Communication
control
The
most
common
confguration
is
when
the
host
computer
is
used
to
control
running
of the AC drive by means of communication
,
such as the RS485
,
PROFIBUS
-
DP
,
CANlink
,
and
CANopen
.
The
VDF650 interacts with the user programmable card also by
means
of
communication
.
Install
a
matching
communication
card
in
the
multifunction
extension
port
,
and
set
P0
-
02
to
2
.
Then
,
you
can
start
or
stop
the
AC
drive
in
communication
mode
.
The
following
fgure
shows
the
setting
method
.

When
FD

is
set
to
a
non
-
zero
number
,
the
function
of
automatic
AC
drive
stop
upon
communication
timeout
is
enabled
.
This
prevents
uncontrollable
AC
drive
running
due
to
faults
of
the
communication
cable
or
the
host
computer
.
The
communication
port
of
the AC drive supports
the
Modbus
-
RTU
protocol
,
and
the
communication is implemented only when the host computer supports the Modbus
-
RTU
master
station
protocol
.

Start
Mode
The VDF650 supports three start modes
,
namely
,
direct start
,
rotational speed tracking
restart
,
and
pre
-
excited
start
(
asynchronous
motor
),
set
in
P6
-

.
•

(
direct
start
)
It
is
applicable
to
small
-
inertia
load
.
The
frequency
curve
in
this
mode
is
shown
in
the
following
fgure
.
DC
braking
before
the
start
is
applicable
to
drive of
load
such
as
elevator
and
crane
.
Startup frequency is applicable to drive with burst start under start torque
,
such as
cement
mixer
.
