    Introduction

    It would be impolite to start from complaining without thanks for selecting me for the roadtest.

    Thank you Element14, thank you Infineon for invitation and trust.

    On the other side, I have to admit, the roadtest was full of challenges but also disappointments. I don't want to complain too much and feel sorry for myself but it was the most frustrating roadtest.

    Nevertheless, let me move to the beginning

     

    Unboxing and documentation

    After a long delay caused customs clearing issues, the board with the debugger and finally also the fan were successfully delivered.

    At the beginning everything seemed to be perfect. In addition to devices I was provided with a report from the individual test of my board.

    I prepared for the roadtest surfing infineon sites with documentation of our kit, looked at foras where users share impressions and remarks concerning imotion solutions etc.

    I was sure of good support, clarity and mostly safety first - as I planned to deal with a 3X400 AC net.

     

    Main components of the driver board

    the heart: IMC101T-T038

    iMOTION™ motor controller with Motion Control Engine

    PMSM/BLDC motor controller with integrated script engine

    iMOTION™ IMC100 motor controller with Motion Control Engine (MCE 2.0). The IMC101T-T038 is a flexible control solution for variable speed drives.

    It performs sensor less field oriented control (FOC) for a permanent magnet synchronous motor (PMSM).

    The integrated script engine (small virtual machine) provides application flexibility by running customer scripts.

     

    2ED28073J06F 600V EiceDRIVER half-bridge gate driver IC

    https://www.infineon.com/cms/en/product/power/gate-driver-ics/2ed28073j06f/

     

    600 V half-bridge gate driver IC with integrated bootstrap diode with typical 0.02 A source and 0.08 A sink currents in DSO-8 package for driving MOSFETs including fast body diode CoolMOS PFD7 super junction MOSFETs and IGBTs.

     

    The 2ED28073J06F is a high voltage, high speed power MOSFET and IGBT driver with dependent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction.

    The logic input is compatible with standard CMOS or LSTTL output, down to 3.3 V logic. The output drivers feature a low di/dt output stage optimized to drive CoolMOS™ PFD7 in motor drive applications.

    The floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high side configuration which operates up to 600 V.

     

     

     

     

    IPN60R1K5PFD7S 600V CoolMOS MOSFETs

    https://www.infineon.com/cms/en/product/power/mosfet/n-channel/500v-950v/ipn60r1k5pfd7s/?redirId=144630

    Complements the CoolMOS™ 7. The IPN60R1K5PFD7S in a SOT-223 package features RDS(on) of 1,500mOhm resulting in low switching losses.

    The 600V CoolMOS™ PFD7 SJ MOSFETs come with an integrated fast body diode ensuring a robust device, reducing bill-of-material.

     

    This product family is tailored to ultrahigh power density as well as highest efficiency designs. The products primarily address ultrahigh density chargers, adapters and low-power motor drives.

    The 600V CoolMOS™ PFD7 offers improved light- and full-load efficiency over CoolMOS™ P7 and CE MOSFET technologies resulting in an increase in power density by 1.8W/inch3.

    unfortunately as you find in my next words, it wasn’t sufficient enough to conduct me to the successful end of roadtest.

     

     

     

     

    Theory

    Some theory for understanding 3 phase network principles is required.

     

                          star                                          delta

     

    Delta for connecting to the inverter module

    Star when conecting directly to 3X400 net

    L2−L1=230V∗√2∗(sin(ωt+120)−sin(ωt))=230∗√2∗2∗sin(60)∗cos(ωt+60)=230∗√2∗√3∗cos(ωt+60)

    α=ωt+120

    β=ωt

    ω=2∗Pi∗50Hz∗t

    230∗√3≈398.37 [V]

    maks. 230*1.73*1.41=561 [V]

    In manuals I found interesting option

    Speed control potentiometer connector

    unfortunately I was not able to employ that convenient solution

    Software

    The next step was to prepare software environment

     

    Downloads are available from the site: https://www.infineon.com/cms/en/product/evaluation-boards/eval_drive_3ph_pfd7/

     

    Software setup - download sequence

    1. MCEWizard  (configure the parameter for the motor control.)
    2. MCEDesigner  (load  the file generated above)
    3. IMC101T-T038 MCE software package installer (containing “Firmware”: .irc file)

     

    First I had to download drivers for the debugger - J-Link.

    I decided to install the full package from Segger.

    After inserting the debugger it was properly recognized and required drivers installed (WIN10)

     

    Installation and use of

    MCEWizard (configure the parameter for the motor control.)

    C:\Program Files (x86)\

    iMOTION2.0\MCEWizard_V2.3

     

    our device is IMC101T

    Then I had to fill motor parameters step by step [questions]

    some are simply available in datasheet AC axial fan A2D200-AA02-01

    https://www.farnell.com/datasheets/2143382.pdf

    Motor  M2D068-CF02-07

    https://pl.mouser.com/datasheet/2/120/Ebmpapst_06282016_M2D068CF0207-ENG-1165278.pdf

    A2D200-AA02-01

     

    nominal current=   260mA

    and the first surprise  ??? 4 or 2 ????

    I tried both unfortunately without success...

    Is that measure available indatasheet ?

    in the theory - according to the papers of similar motors it is 150 or 17ohm

    [...]

     

    Now prepare the parameters file

    A2D200-AA02-01.mc2

     

    Now install and run:
    MCEDesigner (load  the file generated in MCEWizard )


     

    Run MCEDesigner, at the beginning open the configuration file.

    According to the guides and supporting video it should be in the nevest "firmware" file

     

    IMC101T-T038 MCE Software Package v1.3.3

    first surprise...

    my fault I forget about setting the right COM

     

    But unfortunately correction the communication port wasn't enough

    These steps aren't described in guides and manuals. Unfortunately, from this point I encountered many difficulties with initial setup and run of the set.

    The roadtest review was delayed and unfinished.

     

    >>>>>>>>>>>>>>>>>>>>> look for IMC101T-T038 documentation <<<<<<<<<<<<<<<<<<<<<<

     

    https://www.infineon.com/cms/en/product/power/motor-control-ics/digital-motor-controller-imotion/imc101t-t038/#!tools

    let's "downgrade"

    still wrong!

    as written in the message, only V1.02.01 is correct

    use available test of connection

     

    Now use MCEDesigner for program the controller

    in the "FIRMWARE" file it is also .ldf file

    use the parameters txt file prepared before in MCEWizard

     

     

    Now start

    Frustration

    ??????????????????? Festival of disappointments began ??????????????????????????????????????

    The process froze, the MCEDesigner stopped responding, moreover blue LEDs on the inverter board went off

    iritating messages apeared

    or:

    ??????????? Did I brick the debuger or the inverter module or both...  ?????????

    And one notice!

    In my opinion from the point of safety that is serious issue

    without LEDs shining the board looks as unpowered...

    >>>> BUT WE HAVE THERE 230AC onboard!!!

    it may be truly dangerous!

     

    After some attempts unplugging, plugging again the set ...at last... programming went successful.

    still some errors appear

     

    ????????? IMC101T_V1.03.03_Default.map??????????

    I tried to load that file - just in case...

    it was wrong way...

    also that:

     

    No documentation nor foras nor even infineon support helped and solved the issue.

    The parameters file contains some errors or MCEDesigner can't use it properly.

    I ended up with program parameters unable to start spinning the motor.

    Only the soft noise and nearly imperceptible twitching

     

    Regarding the MCEDesigner program and its powerful programming and visualization "laboratory"

    indeed, I was able to see many parameters.

    But the program looks unstable. Sometimes I was unable to run charts, sometimes it went good.

     

     

    Does this fan work at all?

    Finally I decided to check the motor run connecting it directly to mains.

    Remembering from datasheet, that in my case only star connection is allowed.

    LETS MOVE!

     

    Instead of summary I decided to stop the report here

    I still hope to get necessary information or konowledge to program the inverter properly and got the motor spinning and controlled.

    My roadtest isn't finished!

     

    Sorry if i disappointed someone by giving up now,

    Marek
