2.7 Connecting the EtherCAT
Dual RJ-45 connectors accept standard Ethernet cables and are categorized as 100BASE-TX(100
Mb/sec) ports. CAT5 or CAT5e (or higher) cables should be used. The IN port connects to a
master, or to the OUT port of an upstream node. The OUT port connects to a downstream node.
If the drive is the last node on a network, only the IN port is used. No terminator is required on the
OUT port.
2.7.1 EtherCAT Status Indicator LEDs
The LEDs are used for indicating status of the EtherCAT. There are two Link/Activity LEDs (one for
each RJ-45 Ethernet connector) and two status LEDs (RUN and ERR).
