Switch Setting
The value of the ID switches of the slave is used as the node address.
(1) Set the ID switches during power OFF.
(2) When the slave power is turned ON, the value of the ID switches is applied to the register:
0012 hex.
(3) The EtherCAT master reads the value that is set in Register: 0012 hex.
(4) The EtherCAT master writes the value of 0012 hex to 0010 hex as the node address.
The serial number saved in the non-volatile memory of the Servo Drive is displayed in the Serial Num-
ber (1018-04 hex). Controllers that support Sysmac Device Features can use this serial number to
check the network configuration.
To enable this check, in Sysmac Studio, set Serial Number Check Method to Setting = Actual
Device on the EtherCAT tab page.
If the specified condition is not met, a Network Configuration Verification Error will occur.
This network configuration check can detect the replacement of slave devices, which prevents
you from forgetting to set parameters on those slaves.
The ESI Specification is a set of specifications that define the entries required in an EtherCAT Slave
Information (ESI) file.
Controllers that support Sysmac Device Features can use the Option function defined in the ESI Speci-
fication to identify the backup parameters stored on slaves.
The backup parameters on an identified slave can be backed up and restored from Sysmac Studio.
