A rule of thumb for selecting the primary section is as follows:
In this particular example, the quotient F
duty cycle, the peak load motor has sufficient reserves with its maximum force F
effective force F
Without taking other decision-making criteria into account, the peak load motor 1FN3150-
4WC00-0BA1 is the most suitable for the specified duty cycle and is therefore used for the
following calculations.
Specifying the number of secondary sections
Type of secondary section
Based on the article number, a search is made for the appropriate secondary section for
primary section 1FN3150-4WC00-0BA1. It has the order designation 1FN3150-4SA00-0AA0.
