LED Color Meaning
RUN green This LED indicates the terminal's operating state:
off State of the EtherCAT State Machine: INIT=initialization of the terminal
flashing
rapidly
State of the EtherCAT State Machine: BOOTSTRAP=function for terminal firmware up-
dates [}244]
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 chan-
nels 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
Drive OK green on Driver stage ready for operation
