Absolute Encoders

The absolute encoder records the current position of the stop position even when the power supply is
OFF.
With a system that uses an absolute encoder, the host controller can monitor the current position.
Therefore, it is not necessary to perform an origin return operation when the power supply to the sys-
tem is turned ON.
There are four types of encoders for Rotary Servomotors. The usage of the encoder is specified in
Pn002 =
SERVOPACKs with software version 0023 or higher support batteryless absolute encoders.
Refer to the following section for encoder models.


Install a battery at either the host controller or on the Encoder Cable.
If you install batteries both at the host controller and on the Encoder Cable at the same time, you
will create a loop circuit between the batteries, resulting in a risk of damage or burning.
