An error counter has reached
or exceeded the warning level.
Local Error
r-0-0-0-0-0 (grid 200 ms)
Local error; Device has inde-
pendently changed status from
OPERTIONAL to SAFE-OPER-

SafeOPError due to a syn-
chronisation error.

7.3.1.1 Synchronous communication mode
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.
