I suppose you are trying to determine how to connect the VFD tothe relay on the breakout board. This is possible, however, not recommended as there is a more robust way to connect the VFD to mach3 or mach4 that allows that CNC machine control software to control the speed and other features of the VFD.

Follow the instructions from this question (number 13383):
https://buildyourcnc.com/FAQ/13383

To get to this answer, you can also ask this customer service "How can I connect my spindle's VFD to mach3?"

Additional Information:
If you still want to connect the VFD through the relay, I will clarify this instruction on this question tomorrow as I don't have the information in front of me at this moment. Thanks.

WHAT TERMINALS ARE USED TO CONNECT THE INVERTER WALL OUTLET?

The blackTooth build instructions explain how to hook the four LED control panel to the USB breakout but not the Parallel BOB. Turns out it's very easy. Simply wire the corresponding LED cathodes (top pins on the display) to the matching CP- for the X, Y, and Z axises and wire the anodes (bottom pins) to the 5V terminals. For the on/off LED, wire the cathode to the G terminal on the laser power supply and the anode to the 5V laser supply terminal. Also, remove the 5V wire running from the Parallel BOB to the 5V terminal on the laser power supply. It is not needed and will cause the laser on/off light to always be on if the USB cable is connected.

Change PD001 Source of Run Commands to '1'
Change PD005 Max operating frequency to 400hz
Change PD004 base frequency to 400hz
Change PD003 Main frequency to 400hz
Change PD006 Intermediate frequency to 2.5
Change PD008 max voltage to 220v
Change PD009 Intermediate voltage to 15v
Change PD010 Min voltage to 8
Change PD011 frequency lower limit to >100hz (120hz to start)
Change PD142 7 Amps
Change PD143 2
Change PD144 3000

Note: PD001 had to be changed back to 0 to allow for keypad control.
Note2: I had to reverse U and V to get the spindle to go forward in FWD. (reverse any two wires, u&v or w&v for example)

HOW DO YOU SETUP THE SPINDLE INVERTER?

The type of wire that should be used between the spindle and the VFD (Variable Frequency Driver also called the inverter) should be of stranded type and we use between 18 and 16 AWG.

The total current is divided among the three coil wires, therefor a wire gauge of 16 should be sufficient.

Currently we use 20AWG 4 conductor.

WHAT ELECTRICAL CABLE DO I USE TO CONNECT VFD INVERTER SPINDLE?

The blackFoot CNC machine kit does not include a table. The table can be made as long or shot as you need. for instance, if you are looking for a travel of 4 fet x 4 feet, then the table will need to be about 6 feet long to get the full 4 feet of travel.

The electronics are very straight forward using the connection diagram for the breakout board that you select. Use the videos for a general idea and then use the connection diagram to verify the correct connections for the interface of your choosing.

Yes,the USB interface replaces the breakout board, but remember that you will need to use the planet-cnc software with the USB interface.

Additional Information:
The electronics does accompany the cnc machine kits as long as you select the option "with electronics". There are option to purchase the machines without electronics and that would be necessary if you either have your own electronics, or you prefer the plug and play cnc computer system we call the redLeaf, or redSprout. This will also be necessary if you prefer the electronics that use the USB interface rather than the parallel interface.

The Mach3 USB board found here: https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Is not designed to work under Mach4. The Mach3 USB uses a plug-in in Mach3 to function as an interpreter, sending pulses and signals to electronics from commands sent to the board from Mach3. This plugin would need to be updated to be able to work under Mach4 but the board manufacturer would need to do this update. So far, there is no plug-in that will work for Mach4 and this board.
