Input of block frequency for speed setpoint filter 1 and parameterization as simple band-stop
filter. The filter is activated via machine data MD 1500 (number of setpoint filters) and MD
1501 (type speed setpoint filter). The machine data MD 1516/MD 1519 (bandwidth numerator
speed setpoint filter) and MD 1520/MD 1521 (band-stop filter natural frequency speed setpoint
filter) keep their default values.

of resonance)
fbn = MD 1515/1518 Bandwidth denominator filter 1/filter 2 [Hz]
fbz = MD 1516/1519 Bandwidth numerator filter 1/filter 2 [Hz]
