7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
Note:
When 0 is entered for the bandwidth, the filter is parameterized as a proportional element with
a gain of 1.

Input of the band-stop filter natural frequency for raising or lowering the amplitude response
after the blocking frequency (MD 1514/1517).
The machine data (MD 1520/MD 1521) are used to match different axis dynamic responses to
a standard dynamic response (low-pass filter). The standard dynamic response is based on
that of the axis with the lowest resonant frequency.
