LEDs

Left Prism

LED Color Meaning

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

blinking

State of the EtherCAT State Machine: PREOP = Setting for mailbox communication and variant standard settings

single flash

State of the EtherCAT State Machine: SAFEOP = Channel checking of the Sync Manager and the Distributed Clocks. Outputs stay in safe operation mode.

on

State of the EtherCAT State Machine: OP = Normal operation mode, mailbox- and process data communication possible

Enable

green

off

The motor control is blocked (Index 6010:02] is not set) or SM-L50 is not ready for operation

on

The motor control is activated (Index 6010:02] is set) or SM-L50 is ready for operation

Warning

yellow

off

No errors

on

Configuration error, e.g.:

  • Motor power supply not connected
  • 80°C temperature exceeded
  • 100% duty cycle reached
  • ...

Error A

red

on

Configuration error of output stage A, e.g.:

  • 100°C temperature exceeded
  • short circuit
  • ...

Error B

red

on

Configuration error of output stage B, e.g.:

  • 100°C temperature exceeded
  • short circuit
  • ...

Name

Signal

1

A

Encoder input A

2

C

Encoder input C (zero input). If object 7000:01 is set in the control word and a rising edge occurs at encoder input C, the current counter value is stored as a reference mark in the latch register.

3

Encoder supply +24V

Encoder supply (from positive power contact)

4

Input 1

Digital input 1 (24 VDC)

5

B

Encoder input B

6

Latch / Gate

Latch input. The current counter value is stored as a reference mark in the latch register, if

  • object 7000:02 is set and a rising edge occurs at the latch input; or
  • object 7000:04 is set and a falling edge occurs at the latch input.

7

Encoder supply 0V

Encoder supply (from negative power contact)

8

Input 2

Digital input 2 (24 VDC)
