8.7 Absolute Encoders
If a motor with an absolute encoder is used, a system to detect the absolute position can be made in the host
controller. Consequently, operation can be performed without zero point return operation immediately after
the power is turned ON.
8.7.1 Encoder Resolution
The encoder resolution is shown below.
The absolute encoder can be used as an incremental encoder by setting the Pn002.
A battery is not required when using the absolute encoder as an incremental encoder.
8.7.2 Backup of the Settings
A battery is required to save position data in the absolute encoder.
Install a battery to the power regeneration converter.
For the battery, refer to
2.3.3 Absolute Encoder Battery.
