Question #: 13544

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

Current Solution

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 does it mean when my spindle VFD inverter shows OC-2?

    Remember, steps to correct and troubleshoot issues with any electrical devices should be done by a professional electrician.

    If you have an HY series VFD, the fault codes are below:

    OC-1: Over-current during ramp up or over-current at constant speed.
    Recommended actions: 1, 2, 3, 4

    OC-1: Over-current during ramp up or over-current at constant speed.
    Recommended actions: 1, 2, 5, 6

    OC-2: Over-current at deceleration or over-current at stop.
    Recommended actions: 1, 7, 2, 9, 10

    dL: Output short circuit.
    Recommended actions: 11, 1, 10

    Ou-1 or 2: Over-voltage at stop, over-voltage at acceleration, over-voltage at constant speed or over-voltage at deceleration
    Recommended actions: 12, 13

    Fb: Fuse break.
    Recommended actions: 14, 10

    Lu: Low voltage.
    Recommended actions: 15, 16, 17

    OH: Over heat of inverter.
    Recommended actions: 18, 19, 20

    List of recommended actions:
    If error shows at ramp up or at constant speed:
    1. Check for a short circuit or partial short circuit and the insulation of the output wire is sufficient.
    2. Increase the capacity or the inverter if it is too small. Replace with an inverter that has a larger capacity
    3. Extend the ramp-up time
    4. Decrease the torque and increase the set value.
    5. Check if the motor is blocked and if there is a sudden change in load.
    6. Check if there is a sudden chance in the power supply voltage.
    7. Extend ramp down time
    9. DC breaking is too high. Decrease DC breaking
    10. Replace the inverter.
    11. Check to see if there is a short circuit with the connection wire of the motor.
    12. Extend the ramp-down time or add a breaking resistor.
    13. Check the mains supply voltage and insure there isn't ant sudden change in voltage.
    14. Send the inverter for repair.
    15. Check whether the input voltage is normal
    16. check whether there is a sudden change in load.
    17. Check whether there is any phase missing.
    18. Check the fan in the inverter. Is it spinning? Is it blocked? Does it have any foreign matter stuck on the fins of the fan? If so, clear the fan.
    19. Check the ambient temperature in the space that the inverter is placed.
    20. Check for adequate ventilation for the inverter where it is placed.
    21. Check for jamming or any sudden change with respect to mechanical load.
    22. Set the V/F curve correctly.
    23. The motor is too small.
    24. The motor is hot and the insulation of the motor degraded.
    25. Check if the voltage has a large variance.
    26. Check if there is a phase missing.
    27. Contact the supplier

  • 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.

  • How do you connect the spindle VFD to the parallel breakout board

    Change PD004 base frequency to 400hz
    Change PD003 Main frequency to 400hz

  • What wire size to use from VFD to 2.2kW spindle?

    We use 16 AWG wires between the spindle and the VFD. This wire size has a maximum capacity for 22 Amps, a good buffer to eliminate any possibility for overheating. The 2.2kW using 220V may draw up to 10 Amps (220 x 10 = 2200).

    That is, all three wires are sharing the total current draw.
