RUN

green

This LED indicates the terminal's operating state:

off

State of the EtherCATClosed ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs 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

C

Encoder input C (zero input). If object 7000:01 is set in the control word and a rising edgeClosed A rising edge is the transition of a digital signal from low to high. It is also called positive edge occurs at encoder input C, the current counter value is stored as a reference mark in the latch register.

LatchClosed The control word is used to activate the drive's latch status machine. The latch control word is processed independently of the EtherCAT bus cycle. The status word is used to return the drive's latch status

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.
