A
The
output
frequency
increases
or
decreases
along
the
S
curve
.
This
mode
is
generally
used
in
the
applications
where
start
and
stop
processes
are
relatively
smooth
,
such
as
elevator
and
conveyor

In

This
mode
is
usually used
in applications
where
acceleration

required at
the
speed
higher
than
the
rated
frequency
.
When the set frequency is higher than the rated frequency

t2
is
the time defned in P4
