In
scenarios
where
the
running
frequency
of
the
AC
drive
need
not
be
adjusted
continuously
and only several frequencies are required
,
the multi
-
speed control can be used
.
The
VDF730
supports
a
maximum
of
eight
running
frequencies
,
which
are
implemented
by
state
combinations of three DI
terminals
.
Set the function codes corresponding
to DI
terminals
to
a
value
among
13
to
15
,
and
then
the
DI
terminals
are
specifed
as
the
multi
-
frequency
input terminals
.
The multiple frequencies are set based on the multi
-
frequency table in
group
P8
.
In
addition
,
you
need
to
set
P0

01
(

to

(

The
following

shows
how

In
the
preceding
fgure
,
DI3
,
DI2
and
DI1
are used
as
the
multi
-
frequency input
terminals
,
each of which has a bit value
.
The state combinations of these terminals correspond to
multiple frequencies
,
When
(
DI3
,
DI2
,
DI1
) = (
0
,
1
,
0
),
the state combination value is 2
,
corresponding to the value set in P8
-
02
.
The target running frequency is automatically
calculated
by
(
P8
-
02
)
x
(
P0
-
04
).
The
VDF730 supports a maximum
of
three
DI
terminals to be
used
as the
multi
-
frequency
input terminals
.
You can also use less than three DI terminals
,
and the empty bit is
considered
to
be
0
.

Setting
the
Motor
Rotating
Direction
After
the
AC
drive
restores
the
default
settings
,
press
RUN
to
drive
the
motor
to
rotate
.
In
this
case
,
the
rotating
direction
is
regarded
as
the
forward
rotation
.
If
the
rotating
direction
is
reverse
to
the
direction
required
by
the equipment
,
power
off the AC
drive
and
exchange any
two
of
the
output
UVW cables
(
wait
until the
main capacitor of the
AC
drive
is
completely
discharged
).
In
some
applications
where
both
forward
rotation
and
reverse
rotation
are
required
,
enable
the
reverse
control
(
P5
-
09
=
0
,
default
value
)
and
meanwhile
reverse
the
rotating
direction
by
setting
P0
-
12
to
1
.
Then
press
RUN
to
make
the
motor
rotate
in
the
reverse
direction
,
as
shown
in
the
following
fgure
.
