NOTE
Otherwise components may be damaged: Note encoder supply voltage!
Note the limit values for the supply voltage specified in the data sheets of the encoder manufacturers. The
encoder supply voltage may have to be adjusted in object

LED
Color
Meaning
RUN (1)
green
This LED indicates the terminal's operating state:
off
State of the EtherCAT State Machine:
INIT
= initialization of the
terminal
flashing
State of the EtherCAT State Machine:
PREOP
= function for mailbox
communication and different standard-settings set
single flash
State of the EtherCAT State Machine:
SAFEOP
= verification of the
sync manager channels and the distributed clocks. Outputs remain
in safe state
on
State of the EtherCAT State Machine:
OP
= normal operating state;
mailbox and process data communication is possible
flickering
State of the EtherCAT State Machine:
BOOTSTRAP
= function for
terminal firmware updates
ENABLED 1 (2)
ENABLED 2 (4)
green
ON
Connected encoder for the corresponding channel initialized and
ready for operation
OFF
Connected encoder for the corresponding channel not ready for
operation
ERROR 1 (3)
ERROR 2 (5)
red
ON
No encoder connected to the corresponding channel, or position
values invalid (CRC error, not referenced, EnDat error bit set)
FLASHES
Error during initialization (see
)
OFF
No error
ENC SUPPLY
(9)
green
ON
Encoder voltage available
OFF
24 V field voltage missing or encoder voltage overload
RX 1 (10)
RX 2 (12)
green
FLASHES
Terminal receives position values at the corresponding channel
