I WIRED MY VFD (2.2KW VERSION) AND TRIED TEST RUNNING THE SPINDLE. CONFIGURED TO YOUR SPECS ON THIS WEBSITE, ONLY ISSUE IS WE GOT AN ERROR CODE. ERR 02, DO YOU KNOW WHAT IS? OR HAVE A LIST OF CODES? THANK

You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

For 200 RPM:
Hz = 200/60 = 3.33 Hz

For 300 RPM:
Hz = 300/60 = 5 Hz

Conversion to RPM:
If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

RPM = Hz × 60

Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

[77] Hello. I’m interested in buying a water cooled spindle and VFD. I have an Avid Pro CNC and would love to control it using Mach 4 but I keep hearing it’s difficult to integrate. Also, is the water pump 120 or 240? I’d love any advice etc. eBay is a web of confusion with all of the options. Thank you.

If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.

I have a 2.2kw water cooled spindle with a YL620-H VFD. The VFD uses the P#-## program format. I believe I have all the correct settings setup but when I turn the unit on, it spins at about 200-300 RPM regardless of what frequency I choose. Do you have the correct program parameters in this format for this unit? Thank you for your help. Huibert Mees

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.

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.

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?

You may want to try using a ferrite core or an inductor in addition to the shielded cable. Also, make sure you are grounding the shield at both ends. Even though this is not high frequency, grounding the shield at both ends in a motor scenario may help. Also, try to reduce any parallel wire runs.

The KL-4030 is a Keling 3.0 amp stepper motor driver. These are generally pretty robust drivers. You mentioned in the question that it worked for one hour. This sounds like it could be a contact issue with the wiring in the terminals. I would recommend that you check all of the connections. The terminals that are used in these drivers have terminals that are easily used incorrectly.

Make sure to open the terminal all the way using a small screw driver. Then insert the exposed wire into the opening and re-tighten the terminal. Make sure of a good connection by tugging on the wires.

Also, check kthe digital wires that connect from the driver to the control board.

The 12V power supply has 3 terminals for AC in: N, L and earth ground. The output of the 12V power supply has 2 DC + and - terminals. Cut the connectors off of the ends of the fan and pump wires. Strip the red and black wires of both units. The fan will connect to the 12V power supply red to the + and black to the -. The pump will connect in the same way, but the white is not connected.

If you have a pump that has a grey and black wire on the large connector, the grey is the 12VDC V+ wire and the black wire goes to the V-. The extra wire does not need to be connected.

To control a spindle using the USB CNC interface, you will need a relay board that contains a transistor that can activate the relay with a power source with enough current that can activate the relay. This video explains all of the information you will need to develop this relay circuit:

Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

There is no specific manner in connecting the water lines to the spindle. No specific output and input locations, only the diameter which we use is 1/4 Inside Diameter and 3/8 Outside Diameter (you might find another one that works just as well).
Unscrew the 2 hose nuts and feed the tube through (will be snug), and adjust the tube on the hose fittings and screw the hose nuts down. Feed the tubes through your machine towards the water bucket, making sure it will not get caught on any moving parts and cause a jam/leak, and fit one tube to the outlet of your water pump and leave the other tube to the bucket as a return line. (unless you are using a cooler like a radiator, then feed it to the outlet of the radiator and to your water pump)
