4.6. Precaution for absolute encoder
In the host controller, when detecting the absolute position of the machine even when the power
of the servo drive is turned off, you must use an absolute type servo motor and drive. If you
connect the power to the absolute type servo system, you can make a machine system that can
directly enable auto operation with additional position detection operation without the difference
between the absolute type drive and standard type drive is whether there is a back-up battery.
4.6.1. Battery handling
The battery supplies the back-up power to store the position information of the “Absolute
encoder” even when the drive power is turned off.
