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.
