Question #: 14312

Question: How do you connect a VFD with R S T to 220 power single phase?

Current Solution

The below information is for your convenience; however, please seek the guidance of a professional electrician that is experienced with VFDs and electrical motors of this type.

A VFD (Variable Frequency Drive) for CNC Spindles that have input terminals labeled R, S and T will typically use the R and T for the Black (live) and White (neutral) connections and the PE (protective earth) will connect to ground (green).

Check this image for reference:

With the YL600-2S VFD, we have found that the R and S terminals are used where the R is live and S is neutral. Connect the PE to the green ground connection.

  • Using a Pokey57 CNC and Mach 4 can you tell me how to connect my laser. The laser has three wires.. Ground - 12V Power and PMW.

    Do you have a TL or a TH for triggering the laser? If you power the digital side of your laser power supply with 12V and tie the gnd with the PWM gnd on the pokeys57CNC controller, you may be able to use the PWM on the pokeys57CNC controller. Before you do this, I would suggest that you contact polabs support (http://support.polabs.com/) and ask them if this is possible.

  • What size of wire do you use to connect the VFD to the 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.

  • How can I to connect a signal to turn on a mist in a USB board? Thank you

    You will need a 24V relay to control mist using the Mach3 USB breakout board. The wiring diagram (link below) will show one of the output terminals (O1, O2, O3 or O4) connected to one of the leads of the relay. The other lead is connected to the V+ to complete the circuit. The other part of the relay is used as a switch to control the mist on/off.

  • How do I program the 2.2kw VFD to jog with a Digital Input

    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.

    This looks easy enough, however, the VFD that came with my spindle is made by Huajiang, not a Huanyang. The parameter codes are different and do not line up with the ones offered in this response.

  • How do I connect a Z-Axis touch plate to the Planet-CNC USB interface?

    "Semi automatic" measuring is possible.
    1. Place movable tool sensor (touch plate) on material.
    2. Click "Measure Offset Z". Tool will move down, touch sensor and move up.
    3. "Measure Offset Z" button is still down.
    4. Click "Offset - Current Z" - this will set offset Z
    5. Click "Measure Offset Z" again to release it and restore normal mode."

    The connections to the USB interface is as follows:
    - The spindle is connected to the gnd terminal (which is also connected to the end mill). Alternatively, you can connect the gnd directly to the end mill is access is permitted.
    - The touch plate (movable tool sensor) is connected to the Z-- terminal.

    What will happen: When the end mill (gnd) is in contact with the touch plate (Z--), there will be a connection from gnd to the Z-- triggering this Z-- action and the software will recognize the connection (like a button press, or a limit switch triggering).

  • HEY ! I HAVE PURCHASED A VFD WITH MATCHING SPINDLE 1.5KW AND CONTROL PROGRAM UCCNC. MY INTERFACE CARD IS DB25, THE QUESTION HOW DO CONNECT TO DB25 SO THAT CAN SPEED UCCNC? SINCERELY "CNC BEGINNERS"

    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.

  • What wire AWG can I use to connect the power supply 24v 8.3 amps

    Most of our power supplies allow for a 9 amp current draw.

    For the Neutral, Live and earth ground, wire gauge for that level of current is 14 for relatively short cable lengths. Increase the gauge for longer lengths past 25 feet.

    For the DC 24V output terminals to the drivers, 20 gauge is fine. If the power supply is connecting to only one driver, increase the wire gauge to 14.

  • How to wire the Laser Power Supply with an arduino & GRBL ? (I'm not using a blacktooth laser cutter)

    There is a th or tl on the laser power supply that serves as the trigger on a high or low signal. There is also a potentiometer "in" terminal that will accept a variable signal from 0v to 5v to control intensity. You can use either of these features to fire the laser tube.

    If you have gotten grbl to work, then, no doubtedly, you have the expertise to know the output features of grbl. If grbl allows a pwm output, you can tie this to the potentiometer terminal on the power supply. Otherwise, you will need to use a digital output to control the power supply using th or tl.

  • What else from you shop do I need to connect a #40 Drive Sprocket to my nema23 motor, its not so clear

    You will need a collar or adapter to connect the ID of the #40 sprocket (0.622") and a 1/4" collar with our OD (0.674"). We currently do not have anything in this nature.


    Additional Information:


    Additional Information:
    For a 1/4" input shaft the larger #40 sprocket, seem's pretty large for the 1/4" input shaft. So we recommend using a #25 sprocket and #25 roller chain with our NEMA-23 since it will be more compatible arrangement.
