    If this your first encounter with the DRV10963, before proceeding to next step, install the following software packages to use the DRV10963 GUI for tuning the motor: 1. The DRV10963 EVM is provided with a GUI to configure the device and tune the application. Refer to DRV10963_2P0 User Manual.pdf present (C:\Program Files (x86)\Texas Instruments\DRV10963_2P0 EVM\Documents) in the GUI-installed directory for instructions to download and install the GUI application.

    Each one of the parameters that you can configure with the GUI will change how your motor reacts to the DRV10963 device. Read the description of each one of the parameters below and then choose if you would like to make the changes suggested. Be sure to connect a current probe to phase V to observe the phase current during tuning.
