    And i found a thread that seems like it had similar troubles that i measured on my BoB earlier today , showing me very low voltages on the 0-10V output and it looks like the PWMbase is really touching the output voltage

    https://www.cnczone.com/forums/machi...88426-cnc.html

    The following tests were done using a multi-meter connected to the 0-10V output and GND on the breakout board. The VFD was disconnected. The 10V adjust trimpot on the breakout board was set to maximum.
    As you can see, the only factor that affected the output voltage was the PWM Base Frequency settings;


    ((**the last value i have in my settings right now is 50 and this guy measured 62mV on the output and when i had PWMbase at 250 while doing my measurements in a previous post today i was getting 0.225V outputs**))


    Config>Ports and pins>Motor Outputs – Spindle Setup
    PWM Base Freq 4166 (= the highest I can set it to)
    Minimum PWM 5
    S6040 0.01V
    S6041 4.00V
    S12000 4.00V
    S24000 4.00V

    PWM Base Freq 2083
    Minimum PWM 5
    S2999 0.01V
    S3000 2.14V
    S12000 2.14V
    S24000 2.14V

    PWM Base Freq 1000
    Minimum PWM 5
    S1959 0.01V
    S1960 1.08V
    S12000 1.07V
    S24000 1.07V

    PWM Base Freq 250
    Minimum PWM 5
    S1239 0.01V
    S1240 0.28V
    S12000 0.28V
    S24000 0.28V

    PWM Base Freq 50
    Minimum PWM 5
    S1000 62mV
    S12000 62mV
    S24000 62mV

    You need to be looking at your system and not others, you first have to have the 0-10v coming out of the Breakout Board, changing the VFD is not going to do anything

    In MDI M3S12,000 you should see 5v output or close to it once you get this part working then you can look at the VFD

    Have you set the pulleys in general Config. in Mach3 0 24,000

    Yes i did set 0-24k pulley

    I had one of the VFD parameter to 100 hertz and it was just letting the rpm stuck at 3100 rpm . i moved it up and it runs faster but it stays at the rpm when i play with the target in Mach3. Now wondering if it would control the rpm only with a g-code in MDI and not working with the lower right corner of Mach3...

    I am using SmoothStepper ESS in between the BoB and Mach3

    The smooth stepper has to be set correct as well so you have a lot going on, you have to get the output 0-10v working before anything will work correct with the VFD Drive

    Here are the only parameters you need set in the VFD Drive

    Mactec54
    Sunfar300/ 550 1.5Kw / 2.2KwWater Cooled Parameters

    F0.00=3 (Key Pad Potentiometer Control ) ( F0.00=1 0-10v Remote control )

    F0.01=400

    F0.02=1000 (Run/Stop Key Pad Control ) (F0.02=1001 for Remote Terminal control )

    F0.03= 100

    F0.04=400 ( Max Motor Frequency )

    F0.05=5 To 8 ( Adjustable Acceleration )

    F0.06=5 To 8 ( Adjustable Deceleration )

    F0.07=1 ( S-Curve for Acceleration and Deceleration )

    F0.12=400 ( Motor Rated Frequency )

    F0.13=220 ( Motor Rated Volts )

    F1.03=100

    F1.04=400

    F2.00=50

    F2.01=10

    F2.07= 100% ( VFD Max Amps Match Spindle Max Amps Adjust Percentage to Suite)
    ( If VFD Amps are More Than the Spindle Then the Percentage Must Be Adjusted To Suite )

    F2.19=1 ( Number of Pole Pairs )

    F3.13=150%

    thanks alot for the list of important parameters

    i also noticed that probably the ESS is missing something .... my ESS config page is not having the Spindle section i seen in this youtube video .... strange !



    Mine

    I really followed your VFD parameters suggestions and mine is 800hrtz , needed to set it to 2 pairs of poles... it is a ATC JGL-100 2.5kW

    playing with the configs of ESS i managed to be able to control the damn RPM FINALLYYYYY ... i am still a pretty noob with VFD.... wasnt knowing the ESS had to be set , i thought it was just making communication from Ethernet wire instead of just a 1980's printer parralel cables. It might have been a lot of different sources from an error , was good to know where to focus !

    it is reading a bit lower on my tach than the target RPM asked , about 15-20% slower , so 10 000rpm in Mach3 was giving me around 8000-8500rpm

    Something kind of weird is the sound of the spindle is kinda waving just a bit up and down , oscillating , pretty curious . Now using the 0-10V output , will try to use the other pin who is named PWM

    Here i added the check in the PWM and a 250 PWMbase freq , wich i dont know yet what it is supposed to be !






    Here it looks like playing with the PWMbase freq was not really controlling better ( or didnt noticed) but i matched from the ESS spindle menu




    Here i was playing with the Dir and Step Low and at some combination it was sending the spindle to max rpm not controlling it and now this way is working good





    I raised up some freqs settings and the Output mode , not sure it helped ... Checked the Output mode probably helped !




    Added this Enable1 but i dont really know what it is doing and seen it in a few videos so i did it

    So those parameters won't be suitable for your spindle they are for what is written in the header 1.5Kw and 2.2Kw you have to have the right parameters set or you can damage your spindle

    Don't run your spindle with those Parameters

    What are all the motor spec's

    RPM=
    Hz=
    Voltage=220v
    Amps=
    Poles=
