Description of choice:
In some cases this dynamic compensation can cause
resonance’s in the DC link and should then be disa-
bled. Typical cases are where a line choke or a passive
harmonic filter (e.g. filters AHF005/010) is mounted in
the mains supply to the frequency converter to sup-
press harmonics. Can also occur on mains with low
short circuit ratio.
