Real-time information (distributed clock)

0x2580 - ECAT DC: Real-time information

All time information provided in this object is based on UTC and transmitted in the format defined by EtherCAT for

this purpose: In nanoseconds, at a width of 64 bits, based on a date of January 01, 2000, (2000-01-01) and a time of

00:00.

There are various ways for the i700 servo inverter to receive its real-time information from the outside:

• From the (EtherCAT) master (DC synchronous in the EtherCAT state "Safe-Operational" or "Operational").

• By writing to subindex 4 (ECAT DC: Current time).

Info

0 No real-time information received yet

The i700 servo inverter has not yet received any real-time

information from the outside since switch-on.

• The i700 servo inverter is still operating with a time

which is based on the time when the device was

switched off last or which is based on the time stamp

of the firmware (whichever time is later).

1 Receive at least one piece of real-time

information

The i700 servo inverter has at least once received one

piece of real-time information from the outside since

switch-on.

• The first and the last time the i700 servo inverter has

received real-time information are displayed in

subindices 2 and 3.

2 Synchronous - cyclically updated

The i700 servo inverter receives cyclically updated real-

time information from the outside.

• The i700 servo inverter reports this status if it is e.g.

DC synchronous in the EtherCAT state "Safe-

Operational" or "Operational".

Subindex 2:

ECAT DC: Time stamp first real-time information

Display of the time when the i700 servo inverter received its first real-time information from the outside since

switch-on.

• In the "No real-time information received yet" status, a value of "0" is displayed.
