If the Active Infeed is operated according to the factory setting, i.e. with a line-side power
factor of cosφ
can be simplified to

The Active Infeed must now be selected such that the permissible line current of the Active
Infeed is greater than or equal to the required value I

Positioning in a specified time

Predefinitions
In the case of positioning in predefined time, only the end points of the path and the duration
of the individual motion sections are predefined.
Objective
An appropriate primary section of the peak and continuous load motors in the 1FN3 product
family, the matching secondary sections and the number of required secondary sections are
to be found for the following specifications:
The motor is to move on a horizontal axis during time Δt
