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
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 Set the capacitance of the
uF] output filter. The value can
be found on the filter label.
NOTE
This is required for
correct compensation in
Flux mode (1-01 Motor

Function:
[0.001 - Set the inductance of the output
65.000 mH] filter. The value can be found on
the filter label.
