Comment List
  • Apologies - I had intended to write a response to you but the response was eaten up by site maintenance/outage and I forgot to try answering again.


    I am still awaiting further communications from Infineon. They have provided me with a combined firmware + parameter .ldf file for loading onto the unit which seems to operate but with a number of issues - incorrect RPM reporting, hesitant start-up, audible "clunk" on start-up. The reason why the original parameters did not work still have not been ascertained and they have not provided the parameter selections necessary for generating the combined file. Unfortunately, with just the combined file, testing other modes of operation (e.g. Vsp control) becomes impossible.


    But perhaps the biggest issue concerns programming stability. I was not able to load the .ldf file onto the unit using either one of two Windows 10-based PCs (one AMD, one Intel). The choice of USB controller did seem to make a difference to some degree. I had to pull a Windows 7-based PC out of retirement to get reliable programming and have fed this back in an attempt to have it solved, but it has been a few weeks without a response and it seems 's attempts to follow-up have not been greatly fruitful.


    As for ' suggestions, yes, this fan is designed for up to 60Hz operation ordinarily on AC mains for the maximum (rated) rotation speed. Running it on a VFD such as this kit should allow for synthesising an arbitrary rotation speed (i.e. frequency), although over-speeding at greater than 60Hz is likely to cause safety problems. Throwing in a soft-start and getting steady 3-phase output from the board is not really what the product is about as it is "intelligent" with sensorless field-oriented control which should be able to regulate speed, ramp-up/ramp-down rate and provide some feedback control to regulate speed under load as well. It already has per-phase shunt resistors for measurement of current for the flux estimation and overcurrent protection features (in addition to a thermistor for over-temperature protection). It really seems to be pretty "bulletproof" in its design.


    The PWM frequency can ordinarily be set - higher frequencies are preferable for reducing audible noise from coils but can cause increased switching losses, so it can be customised. However, the reason why the provided incomplete parameter set in the manual and datasheets does not allow the motor to start up is still not determined - the PWM frequency does not affect this much from what I could tell as I did try changing the parameter.

  • Hi ,


    May be this data might help. I'm sure you have read it.


    I think, testing with 1kHz ist not the solution, it seams a wrong measurement.

    I think, this fan is designed for using with 50, or 60 Hz which have to write into the parameters.

    May be it can run with 100Hz, but I think it runs with slower frequency, down to 50,,40,,,or a bit slower Hz, but not more.


    Hmmm. I think for your application with this fan motor is to parameter it with a bus voltage about 300V (325V you get from the one phase rectifier from the power source).


    With 50Hz, 60Hz 3ph output and with these motor parameters then you can make just a "soft-start" 3ph motor switch, and then with PWM you can set the rpm.


    (reading at beginning at the page 30)


    I think you have to slow down the frequency with your application instead of so 15kHz switching frequency, also 5kHz PWM-frequency what you can work with this board.

    An other kind of motor sure it can run faster than this fan.



    A tipp for the first doing: use 3 power resistors (so 180Ohm 1200 Ohm / 100W), set the parameters and step by step go to the given application.

    The resistors can help to measure the high frequencies which you can here easily bring down to the 50Hz for the motor.

    Then you make your application with the fan.




  • Hi,

    Did Infineon solved the issue? Any feedback, promised help from their side?

    If I missed any updates - sorry for confusion but browsing product sites I didn't find updated papers or new resources.

    I still hope we can move on!



  • To all roadtesters,


    I spoke with the sponsor today. They are working though the problem you have described. They are also trying to get another tech resource to help. I would expect there might be some delays. So, I have extended the deadline for the review.


    I'm not sure you can move forward while we are waiting on the sponsor's feedback to the problem.


    I appreciate your efforts and Infineon told me they recognize your efforts and commitment to producing a review.

  • It's smelly even outside, but in Australia, we don't have a choice of colours. As long as it works, I'm fine with it image. I did consider doing the same with wood, but because I have to visit the hardware store by public transport, PVC pipe would have been lighter and more convenient. Definitely not the most conventional of builds for a RoadTest, I must say.


    - Gough

  • I have used a cleaner or heard of a pressure pipe glue. The PVC glue I have used is yellow with ABS being a gunmetal grey. I can appreciate wanting to do the solvent work outside. It would surely stick up the whole house.

  • - Hahaha ... that's a funny way to put it.


    PVC solvent bonding of pipes - the pink is the primer which etches and cleans away the surface in preparation for the solvent bond glue itself. The green is a type of solvent bond intended for pressure pipes which is stronger than the ordinary blue solvent bond stuff which you might see on ordinary PVC downpipe. Of course, being at odd angles, outside in the garden on uneven ground, I couldn't help but have a few drips and splatters as there isn't much time for adjustment once you get the pieces touching together. The solvent bond literally dissolves and reforms the PVC together, making the joint extremely strong and durable.


    - Gough

  • I have to ask about the shades of pink and green. What crayon box did you get the glue from?

  • I did receive a response from Infineon yesterday and I applied their provided parameter file and didn't manage to get it working either.


    I suspect the provided parameter file is not the one they used for testing in the application note and instead I suspect the support person just generated one based on numbers they could find. This suspicion is because of the timestamps of the file, but also because key information such as Ke is set to the "default" value of 36V which seems wrong to me. Perhaps the author of the Application Note would have the parameter file they used - the one we are after and the one that should work. But I also note that their application note Measurement section doesn't show much evidence of the fan running either.


    I have provided a full response indicating some issues with the documentation, showing them my full set-up and the traces from the MCEDesigner monitor that shows it thinks the motor is spinning when it is not.


    I have also been in contact with in discussing how we might be able to get the right help from Infineon. Perhaps if they are willing, I might be able to make some time (even at odd hours) to have a phone call with someone if that could help.


    - Gough

  • Roberto,


    I have been in contact with Infineon. Sounds like there might be something that needs to be updated with their documentation. I will keep you posted about what they say.
