Question #: 15144

Question: [Mach3 USB Interface Board] Can you please point me in the direction of a list of VFD Parameters for this to as intended for spindle speed control? I’m using Hunyang VFD. I’ve verified outputs/relays working as intended and PWM signal is correct at the VFD, but its still pulling speed control from the onboard pot instead of PWM signal. I’ve tried every combination of parameters I can think of but no luck.

Current Solution

The HY VFD has three main terminals for PWM control. These terminal inputs are:
- VI for the analog (PWM) voltage input (input at the VFD, output at the controller, i.e. the Mach3 USB controller),
- 10V output (this is an output from the VFD and an input at the controller) serves as the high voltage value for the width of the voltage,
- and ACM the ground from the controller (DCM at the controller)

In the parameters:
- PD002 should be set to 1 (one). PD002 is the source of operating frequency which is the RPM of the spindle in the Hz frequency units. 400Hz = 24000 RPM.
- PD003 specifies the frequency range for these terminals (10V, VI, and ACM) where 10V (voltage reference) is 400Hz and 0v is 0Hz, and VI adjusts the range from 0 and the voltage reverence (10V).
- PD070 selects the voltage range or current range (for use with the AI external VFD terminal as opposed to using the VI). You want to keep that parameter at the factory setting of 0 (zero) 0-10V.

  • [575] I have the wiring and programming and parameters set the same way that you do in the spindle speed control and outputs videos, I can start and stop the spindle with mach3 but can't seem to control the speed. Can you think of solutions?

    Do you have an oscilloscope? You will be able to see the PWM signal and determine if the output is correct. Make sure that you are using the 10V from the VFD as the voltage reference for the 10V terminal on the Mach3 USB controller. The 10V terminal is an input, not an output on the Mach3 USB controller. The 10V is the top voltage signal level that the Mach3 USB controller uses for the PWM signals 100% duty cycle.

  • [575] Hello, I'm wondering if you can provide advice how to wire this USB board where for spindle I would like to use chinese servo motor and driver (TD3) - speed control mode. Especially how to connect - AVI, ACM and 10V (24V is clear). I am still not sure how to power on and off spindle itself. Thank you in advance. Vaclav

    This video should provide enough guidance to understand the PWM signal on the Mach3 USB controller:



    The PWM signal is provided by the AVI terminal, and the 10V terminal is an input and provides the reference for the top voltage for the PWM signal. The ACM is the analog common (analog ground)

  • I am looking at purchasing your 2.2 kw water cooled spindle. I'm assuming it comes with the VFD. I have a rotary phase converter in my shop. Are these spindles 3 phase? And if so, can I bypass use of the VFD and control the spindle speed by the CAM software instead? Or is the VFD an absolute necessity to use on the spindle?

    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.

  • I HAVE A 2.2KW WATER COOLED SPINDLE WITH YL620-H VFD. THE VFD USES P#-## PROGRAM FORMAT. BELIEVE ALL CORRECT SETTINGS SETUP BUT WHEN TURN UNIT ON, IT SPINS AT ABOUT 200-300 RPM REGARDLESS OF WHAT FREQUENCY CHOOSE. DO YOU PARAMETERS IN THIS FORMAT FOR UNIT? THANK YOUR HELP. HUIBERT MEES

    You will need to look for the parameter that controls the run frequency. The frequency can be controlled bu the panel, external terminals, or the RS485 TX/RX terminals (UART protocol). You will want to change that parameter so it uses the panel. If you are referring to the maximum panel dial frequency is only allowing 200-300 rpm, then look for the parameters to control the frequency.

    For 200 RPM:
    Hz = 200/60 = 3.33 Hz

    For 300 RPM:
    Hz = 300/60 = 5 Hz

    Conversion to RPM:
    If you ever find yourself yearning to reverse-engineer the process, the formula is as follows:

    RPM = Hz × 60

    Look for values that match somewhere between 3 and 5 in your frequency parameters and replace them with 400 to give you 24,000 RPM max.

  • I have wired up my 110v VFD and my 2.2Kw spindle and I get an E.Lu.5 code. My wiring is correct and the parameters are set to those for the VFD according to your website I found in a previously answered question from someone here. Any help would be greatly appreciated, thank you!!

    The E.Lu.5 Error code on your VFD is related to Low Voltage.

    The recommended action is:
    - 1. Check whether the input voltage is normal. (the voltage from the wall/breaker to the VFD)
    - 2. Check whether there is a sudden change in load.
    - 3. Check whether there is any phase missing.

    Unfortunately, these three recommended actions will probable require an electrician to test the line going into the VFD.

  • I've buffered a PWM signal to a 0-10V analog signal and I would like to use that signal to run your 110V 2.2kW spindle and VFD. Could you please detail the correct wiring and VFD settings to get that working?

    This will depend on the VFD you have to identify the correct terminal. The terminal on the VFD will be labeled AI1 typically (Analog Input #1). You will also need to make sure to complete the PWM circuit using the GND terminal on the VFD.

    Additional Information:
    I have wired my 0-10V signal to the AI1 and GND terminals as suggested. I have also set the PD-01 and PD-02 settings to 1. Still nothing. Is there something else that I am missing?

    Additional Information:
    Thanks for the information. Can you let me know the model of the VFD that you have?

    Additional Information:
    VFD Model # YL600-2S-2K20

    Additional Information:
    Thanks. I will check our resources and documentation to see if there is another programming setting that needs to be changed.

    Additional Information:
    Does your VFD have a VI terminal?

    Additional Information:
    No, it does not. The terminals for this VFD are as follows (seperated by dashes "-").

    10V-AI1-AO2-PLC-DI5-DI3-DI1-COM
    AI2-GND-AO1-DI6-DI4-DI2-FM-24V

    Additional Information:
    Do you have a PD070 parameter?

    PD070 is the main Analog Input parameter.

    The options for that parameter is:
    0: 0-10V
    1: 0-5V
    2: 0-20mA
    3: 4-20mA
    4: 0-10V (4-20mA Stacked)

  • Hi there. I have an ex school Boxford HSRmi2 sat in my workshop, good condition and I'm assured it's all ok, but I want to rip everything out and go down the Mach 3/4 rabbit hole with servos. I need help at this point as I haven't done anything like this before and have no knowledge of controllers/motors etc. Could someone please point me in the right direction? Thanks.

    If you are wanting to use servos, I would highly recommend using closed loop steppers and drivers. You will get the best features of both the servo closed loop and the exact digital positioning of stepper motors.

    For controllers: the pokeys57cnc will work with either Mach3 or Mach4

  • I'm hooking up the VFD Controller to the USB controller to control the speed of the spindle. In your video you have the wire from the USB controller to the ACM of the VFD controller. The VFD controller I have is a XSY-AT1 model AT1-2200s. It does not have an ACM contact. It does however have a SP1 contact, is this where I land that wire?

    You want to look for the analog input terminals in the wiring diagram in the manual for your VFD. I believe the VFD you have, the XSY-AT1 has three terminals that will accept an analog voltage to adjust the speed. These terminals are:
    COM or ACM - this is where the ACM from the controller will connect
    VI/CI - The AVI will connect to this terminal which is the actual voltage level that will determine the speed from 0 to 10V.
    10V - This connects to the 10V terminal of the controller which will provide 10V to the controller allowing the top voltage reference for the controller. This will provide a 0 to 10V range for the AVI or VI/CI terminals, and if 5V is available on the VFD, then the range will be 0 to 5V.

    The parameter you need to change in the VFD is P10 which will change the source of the frequency, either the control panel which is the default (0 or 1, keys or potentiometer - dial, if that is available on the VFD), External analog signals which are the ACM, VI/CI and 10V/5V terminals in the VFD, or the RS485 which is a serial connection to the computer. You want to set this parameter to the External terminals which may be 2, but check your manual for the proper value.

  • I bought Mach 4 and Mach 3 USB Motion card STB4100. The installation Manual you direct me to is for installing board with Mach3. Where can I find directions for the combination of products I bought? The axis motors are held stationary by the magnets but when I try to jog an axis from mach 4 program, no movement.

    The fact that you cannot move the motors with the keyboard serves as a clue to a couple possibilities.

    - The software may not be communicating with parallel port. (One possibility may be that your step pins are not low active, or vice versa depending on your drivers).
    - You may not be in the correct tab of Mach3. Make sure you are in the Program Run tab.
    - The jog on/off button on the program run screen may not be lit (invoked).

    This address below shows the complete troubleshooting for this type of situation. It will show how to test each pin at the parallel port at the back of the computer and everything else associated with correctly wiring the electronics.

  • Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?

    Fusion 360 is a program that allows you to design in a parametric 3 dimensional environment and also provides a great CAM toolset. Fusion 360 will produce the gcode with the CAM capabilities. The gcode is used to move the machine in various ways in order to mill the material; however, software is needed to interpret this gcode and cause the machine to move according to the gcode instructions. This is called control software. So Fusion is CAD/CAM, and you still need "control". Mach3 is one example of control software for milling and is highly recommended.

    Install Mach3 onto the computer that will connect to the redFly(CNC electronics), then configure the Mach3 parameters for the machine (motor tuning, plug-ins, inputs/output, etc.). Home the machine, load the gcode into Mach3 and the machine will move according to the gcode.

    A word of caution, since you are new to CNC machines, make sure you familiar yourself with the machine and the movements of the machine specific to how the gcode is arranged with respect to the coordinates of the machine. Try with very simple gcode until you get a very good understanding of how the machine will move.

    Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?

  • [575] I want to run a SAKO VFD SKI780 by means of this break out board. On https://www.youtube.com/watch?v=P6xxHj6qYSA is mentioned that the 10V terminal on the BOB is an input connection and that it ha to be connected with an external 10V supply source to obtain a 0-10V PWM signal on the AVI terminal of the BOB. I this correct?

    Make sure to watch this video that I created to correctly connect a VFD to the Mach3 USB controller. Yes, the 10V terminal on this controller is an input. VFDs typically have a 10V output that can be connected to this terminal.

    Additional Information:
    The video is here:

    &t=17s

    Additional Information:
    I have connected the VFD to the BOB and configured Mach3 confirm the video. It works perfect! I have only one question left: In the Spindle setup I entered 200 in the field for the PWMBase Freq. Now I measure a PWM signal at the AVI terminal of the BOB with a frequency of 1000Hz. Should this not be 200Hz? What could be the reason? What do I have to change to obtain 200Hz?

  • I am trying to program my 220 volt VFD and it has locked me out. It keeps flashing and the only parameter I can change is P009. I also keep getting a Er 3 code which means input voltage out of parameters but the input voltage is correct. How can I get back to being able to adjust the parameters?

    Can you tell me the model number for that VFD. Use the "Additional Information" for this FAQ to continue add this information and continue the dialog.

    Additional Information:
    Actually, it's the "submit response" button.

    Additional Information:
    It is the XSY-AT1. AT1-2200S

    Additional Information:
    Ok, let me check

    Additional Information:
    You purchased this VFD and spindle combo in April. Have you been using the VFD until now and it just failed? Or is this the first time you are trying to use the VFD? This will allow me to determine if this is a configuration problem or an electrical issue.

    Additional Information:
    According to the manual, P09 is the parameter needed to unlock the VFD if a value has been entered into P08, the password parameter. If the password value is entered into P08, you will need to enter the same password into P09 to see the value in P08 and access the other parameters.

    Additional Information:
    SOLUTION: If you do not remember the password that was entered into P08, then you can enter the value of 55555 into the P09 parameter and P08 will show the password. Take that value presented in P08 and you will be able to enter it into the P09 parameter and the VFD will be unlocked.

    This customer tried the above instruction and he was able to unlock his VFD.

  • My pokeysCNC board creates and analog signal of 0-10V for 0 to 24000 spindle rpm just like it should from Mach3. However, when the spindle is on, the voltage only gets to about 3.8V for 24000 rpm. It seems like the vfd is drawing more current than the pokeyscnc analog output can produce. It there an easy solution to this problem?

    Do you have the Pokeys57CNC connected to a 24V external power supply?

    Additional Information:
    Yes, a 24V external power supply with the jumper positioned. I'm using the ethernet port so the 24v is the only source of power. I plan to measure the amp draw when I have a chance to see how much the vfd is drawing on the analog out.

    Additional Information:
    Further information. The resistance across the terminals on the vfd is 22k ohms. With an independent 0-10v current source I can run the spindle from 20 to 400 Hz. The PokeysCNC only gets to 3.8v with the vfd attached (and the vfd is at 150 Hz) compared to 10v when the vfd is not attached. The power to the PokeysCNC is steady at 24.18 V, so I'm not maxing out the power supply. Still looking for thoughts on what might be going on?

    Additional Information:
    And the other thing - The measured amperage is 0.17 mA for the 0-10 V signal (which makes perfect sense for 3.7 V and 22k Ohms).

    Additional Information:
    Just to bring finality to this issue - I added a 2.2 microfarad capacitor across the 0-10V input terminal (from signal to ground). This solved the issue. Evidently, it was an electrical noise issue.
