    Default Huajiang VFD H100 and 1.5KW Spindle Speed Control

    I have spent probably 100's of hours already searching reading and attempting to solve my problem.

    Problem Mach3 Breakout board sends 0-10V depending on selected speed 2.5v=6000, 5v=12000, 7.5v=18000, 10v=24000 So I know the settings in Mach3 and the Breakout board is functioning as required. But the speed of the spindle does not match what mach3 is commanding and is being send through the 0-10v to the VFD.\
    I have a laser Handheld tachometer with a sticker on the ER-11 Nut used to verify the speed of the spindle, and is calibrated on known speeds such as belt driven lathe, etc.

    What I have;
    Spindle: Huajiang EYS8043-24/1.50 Air Cooled 1.5KW Spindle (see data plate Pic)
    VFD: Huajiang H100-1.5T4-1A VFD (attached first -38 pages. More can be provided upon request)
    Mach3 Breakout Board - BL-USBMACH-2.22 (https://www.steppermotorcanada.ca/bl5breakoutboard.pdf)

    The function codes I have in the VFD are in the attached spreadsheet.

    Just with a quick look you have Parameter F003 at 120 this needs to be 400 you also need a minimum Frequency F011 this is the slowest speed your spindle can run which with air cooled is most likely 120Hz to 150 Hz

    You also will need to set acceleration time and deceleration time try 6 to 8 for starters

    You also may want to be using V/F as some of these VFD Drives do not work with Vector control with these high speed spindles just something to be aware of

    mactec54, thanks, I have tried both VFD and Vector for the spindle with no change. I had F003 at 400, as well as you suggested in another post but was trying different suggestions. I will try the accel and deccel times and see what that does. I will set the other settings back as you suggest again along with accel/deccel times and see if the speed can be controlled appropriately.

    You should not change Parameters if someone says you should unless they have a lot of experience with these high speed spindles, which most don't

    None of these Parameters will change what has happened to your VFD Drive

    You need the minimum speed set as well F011 this will help so you don't damage the VFD Drive or Spindle

    If you did not see any difference with using Vector mode then you should not use it just stick with F012 V/F=0

    F027=30

    F041=6

    Mactec54,
    I read the Chineseglish manual, and most of it made sense, save for a couple very poorly worded sections. The VFD was not setup to match the spindle as indicated by the seller. So I did my best to fill out the gaps, from what I could find. I believe this VFD is messed it will not respond properly to 0-10v signal for 0-24,000 RPM. I will order a new one and start again. Speed Control via Mach3 is critical to most of my programs.

    Appreciate the help!

    Do I see jumper J3 set to "I" instead of "V" in one of your photos? Of course the VFD will not respond to 1..10V signal then.

    As CitizensOfDreams has said check that all the Jumpers are correct, by default they should of been correct

    Also Parameter F073 in your posted list should be set also F073 =100 if not your speed range will not match your spindle speed

    OK,

    I have set all the parameters as suggested. The jumper was incorrectly set, that must have been my fat finger when I was checking that they were properly jumpered.
    Now;
    F03=400
    F11=120
    F12=0
    F014-F021 = 5/7s (accel/deccel)
    F027=30
    F041=6
    F073=100

    BUT NOW Mach3 will not start the spindle, I was concerned that I killed my spindle without knowing it. I checked the breakout board spindle off = 0.0V SPindle on 24,000rpm = 10.01V So not mach3 or the breakout board.
    So I next tried to set the VFD back to the front keyboard and potentiometer, and manually selected run on the VFD and set 120-400hz and worked properly.
    Now that I know the VFD and SPindle work properly I went back and set;
    F001=1
    F002-1
    Tried to start the spindle from Mach3 again and failed. Did nothing, no reaction for the spindle, but the VFD front screen does indicate 400hz, and when I turn off the spindle in mach3 it does return to 0 but no reaction to the spindle.
    Can you gentlemen see anything that would cause the odd behavior above? I am beginning to think more and more that my VFD is bad out of the box.
    Thanks for your help, I thought I had a good grasp on this but apparently NOT!

    Do you have the FORWARD signal properly connected to the breakout board? Does the signal change when you turn the spindle on in Mach3? Did you accidentally change parameter F044 when you played with the VFD setings?

    So I next tried to set the VFD back to the front keyboard and potentiometer, and manually selected run on the VFD and set 120-400hz and worked properly.
    Now that I know the VFD and SPindle work properly I went back and set;
    F001=1
    F002-1
    Tried to start the spindle from Mach3 again and failed. Did nothing, no reaction for the spindle, but the VFD front screen does indicate 400hz, and when I turn off the spindle in mach3 it does return to 0 but no reaction to the spindle.
    Can you gentlemen see anything that would cause the odd behavior above? I am beginning to think more and more that my VFD is bad out of the box.
    Thanks for your help, I thought I had a good grasp on this but apparently NOT!
    F044 it needs to be 02 for Forward

    J2 you need switched /jumper to NPN

    Something else you may need is another Ground / common for the X1 connection this works sometimes as a 3 wire connection but most need 4 wires as this may be independent isolated connection on your Breakout board

    F044 was set to 02 forward, and it is correctly connected from X!(VFD) to Out1/FWD BreakoutBoard. Yes the breakout board sends 0v off to 10V for 24000 rpm as it turn it off and on, i verified voltage at breakout terminals and VFD terminals. The VFD does react on the front of the VFD to the appropriate HZ setting but it does not energize the spindle.

    J1 is set to NPN so is F067 = 0 - NPN
    J2=VO
    J3=V
    J4=OFF
    J5=X6

    Do you mean another ground in addition to the BOB GND to GND (VFD)? A second wire from GND(VFD) to the ground bus bar?
    The thing is this thing was turning on with Mach3 before, but not controlling speed, now I can not seem to get it to turn on via Mach3 to even see if the setting changes are affecting it or not.

    I appreciate your help! this thing was supposed to be pre-configured to match the spindle, but it was not.... and the vendor was less than helpful.

    UPDATE: I decided to take my breakout board from my Plasma table and connect it here to definitely illuminate the breakout board. It seems I fried this one somehow likely fat fingering that jumper. In any event I have the spindle turning on now. And it does change speed but not as it is supposed to. for example when calling for 10k rpm in mach3 the spindle runs up to 24k, when calling for 4k it runs at 15.8k, when calling for 1k runs at 4k.

    What is your "Config - Spindle Pulleys" look like? Is your maximum pulley speed in Mach3 set at 24000?

    Is the voltage correct coming out of the breakout board? 10V at 24000RPM, 5V at 12000RPM, 2.5V at 6000RPM?

    SOLVED!

    I figured it out and managed to get it calibrated within about 2.5% of set speed and actual speed. I think I can do better by applying linearization.

    I will attach an excel file with my settings for this VFD and BOB using Mach 3

    Mach3 settings;
    Config>Ports & Pins>Spindle Setup/Motor Control Use Spindle Motor Output = Checked / PWM Control = Checked / PWM base Freq. = 2083 / minimum PWM = 0%
    Config>Spindle Pulleys= Pulley Number 1 / Min Speed = 0 / Max Speed = 24000 / Ratio = 1

    Now as for the VFD the problem was in F072-F076 The correct settings are in the excel file attached, but it was the chineseglish that threw me and this VFD has certain lines different that the other Huajiang VFD that is more prevalent out there.

    So it is working properly now, thanks guys for your help in pointing out my jumpers being the base cause of my problems!

    Check the connector on the Breakout Board where the FWD connection is it may need its own common as you do have 5 terminals, The ( 2 ) connections 0-10v and FWD are ( 2 ) different circuits and should have different common returns

    Yes I did meter out each one. And FWD remained unchanged no matter which ground reference I used, for spindle on or off from Mach. This lead me to try the second breakout board. I believe I may have toasted the Breakout board doing this, but seeing as my plasma table does not need spindle control, I put this one in. It works well now. The only problem I have is that whatever Mach Commands the spindle will try to run and will ignore the minimum speed of 6000rpm I set in the VFD settings. So I will need to make sure that my CAM software has a minimum output of 6000rpm.

    The problem is your 0-10v is analog it is not normal to have both using the same common in some cases this can work but is not normal, this may be why you are having this problem can you do a photo closeup of the breakout board terminals may be able to see what they are doing with this breakout board
