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?

It is possible to connect and configure the spindle VFD to the mach3 via an RS485 communication and protocol.

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.

HOW DO YOU HOOK UP THE VFD TO SPINDLE?

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.

3: Display input AC voltage. Self explanatory.
4: Display mother line voltage. This will display the actual voltage at the input.
5: Display output voltage. This will display the voltage at the UVW terminals for the spindle.
6: Display speed paragraph number SPx. I believe this displays which frequency is being selected (P07.00 to P07.07, or 1 to 8 respectively).
7: Display inverter temperature. This is the temp of the VFD, self explanatory.
8: Display input signal X1-X3/output signal. This simply shows the inputs/outputs associated with the external terminals.

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.

The DCM is DC common, or DC Ground which is used in conjunction with Forward (FWD, or FOR) to start the spindle in the forward direction.

The ACM is the AC Common, or AC Ground (Alternating current, or in this case, a variable voltage for spindle speed). The ACM is used in conjunction with V1 to provide variable speed for the spindle.

In order to use the terminals DCM/XGND, FOR/FWD, ACM/GND and V1/VI1, you will need to program the VFD to enable the terminals and disable the control panel.

YL-600:
Start/Stop - XGND or COM is paired with FWD or X4 (X5 for Reverse).
Spindle Frequency: XGND or COM is paired with AI1 and uses a top end of 5VDC

YL-620:
Start/Stop - XGND is paired with FWD (REV for reverse)
Spindle Frequency: GND (not XGND) and VI1.

The Start/Stop portion of the control panel and terminals is separate from the spindle speed/frequency control panel and terminals. Each of these have a separate programming parameter.

For the YL-600/620, the P00.01 parameter controls the source of the start/stop function.
Settings for the P00.01 are:
0: Control Panel is used and the terminals are disabled.
1: Terminals are enabled and the Stop on the control panel is still enabled if needed.
2: Terminals are enabled and the Stop on the control panel is disabled.
3: Control is sourced from the MODBUS also specified as the RS-485 connection. This would be labeled as RX and TX (Receive and transmit) and uses the UART protocol (serial communication protocol). https://buildyourcnc.com/FAQ/13381 explains this in depth.
