Defi nitions
Count (N): The number of bar and window pairs or counts
per revolution (CPR) of the codewheel.
1 Shaft Rotation
Pulse Width (P): The number of electrical degrees that
an output is high during 1 cycle. This value is nominally
180°e or 1/2 cycle.
Pulse Width Error (ΔP): The deviation, in electrical degrees
of the pulse width from its ideal value of 180°e.
State Width (S): The number of electrical degrees between a
transition in the output of chan nel A and the neighboring
transition in the output of channel B. There are 4 states per
cycle, each nominally 90°e.

= 360 electrical degrees (°e),
= 1 bar and window pair.
Output Waveforms
State Width Error (∆S): The deviation, in electrical degrees,
of each state width from its ideal value of 90°e.
Phase (φ): The number of elec trical degrees between the
center of the high state of chan nel A and the center of
the high state of channel B. This value is nominally 90°e
for quadrature output.
Phase Error (∆φ): The deviation of the phase from its ideal
value of 90°e.
Direction of Rotation: When the codewheel rotates in the
direc tion of the arrow on top of the module, channel A will
lead channel B. If the codewheel rotates in the opposite
direction, channel B will lead channel A.
