Absolute Encoder
Provided for absolute indirect position detection within 65536 motor
revolutions. Replaces separate absolute value encoders at the motor.
Note: The absolute axis position at this encoder variety still exists
because of the battery back-up also after power shut down.
If you disconnect the motor from the drive controller, you will
lose the absolute axis position after approx. 1 minute.
