EL5112 - LEDs

1

A1

green, red

Green: indicates TRUE level

Red: There is a broken wire at the respective input. Diagnosis is only possible if the following three conditions are met.

• The corresponding input is differentially wired, i.e.:
  „Counter mode“ 0x8001:1D =0 (Encoder RS422 (diff. Input))
  or
  „Counter mode“ 0x8001:1D =1 (Counter RS422 (diff. Input))
• "Error Detection" for the respective input is enabled:
  „Error Detection A“ 0x8000:0B = TRUE
  „Error Detection B“ 0x8000:0C = TRUE
  „Error Detection C“ 0x8000:0D = TRUE
• The differential voltage V_{ID Low} is typically less than 0.67 V (subject to change).

Status Input

red

Fault signal input from encoder. Input is internally connected to 5 V via a pull-up resistor. The encoder output must actively pull the signal against GND.

on

Output active at the encoder, a fault message is present at the encoder

off

Output not active at the encoder; no fault message is present

5

PowerEnc.

green

Operating voltage display for incremental encoder power supply

7

Latch

green

is lit, if a signal (+24 V) is connected to the latch input

9

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 default 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

10

Diag

red

Initialization process active or state of the EtherCAT State Machine: BOOT

15

Gate/Latch

green

is lit if a signal (+24 V) is present at the gate/latch input
