Disconnect the motor from the controller and connect it in the test configuration shown
in Figure 1-3. Motor leads 1, 2, and 3 should be connected to the ends of the three
resistors wired in a Wye configuration. The Hall common lead coming from the motor
should be connected to the power supply common. The 5V Hall power lead should be
connected to the 5V power line. The three Hall signal wires should be connected through
the remaining three resistors to the 5V lead of the power supply.
Figure 1-3: Wye Resistor Test Setup Configuration
Motor voltage is monitored without power applied to the
motor. Before performing these steps, remove all
connections to the motor except the wye resistor network.
Remove all mechanical connections to the motor shaft.
