3.4.1 Free Run
The controller runs under non-synchronization with Master. Under Free Run mode, Master
and Controller have an individual independent cycle.
3.4.2 SM Event
The controller runs under synchronization with SM event of EtherCAT communication. SM
event is generated once the controller receives EtherCAT frame.
Once synchronization by SM event, each one of the controllers has a little bit of jitter.
3.4.3 DC Sync Event
The synchronized controller runs under sync Interrupt which is generated according to
distributed Clock (following DC).
DC is synchronized time shared between Master and Slave. With a synchronized clock,
interrupt is generated under accurate synchronization and the controller executes
commands under accurate timing. In this case, each controller has a little bit of jitter.

EtherCAT Slave Information
EtherCAT slave Information file (XML File) is needed to connect the controller with EtherCAT
master. This file is described slave device information as XML format based on EtherCAT
specifications. Recording the XML file into EtherCAT master equipment through EtherCAT
setting equipment, easily implement PDO and SDO setting to a Slave device.
Information
The XML file can be downloaded from the product website.
