B-G431B-ESC1 FOC does not work correctly

Hi friends. Help me figure this out.

Am I missing something, or is my board faulty?

MCSDK 6.4.1

Motor 12n14p

 

 

In 6-step mode, the motor operates correctly, and the phase signal waveform also appears normal.

But in FOC mode, something strange happens; the motor is practically impossible to spin. In the profiler, it usually starts on the first try, and the program allows you to save the motor parameters, but the motor spins noisily, and profiling a second time in the same session is impossible; the motor won't start. A default project created with the motor parameters from the profiler also fails to reliably start the motor in the Pilot program.

Shouldn't the signal in FOC mode look like a sine wave?
