5 EtherCAT Communications
5 - 16
G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
When the node address switch setting is “00” (Software Setup mode), the node address value you
set in Sysmac Studio is enabled.
In the Software Setup mode, in Sysmac Studio, execute [Write Slave Node Address] on the
[EtherCAT Edit] screen to save the slave node address setting in the nonvolatile memory of the G5-
series Servo Drive.
z
Software Setting
The set value saved as Slave Information Interface (SII) information in the nonvolatile memory of the
slave is the node address.
z
Node Address Switch Setting
The value set on the node address switches is the node address.

(1) The Node Address Switch is set to “00” at
power OFF.
(2) Write a node address set value to Slave SII
from the master.
(3) The value of the node address setting is
applied to Register: 0012 hex by the
software, when the slave power is ON.
(4) EtherCAT master reads the set value of
Register: 0012 hex.
(5) EtherCAT master writes the value of 0012
hex address to 0010 hex address as the
node address value.
