The motor speed is out of control and runs to maximum speed

The software path I used:  D:\ti\controlSUITE\development_kits\DRV8312-C2-KIT_v128\BLDC_Sensored

Hardware：DRV8303EVM  

#define LEVEL6  6           // Verify the closed speed loop and speed PI controller.

I changed the IO port configuration according to the DRV8303EVM hardware.     #define   BUILDLEVEL LEVEL6

The motor can start normally, but the speed is not controlled, and the motor automatically runs to the highest speed. How to solve this problem?
