller to the VFD. You can use a ferrite toroid and wrap the signal several times through this toroid. Also, make sure you are using shielded cable. The number of wraps should be around 5, but refer to the datasheet of the ferrite toroid to determine a better value.
Hi there, My spindle is doing the same thing. I'm just checking to see if this works or if you found a way to fix the rpm problem. There's not a lot on the net about it. Thanks David
Hey can you put a link for the video ( to start and stop the spindle using output pins)
Thanks
Sure, here you go: th-cam.com/video/Qi4M3DAtTXg/w-d-xo.html
@@PatrickHoodDaniel thanks 👍
Hi PAtrick, I have this same Mach 3 board, I have my board connected and I can turn it on and off. I have the PWM set at 60% so when I type in 16000 rpms it climbs to that mark but constantly drops and raises the RPMS by 1500 to 2000 rpms. How can I stabilize the spindle RPMS? Thank you

I cant seem to get spindle speed control from mach3. I am able to start and stop the spindle, and the speed DOES seem to be set by the mach3 software but i am unable to change the spindle speed from what seems like top speed. I have have done everything (wiring, programming, and vfd parameters) the same way you have it set up in this video with the same spindle, BOB and vfd that you have in this video.
For anyone who is in a similar situation, in this video it isn't mentioned but there is a jumper to the right of the terminals on the vfd that is set to VR by default. It needs to be moved to the VI pins instead. This will switch the '1' option under pd002 to actually being externally controlled, instead of that option being the built in potentiometer knob. In addition, pd070 needs to be set to '0' as that is the selection for 0-10v pwm.
I bought a UT4060 cnc router and found out that the VFD and the controller board are not wired at all. I have a Rnr motion controller just like the ones you sell. Can I send you pics of the VFD and help me to wire it ? thanks.
We can help, but since the board wasn't purchsed through me, you will need to purchase a tech support token. www.buildyourcnc.com/item/sub-assemblies-Technical-support-token
@@PatrickHoodDaniel Can't you just tell me the connection for a H100 S1.5 VFD ? Can't which input is the ACM
Thanks for your video and help. I’m having a little issue, cannot manage to control the spindle with mach3. I’m using a leafboy77 board, and the same VFD that you. It works when I control from
VFD but when I try to do it remotely I cannot. The display blinks. Any clue? Perhaps is Pd002 or Pd001?
On/off control or speed control?
@@PatrickHoodDaniel Hi! I manage to turn it on, but now I cannot control speed, to make it slower of faster. It spins all time the same speed. Thanks for your help
@@CristianSanchezz22 You velocity and acceleration parameters are in the motor tuning screen.
there is the speed difference between mach3 and actual spindle for example if mach3 is givenn S3000, the spindle spins at 5000 and above rpm. how can i compensate ?
Spindle Pulley Settings. Here, you can adjust the max speed setting to bring Mach3's perception of spindle speed in line with reality.
yes i have tried but there is a non linearity in my setup speed difference is different at different rpms @@PatrickHoodDaniel
How control yl620-a with a remote control from dsp 0501
Look for wireless pendant, or wireless MPG.
@@PatrickHoodDaniel can rznc 0501 save break point
Hi, All the setting work fine for me, but I can’t reach maximum speed with the board. The max voltage turn around only 0-8.4v. My maximum speed only 21000 (My spindle have 24000). My VFD work fine with a pot on it or a 10K pot external. I can speed up max if I hack setting PD072 to 1 for simulate a 0-5V. Otherwise, I have two board and same problem. Someone can fix this?
Hi, Did you ever solve this? I have the same issue.
@@littlebigadventuring Hi. just set to PD070 to 1 for work very fine with 0-5V with thix board. I use also use analog converter for output signal.
Great
Please sir send me mach3 software full version, I have already downloaded trail version,,,my email id is below...
I’m having a issue with the output voltage. No matter the setting changed I’m getting a out voltage that varies. Unless set to max
So if set to s12000 I’ll get like 5-5.6v. But if set to s24000 I get the 10v
What setting am I missing why is my voltage wondering.
Make sure the VI jumper on the VFD is set correctly. Did you do this yet? If you don't have a jumper, what model of VFD do you have?
@@PatrickHoodDaniel basic hy 1.5kw vfd.
I believe my wiring is correct. Acm to acm avi to vi
Is there somewhere I can send you a video or picture of my issue?
@@shawnr699 Did you set the jumper. You did not mention that in your comment. That will most likely be the issue. The jumper is on the circuit board of the VFD and it is well described in the VFD manual.
@@PatrickHoodDaniel the board is controlling the spindle,
that’s not the problem.
it’s the variance in rpm/voltage.
I can control the spindle. if I set it to s24,000 it goes to 24,000. If I set it to s12,000 it goes to 12,000 and then up to 15,000 and then back down to 12,000. Back-and-forth.
Fluctuating voltage/rpm
@@shawnr699 There is also settings in the parameters to set the frequency in steps. Take a look at those parameters just to see if there is any correlation. It may be better for you to connect via RS485. You may be chasing down EMI issues on your signal wiring between the controller and the VFD.
Why did you not show the output?
That's in another video: th-cam.com/video/Qi4M3DAtTXg/w-d-xo.html
@@PatrickHoodDaniel can you show it working together, vfd controlled by the output
@@Anonymousg64 I will put that on my list. Thanks.
Dont mind the dogs barking in the background one bit it just makes you feel at home working apology not needed Matey
Thanks!!
How to reverse move motor?
If you want to reverse the spindle rotation direction, you can select the reverse mode on the control panel. If the spindle is turning in the wrong direction in the forward mode, then you can swap the U and the V connections in the VFD.
NEVER NEVER use a PWM for speed control your Spindle. VFD work only with analog input. You must use an PWM to analog converter between your board and VFD. You can burn your Spindle a weird sound like a high frequency and spindle run too hot, you can domage spindle. The VFD didn't work with a pulse.
You will not get answers here. This video RIP
@@kenf2662 what question do you have and I will try to answer it.

It's a pity that you find it so necessary to sway that camera back and forth.
If it weren't I would watch it with great interest, not now.
It gives me a headache
This was an off-the-cuff video to help a customer call today. It actually wasn’t meant to be uploaded, but I decided to anyway. I know it is abysmal quality. The swaying is from trying to hold the phone while describing the instructions. I will redo this later, but I hope this information helps folks now.
poor you first world problems!!!!!!!
