8.10 Response to bus errors / Control via digital input
Requirements
Ⴠ 3RW52 soft starter from firmware version V2.0.1
Note
3RW52 soft starter with firmware version earlier than V2.0.1:

Operating principle
The parameter "Control via digital input" is only relevant when using a
3RW5 communication module. The parameter is helpful, for example, for applications in
which the bus connection serves mainly for observation and monitoring purposes.
The parameter defines how the master control function behaves on failure of the bus
connection or a CPU stop. A failure of the bus connection or a CPU stop can also occur in
the operating mode "manual - local", for example when observing or monitoring via the bus
connection. You can use the parameter to disable a switchover to the "Automatic" mode and
operating mode "manual - bus".
