Pulse Width (P): The number of electrical degrees that
an output is high during one cycle. This value is nomi-
nally 180°e or 1/2 cycle.
Pulse Width Error ('P): The deviation, in electrical de-
grees, of the pulse width from its ideal value of 180°e.
State Width (S): The number of electrical degrees be-
tween 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 de-
grees, of each state width from its ideal value of 90°e.
Phase (I): 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 ('I): The deviation of the phase from its
ideal value of 90°e.
Direction of Rotation: When the codewheel rotates
counterclock wise, as viewed looking down on the mod-
ule (so the marking is visible), channel A will lead chan-
nel B. If the codewheel rotates in the opposite 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.
