7 Drive Machine Data (SIMODRIVE Drive MD) 04.96
7.2.2 FDD MD (data description - SW 3)
Bandwidth current setpoint filter 1
1211
Default value Lower input limit Upper input limit Units
500 0 1 000 Hz
Active
at once
Input of 3dB bandwidth for current setpoint filter 1 (band-stop). The filter is activated in
machine data MD 1200 and MD 1201.
Note:
When 0 is entered for the bandwidth, the filter is parameterized as a proportional element with
a gain of 1.
Block frequency current setpoint filter 2
1213
Default value Lower input limit Upper input limit Units
3 500.0 1 7 999.0 Hz
Active
at once
Input of block frequency for current setpoint filter 2 (band-stop). When block frequencies of <
10 Hz are input, the filter is deactivated (proportional element with a gain of 1). The filter is
activated via machine data MD 1200 and MD 1201.
Note:
The maximum block frequency input value is limited by the sampling frequency of the control
(MD 1000) (parameterization error).
