Function:
Select the type of output filter connected. This
parameter cannot be adjusted while motor is
running.

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

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

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 Capacitance Output Filter
and
14-57 Inductance Output Filter
have to be
programmed (these parameters have no effect in
VVC
plus
and U/f). The modulation patter will be set
to SFAVM which gives the lowest acoustic noise in
the filter. Remember to set
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).
