Settings / Description
The input filter is used to suppress interfering mains
frequency signal components. The frequency depends on the
application location and can be set with module-level
granularity.
10 Hz The mains frequency is 10 Hz
The mains frequency is 50 Hz
50 Hz
*)
(e.g., Europe)
The mains frequency is 60 Hz
60 Hz
(e.g., North America)
200 Hz The mains frequency is 200 Hz.
The mains frequency is 400 Hz
400 Hz
(e.g., marine and aerospace)
You can choose between 2 filter modes:
In this filter mode, the interference
frequency is suppressed by a broadband
notch filter, including frequencies in the
sidebands.
precise Therefore, there is good interference
suppression even at higher frequencies
(> 40 dB, low pass). However, a 3×
conversion time compared to the "fast" filter
mode has to be accepted.
The interference suppression in this filter
mode is precisely optimized for the set filter
frequency; the attenuation decreases in the
fast *) sidebands. Higher frequencies are not
attenuated as much as in the "precise" filter
mode. In return, the conversion time is
significantly shorter.
