Battery refreshment of the absolute encoder with battery
If batteries (lithium-thionyl chloride battery) are not discharged for a long time, including long storage,
battery alarm may occur due to the phenomenon of transient voltage drop at the next discharge. In order
to prevent this, you can perform battery discharge treatment (refreshment).
Battery refreshment is performed by PANATERM for Multi(USB communication, EoE communication).

When battery refreshment is executed, battery warning may occur. In that case, clear the
battery warning.

Do not refresh the battery with a batteryless absolute encoder.
4.7.2 External scale
Under full-closed control, an absolute system that does not require return to origin action after power-up,
can be configured.
External scale absolute system configuration

Absolute system configuration using EtherCAT communication interface
(Example: with driver module 2-axes connection)
In the EtherCAT communication response (driver to host controller), the absolute data is transferred to
the host controller as the current position data.
