DRV8320: DRV8320H Motor Hums but does not spin.

Part Number: DRV8320

Hi,

I'm having problems with DRV8320H.   Motor hums but does not spin. 

I am running with following settings..

* Supply Voltage 12.5V@24A.

* 1x PWM with MODE pin floating.

* PWM /  I/O controlling from Arduino.

* IDRIVE and VDS are pulled up to DVDD with 18K resistor.

* Motor resistance between each phase is 0.3 Ohm.

* Motor configured as Delta Winding. 

Thanks,

    Hector,

    I am able to spin motor at low speed 20ms delay in between the states @25 PWM (0-255)

    Thanks...

    Hector,

    I am able to spin motor at low speed, 20ms delay in between states.

    Thanks...

    Hi Raj,

    This e2e slipped. Have you resolved the issue of spinning the motor at your desired speed?

    What do you mean by parallel control, exactly? Thank you.

    No luck, I am behind on the schedule. The DRV8320 specs does not show exact timing i need to apply to drive in 1X PWM mode or i may have overlooked.

    Problem still exists and cannot be solved from my side...
    Do not close this thread..
    Thanks

    Hi Raj,

    When you say the timing you need, do you mean the PWM is 3.921 kHz? Or is it any other timing parameter
