  • How to display RPM instead of frequency on the VFD? I have the 2.2kv 110 volt spindle and inverter.

    There is a button on the front of the VFD that will cycle through RPM, Freq, and a few other readings. If there is a >> button on your VFD, that will work. If there is a mode button on your VFD, that should works as well.

    Additional Information:
    There is a >> disc button but it does not cycle through the display modes.

    Additional Information:
    Is there a parameter setting to make this button work to cycle thru the display modes?

    Additional Information:
    setting the starting rpm

    Additional Information:
    the vfd will not start the motor

    Additional Information:
    Any progress on this? I have the same issue.

    Additional Information:
    What model is your VFD?

    Additional Information:
    Mine is a YL620-G-5.5Kw

    Additional Information:
    That model will not be able to show RPM. You will be able to show the frequency, which can be used to determine the RPM. RPM equals the Frequency x 60.

    Additional Information:
    There is an Icon for RPM at the top of the display I cannot cycle through the different options to see the RPM

    Additional Information:
    At the top of my control panel is has 6 different lights which indicate what your seeing. in order from left to right they are COM, ALM, DISP, RUN, Hz, RPM I have seen the ALM light up on initial set up but that was fixes with a parameter change. The run light shows up when i turn the spindle on and and it is running. I am however not able to get any of the other lights to show or to get the RPMs to display

    Additional Information:
    If you do see an RPM light on the display, that panel sticker may be a sticker used for many types of VFDs and the RPM is not used. There is parameter: P00.24 which allows you to pick what to display. The choices a
    re:
    0: Display current target frequency. This will display your knobs, potentiometer, setting, not the actual spindle frequency.
    1: Display electric machinery run frequency. This will display the actual frequency that the VFD is currently sending to the spindle.
    2: Display electric machinery run current: this will display the current the spindle is currently drawing.
    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.
    9: Display user variable. This one I have not delved into, so it may be something to look into.
    10: Display user count value. Same, this one could be useful.
    11: Display temporary debugging variable. Haven't tried this one, so I can't inform of any useful information but it won't pertain to this subject anyway.
    12: Display automatic multisegment run step and time. I haven't delved into this one either, but it won't show RPM.

  • WHAT ELECTRICAL CABLE DO I USE TO CONNECT VFD INVERTER 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 do I conect the VFD of the spindle to the RS485 connections

    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.

    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.

  • What length of wire do you recommend for the black toe (2'x4') between the spindle and VFD?

    The length of the cable from the VFD (Variable Frequency Drive) to the actual spindle should be about the same as the z-axis cable from the z-axis motor to the z-axis driver which is recommended at 11 feet. This is locating the VFD about at the midpoint of the machine.
