BOOSTXL-DRV8323RS: For 280025C Launchpad, the speed set by me, namely 'speedref', is too different from the estimated speed value

Hi Team,

I used my PM motor driver. The parameters are known, and the boards are 280025C Launchpad and BOOSTXL-DRV8323RS. The voltage of the power supply is 24V.

I ran it under the condition of 'BuildLevel = 3, MOTOR1_FAST defined', and I set the speed to 50HZ. The estimated speed value in the observation window was very small, but by observing the phase current through the oscilloscope, I found that the actual speed value was the same as the speed set by me, which is 50HZ.

Could you please tell me what might have resulted in the wrong estimated speed value?

Kind regards,

Katherine
