Chapter 5 Memory and Parameter
5-23
1) Slave Name
It selects the slave to be connected to the motion control module and displays the name of the selected slave. L7NH servo
drive is selected as the initial value when adding the slave to the slave data.
When selecting the slave, the slave information is retrieved from the XML file in the folder below to display the available list.
\EtherCATXML folder in XG5000 installation folder’
If there is a slave to be newly added, copy the corresponding XML file to the above folder and then, restart XG5000 or
execute the 'ESI Rescan' menu which is activated by right-clicking in the 'ESI Library' window.
2) Station number
It displays the station number applied to the selected slave. The display range is from 1 to 64 and it cannot be arbitrarily
changed by a user. To change the slave station number, select the slave in the project tree and among menus by right-
clicking, execute the 'Properties' menu and then, change the station number on the slave information.
However, the station number is automatically set according to the order of connection when the slave is connected
automatically.
3) Vendor
The vendor name of the selected slave is automatically displayed. The user cannot change it arbitrarily.
4) Version
The Revision information of the selected slave is displayed automatically. The user cannot change it arbitrarily.
5) Serial number
The serial number of the selected slave is displayed. When "Read Serial Number" is executed during EtherCAT
communication, serial number of the current product is displayed.
6) Whether DC is used
If the slave supports the DC function, it is automatically set form the XML file. If you do not want to use the DC function,
select ‘0: Unused’.
DC(Distributed Clock): It is used to synchronize the EtherCAT master with the EtherCAT slave, enabling high-precision
synchronous control between the EtherCAT slaves.
The DC shares the time information between the EtherCAT master and EtherCAT slave to synchronize each slave. In order
to share the time information, the first slave connected to the motion control module provides the Reference Clock. The
Reference Clock distributes the time information to each slave in every communication cycle.
7) Replacement function during connection
If the slave which has been stopped due to network disconnection or abnormal operation using the cable redundancy
function is recovered from the error and connected to the network, it will detect the connection. Then, it provides the
connection with the network of the individual slave without reconnection of the whole network.
For more details on the function, refer to 8.3.6 ‘Replacement during connection’.
