04.96
1214
Default value
500
Input of 3dB bandwidth for current setpoint filter 2 (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.
1216
Default value
3 999.0
Input of block frequency for current setpoint filter 3 (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).
