7.3.2 Drive MD (data description)
Bandwidth current setpoint filter 3
1217
Default value Lower input limit Upper input limit Units
500.0 5.0 7 999.0 Hz
Active
at once
Input of -3dB bandwidth for current setpoint filter 3 (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.
Numerator bandwidth current setpoint filter 3
1218
Default value Lower input limit Upper input limit Units
0.0 0.0 7 999.0 Hz
Active
at once
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 1218 (Numerator bandwidth current setpoint filter 3) must not be
higher than twice the value entered in MD 1217 (Bandwidth current setpoint filter 3).
Block frequency current setpoint filter 4
1219
Default value Lower input limit Upper input limit Units
3 500.0 1.0 7 999.0 Hz
Active
at once
Input of block frequency for current setpoint filter 4 (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).
