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 (LPI) of the
codestrip.
1 Shaft Rotation = 360 mechanical
degrees
= N cycles
1 Cycle (c) = 360 electrical
degrees (
°
e)
= 1 bar and window pair
Pulse Width (P):
The number of
electrical degrees that an output
is high during one cycle. This
value is nominally 180
°
e or 1/2
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 four 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 of channel
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 counter-
clockwise, as viewed looking
down on the module (so the
marking is visible), channel A will
lead channel B. If the codewheel
rotates in the opposite direction,
channel B will lead channel A.
Optical Radius (R
OP
):
The
distance from the codewheel’s
center of rotation to the optical
center (OC) of the encoder
module.
Angular Misalignment Error
(E
A
):
Angular misalignment of
the sensor in relation to the
tangential direction. This applies
for both rotary and linear motion.
Mounting Position (R
M
):
Distance from motor shaft center
of rotation to center of alignment
tab receiving hole.
