p1655[0...1]
CI: Current setpoint filter natural frequency tuning / I_set_filt f_n
VECTOR (n/M)
Can be changed: U, T
Data type: Unsigned32
P-Group: Control
Min
-
Description:
Sets the signal source for tuning the natural frequency of the current setpoint filter.
Index:
[0] = Filter 1
[1] = Filter 2
Note:
[0] = Filter 1
[1] = Filter 2
p1656[0...n]
Activates current setpoint filter / I_set_filt active
VECTOR (n/M)
Can be changed: U, T
Data type: Unsigned16
P-Group: Control
Min
0000 hex
Description:
Activates current setpoint filters 1 to 2.
Bit field:

Signal name
00
Filter 1
01
Filter 2
Dependency:
The current setpoint filters are parameterized with p1656 to p1666.
Note:
If not all of the filters are required, then the filters should be used consecutively starting from filter 1.
p1657[0...n]
Current setpoint filter 1 type / I_set_filt 1 Typ
VECTOR (n/M)
Can be changed: U, T
Data type: Integer16
P-Group: Control
Min
1
Description:
Sets the current setpoint filter 1 as low pass (PT2) or as extended general 2nd-order filter.
Values:
1:
2:
Dependency:
The current setpoint filters are parameterized with p1656 to p1676.
Note:
For an extended general 2nd order filter, by inserting the same natural frequency in both the numerator and in the
denominator, i.e. bandstop frequency, a bandstop filter is implemented. If the numerator damping of zero is
selected, the bandstop frequency is completely suppressed. The numerator damping can be determined from the
equation for the 3 dB bandwidth: f_3dB bandwidth = 2 * D_numerator * f_bandstop frequency.

0.5 [Hz]
Description:
Sets the denominator natural frequency for current setpoint filter 1 (PT2, general filter).
Dependency:
The current setpoint filters are parameterized with p1656 to p1676.
