It is not necessary to connect the spindle VFD (Variable Frequency Drive also called an Inverter) to the computer or CNC motion electronics. The VFD can be controlled independently using the control panel on the VFD. The control panel has the ability to control all aspects of the spindle including Speed, Torque, limits, etc. However, you can connect the VFD to the computer so the CNC control program can control the spindle during the CNC Machine operation. You will need to connect the VFD to the computer via a serial conection (in this case, it is the RS-485 protocol).

The following are instructions on how to connect the VFD to Mach3 via this RS-485 serial connection.

The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

You will also need to download the Microsoft .net 3.5 framework and install it: https://www.microsoft.com/en-us/download/details.aspx?id=21

Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
- PD001 - value 2 - Enables with communication aspect of the VFD
- PD002 - value 2 - Enables frequency control from the communcations port
- PD163 - value 1 - VFD address
- PD164 - value 1 - Baud rate of 9600 (speed of the communication)
- PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

Copy the dll file to the PlugIns folder of mach3.

Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

When you install Mach4 and use the Pokeys57cnc, you will use the plug-in provided by Polabs.

You can get this plug-in here:
https://www.poscope.com/product/pokeys57cnc/

The Pokeys57cnc has a 0-10V output pin (a pulse width modulated (PWM) output pin) labeled onthe diagram as pin 17. You can see this pin at the top of the diagram here:
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

In Mach4, you will need to set the spindle speed output top this pin #17. In the plug-in, set this pin at 10kHz.

You can use one of the terminals on the input side of the breakout board to connect the e-stop switch.

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.

Yes, all of the spindles come with collets. The collets have a 1/4" (6.35mm) bore for end mills that have a 1/4" shank. The ER specification is different for the 1.5kW (ER-11) and the 2.2kW (ER-20).

We have manuals for the VFD rather than the spindles. Can you specify what issue you may be having so we can help you better?

Additional Information:
I am having trouble wiring the VFD. (From the wall outlet to the VFD) I think the manual or setup guide on your website is wrong. The two diagrams show two different sets of terminals on the page.

Also, do you have a video or other documentation on programming the VFD? Your videos and documentation looks like it only covers the 1.2kw version. Are the two different spindles from different manufacturers?

The greenBull can range is routing width sizes of 5 feet and 6 feet. The blackFoot has a 4 foot routing width.

Previous Solution:
The greenBull machine has a sturdier gantry than the blackFoot, so you can be more agressive with the cutting feedrate (cutting speed). The blackFoot is also a good machine, but it all comes down to the speed at which you want to produce the fabrication

The spindle is also highly recommended for it's quietness and easier cleanup (no fan blowing the dust in the air)
