4.1 Overview

The DRV10987 EVM is provided with a GUI to configure the device and tune the application. See

Appendix A for instructions to download and install the GUI application. The GUI is structured into three

tabs (Basic Settings, Advanced Settings, and Display) allowing configuration of the register settings and tuning of the device parameters for the target application. For details about the settings, refer to the

DRV10987 12- to 24-V, Three-Phase, Sensorless BLDC Motor Driver data sheet.

The following sections include DRV10987 GUI images to explain the various features of the GUI.

4.2 Basic Settings

The Basic Settings tab is the landing screen after launching the GUI on the computer. The tab sets the motor parameters, startup parameters, initial speed detection prior to startup, and current limits. This tab can also load and save motor parameters and program the EEPROM with optimized settings.
