5.6 Absolute Encoders
If a motor with an absolute encoder is used, the absolute position is detected in the Sigma II
Indexer. Consequently, automatic operation can be performed without a homing operation
immediately after the power is turned ON.

5.6.1 Interface Circuit
The following diagram shows the standard connections for an absolute encoder
mounted to a servomotor.

5.6.2 Configuring an Absolute Encoder
Select the absolute encoder’s application with the following parameter.
Either “0” or “1” in the following table must be set in order to enable the absolute
encoder.
