1. If not done so already turn off the power supply and connect the two brushed DC motors to the EVM screw
terminal blocks J13 and J14. Alternatively in single H Bridge mode connect a single motor to terminal J14.
First motor, Motor-1 pair of wires should be connected to J14 and the second motor, Motor-2 pair of wires
should be connected to J13. Turn on the lab power supply. Be sure to switch off the lab power supply when
swapping the motor connections. Note: If only one motor is available the tests can be conducted for one
motor at a time, first for the motor connected to J14 and next for the motor connected to J13.
2. Go to the “LOAD CONTROL” tab in the “Driver Control” page. The VM Voltage widget will read out the input
voltage to J12. Leave MODE1 and MODE2 settings in its default value. Set the “Motor Driver” to “Awake”.
