Direction of Rotation: When the
codewheel rotates in the counter-
clockwise direction (as viewed
from the encoder end of the
motor), channel A will lead

channel B. If the codewheel
rotates in the clockwise direction,
channel B will lead channel A.
Index Pulse Width (PO): The
number of electrical degrees that
an index output is high during
one full shaft rotation. This value
is nominally 90°e or 1/4 cycle.
