EtherCAT Communications
• Set the Servo Drives to stop operation if an error occurs in EtherCAT communications between the
Controller and a Servo Drive.
• Always use the specified EtherCA
T slave cables. If you use any other cable, the EtherCAT master
or the EtherCAT slaves may detect an error and one of the following may occur.
a) Continuous refreshing of process data communications will not be possible.
b) Continuous refreshing of process data communications will not end during the set cycle.
• Wiring slaves incorrectly in the ring topology to connect IN ports or OUT ports may cause message
and process data communication to stop. Make sure that the wiring of all slaves is correct.
• If synchronous slaves exist in the network configuration when a slave outside the ring topology is
disconnected or disconnected, the cable redundant is temporarily disabled due to the DC synchroni-
zation correction process.
USB Device
• Always use USB memory devices that comply with the USB standards.
