● 3RW52 soft starter from firmware version V2.0.1: The 3RW52 soft starter behaves in
accordance with the parameter "Control via digital input" (Page 35).
● 3RW55 and 3RW55 Failsafe soft starters: The 3RW55 soft starter behaves in accordance
with the parameter "Response to CPU/master stop" (Page 70).
If other connections to the control source are aborted, the master control automatically
switches back to the lowest priority of the current mode.
● "Automatic" mode: The 3RW5 soft starter responds as it does upon failure of the bus
connection or CPU stop.
● Operating mode "Manual - bus": Control switches to "Manual - bus - Connection abort".
● Operating mode "Manual - local": Master control switches either to
"Manual - local - Connection abort" or to "Manual operation local - input controlled". For
certain 3RW5 soft starters and parameter assignments, "Manual - local -
Connection abort" is not possible. In the following cases, control switches to
"Manual operation local - input controlled":
– 3RW50 soft starter
– 3RW52 soft starter
– 3RW55 and 3RW55 Failsafe soft starters: Input action
Example for 3RW55 soft starter: The 3RW5 HMI High Feature has master control. Input 2
is assigned the input action "Operating mode manual - local" and the input action is
activated. On a connection abort terminating the connection to the
3RW5 HMI High Feature, control switches to "Manual - local - input controlled".
