483 Dynamic DC link compensation
(DC LINK COMP.)
Value:
Off
[0]
✭
On
[1]
Function:
The frequency converter includes a feature, which
ensures that the output voltage is independent of
any voltage fluctuation in the DC link, e.g. caused
by fast fluctuation in the mains supply voltage. The
benefit is a very steady torque on motor shaft (low
torque ripple) under most mains conditions.
Description of choice:
In some cases this dynamic compensation can
cause resonance
’
s in the DC link and should then
be disabled. 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 suppress harmonics. Can also occur
on mains with low short circuit ratio.
