A rule of thumb for selecting the primary section is as follows:
In this particular example, the quotient F
L,max
/ F
eff
is equal to 2.1. For peak force F
L,MAX
of the
duty cycle, the peak load motor has sufficient reserves with its maximum force F
MAX
. The
effective force F
eff
is substantially below the rated force F
N
of the continuous load motor.
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.

⇒ l

= 420 mm + 260 mm = 680 mm
⇒ Number of secondary sections = 6
Selecting the power module
The selected peak load motor has the following data:
F

= 3300 N
F
N
= 1350 N
I
MAX
= 38.2 A
I

= 14.3 A
A suitable power module for this data is selected from the relevant catalog.
