0...7 index of the parameter set
Minimum: Maximum:
10.0 7999.0
0...7 index of the parameter set
Minimum: Maximum:
5.0 7999.0
Note
The bandwidth must be smaller or equal to 2 x MD 5514 x MD 5520.
[n] 0...7 index of the parameter set
Minimum: Maximum:
0.0 7999.0
Note
Setting a value of 0 (MD 5516) initializes the filter as an undamped band-stop.
The value set in MD 5516 must not exceed twice the value set in MD 5515.
0...7 index of the parameter set
Minimum: Maximum:
1.0 141.0
The natural frequency for the general band-stop is set in MD 5520 as a percent-
age of MD 5514 (blocking frequency).
Note
Setting MD 5520=100% initializes the filter as an undamped band-stop.
The natural frequency in Hz of the filter must be less than the reciprocal value
fo two velocity controller cycles
(MD 5520@0.01@MD 5514<1/(2@MD 5001@31,25 µs).
