detectors corresponds to a dark
period on the adjacent pair of
detectors. The photodiode
outputs are fed through the signal
processing circuitry. Two
comparators receive these signals
and produce the final outputs for
channels A and B. Due to this
integrated phasing technique, the
output of channel A is in
quadrature with channel B (90
degrees out of phase).
Definitions
Note: Refer to Figure 2.
Count (N) = The number of bar
and window pairs or counts per
revolution (CPR) of the
codewheel.
One Cycle (C)
= 360 electrical degrees (e)
= 1 bar and window pair
One Shaft Rotation
= 360 mechanical degrees
= N cycles
each state width from its
ideal value of 90
°e.
Pulse Width (P): The number of
electrical degrees that an output
is high during one cycle. This
value is nominally 180e or 1/2
cycle.
Pulse Width Error (
P): The
deviation, in electrical degrees, of
the pulse width from its ideal
value of 180e.
State Width (S): The number of
electrical degrees between a
transition in the output of
channel A and the neighboring
transition in the output of
channel B. There are 4 states per
cycle, each nominally 90e.
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
electrical degrees between the
center of the high state of
channel A and the center of the
high state of channel B.
Phase Error (
φ): The deviation
of the phase from its ideal value
of 90e.
Direction of Rotation: When
the codewheel rotates in the
counterclockwise 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.
Optical Radius (ROP): The
distance from the codewheel’s
center of rotation to the optical
center (O.C.) of the encoder
module.
Angular Misalignment Error
(EA): Angular misalignment of
the sensor in relation to the
tangential direction. This applies
for both rotary and linear motion.
Mounting Position (RM): The
distance from motor shaft center
of rotation to center of alignment
tab receiving hole.
