2.3.1.4. Encoder Phasing
Incorrect encoder polarity will cause the system to fault when enabled or when a move command is
issued. Figure 2-17 illustrates the proper encoder phasing for clockwise motor rotation (or positive
forcer movement for linear motors). To verify, move the motor by hand in the CW (positive) direction
while observing the position of the encoder in the diagnostics display (see Figure 2-18 ).
For dual loop systems, the velocity feedback encoder is displayed in the diagnostic display ( Figure 2-
18 ).

IMPORTANT : Encoder manufacturers may refer to the encoder signals as A, B, and Z.
The proper phase relationship between signals is shown in Figure 2-17 .
