DRV8434EVM: Query Regarding Minimum Start Speed (50 PPS) on DRV8434EVM GUI

Part Number: DRV8434EVM

Hi Team,

Posting on behalf of our customer.

I am using the DRV8434EVM board for testing. Using the GUI, I can drive the motor successfully.

However, when using the EVM GUI, the motor only starts from a minimum speed of 200 PPS. I would like to know how I can configure or modify the GUI or firmware to allow the motor to start at 50 PPS instead of 200 PPS.

Could you please guide me on how to adjust this parameter or if there is any register or firmware setting related to the minimum start speed?

Regards,

Danilo

    The motor speed can be controlled by GUI through setting the Starting speed, Stopping Speed, Target speed and acceleration rate. Please check the screenshot below from user guide,.
