TMS320F280025C: encountered issue when using DRV8300 to drive motor

Part Number: TMS320F280025C

Hi Team,

This is the solutions my customer use:

The motor rotate stable during LEVEL_2 open-loop. But shaking during LEVEL_3, over current error was raised simultaneously.

This is the waveform of angel signal. The purple one is the angel signal which is generated. The yellow one is observed.

Thanks & Regards

    Please follow the lab user's guide to verify the current sensing in build level 2 again and set the correct sign for the current sensing with ADC. If you want to verify the angle of the estimator, you need to make sure that the motor parameters are set correctly and the voltage sensing signals are correct as well.
