Connection, display and diagnostics
LED | Color | Meaning | |
---|---|---|---|
RUN | green | These LEDs indicate 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 default settings set | ||
single flash | State of the EtherCAT State Machine: SAFEOP = verification of the Sync Manager channels and the distributed clocks. | ||
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 Firmware updates of the terminal | ||
ERROR | red | - Error ADC | |
ERROR | red | - Error DAC |
Notice | |
Maximum current load of the power contacts and connection points
|
Notice | |
Cable lengths >30 m For longer cable lengths >30 m, suitable overvoltage protection must be provided (e.g. EL9540-0010) if corresponding interference could affect the signal cable. |
