Manipulated Variable Filter - Siemens SINAMICS S120 System Manual

5.5.2

Manipulated variable filter

You activate the manipulated variable filter using parameter p1800.0 = 1. Entering a nominal
natural frequency = 0 or deactivating with p1800.0 = 0 deactivates the filter.
Note
The filter machine data must be assigned before the filter type is configured.
The type of manipulated variable filter is entered in parameter p1801.

Bit 0
The main filter data are defined using p1802, p1803 and p1804 up to p1805.
Enter the natural frequency for the manipulated variable filter (PT2 low-pass filter).
● Enter the damping for the manipulated variable filter (PT2 low-pass filter, p1803).
● Enter the numerator natural frequency for the manipulated variable filter (general 2nd
order filter, p1804)
● Enter the numerator damping for the manipulated variable filter (general 2nd order filter,
p1805)
