5.3 BLDC Motor Outputs and Feedback
5.3.1 Introduction
The Motor Control board can be configured to drive a BLDC motor in
Sensor/Sensorless mode, Open/Closed Loop mode, and an AC motor in
Open/Closed loop. This sections explains how to configure the Motor Control
board to drive a BLDC motor, while the next section explains how to
configure the Motor Control board to drive an AC motor. The following figure
illustrates where the input (sensor) connectors, the output connector (motor
phases) and related jumper settings selectors are located.
