  • how much does the 2.2kW spindle and the VFD weigh together?

    The weight of the 2.2kW spindle without the VFD (variable frequency drive or inverter) is 11 lbs or 5 kg.

    The 2.2kW spindle with the VFD is 15 lbs or 6.8 kg.

  • What kind of wire should I use between the invertor and 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.

  • I HAVE THE REDFLY SYSTEM AND A 2.2KW SPINDLE - 110V HOW DO CONNECT SPINDAL?

    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.

  • 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.

  • 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.

  • How should I control a plasma torch, spindle and a laser on my CNC machine?

    It will depend on how you configure the machine to use the Laser and plasma. Is the laser on a separate gantry? That will determine the way you will connect the laser control system or if you use a typical CNC controller. The plasma will need inputs of THC on, THC up, THC down and outputs to trigger the plasma torch. I recommend the Pokeys57CNC for the plasma and you can also fire the laser with it, but you will not be able to do engraving with the laser unless you use a laser controller. If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using, or if you have the laser on a separate gantry, you can use a traditional laser controller connected to the stepper motor drivers on that gantry.

    Users response:
    I was planing on using same gantry, and installing plasma and laser module on z axis along the side with current router. Perhaps if it’s needed installing another z axis on current z axis. So that when I use plasma, router z will be homed and plasma z axis will be able to utilize thc.

    When you say “If you use a laser controller, you will need to either build circuitry to switch the digital signals from which controller you will be using,”
    If i install laser controller, pokeys and router motion card, do you mean all ( axis and router/laser/plasma) signals or just the one that controls router/laser/plasma?
    I was wondering if I could jump (parallel connect) axis signals from card to card without ?
    Also do you prefer ethernet card or usb?
    I really do appreciate your help :) thanx again.

    Buildyourcnc response:
    Not a problem at all.

    Remember that with all of that weight on the z-axis, you will not be able to do efficient raster style engraving.

    By putting the laser on another gantry, say at the far end of the table, then you would be able to use a laser controller that controls its own stepper motors and the nozzle can have fast swing motion for engraving. With the laser on the z-axis of the spindle (like see on the greenBull), you will only be able to do vector motions for the laser.

    You can also have a CNC interface and laser controller controlling the same stepper motor drivers, but you will need a few tri-state buffer chips where you can use a toggle switch for which controller has control of the drivers.

  • What are the noise levels of the 1.5 Kw and 2.2Kw spindles?

    The noise level of the 1.5 kW and the 2.2 kW are very similar. The noise level is considerably quieter than typical routers. I am going to add sound db levels to this FAQ a bit later.

    Additional Information:
    The db (decibels) reading for the spindle is 70 and an 890 Porter Cable router (a lower powered tool than the spindle) measured 90 db. Both measurements were taken in the same environment and measured at the same distance from the tool.

    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 should I wire the E-stop button? NC or NO?

    I would recommend wiring the E-Stop to an input terminal via an NC connection. This is the industry standard. It requires a NC (Normally connected) circuit for the machine to be operational, and when the circuit breaks, the machine shuts off. This is better than having a circuit NO (normally open), open circuit that requires a circuit to be created to have the machine shut off for safety.

    Having en E-Stop run through the mains line would only work for a single circuit (or use multiple E-stops, which defeats the purpose). The E-stop connected to the input terminal would shut off all machine functions.

  • 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.
