Rotation:

CW – B Leads A

CCW – A Leads B

Figure D.2: Differential Encoder Signal Timing

Note: Rotation is as viewed from the cover side.

(C)One Cycle: 360 electrical degrees (°e)

(X/Y)

Symmetry: A measure of the relationship between X and Y, nominally 180°e.

(Z)Quadrature: The phase lag or lead between channels A and B, nominally 90°e. (Po) Index Pulse Width: Nominally 90°e.
