Incremental Encoder
Everest XCR can use single-ended or differential digital incremental encoder inputs (also known as quadrature
incremental encoders) for velocity and/or position control, as well as for commutation purposes. The encoder
provides incremental position feedback that can be extrapolated into precise velocity or position information.
Using high resolution encoders allows Everest XCR to perform sinusoidal commutation. Channel A and channel B
signals should have a phase shift of 90 degrees, indicating the rotation direction. The drive has an optional index
signal input. Index signal (Z) is a single pulse per revolution signal that can be used to know absolute positions and
for homing operations
. The following table illustrates the
digital
encoder inputs main features.
