  • 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.

  • What wire do I need to power the spindle (ie, from the 220 outlet to the spindle). Would a dryer cable work? Is there specific amperage the wire needs?

    The wire that is connected to the spindle can be a simple extension cord, that you find at a local hardware store. However there is a missing wire that is required(ground) which will have to be the same amperage of the extension cord.

  • On the YL600 VFD which connections are DCM, ACM, V1 & Forward?

    The DCM is DC common, or DC Ground which is used in conjunction with Forward (FWD, or FOR) to start the spindle in the forward direction.

    The ACM is the AC Common, or AC Ground (Alternating current, or in this case, a variable voltage for spindle speed). The ACM is used in conjunction with V1 to provide variable speed for the spindle.

    In order to use the terminals DCM/XGND, FOR/FWD, ACM/GND and V1/VI1, you will need to program the VFD to enable the terminals and disable the control panel.

    YL-600:
    Start/Stop - XGND or COM is paired with FWD or X4 (X5 for Reverse).
    Spindle Frequency: XGND or COM is paired with AI1 and uses a top end of 5VDC

    YL-620:
    Start/Stop - XGND is paired with FWD (REV for reverse)
    Spindle Frequency: GND (not XGND) and VI1.

    The Start/Stop portion of the control panel and terminals is separate from the spindle speed/frequency control panel and terminals. Each of these have a separate programming parameter.

    For the YL-600/620, the P00.01 parameter controls the source of the start/stop function.
    Settings for the P00.01 are:
    0: Control Panel is used and the terminals are disabled.
    1: Terminals are enabled and the Stop on the control panel is still enabled if needed.
    2: Terminals are enabled and the Stop on the control panel is disabled.
    3: Control is sourced from the MODBUS also specified as the RS-485 connection. This would be labeled as RX and TX (Receive and transmit) and uses the UART protocol (serial communication protocol). https://buildyourcnc.com/FAQ/13381 explains this in depth.

  • What are the power requirements for the Blackfoot setup? (https://www.buildyourcnc.com/blackFoot48v40.aspx) Volts & amperage? I would imagine it works from a regular, household 110 volt wall outlet? Thanks!

    The electronics and motors are powered by a 36 volt power supply running a max of 8.8 amps. You can configure the system to run on 110v or 220v.

    Additional Information:
    If you wish to use a spindle (recommended), you will need a 220V outlet. You can still use a standard router and this will consume around 11 amps, depending on the model and power of router that you choose.

    So, you can expect a total consumption of 11+8.8 = 19.8 amps.

  • I get random e-stop while machining. I checked the connections on the redfly and they are OK

    You can increase the debouncing for the input terminals where the limit and e-stop switches are connected. Go to Mach3 and the config menu. Click on General Config... in the config menu. The General Logic Configuration dialog box will appear. On the top right of that screen, you will see Debounce Interval. Increase this number until the problem stops.

    You might also want to check your wiring. You don't want the limit switch wiring close to any motor wires, including the spindle cable. The limit switch cabling should be shielded and the shielding of the cable should be grounded.

  • I purchased the 4.0kw spindle and VFD a while back, and have just installed a PMDX-107 controller... do you have any examples of the wiring connections for the SL-240EE to PMDX-107?

    If you want speed control, it is recommended to use the RS-485 connection on the VFD and use the control program such as Mach3 to communication serially with the VFD using this RS-485 connection.

    If you would rather use a controller such as the PMDX-107 to simulate the effect of a potentiometer using the Aref, Aout and Agnd and the Rev/Dir and Fwd/Run terminals to control operation and direction, you can connect those to the VFD.

    PMDX-107 Aout connects to the VI (analog voltage in). This is like the wiper on a potentiometer.
    PMDX-107 Agnd connects to the ACM terminal on the VFD for Analog common.
    PMDX-107 COM connects to DCM terminal on the VFD for Digital common.
    PMDX-107 Fwd/Run connects to the FOR terminal on the VFD for Forward.
    PMDX-107 Rev/Dir connects to the REV terminal on the VFD for Reverse.

    Refer to your PMDX-107 manual to correctly configure your dip switch settings and make sure to calibrate (tweak) the speed control using the trimmer next to the terminals on the PMDX-107.

  • Where are the limit switch connections made when the switches are in series, and NC??

    One end of the limit switch circuit will be connected to the pin and NC, and the other end will be connected to COM and GND.

    For example: (the "-" is wire.)

    [Breakout board input pin] ---- ([NC on switch] [com on switch]) ---- [NC on switch] [com on switch] ---- [back to GND on the breakout board]

  • 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.

    Additional Information:
    Practically silent. The inverter makes more noise!

  • What are some good ways to control the vertical laser from a Linux machine?

    There really isn't any good way to use Linux when using a traditional Laser Controller. If LaserCAD worked under the Linux OS, then that would work.

    Would you like to know an alternative to use Linux using maybe LinuxCNC? There are ways to do it, but you will find yourself deep in g-code and out of the box wiring configurations, most likely.

    Alternatively, you can create a dual boot scenario and put Window on the other part of the hard drive. This way, you would be able to run LaserCAD.

    You can also "attempt" to use LaserCAD in the wine environment, but I have a feeling that will probably not work.

    Additional Information:
    We're a small family-owned electronics and hardware manufacturer, using LinuxCNC already for milling. Dual-boot into Windows isn't a sensible option -- it would greatly reduce the utility of the machine. I have more information about our use case in https://buildyourcnc.com/FAQ/13985.

    Additional Information:
    Ok, fair enough. Then let's get into the details on how you can use LinuxCNC to operate a Laser machine.

    Do you have an idea what controller you will be using? Parallel?

    Additional Information:
    My first inclination was to use LinuCNC with the parallel interface board. Of that's the answer, then we might want to just add to the LinuxCNC discussion that's starting to firm up at https://buildyourcnc.com/FAQ/13985 rather than duplicate the information here.

    I'm open to other alternatives and am happy to hack; we make PCBs and cable harnesses as a business, so that's not a limitation either. One answer might be to use one of the open source controllers that are starting to show up.

    Additional Information:
    My turn for phone typos. ;-) I meant to say "If that's the answer, then..."

    Additional Information:
    I've started a forum topic about this at http://www.buildyourtools.com/phpBB3/viewtopic.php?f=9&t=8412&start=0

  • 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.
