18.3 Emitted Harmonics on Mains Current and Mains Voltage
18.3.1 General Information
Due to their electric design, the drive controllers and supply units generate
harmonics in the mains current and on the mains voltage during operation at
the mains. Using appropriate mains chokes decisively influences power fac‐
tors and mains harmonics.
18.3.2 Harmonics of Mains Current
Harmonics of Supply Units, In‐
feeding (HMV…E and HCS)
The harmonics of the mains current are decisively reduced by the
use of mains chokes.
For mains with mains frequency f
LN
= 60 Hz, the values accord‐
ingly are multiples of f
LN
= 60 Hz.
Formulas see chapter "Calculations".
