Dear SJunt

You have not received answer because you have fill your question to strange place.

This Community channel was created for Q&A after ACIM solution webinar dedicated for EMEA and US region.

This is not standart support channel.

Please use OLS system (https://my.st.com/ols) 

May I have a question? How you have found this Community channel?

(please check if you well done all requested modification for FOC and MP (Motor Profiler) support. Not all motors can be tuned by MP a specially if motor do not fit to Power Stage parameters or if it not tested at nominal motor conditions please check od modify filled/used speed, current, voltage)

Have a nice day.

Ondrej

Thanks for answering me, I've been waiting for an answer for days on my problem.

So how do I contact support channels?

[Ondrej HOLY]

Please use OLS system on following link https://my.st.com/ols.

[somkid]

what is this

[Ondrej HOLY]

It is Online Support System.

If you enter a question there a ST expert answer it. 

[somkid]

I think I answered that point but the help is still unanswered and the answer is still the same.

There is a design fault on the IHM08M1 (at least on the 3 units I have) where the switch-mode converter does not start when Vbus is greater than about 12V. The output from this switch-mode drives the output driver enable signal, so there is not FET drive when Vbus is more than 12V, hence the test never works. This may not be the cause of your problem, but it is a good place to start.

[somkid]

I ran into that problem.Troubleshooting is very difficult.Doesn't work as intended

[jartim]

I tried to fault-find the circuit but it is almost impossible without any of the original design information. I ended up having to run my motor at 12V only during development then I will move to a custom board for the final product.
