Theory of Operation
The AEDS-96EX is a C-shaped emitter/detector module.
Coupled with a codewheel/codestrip, it translates
rotary motion into a two-channel analog output.
The module contains a single Light Emitting Diode
(LED) as its light source. The light is collimated into a
parallel beam by means of a single lens located directly
over the LED. Opposite the emitter is the integrated
detector circuit. This IC consists of multiple sets of
photodetectors and the signal processing circuitry
necessary to produce the analog waveforms.
The codewheel/codestrip moves between the emitter
and detector, causing the light beam to be interrupted
by the pattern of spaces and bars on the codewheel/
codestrip.
The photodiodes, which detect these interruptions, are
arranged in a pattern that corresponds to the radius
and count density of the codewheel/codestrip.
These detectors are also spaced such that a light period
on one pair of detectors corresponds to a dark period
on the adjacent pairs of detectors. The photodiode
outputs are fed through the signal processing circuitry,
which produce the final outputs for Channel A and
Channel B. Due to this integrated phasing technique,
the analog output of Channel A is in quadrature with
Channel B (90 degrees out of phase).
Definitions
Count (N)
: The number of bar and window pairs or
counts per revolution (CPR) of the codewheel. Or the
number of lines per inch of the codestrip (LPI)
1 shaft Rotation = 360 degrees = N cycles
1 cycle (c) = 360 electrical degree, equivalent to 1
bar and window pair.
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.
Line Density
: The number of window and bar pair per
unit length, express in either lines per inch (LPI) or lines
per mm (LPmm)
Optical Radius (Rop)
: The distance from the
codewheel’s center of rotation to the optical center
(O.C) of the encoder module.
Gap (G)
: The distance from surface of the encoder to
the surface of codewheel or codestrip
Mounting Position (RM)
: Distance from Motor Shaft
center of rotation to center of Alignment Tab receiving
hole.
Radial and Tangential Misalignment Error (ER and
Er)
: For rotary motion mechanical displacement in the
radial and tangential directions relative to the nominal
alignment
Angular Misalignment Error (EA)
: Angular
misalignment of the sensor in relation to then
tangential direction. This applies for both rotary and
linear motion.of electrical degrees that an output is
high during one cycle, nominally 180°e or 1/2 a cycle.
