Activation options
If the "Emergency run" parameter is set to "Manually enable/disable", you can activate and
deactivate the emergency run in the event of a failed power semiconductor as follows:
• 3RW5 HMI High Feature
Menu: "Control > Enable / Disable emergency run"
Access protection to the 3RW5 HMI High Feature is not active or has been reset.
Refer to chapter Control via 3RW5 HMI High Feature (Page 232).
• With SIRIUS Soft Starter ES (TIA Portal) via the local interface on the 3RW5 HMI High Feature
Brief overview: Window "Task Card" > Tab "Online Tools" > "SIRIUS Control Panel"
• With a fieldbus via a 3RW5 communication module:
– With SIRIUS Soft Starter ES (TIA Portal) Premium / Professional (only via a 3RW5 PROFINET
or PROFIBUS communication module)
Brief overview: See SIRIUS Soft Starter ES (TIA Portal) via the local interface on the
3RW5 HMI High Feature
– Configuration software of the control system (e.g. STEP 7 with corresponding HSP)
– With the commands "Enable emergency run" or "Disable emergency run" in data record 93
You can find additional information on the parameters that can be set via the fieldbus in the
manual of the respective 3RW5 communication module.

Overview of the input functions
Operating principle
The 3RW55 and 3RW55 Failsafe soft starters have 4 digital inputs DI1 ... DI4 to which you can
assign an input action. The 3RW55 Failsafe soft starter also has a failsafe digital input (F‑DI). This
input cannot be parameterized.
Inputs with the input actions "Motor CW with PSx" or "Motor CCW with PSx" have AND
connection. If multiple inputs are assigned the same input action (e.g. Input 1 and Input 2 are
assigned the input action "Motor CW with PS1"), all of these inputs have to be activated for the
start command to be accepted.
Inputs with other input actions have OR connections. If multiple inputs are assigned the same
input action (e.g. Input 1 and Input 2 are assigned the input action "Emergency start"), only one
of these inputs has to be activated for the function to be executed.
Requirements
You can only modify an input action if the relevant input is not active.
