CAUTION
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
to
[2] Sine-wave fixed
when
using a sine-wave filter.
Select the type of output filter
connected.
[0]
*
No Filter
This is the default setting and
should be used with dU/dt filters or
high frequency common mode (HF-
CM) filters.

Sine-Wave
Filter
This setting is only for backwards
compatibility. It enables operation
when
parameter 14-56 Capacitance
Output Filter
and
parameter 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 is operated within the safe
range of switching frequencies.
14-55 Output Filter
Option:
Function:
Operation is possible with all
control principles. The modulation
pattern is set to SFAVM, which gives
the lowest acoustic noise in the
filter.

4.13.6 14-6* Auto Derate
This group contains parameters for derating the frequency
converter if there is high temperature.
14-60 Function at Over Temperature
Option:
Function:
If either heat sink or control card
temperature exceeds a factory-
programmed temperature limit, a
warning is activated. If the
temperature increases further, select
whether the frequency converter
should trip (trip lock) or derate the
output current.
[0]
*
Trip
The frequency converter trips (trip
lock) and generates an alarm. Cycle
power to reset the alarm. The
motor restarts when the heat sink
temperature has dropped below
the alarm limit.
[1]
Derate
If the critical temperature is
exceeded, the output current is
reduced until the allowable
temperature has been reached.
