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).
Range: Function:
Size related* [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)
14-57 Inductance Output Filter
Range: Function:
Size related* [0.001 -
65.000 mH]
Set the inductance 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)
3.15.6 14-7* Compatibility
The parameters in this group are for setting of compati-
bility 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.

Range: Function:
0 * [0 - 4294967295 ] Read out the ext. status word
corresponding to VLT 5000
3.15.7 14-8* Options
14-80 Option Supplied by External 24VDC
Option: Function:
[0] No
Select [0] No to use the frequency converter's 24 V DC
supply.
[1] * Yes
Select [1] Yes if an external 24 V 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.
14-90 Fault Level
Option: Function:
[0] * Off Use this parameter to customize Fault levels. Use
[0] Off with caution as it will ignore all Warnings
& Alarms for the chosen source.
