7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
1211
Default value
500.0
Input of -3dB bandwidth for current setpoint filter 1 (band-stop). The filter is activated in
machine data MD 1200 (No. current setpoint filters) and MD 1201 (Type current setpoint filter).
Note:
When 0 is entered for the bandwidth, the filter is parameterized as a proportional element with
a gain of 1.
1212
Default value
0.0
Input of numerator bandwidth for the damped band-stop. When a value of 0 is entered, the
filter is initialized as an undamped band-stop. The filter is activated via machine data MD 1200
(No. setpoint current filters) and MD 1201 (Type current setpoint filter).
Note:
The value entered in MD 1212 (Numerator bandwidth current setpoint filter 1) must not be
higher than twice the value entered in MD 1211 (Bandwidth current setpoint filter 1).
1213
Default value
3 500.0
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 (No. current setpoint filters) and MD 1201 (Type
current setpoint filter).
Note:
The maximum block frequency input value is limited by the sampling frequency of the servo
control (MD 1000) (parameterization error).
