NOTE 1: Encoder output voltage should be at or near the encoder power supply voltage.
8 . Turn the motor shaft by hand. As Figure 6-1 shows, there should be pulses on both
channels, 50% duty cycle, and they should be the inverse of each other (separated by
180 electrical degrees.
9 . If one or both channels do not have the correct pulses present (i.e. missing pulses,
incorrect duty cycle, improper voltage, etc.), go to procedure C.
