Drive functions
7.1 Servo control
Band-stop with infinite notch depth
Table 7- 3 Example of band-stop with infinite notch depth
STARTER filter parameters
Blocking frequency f = 500 Hz
Sp
Bandwidth (-3 dB) f = 500 Hz
BB
Notch depth K = -∞ dB
Reduction Abs = 0 dB
Simplified conversion to parameters for general order filters:
● Reduction or increase after the blocking frequency (Abs)
● Infinite notch depth at the blocking frequency
● Numerator natural frequency f
● Numerator damping D
● Denominator natural frequency f
● Denominator damping:
