2.9 Connecting the EtherCAT
Dual RJ-45 connectors (connection CN3) 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.
2.9.1 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).

• Blinking: Flashing with equal on and off periods of 200ms (2.5Hz)
• Single Flash: Repeating on for 200ms and off for 1s
• Double Flash: Two flashes with a period of 200ms followed by off for 1s
