Tab. 17: Error status list
The COMBIVERT with control board PRO supports a so-called synchronous com-
munication mode. This is titled differently for the different fieldbuses. In EtherCAT,
this functionality is managed under the term Distributed Clocks (DC).
Ultimately, the synchronous operating mode means that the internal interrupt grid
of the drive controller is synchronised to the synchronous signal generated by the
fieldbus.
The COMBIVERT with control board PRO does not support any values for the syn-
chronous cycle time. Which dependencies exist here and which parameters have
an influence can be found in the chapters "Switching frequency and derating" in the
programming manual.

Description
Local error; Device has inde-
pendently changed status from
OPERTIONAL to SAFE-OPER-
ATIONAL. Error bit is set to "1".
A watchdog error has occurred
in the application.
The red/green signals are shif-
ted by 180°. In case of overlap-
ping, red has priority.
Meaning
A communication or
device error has occurred.
The watchdog application
reports a timeout.
The fieldbus status has
changed due to an error.

Example
The device stops respond-
ing
Sync-Manager timeout
Device changes its
EtherCAT status from OP
to SafeOPError due to a
synchronisation error.
Change of status due to
register or object settings
that are not possible or in-
valid hardware configura-
tion.
Checksum error in the
flash memory of the ap-
plication controller.
