Harmonics controller

Harmonics in the line voltage cause harmonics in the line currents. Current harmonics can
be reduced by activating the harmonics controller.
Example: Setting the harmonics controller
The 5th and 7th harmonics are to be compensated:

The phase currents in parameter p0069[0..2] (U, V, W) can be checked using the STARTER trace
function.
