Filter types
The graphical user interface for the display and processing of filters actively available in the
SINAMICS converter can be found under "Active filter":
Filter type
PT1 low pass
PT2 low pass
General 2nd order
Band-stop (notch)
Low-pass with re‐
duction
*) A negative value is often set here in order to attain attenuation of the notch frequency.
Automatic generation and representation of frequency response functions (dB amplitude and
degree phase compared to frequency) provides the user with immediate feedback for each
filter parameter. The units for the filter type and the limits for the parameters are defined directly
by the metadata for the corresponding drive parameters.
Example: "Active filters"
The new values become active in the drive with softkey "Accept".
The values are saved in the drive and backed up in the drive archive with softkey "Save drive
object".
