Precautions for Safe Use
• If the node address is not set correctly, invalid device parameters may be set in the wrong
EtherCAT Slave Unit, so check the connected Unit before downloading parameters.
• The EtherCAT Slave Unit must restart in order to enable the parameter settings that are
transferred to it. Verify that restarting the Unit will not cause any problems in the system
before restarting it.
If the synchronization operation of the Sysmac Studio is used for downloading, the EtherCAT
Slave Unit restarts automatically.
