The difference between absolute encoder and incremental encoder！
Changchun Rongde Optics Co.,Ltd. Release time：2016/10/10 Browse：825The difference between incremental and absolute encoders is analogous to the
difference between a stop watch and a clock.
A stop watch measures the incremental time that elapses between its start and
stop, much as an incremental encoder will provide a known number of pulses。relative to an amount of movement. If you knew the actual time when you started the watch, you can tell what time it is later by adding the elapsed time value
from the stop watch. For position control, adding incremental pulses encoder to a known starting position sensor will measure the current position.
When an absolute encoder is used, the actual position will constantly be transmitted, just as a clock will tell you the current time.
