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).

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.
This setting is only for backwards compatibility. It
enables operation with FLUX control principle
when the parameters 14-56 Capacitance Output
Filter 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.
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 14-55 Output Filter to
Sine-wave fixed always when you use a sine-wave
filter.
Function:
[0.1 - 6500.0 uF] Set the capacitance of the
output filter. The value can be
found on the filter label.
NOTE
This is required for correct
compensation in Flux mode
(1-01 Motor Control Principle)
Function:
[0.001 - Set the inductance of the output
filter. The value can be found on the
filter label.
