9. The activated current setpoint filters must then be subsequently parameterized.
Current setpoint filter Setting in the parameter area
1 ... 4
p1657 to p1676
5 ... 10 p5201 to p5230
For each activated current setpoint filter, parameterize the following values:
–
Type
– Denominator natural frequency
– Denominator damping
– Numerator damping
As long as the parameter setting p1699 = 1 is active, the background calculation of the
filter data is not performed, even when filter parameters are changed.
Note
The set parameter values of the current setpoint filters 5 to 10 are lost if you deactivate
the extended current setpoint filters again in the Properties dialog.
10.Make the setting p1699 = 0 to start calculating the filter data.
11.Then save the modified project settings.
Parameterization example
Four current setpoint filters connected in series can be parameterized as follows, for
example:
● Lowpass 2nd order (PT2: -40 dB/decade) (type 1)
● General filter 2nd order (type 2)
● Bandstop
● Low-pass with reduction by a constant value
Bandstop and low-pass with reduction are converted into the parameters of the general
2nd order filter via the STARTER commissioning tool.
