Hi there.

I'm trying to learn FOC SDK using P-NUCLEO-IHM001.
First test's firmware is "STM32CubeExpansion_SPN7_V1.0.0\Projects\Multi\Examples\MotorControl\Binary\STM32F302R8-Nucleo\X-CUBE-SPN7.bin".
It worked(I judged it only just looking rotation of motor).

Second test's firmware is output of project "C:\Program Files\STMicroelectronics\FOC SDK\STM32 PMSM FOC LIBv4.2\Web\Project\MDK-ARM\UserProject\STM32F30x_UserProject.uvprojx".
(Using STMCWB outputs parameter.c/.h files, 3 shunt & 6 pole pair)
It seems success about serial communication, However Over-Current faults occurs in a 1 seconds after push the [Start] button.
I heard PWM sound would gradually get bigger.
(Please check appended screenshot image...)

Stabilized power supply indicated 0.05A, just before stop motor profiler.

So I want to know 3 matters.
1.How Motor Profiler judge current of first sequence.
 *STMCWB setting was default(nominal 2.1A).
2.How can I tune(software/hardware) that range.
3.Why X-CUBE-SPN7.bin was work.
