Direct
start
–
If the DC braking time is set to 0
,
the AC drive starts to run at the startup
frequency
.
–
If the DC braking time is not 0
,
the AC drive performs DC braking first and
then starts to run at the startup frequency
.
It is applicable to small
-
inertia load
application
where
the
motor
is
likely
to
rotate
at
startup
.

:
Rotational
speed
tracking
restart
The
AC
drive
judges
the
rotational
speed
and
direction
of
the
motor
frst
and
then
starts
at the tracked frequency
.
Such smooth start has no impact on the rotating motor
.
It
is applicable
to the restart upon instantaneous power failure of large
-
inertia
load
.
To
ensure
the
performance
of
rotational
speed
tracking
restart
,
set
the
motor
parameters
in
group
P1
correctly
.

start
(
asynchronous
motor
)
It
is
valid
only
for
asynchronous
motor
and
used
for
building
the
magnetic
feld
before
the
motor
runs
.
For
pre
-

current
and

time
,
see

of
P6

and
P6

.
–
If
the
pre
-
excited
time
is
0
,
the
AC
drive
cancels
pre
-
excitation
and
starts
to
run
at
startup
frequency
.
–
If the pre
-
excited time is not 0
,
the AC drive pre
-
excites first before startup
,
improving
the
dynamic
response
of
the
motor
.
