Harmonics controller

Description
Harmonics in the supply 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 harmonic are to be compensated:

0% scaling means that the harmonics controller has been deactivated.
100 % scaling means that the harmonics controller has been activated with standard gain.
The phase currents in parameter p0069[0...2] (U, V, W) can be verified using the STARTER
trace function.
Parameters
• r0069[0...6]
