Current setpoint filters

Activate and set current setpoint filter
The current setpoint filters 1 to 4 are available as standard. You can activate the current
setpoint filters 5 to 10 offline in the object properties of the drive.
1. Mark the desired servo drive in the project navigator and open the "Properties" context
2. Click the "Function modules" tab.
3. Activate the "Extended current setpoint filters" function module in the function modules
4. Download the data to the target system.
The individual current setpoint filters are activated via various parameters (Page 109). The
parameter values of the activated filters can then be set:
Current setpoint filter
Current setpoint filters 1 to 4
Current setpoint filters 5 to 10 p5200[0...n].1 = 1
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.
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. Only with parameter setting
p1699 = 0, is the calculation performed.
Parameterization example
Four current setpoint filters connected in series can be parameterized as follows, for
example:
● Low-pass 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.
