As the codewheel rotates an
alternating pattern of light and
dark corresponding to the pattern
of the codewheel falls upon the
photodiodes. This light is used to
produce internal signals A and
A, and B and B. As part of this
“push-pull” detector system, these
signals are fed through
comparators that are part of the
signal processing circuitry to
produce the final outputs for
channels A and B.
Definitions
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.
Cycle Error (
C):
An indication
of cycle uniformity. The
difference between an observed
shaft angle which gives rise to
one electrical cycle and the
nominal angular increment of 1/N
of a revolution.
One Shaft Rotation:
360
mechanical degrees, N cycles.
Position Error (
Θ
):
The
normalized angular difference
between the actual shaft position
and the position indicated by the
encoder cycle count.
Pulse Width (P):
The number of
electrical degrees that an output
is high during one cycle,
nominally 180
°
e or
1
/
2
a cycle.
Pulse Width Error (
P):
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
channel A and the neighboring
transition in the output of
channel B. There are 4 states per
cycle, each nominally 90
°
e.
State Width Error (
S):
The
deviation in electrical degrees of
each state width from its ideal
value of 90
°
e.
Phase ():
The number of
electrical degrees between the
center of the high state on
channel A and the center of the
high state on channel B. This
value is nominally 90
°
e for
quadrature output.
Phase Error (
):
The deviation
in electrical degrees of the phase
from its ideal value of 90
°
e.
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.
