5.2 DRV8328AEVM GUI Quick Start Guide

  1. Enter the PWM frequency in Hz using the “PWM Frequency (Hz)” text box. Press Enter.

  2. Adjust the MCU dead time and Acceleration Delay values. For DRV8328A/B, it is recommended to use the DT potentiometer and set MCU dead time to 0 ns.

  3. Click on the “Output Enable” switch.

  4. To control the motor speed using the potentiometer R91, turn the potentiometer all the way counterclockwise to set to 0% speed. Click on the “Potentiometer Enable” switch to use the potentiometer to control the speed of the motor. If you do not wish to use the potentiometer, skip this step.

  5. Turn the potentiometer clockwise or adjust the “Duty Cycle” slider to control the speed of the motor from 0% to 100%.

  6. Use the “Direction” switch to switch the direction of the motor.

  7. Use the drop-down menu in “Motor Braking” to determine the motor braking type. Click on “Stop Motor” to stop the method with the selected braking type.
