Setting Reset Mode And Soft Torque - Siemens SIRIUS 3RW51 Equipment Manual

Note
Tips for parameterizing the 3RW51 soft starter
Entering the motor and load data in the STS software (Page 9) will simulate the application and
a suitable 3RW5 soft starter will be suggested. In addition, information regarding
parameterization is also provided.
Procedure
1. You set the parameters on the setting elements of the 3RW51 soft starter.
Setting elements on the 3RW51 soft starter (Page 71)
2. Set the motor overload protection on setting elements "CLASS" and "I
operational current I
soft starter and in the Technical Data (Page 161).
Make sure that the arrow of the "CLASS" setting element points to the required setting.
3. Set the soft starting at the setting elements "t" and "U". (Page 89)
4. Set the current limiting at setting elements "Current limitation value x I
5. Set soft stopping at setting element "t". (Page 94)
6. Activate the Soft Torque function, if required.
Note the information in chapters Setting RESET MODE and Soft Torque (Page 75) and
(Page 75)Soft Torque. (Page 97)
7. Set the required RESET MODE (Page 75).
8. Set the signal of your choice at the ON / RUN relay output (Page 78).
9. Set the parameters in chapter Functions under "Additional parameters" (Page 99) if desired.
Result
The 3RW51 soft starter has been parameterized and is ready to operate. You can parameterize
the signal of the analog output via an optional 3RW5 HMI High Feature. (Page 122)
