10 Lab overcurrent problems

Other Parts Discussed in Thread: DRV8305, MOTORWARE

Hello!

I use InstaSPIN-FOC to spin a BLDC motor.

I have done ID procedure (lab2c) and spin the motor using the lab5b, everything works fine but I can't reach the max RPM (6500).

When I increase USER_MAX_VS_MAG_PU to 2/3 it works fine and RPM goes up to 6500.

In the comment it says "Set USER_MAX_VS_MAG = 2/3 = 0.6666 to create a trapezoidal voltage waveform. Current reconstruction will be needed for this scenario (Lab10a-x)." so I move to lab10a to use current reconstruction but in this lab when RPM goes high drv8305 triggers overcurrent fault and when I disable it MOSFETs burn out. What can cause the problem here?
