Operating Range Under Synchronous and Asynchronous Conditions for Voltage (V) and
Frequency (f)
Application and Setting Notes
Parameter: Synchronous operating mode, Asynchronous operating mode
•
Default setting (_:5041:119) Sync. operating mode = off
•
Default setting (_:5041:114) Async. operating mode= off
The operating modes of the stages can be activated or deactivated via the parameters. The operating modes
are deactivated in the default setting for safety reasons.
The following combination options are possible:
Sync. operating mode
Async. operating mode Description
on on
If the frequency difference is below the threshold
value set f-threshold ASYN<->SYN, the oper-
ating mode synchronous is active. In other cases, the
operating mode asynchronous is active.
If you wish to interconnect galvanically isolated
systems, then select this operating mode.
