14-55 Output Filter
Option: Function:
Select the type of output filter connected. This
parameter cannot be adjusted while motor is
running.
[0]
*
No
Filter This is the default setting and should be used with
dU/dt filters or high-frequency common-mode (HF-
CM) filters.
[1] Sine-
Wave
Filter 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.
[2] Sine-
Wave
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
14-55 Output Filter 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).

[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 (

[0.001 -
65.000 mH] Set the inductance of the output

3.15.7 14-7* Compatibility
The parameters in this group are for setting of compatibility
for VLT 3000, VLT 5000 to FC 300.
14-72 VLT Alarm Word
Option: Function:
[0] 0 - 4294967295 Read out the alarm word corresponding to
VLT 5000.
14-73 VLT Warning Word
Option: Function:
[0] 0 - 4294967295 Read out the warning word corresponding to
VLT 5000.

[0 - 4294967295 ] Read out the ext. status word
corresponding to VLT 5000
3.15.8 14-8* Options
14-80 Option Supplied by External 24VDC
Option: Function:
[0] No Select No [0] to use the frequency converter's 24V DC
supply.
[1]
*
Yes Select Yes [1] if an external 24V DC supply will be used
to power the option. Inputs/Outputs will be galvanically
isolated from the drive when operated from an external
supply.
NOTE
This parameter is only changing function by performing a
power cycle.
14-89 Option Detection
Selects the behaviour of the frequency converter when a change in
the option configuration is detected.
Option: Function:
[0]
*
Protect Option
Config. Freezes the current settings and
prevents unwanted changes when
missing or defective options are
detected.
[1] Enable Option
Change Changes drive settings and is used
when modifying the system configu-
ration. This Parameter setting will
return to [0] after an Option Change.
