Further parameters of the current setpoint filter adaptation and their purpose:
● p5281 = specifies which of the current setpoint filters is to be used for the adaptation
● p5282 = defines the lower limit frequency
● p5283 = defines the upper limit frequency
● p5284 = defines the activation threshold of the adaptation
● r5285 = displays the current blocking frequency
Note
Deviation with activated online tuning (p5300 = 2)
The denominator damping of the adapted filter is set automatically.
You can also overwrite this setting.
Activating the current setpoint filter adaptation
Note
Current setpoint filters 1 ... 4 are standard. The extended current setpoint filters 5 ... 10 can
be activated additionally (see Chapter " Extended current setpoint filters (Page 103)").
Several settings still have to be made or checked before activating the adaptation.
1. Parameterize the desired current setpoint filter as bandstop filter.
2. Assign the desired current setpoint filter to the adaptation via parameter p5281 (example
of filter 4: p5821 = 4).
3. Activate the adaptation via the setting p5280 = 1.
Note
If not all the requirements were satisfied before the adaptation was activated, fault F07419
"Drive: Current setpoint filter adaptation error" is output. The fault value indicates which
requirement has not been satisfied.
Deactivating the adaptation
The current setpoint filter adaptation can be deactivated in two ways:
1. Deactivate the adaptation. Set the following values:
– p5280 = 0 or
– p5280 = -1
