This is the default setting and should be used with
dU/dt filters or high frequency common mode (HF-
CM) filters.

Sine-

Filter
This setting is only for backwards compatibility. It
enables operation with FLUX control principle when
the parameters 14-56 and 14-57 are programmed
with the output filter capacitance and inductance. It
DOES NOT limit the range of the switching
frequency.

Sine-

Filter
Fixed
This parameter sets a minimum allowed limit to the
switching frequency and ensures that the filter will
be operated within the safe range of switching
frequencies. Operation is possible with all control
principles. For FLUX control principle the
parameters 14-56 and 14-57 have to be
programmed (these parameters have no effect in
VVC+ and U/f). The modulation patter will be set to
SFAVM which gives the lowest acoustic noise in the
filter. Remember to set parameter 14-55 to Sine-
wave fixed always when you use a sine-wave filter.
14-56 Capacitance Output Filter
Compensation function of the LC filter requires the per phase
equivalent star connected capacitance of the filter (3 times the
capacity between two phases when capacitance is ’Delta’
connection).
