Automatic Parameterization - Siemens SIRIUS 3RW55 Manual

Automatic parameterization

Operating principle
When automatic parameterization is activated, the soft starter optimizes the starting
parameters each time the motor is started. The parameters are selected in such a way that
the motor starts immediately with minimum current and does not falter during run-up.
Automatic parameterization can be set for each of the parameter sets.
Once the parameters have been stored, you can view the automatically determined values in
the parameter settings of the respective parameter set. If you deactivate automatic
parameterization, the stored values are no longer modified. The parameters learned in the
device are only overwritten if the device is parameterized again.
Note
Prevent overwriting of the starting parameters with the parameter disable
If you insert a 3RW5 communication module (PROFIBUS or PROFINET) and activate a
parameter disable, you prevent the learned parameters from being overwritten by the
starting parameters during a system restart.
Note
Rated operational current I
Set the rated operational current I
parameterization.
If a rated operational current I
the automatic parameterization has been activated.
Note
Starting mode of the automatic parameterization
As long as the "automatic parameterization" function is active, the 3RW55 soft starter
monitors and analyzes the starting times and the starting currents at every start up.
The 3RW55 soft starter always sets the selected starting mode to "Soft starting with voltage
ramp and current limiting (Page 89)".
If another starting mode is required, deactivate the automatic parameterization and modify
the corresponding parameters.
