Why does my BLDC motor stop during acceleration?

I'm currently evaluating STSPIN32F0 as a solution for BLDC polygon motor control & drive.

My EVB is STEVAL-SPIN3201.

The application is:

• 38V nominal
• 8A max @ acceleration
• 60 deg displaced hall sensors
• 2 pole pairs

My Motor configuration is

When probing for hall-sensors feedback I get:

Sensors 1-3 correspond to channels 1-3 

respectively.

b-emf was also measured:

My sensor configuration is

When measuring b-emf on UVW terminals I get

UVW correspond to channels 1-3 respectively.

When trying to speed ramp to 15,000 in 15,000 ms I get the following UVW drives:

Motor starts spining for approx. 10s and then stops.

MC Workbench displays the flowing data after motor is stopped:

My SystemDriveParams folder & MC Workbench project is attached as a .zip file.

No changes have been made in the source files except commenting out &sharpdefine EXAMPLE_POTENTIOMETER and &sharpdefine FIRMWARE_VERS ''STM32 FOC SDK\0Ver.4.4.2''

Any Ideas?

Thanks,
