B-2 Connecting a Differential Encoder

4. Look at the A input signal and its complement A signal.

Whichever signal is low for at least part of the marker interval

should be wired to the A(+) terminal. If both signals meet this

condition, then either signal may be wired to the A(+) terminal.

Wire the remaining signal to the A(-) terminal.

5. Since the encoder may be mounted on either end of a motor

shaft, the encoder may spin clockwise or counter-clockwise for

a given shaft direction. As a result, the direction (phasing) of the

encoder may be backwards. If this is the case, exchange the

A(+) wire with the A(-) wire.
