Description
parameter 14-57 Inductance Output Filter
. Setting the option allows the modulation pattern to be set to stator
flux asynchronous vector modulation (SFAVM), which reduces the acoustic switching noise from the filter.

ALL-MODE FILTERING
Enables all-mode filter operating condition and ensures that the filter is operated within the safe range of
switching frequencies.
Use this setting only for VLT® MCC 201 All-Mode Filters.
When setting the option for VLT® MCC 201 All-mode Filter, the parameter enables all-mode filter operating
conditions, which include settings for a minimum allowed limit to the switching frequency and ensure the
filter is operated within the safe range of switching frequencies.
The option supports all control principle operations of the filter. Set
Parameter 14-56 Capacitance Output Filter
and
parameter 14-57 Inductance Output Filter
.
Setting the option allows the modulation pattern to be set to stator flux asynchronous vector modulation
(SFAVM), which reduces the acoustic switching noise from the filter.

Set the C
y
(capacitance) value of the output filter in uF, when using VLT® MCC 101 Sine-wave filter and VLT® MCC 201 All-mode filter.
See the filter product label for the capacitance value. The value is the equivalent star-connected capacitance of the filter. When the
filters are installed in parallel, enter the combined capacitance value of the paralleled filter. The value is the equivalent star-connec-
ted capacitance (C
y
) of the filter multiplied by the number of installed paralleled filters.
