Harmonics Controller - Siemens Sinamics S120 Function Manual

1.1.7

Harmonics controller

Description
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.
