The inverter has to be informed about whether the main window settings or the auxiliary
window settings must be used. This is done by the ‘Activate’ flag
[/Welcome/Settings/Customer set/Activate].
Possible values for this flag are given in
By default the inverter uses the main
inverter settings.

The inverter can have three types of effect on the network:
−
Inverter the selected harmonics until their magnitudes are close to zero
(Maximum filtering)
−
Inverter the selected harmonics until their magnitudes reach the residual level
permitted by the user (filtering to Curve)
−
Produce or absorb reactive power including load balancing
The user can put the emphasis on one of the above effects by selecting the filtering
mode.
