11.2.1
Application examples for normal starting (CLASS 10) with 3RW30 and 3RW40
Recommended basic parameter settings
Assuming the conditions and constraints indicated below apply, the size of the soft starters
can be equivalent to the motor rating for a normal starting characteristic (CLASS 10).
You can find a suitable soft starter for the required motor rating based on the required startup
class in chapter Technical data [Page 121].
For typical applications where normal starting applies as well as recommended parameter
settings for the soft starter, refer to the table below.
1) Small fan: Mass inertia (centrifugal mass) of fan < 10 x mass inertia of motor
