Defi nitions
Count (N):
per revolution (CPR) of the codewheel.
One Cycle (C):
pair.
One Shaft Rotation:
Position Error (ΔΘ):
between the actual shaft position and the position
indicated by the encoder cycle count.
Cycle Error (ΔC):
ference between an observed shaft angle which gives rise
to one electrical cycle, and the nominal angular increment
of l/N of a revolution .
Pulse Width (P):
output is high during 1 cycle. This value is nominally 180°e
or 1/2 cycle.
Pulse Width Error (ΔP):
of the pulse width from its ideal value of 180°e.
State Width (S):
a transition in the output of channel A and the neighbor-
ing transition in the output of channel B. There are 4 states
per cycle, each nominally 90°e.

State Width Error (ΔS):
of each state width from its ideal value of 90°e.
Phase (φ):
center of the high state of channel A and the center of the
high state of channel B. This value is nominally 90°e for
quadrature output.
Phase Error (Δφ):
value of 90°e.
Direction of Rotation:
direction of the arrow on top of the module, channel A will
load channel B. If the codewheel rotates in the opposite
direction, channel B will lead channel A.
Optical Radius (R
center of rotation to the optical center (O.C.) of the
encoder module.
Index Pulse Width (P
that an index is high during one full shaft rotation. This
value is nominally 90°e or 1/4 cycle.
