Identify the Control Signals: First, determine which control signals from the DB25 interface card are used for spindle speed control. Typically, these are PWM (Pulse Width Modulation) signals or analog voltage signals.

VFD Configuration: Your VFD should be configured to accept the type of control signal your DB25 card provides. This involves setting parameters in the VFD that correspond to the type of input signal it will receive for speed control.

Wiring: Connect the appropriate output pins from the DB25 card to the input terminals on the VFD. This usually involves connecting the PWM or analog output to the corresponding input on the VFD. Make sure to consult the manuals for both your VFD and interface card for specific wiring details.

UCCNC Settings: Configure UCCNC to output the correct type of signal (PWM or analog) that matches your VFD's configuration. This is done through the software's spindle setup section.

Test and Adjust: Run some tests to ensure that the spindle speed is being correctly controlled by UCCNC. You might need to tweak settings in either the VFD or UCCNC for optimal performance.

Hey ! I have purchased a VFD with matching spindle 1.5kW and control program UCCNC. And my interface card is DB25, the question is how do I connect the VFD to DB25 so that I can control the speed with UCCNC? Sincerely "cnc beginners"

Depending if the spindle can work with this specific VFD, it might be possible. However we would not like to risk you working unit, with a possible match so we would like more details on your specific model and any information available on the spindle itself.

Response
The only info on the spindle is 2.2KW 400HZ 220V. Made by Zhong Hua Jiang.

Was originally on a Delta C200 vfd. That is 220 single phase.

Do you have an oscilloscope? You will be able to see the PWM signal and determine if the output is correct. Make sure that you are using the 10V from the VFD as the voltage reference for the 10V terminal on the Mach3 USB controller. The 10V terminal is an input, not an output on the Mach3 USB controller. The 10V is the top voltage signal level that the Mach3 USB controller uses for the PWM signals 100% duty cycle.

[575] I have the wiring and programming and parameters set the same way that you do in the spindle speed control and outputs videos, I can start and stop the spindle with mach3 but can't seem to control the speed. Can you think of solutions?

When dealing with 3rd party machines, we have a universal setup that will fit almost any other machine, although please take in consideration the specifications in which your stepper motors and drivers are used and set to!
Now changing the controls, would be more or less changing the Breakout board/interface board to a different one that might use a different program to run your machine. Usually you will not need to change your interface board or breakout board, unless the 3rd party manufacture made it specifically to that set up.

I am looking at purchasing your 2.2 kw water cooled spindle. I'm assuming it comes with the VFD. I have a rotary phase converter in my shop. Are these spindles 3 phase? And if so, can I bypass use of the VFD and control the spindle speed by the CAM software instead? Or is the VFD an absolute necessity to use on the spindle?

Our spindle VFD's, have a multitude of different connectors that can be used for different operations. There is a manual that comes with each VFD, and you can refer to page 11 for different functions and descriptions.

We currently have a PWM, working with our machine, however it is connected via USB, and setup through Mach 3.

It is possible to control externally the 1.5kW Inverter (VFD) (220 Volt) with PWM so i can control the spindle rotation? Do you have the documentation? Thank you

A wireless MPG is generally independent of the controller since it communicates to Mach3 directly and does not pass through the controller. I am using a wireless MPG and I have no problems with either of the controllers that I sell (Mach3 USB controller or the Pokeys57CNC controller).

The issue you are having may be in the configuration of the wireless MPG that you are using.

Click the link to add information to this solution:
I am trying to decide which board I should use. I have a wireless MPG and every time I jog Z my X axis steps. If this is not a board issue I would like to go with a wired MPG. So I would like a board that I can have a wired MPG, use a tool touch off probe, control either spindle (VFD) on/off or on/off with speed control, and have homing switches.

That will depend on the controller that was installed in the redFly. If the controller is a pokeys57CNC controller, you can use Mach 4 with that system.

You can add a 4th axis and an ATC (Automatic Tool Changer) with the redFly system.

Does the Redfly that I bought with the GreenBull in 2016 work with Mach4? Also I want to add a 4th axis and a spindle with automatic tool changer. Will this work too or do I need a new control board? I bought my CNC with a longer Z travel, so I have plenty of room for these. Thanks!

When did you purchased the VFD and spindle? We only started this after the date of the instagram post that offered this added service.

Additional Information:
I purchased it July 16, 2020 however due to all the 2020 issues, I'm just now completing my CNC and hooking up the VFD and Spindle.

Additional Information:
The service started on Sept 23, 2020. Your order was prior to that.

The soldering is straightforward. If you wish to have me provide this extra service, feel free to send the unit back with the cable and I will solder the cable and do the parameter check and test the VFD and spindle.

Additional Information:
When I purchased my VFD and Spindle, I forgot to purchase the wire for the spindle. I had an electrician run a 220 line and hook up the VFD. But I don't have the wire for the spindle. I'd like to get the one you recommend and just pay you for another connector and the soldering.

There is some variation in the outward appearance of laser power supplies due to sourcing through different vendors. However, the basic wiring requirements are the same in each case. For the unit with integrated laser controller, follow the diagram found here: https://buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx#prettyPhoto/0/. The terminals on the signal side will have a 6 connection terminal block -- these are the ones labeled 5V, IN, G, P (or WP), L (or TTL-L), and H (or TTL-H). The High Power side will have 3 inputs for AC power, one high voltage lead, and one return line. Connect these as shown in the diagram as well: the return line goes on the "front" (beam exit end) terminal of the laser tube, the high voltage lead goes to the "back" terminal of the tube, the FG terminal (or G) receives the earth ground wire of the AC power cable, and the two AC terminals receive the line and neutral wires of the AC power cable (it doesn't matter in this case which wire goes to which terminal).

I just purchased some wire for my 2.2 spindle as per your recommendation it's 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections. However, it's a three wire (black, white and Ground). Which numbers on the female pin connector do I connect the wires to. Cheers.

If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

I purchased the 4.0kw spindle and VFD a while back, and have just installed a PMDX-107 controller... do you have any examples of the wiring connections for the SL-240EE to PMDX-107?

What laser controller model number do you have?

Additional Information:
Hey - the model number on the laser controller is
AWC708C
S/N:708014243

Additional Information:
Thanks for the model number. I am going to fabricate the parts and put it together myself to see the issue. We made this modification to the blackTooth laser cutter to better house the new laser controller that we wanted to add to the laser, but that may have been for the AWC608. If there is an issue with my assembly, we will create a new part that will correct the issue and send it to you.

You can only use the planet-cnc interfaces with the PlanetCNC software. If you like the software and want to remain with that software, the hardware interfaces will need to be purchased from the planet-cnc folks.

I would recommend using the Pokeys57CNC interface which is compatible with Mach3 and Mach4. You can also consider the Mach3 USB interface if the Pokeys57CNc interface is out of your price range.
