DRV10975: I can not control speed on speed pin

Mitja Nastran

Part Number: DRV10975

Hello, why I can not change speed of motor with speed pin. I have tried using PWM and potentiometer. With PWM no mather what it is always 100%. With potentiometer it will not even turn on until when it is half turned, then it will spin 100%.

Hello Mitja,

Thanks for posting to the MD forum. I will close this thread as you mentioned in another post that the lack of speed control was due to the AVS function being enabled: https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1074478/drv10975-my-driver-doesn-t-work-properly
