Absolute Encoder Coding

An absolute encoder generates digital words that represent the encoder’s actual
position, as well as its speed and direction of motion. If power is lost, its output will
be correct whenever power is restored. It is not necessary to move to a reference
position as with incremental type encoders. Electrical transients can only produce
transient data errors, usually too brief to effect the dynamics of a control system.An absolute encoder’s resolution is defined as the number of bits in its output word.
This output can be in straight binary or in gray code, which produces only a single-
bit change at each step to reduce errors.
