Parameter Descriptions
14-52 Fan Control
Option: Function:
Select the minimum speed of the
main fan.
[0] Auto Select [0] Auto to run the fan only
*
when the internal temperature of
the frequency converter is in the
range 35 °C (95 °F) to approxi-
mately 55 °C (131 °F). The fan runs
at low speed at 35 °C (95 °F) and
at full speed at approximately 55 °C
(131 °F).

14-53 Fan Monitor
Option: Function:
Select the frequency converter
action if a fan fault is detected.

14-55 Output Filter
Option: Function:
NOTICE
This parameter cannot be
adjusted while the motor is
running.
NOTICE
Reset the frequency converter
after selecting [2] Sine-Wave
Filter Fixed.
OVERHEATING OF
FREQUENCY CONVERTER
When using sine-wave filters,
there is a risk of overheating
of the frequency converter,
which can result in personal
injury and equipment damage.
Always set
parameter 14-55 Output Filter
to [2] Sine-wave fixed when
using a sine-wave filter.
Select the type of output filter
connected.

14-55 Output Filter
Option: Function:
[0] No Filter This is the default setting and
*
should be used with dU/dt filters or
high-frequency common-mode (HF-
CM) filters.
[2] Sine Wave This parameter sets a minimum
Filter Fixed allowed limit to the switching
frequency and ensures that the
filter is operated within the safe
range of switching frequencies.
Operation is possible with all
control principles. For flux control
principle, program
parameter 14-56 Capacitance Output
Filter and
parameter 14-57 Inductance Output
Filter (these parameters have no
effect in VVC
modulation pattern is set to SFAVM,
which gives the lowest acoustic
noise in the filter.
