Start-up failure FOC SDK

Hello!

I used STM32F103C8 + STEVAL-IP05F and I was able to run successfully.

Now, I developed my PCB, in which I took STM32F072C8 and STGIPQ3H60T-HZ.  I used FOC4.3.

 

When I try to start, after running a speed ramp, I always get a Start-up error. I did everything that is described in FOC FAQ, but the error has remained. I reduce very strongly the coefficient of G2 to 1000 otherwise I get the erro Speed feedback.

 

I got oscillograms when I overclocked the motor and I think they are normal. I observe that after several starts the engine is very hot. It seems to me that the FOC does not correctly calculate the current values

 

Thank you very much,

Artem
