Selecting An Absolute Encoder; Handling Batteries - YASKAWA SGDH User Manual

8.4.2 Selecting an Absolute Encoder

An absolute encoder can also be used as an incremental encoder.

• The SEN signal and back-up battery are not required when using the absolute encoder as an incremental encoder.
• After changing these parameters, turn OFF the main circuit and control power supplies and then turn them ON again to
enable the new settings.

8.4.3 Handling Batteries

In order for the absolute encoder to retain position data when the power is turned OFF, the data must be backed
up by a battery.
• Install the battery at either the host controller or the SERVOPACK.
It is dangerous to install batteries at both simultaneously, because that sets up a loop circuit between the batteries.
