Advantages of Absolute！

Non-volatile Memory

An absolute encoder functions as a non volatile position verification device. True
position is not lost if the power fails or the system moves while power is off. A
continuous reading of position is not required. This is particularly useful in applications, such as satellite tracking antennas, where occasional position
verification is all that's necessary

Programming Flexibility.By eliminating the need for system homing, absolute encoders can be controlled to provide positioning programs based on establishing reference from point-to-point, rather than from a home position.In addition, a microprocessor interface module enables the system designer to program in several operating parameters,including resolution.

Safety
In some applications, a loss of position could result in damage to the machinery
or injury to the operator. An absolute encoder provides position verification
the moment power is up.
