5.4 Parameterizing the 3RW52 soft starter
Requirements
● The 3RW52 soft starter is installed and connected.
● Rated control voltage and rated operational voltage have been applied.
● Suggested settings (Page 81)
Note
Tips for parameterizing the 3RW52 soft starter.
Entering the motor and load data in the
STS software (Page 17) will simulate the application
and a suitable 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 3RW52 soft starter.
Setting elements on the 3RW52 soft starter (Page 77)
2. Set the motor overload protection on setting elements "CLASS" and "I
e
". The scale for
rated operational current I
e
is listed for each connection type in the table on the front of
the 3RW52 soft starter.
Make sure that the arrow of the "CLASS" setting element points to the required setting.
Setting the Electronic motor overload protection (Page 99)
3. Set soft starting at the setting elements "t" and "U". (Page 93)
4. Set the current limit at the setting element "Current limiting value x I
e
".
Setting the Current limiting function (Page 96) of I
e
5. Set soft stopping at setting element "t". (Page 98)
6. Activate the Soft Torque function, if required.
Setting RESET MODE and Soft Torque (Page 83)
Soft Torque (Page 102)
7. Set the required RESET MODE. (Page 83)
8. Set the signal of your choice at the ON / RUN relay output. (Page 86)
Result
The 3RW52 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.
