4.1.1 Loading Recommended Default Values

Select the Quick Spin option on the Motor Studio Home page or on the menu on the left side of the window. Using the Select Preset drop down menu in the Load Default section select a register configuration which is most similar to the application use case or the Default MCF8329A Registers option. After selecting the desired register configuration, click on the Load Preset Values button.
