7 GUI Operations DRV8962EVM and DRV8962VEVM

  1. Depending on low side or high side low configuration use Jumpers J13 and J14 to connect the motors to the half bridges and J23 for VM and GND

  2. For example, using low side low configuration: go to the “LOAD CONTROL” tab in the “Driver Control” page. The VM Voltage widget will read out the input voltage to J12. Set the “Motor Driver” to “Awake”. Using the drop-down menu displaying “Hi-Z” choose “Low Side Load” for HB1, HB2, HB3 and HB4.

  3. Press all the four “Start Drive 1,2,3 and 4” buttons. The HB1, HB2, HB3 and HB4 PWM INPUTS sliders will turn active now. PWM duty cycle input for each of the half bridges HB1 to HB4 can be set using IN1 Duty Cycle (%) to IN4 Duty Cycle (%) widgets respectively. The corresponding output currents calculated from respective IPROPI outputs will be displayed in the "Output Status" panel. Switch the “Motor Driver” widget to “Asleep”. The motors will spin down to a stop.

  4. The panel on the right will display the Output Status of each half-bridge, clear faults, set the PWM frequency, set the OCPM mode, output rise/fall time, and VREF for current regulation. Be sure to make any changes when the Motor Driver is "Asleep".
