Quadrature Encoder Interface
(QEI) Module
Quadrature encoders (also referred to as incremental
encoders or optical encoders) are used in position and

of
rotating
motion
Quadrature encoders enable closed-loop control of
many motor control applications, such as Switched
Reluctance (SR) Motor and AC Induction Motor
(ACIM).
Typically, three outputs termed, Phase A, Phase B and
INDEX, provide information that can be decoded to
provide information on the movement of the motor
shaft, including distance and direction.
A quadrature decoder captures the phase signals and
index pulse and converts the information into a numeric
count of the position pulses. Generally, the count will
