6.2.2 FILTER SIZING
The filter/drive coupling in the table is a standard coupling. In normal applications the filter
can be choosen according to the table. The filters can be undersized according to the size of
the modules in case of multi-axis application. This should be done not only because, as a
matter of fact, undersizing the filter means less money, but because the undersized filter
provides better performance to EMC.
Example:
- DBM PS 03 + DBM 03 5-5-5 + DBM 03 5-5-5 and contemporaneity factor of 0.8.
For this application it is not necessary to use the 100A filter of the table.
The reference current is Iin = 6

0.8 = 24 A
A 30A filter (FN 258-30/7) can safely be used.
