5.7 Current setpoint filter
The current setpoint filters 1 to 4 are activated by default. If more than 4 current setpoint filters
are required, you can activate current setpoint filters 5 to 10 in offline mode in the object
properties of the drive.
Activating and setting current setpoint filters 5 to 10
To activate and to set current setpoint filters 5 to 10, proceed as follows:
1. Mark the desired servo drive in the project navigator and open the "Properties" context
menu.
The "Object Properties" dialog opens.
2. Click the "Function modules" tab.
3. Activate the "Extended current setpoint filters" function module in the function modules
selection with a mouse click.
4. Download the data to the target system.
5. Select group parameter p1656[0] online and open the sub categorization.
6. Select the required current setpoint filter (e.g. P1656[0].0) - and in the drop-down list of the
parameter line, select setting "[1] Active".
Repeat this procedure for every speed setpoint filter that you wish to additionally activate.
7. Select group parameter p5200[0] and open the sub-categorization.
8. Select the required additional current setpoint filter, in the parameter line, open the value
selection and select setting "[1] Active".
Repeat this procedure for every additional speed setpoint filter that you wish to activate.
9. The activated current setpoint filters must then be subsequently parameterized.
For each activated current setpoint filter, parameterize the following values:
– Type
– Denominator natural frequency
– Denominator damping
– Numerator damping
– Numerator natural frequency
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.
