Evaluation Type: Development Boards & Tools
Did you receive all parts the manufacturer stated would be included in the package?: True
What other parts do you consider comparable to this product?: Inverters for low power motors; DesignDRIVE Development Kit IDDK v2.2.1 by Texas Instruments
What were the biggest problems encountered?: Unfortunately - many In my opinion documentation although clear and quite voluminous doesn't give enough support the roadtested kit. Despite many attempts, the motor cant be run using the driver board. The software isn’t stable. - Above issues, adding the awareness of dealing with high voltage made the work truly risky.
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
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

The best course book for this board is: EVAL_DRIVE_3PH_PFD7 Getting started guide.
and useful video: 'How to get started with iMOTION™ 2.0 | Infineon'
unfortunately as you find in my next words, it wasn’t sufficient enough to conduct me to the successful end of roadtest.
Some theory for understanding 3 phase network principles is required.
Delta for connecting to the inverter module
Star when conecting directly to 3X400 net
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
The next step was to prepare software environment

Software setup - download sequence
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)\
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
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
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
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 <<<<<<<<<<<<<<<<<<<<<<
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
??????????????????? Festival of disappointments began ??????????????????????????????????????
The process froze, the MCEDesigner stopped responding, moreover blue LEDs on the inverter board went off
iritating messages apeared
??????????? 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
I tried to load that file - just in case...
it was wrong way...
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.
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.
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,
I'm not a procrastinator by nature. When a RoadTest kit arrives I tend to drop other stuff to go have some fun. The RoadTest opens up a world I rarely get to explore.
I like getting my post out early because I can pose unanswered questions in the hope a follow-on review might stumble on the answer. I confess being late to the RoadTest review rodeo leaves me feeling like I'm duplicating others work. I like the readers to get fresh produce and not the stuff they have already seen. There has been times when I wish I had been last out of the gate. Especially when there are issues with software or hardware versions that create unnecessary struggles and dampen enthusiasm.
If I come across a gotcha and have an immediate fix I like to post that. I hope the share helps others avoid experiencing the frustration by knowing there is a possible fix. The pooled knowledge from a RoadTest Review is a treasure trove of experiences. Those wonderful jigs or work arounds leave me in awe and some peoples brain capacity for solving problems. I'm left with "Why didn't I think of that?" Now I ask questions just in case I didn't think of that:)
I recently installed a inverter/converter/charger in a travel trailer. It was a scratch build. Those printed circuit boards in the inverter had some pretty hefty terminal lugs mounted to the PCB's for the #8 power cables. Seeing this test board needing a soldering iron to install cables got me to thinking, hey a test board would have cables cycled a lot more than an inverter install. I acquiescence that there are a number of reasons to not provide mounting terminals. A large part of my many careers was installation. Pissing around trying to make crap work out of the box because a manufacture scrimped on simple details has made me hyper sensitive to short comings.
For an honest question I wanted to answer honestly, and simply.
The delivery of my set was delayed terribly, resulting, one of us started to publish the report before I could get acquainted with the set at all. Then I found his solution with terminals very handy (exactly as mentioned by you). My first though was to use that idea but then I realized that I would be uncomfortable stealing a concept.
On the other hand, the solution from the guide, with soldered wires isn’t so bad. (I try to remember that sometimes better is the enemy of good one) . That way I can move aside connectors or terminals any distance from the board.
I have had my share of RoadTest equipment that have caused no amount of grief and frustration. It only compounds the problem when they provide encyclopedia quantities of documentation but none of it useful.
I'm going to ask a stupid question but why not provide terminal lugs where the motor connects? To me it would seem appropriate to have a solid terminal lug with a screw to make the connection. It less than ideal to have you solder a wire. Maybe there is something I'm missing?
I know how frustrating some of these early device releases can be.
Your pain will hopefully spur the manufacturer to take steps to improve the documentation for a smoother demonstration of the capabilities.
Another reviewer faced the same problem. But now I can see how roadtests can help manufacturers in getting their products tested before releasing them in the market.
