Single Brushed DC Motor Control with Paralel H-bridge Mode
Note: The DRV8412 Mode jumpers must be modified from their default setting for this mode. With
power removed set M1 to L, M2 to H and M3 to L.
1) User can choose a voltage or current control mode. Mode is chosen by selecting either the Voltage
Mode or Current mode tab. There is a knob to set the value and a gauge showing the setpoint. The
setpoint has a slew rate limit so there will be a delay between the knob setting and the gauge display.
The graph window to the right shows the current feedback for the motor.
2) There is a settings tab to modify the DC Bus range and provide current loop tuning. The parameters
have been tuned for light loads and a 24V DC bus with a +/-20% tolerance.

Shutting Down
1) Once finished evaluating, uncheck the Enable Motor check box to stop the motor. Once the motor
comes to a full stop the GUI can be closed. Now unplug the 24V DC power supply. As the capacitors
are charged the PVDD LED may remain ON for a couple of seconds. Do not touch the board unless this
LED goes OFF.
2) All future updates/enhancements to the GUI and/or Flash image would be made available through
controlSUITE.
3) Please note that the Flash image is meant for quick demonstration purpose only. For a more detailed
explanation and understanding on the control algorithm being used and tradeoffs, refer to the individual
project for the motor type and control method being implemented under
controlSUITE\developement_kits\DRV8412-EVM.

Information about the board settings and connections can be found on the Board Layout tab within the GUI.
