Siemens PROFINET SIRIUS 3RW5 - Sets the Operating Mode

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 "Operating mode manual - local" is
parameterized and activated.
Example of a 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".
Additional information
Further information on the 3RW5 soft starters and restoring the factory settings of the device
can be found in the Equipment Manual of the respective 3RW5 soft starter.
3.5.2 Sets the operating mode
Basic behavior when the operating mode is changed
A higher-priority mode can fetch control from a lower-priority mode at any time; the reverse is
not possible. The master control function can only be returned to the mode with the lowest
priority. Control sources with higher priority must take the master control function from the
mode with the lowest priority.
Requirement
A mode with lower priority can only take the master control function back while the motor is
switched o󹪜.
