What is the difference between absolute and incremental measurement system?

Difference between absolute and incremental measurement system

The measuring system returns the absolute value of the current position is absolute

measurement.

Absolute position information is immediately available even after power loss.

The measuring system returns the relative value of the current position is incremental system.

Incremental System must always come back to a reference point.

This occur  when the machine initially starts and whenever something interrupts its power supply.
