The
factory
setting
of
carrier
frequency
varies
with
the
AC
drive
power
.
If
you
need
to
modify
the carrier
frequency
,
note
that
if the
set
carrier frequency
is
higher than factory
setting
,
it
will
lead
to
an
increase
in
temperature
rise
of
the
AC
drive
'
s
heatsink
.
In
this
case
,
you
need
to
de
-
rate
the
AC
drive
.
Otherwise
,
the
AC
drive
may
overheat
and

It is used to
set whether the
carrier frequency
is adjusted
based on
the temperature
.
The
AC drive automatically reduces the carrier frequency when detecting that the heatsink
temperature
is
high
.
The
AC
drive
resumes
the
carrier
frequency
to
the
set
value
when
the
heatsink
temperature
becomes
normal
.
This
function
reduces
the
overheat
alarms
