3 EV Board Operation

3.1 Connect the Motor Connector and the Hall Sensor Connector

Before power on, connect the motor lines to the motor connector and the hall sensor

connector according to the following direction. Refer to Figure 3-1.

Note: If the driving method is Back EMF, the hall sensor connector should not be connected.

Figure 3-1: Connect Motor Connector and Hall Sensor Connector

3.2 Select the Driving Method as Hall Sensor or Back EMF

If you want to select the hall sensor, the switchers are set as J1(2-3),J2(2-3), and J3(2-3).

Otherwise, the switchers are set as J1(1-3),J2(1-3), and J3(1-3). Switch on the power and

the power LED turns

on.

you want to change the FW driving method, press the hall sensor/B-EMF key when the

motor is stopped. Then, the LED3 turns off. It means the FW driving method is hall sensor.

Refer to Figure 3-2.

Notes: the selection of the FW driving method should match with the selection of switchers.
