Parameterizing the 3RW50 soft starter

Requirements
● The 3RW50 soft starter is mounted and connected.
● Rated control voltage and rated operational voltage have been applied.
● Suggested settings (Page 94)
Note
Tips for parameterizing the 3RW50 soft starter.
Entering the motor and load data in the STS software (Page 23) 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 3RW50 soft starter (Page 91).
2. Set the motor overload protection on the setting elements "CLASS" and "I
(Page 126). The scale for rated operational current I
in the table on the front of the 3RW50 soft starter.
Make sure that the arrow of the "CLASS" setting element points to the required setting.
3. Set the soft starting on the setting elements "t" and "U" (Page 119).
4. Set the current limit at the setting element "Current limiting value x I
5. Set the soft stopping on the setting element "t" (Page 125).
6. Activate the Soft Torque function, if required.
Note the information in chapters Setting RESET MODE and Soft Torque (Page 96) and
Soft torque (Page 130).
7. Set the required RESET MODE (Page 96).
8. Set the signal of your choice at the ON / RUN relay output (Page 99).
9. Set the parameters in Chapter Additional parameters (Page 136) if desired.
Result
The 3RW50 soft starter has been parameterized and is ready for operation. You can
parameterize the signal of the analog output via an optional 3RW5 HMI High Feature
(Page 111).
