5514
SPEED_FILTER_1_SUPPR_FREQ [n] 0...7 index of the parameter set
Cross reference: -
Band-stop filter blocking frequency for velocity filter 1
Related to:
HLA
Protection level:
3/3
Unit:
Hz
Default:
3500.0
Minimum:
10.0
Maximum:
7999.0
Data type:
FLOAT
Active:
Immediately
5515
SPEED_FILTER_1_BANDWIDTH [n] 0...7 index of the parameter set
Cross reference: -
Band-stop filter bandwidth for velocity filter 1
Related to:
HLA
Protection level:
3/3
Unit:
Hz
Default:
500.0
Minimum:
5.0
Maximum:
7999.0
Data type:
FLOAT
Active:
Immediately
Note
The bandwidth must be less than or equal to 2 x MD 5514 x MD 5520.
5516
SPEED_FILTER_1_BW_NUMERATOR [n] 0...7 index of the parameter set
Cross reference: -
Bandwidth numerator of velocity filter 1
Related to:
HLA
Protection level:
3/3
Unit:
Hz
Default:
0.0
Minimum:
0.0
Maximum:
7999.0
Data type:
FLOAT
Active:
Immediately
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.
5520
SPEED_FILTER_1_BS_FREQ [n] 0...7 index of the parameter set
Cross reference: -
Band-stop filter natural frequency for velocity filter 1
Related to:
HLA
Protection level:
3/3
Unit:
%
Default:
100.0
Minimum:
1.0
Maximum:
141.0
Data type:
FLOAT
Active:
Immediately
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 of two
velocity controller cycles
(MD 5520@0.01@ MD 5514<1/(2@MD 5001@31.25 µs).
5522 ACT_SPEED_FILTER_TIME Cross reference: -
Time constant for actual velocity filter 1
Related to:
HLA
Protection level:
3/3
Unit:
ms
Default:
0
Minimum:
0
Maximum:
0
Data type:
UNS.WORD
Active:
Power On
Note
MD 5522 performs no function and is only compatible with the electric drives.
