2.6 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.
2.6.1 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).
L/A OUT
ERR
L/A IN
RUN
LED Color Status Description
Link/Activity Green
OFF no Ethernet connection
ON Ethernet is connected
Flickering activity on line
RUN Green
OFF initialization state
Blinking pre-operational state
Single Flash safe-operational state
ON operational state
ERR Red
OFF no error
Blinking general error
Single Flash sync error
Double Flash watch dog error
Notes:
• Flickering: Rapid flashing with a period of approximately 50ms (10Hz)
• 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
2.7 Setting the EtherCAT Node ID
When the drive’s ID is configured to be assigned by master controller in Stepper Suite
software, the master controller can set the EtherCAT node Alias ID to address 0004h of SII (Slave
Information Interface) EEPROM. The drive can get this ID value from SII EEPROM address 0004h
after power up.
