Siemens SIRIUS 3RW55 - 7.11 Number of Parameter Sets

All further parameters are una󹪜ected by the activated automatic parameterization and can still
be parameterized. In this way, parameters, such as Starting mode or breakaway pulse, can be set
independently of the Automatic parameterization.
Interaction with use of a 3RW5 communication module
To prevent the learned parameters from being overwritten by the starting parameters of the
higher-level control on each system restart, activate the parameter "Parameters of CPU/master
disabled" (Page 214).
You can 󹪝nd further information on the parameter "Parameters of CPU/master disabled" in the
manual for the respective 3RW5 communication module.
Setting via 3RW5 HMI High Feature
• Menu: "Parameters > Soft Starter > Parameter set 1 / 2 / 3 > Automatic parameterization"
• Access protection to the 3RW5 HMI High Feature is not active or has been reset.
Procedure
To activate the Automatic parameterization, you must de󹪝ne the parameters "Rated operational
current I
e
" and "Application":
1. Set the rated operational current I
e
of the motor connected to the 3RW55 or 3RW55 Failsafe
soft starter.
If you have not yet set the rated operational current I
e
of the motor, the 3RW55 or 3RW55
Failsafe soft starter uses the stored value of the factory setting. After the automatic
parameterization has been activated, an input prompt pops up for the rated operational
current I
e
of the motor.
2. Choose the desired application with the menu item "Application".
3. If necessary, set the parameters "Mode", "Preset starting time" and "Current limiting value-
maximum".
4. Exit the menu for Automatic parameterization with the ESC key. Con󹪝rm the query "Save
parameter?" with the OK key.
Parameters
Parameters Description
Rated operational current I
e
Depending on the rated operational current I
e
of the motor connected to the 3RW55 or 3RW55
Failsafe soft starter.
Application Selection of all supported applications.
When selecting the application, the recommended start values for the parameters "Preset
starting time" and "Current limiting value - maximum" are used, depending on the application.
You can 󹪝nd these values in the "Advanced parameters" menu. Change these values as re‐
quired.
The recommended application parameters for the 󹪝rst start of the automatic parameterization
are rough values for guidance. Change these values as required.
