Question

You ale offered a choice of an incremental shaft encoder or an absolute shaft encoder for the measurement of an angle displacement. What is the principal difference between the results that can be obtained by these methods?

Answer 1

Absolute shaft encoder gives a unique specific code to each shaft angle or position which can then identify the absolute position of the encoder.

Incremental shaft encoder produces an output signal every time the shaft rotates a certain angle. It can only measure the change in position.
