EL5101-0011 - LEDs and Connection
Notice | |
Encoder supply via the terminal The encoder supply voltage, can be taken from the terminal points 1’(5 V) and 5`(0 V). |
Notice | |
Single-ended connection for TTL encoder For information on the single-ended connection for TTL encoders, please refer to chapter "Single-Ended Connection for TTL Encoders ("Normal Operating Mode" or "Enhanced Operating Mode").

LEDs
LED | Color | Meaning | |
|---|---|---|---|
INPUT A, B, C | green | indicates TRUE level | |
RUN | green | This LED indicates the terminal's operating state: | |
off | State of the EtherCAT State Machine: INIT = initialization of the terminal or BOOTSTRAP = function for firmware updates 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. | ||
on | State of the EtherCAT State Machine: OP = normal operating state; mailbox and process data communication is possible | ||
POWER 5 V | green | Operating voltage display for incremental encoder power supply | |
