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 (
φ
):
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.
Phase Error (
φ
):
The deviation
in electrical degrees of the phase
from its ideal value of 90
°
e.
Direction of Rotation:
When
the codewheel or codestrip moves
in the direction from pin 1 to pin
4, as viewed when looking down
on the lenses, channel B will lead
channel A. If the codewheel or
codestrip moves in the opposite
direction, channel A will lead
channel B.
Optical Radius (Rop):
For
rotary motion, the distance from
the codewheel’s center of rotation
to the center line connecting the
two lenses of the encoder.
Gap (G):
The distance from the
top of the package to the surface
of the reflective codewheel or
codestrip.
Specular Reflectance (R
f
):
a
measure of a surface’s reflective
finish. This is quantified by the
amount of light reflected when hit
with an incident beam. A device
called a scatterometer is used to
quantify specular reflectance on a
percent scale. (Contact factory for
more information.)
Radial and Tangential
Misalignment Error (E
R
, E
T
):
For rotary motion, mechanical
misalignment in the radial and
tangential directions relative to
the codewheel.
Angular Misalignment Error
(E
A
):
angular misalignment of the
sensor in relation to the tangential
direction. This applies for both
rotary and linear motion.
