DRV8323: Torque and Voice Problem

Part Number: DRV8323

Hi,

I am using DRV823S my project(Motor Control). I have a problem.I have tried trapezoidal and sinuzoidal BLDC control.

Trapezoidal Control: No problem working at no load but it makes a lot of clicks while on load operation(PWM frequency: 16khz).

Sinuzoidal Control: I'm having a torque problem. Also, there is a lot of voice in some pwm values(PWM frequency: 16khz).

Can you help with this issue?
