LEDs 1:
EJ5112 - LEDs

Single-Channel mode 1 x ABC

No.

Name

Color

Description

A

Run

green

This LED indicates the module´s operating state:

off

State of the EtherCAT State Machine: INIT = initialization of the module or BOOTSTRAP = function for firmware updates of the module

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 are possible

B

Diag

red

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

C

ENC

green

Operating voltage display for incremental encoder power supply

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 VID Low is typically less than 0.67 V (subject to change).

DI neg

green

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

6

Latch

green

is on, if a signal (+24 V) is presented to the latch input

7

Gate

green

is on if a signal (+24 V) is presented at the gate/latch input
