Description

1

A1

green, red

green: indicates TRUE level

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

  • The corresponding input is differentially wired, Corresponds to:
    "Counter mode" 0x8001:1D =0 (Encoder RS422 (diff. input))
    or
    "Counter mode" 0x8001:1D =1 (Counter RS422 (diff. input))
  • The "Error Detection" of 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).

Status Input

red

Fault signal input from rotary encoder. Input is internally connected to 5 V via a pull-up resistance. 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

Power Enc.

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

8

Digital output 1

green

is lit, if output 1 is set (+24 VDC)

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 terminal firmware updates

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

16

Digital output 2

green

is lit if output 2 is set (+24 VDC)
