Op- Name Description
tion
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.

This option is only available in FC 302.
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.
Parameter 14-56 Capacitance Output Filter
Table 747: Parameter 14-56 Capacitance Output Filter
14-56 Capacitance Output Filter
Default value: 2.0 uF
Conversion index: -
Set the C (capacitance) value of the output filter in uF, when using VLT® MCC 101 Sine-wave filter and VLT® MCC 201 All-mode filter.
y
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 ) of the filter multiplied by the number of installed paralleled filters.
y
SETTING FOR VLT® MCC 101 SINE-WAVE FILTER AND VLT® MCC 201 ALL-MODE FILTER
Enables accurate flux compensation when option [2] Flux sensorless or option [3] Flux w/motor feedback is selected in parameter
1-01 Motor Control Principle.
-
Enter the correct capacitance value of the connected filter.
Parameter 14-57 Inductance Output Filter
Table 748: Parameter 14-57 Inductance Output Filter
14-57 Inductance Output Filter
Default value: 7
Conversion index: -
Set the inductance of the output filter in mH, when using VLT® MCC 101 Sine-wave Filter and VLT® MCC 201 All-mode Filter. See the
product label of the filter for the value of inductance. When filters are installed in parallel, enter the combined inductance value of
