Board Settings

In sensorless vector control, the motor position is inferred from the current flowing in each phase.
The phase currents can be sensed by connecting both ends of the shunt resistors (SR1, SR2, and SR3) of
each phase to the built-in differential amplifiers of the RAA306012 or the external current sense circuit. In the
sample program, the built-in differential amplifiers are disabled, and the external current sense circuit is used
for the phase current sensing.
Align the board connection settings on the Evaluation Board with Figure 3-3.
For details on the circuit diagram of the Evaluation Board, refer to the Schematic (R12TU0221EJ).
Note.1: This setting is factory default setting. The sensorless vector control can be evaluated without changing the board connection
setting from factory default setting.
