Input of damping for current setpoint filter 4 (PT2 low-pass). The filter is activated via machine
data MD 1200 (No. current setpoint filters) and MD 1201 (Type current setpoint filter).

Input of block frequency for current setpoint filter 1 (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).
