Use
of
the
PG
Terminal
The
closed
-
loop
vector
control
with
sensor
(
P0
-
01
=
1
)
helps
to
improve
the
speed
stability
accuracy
of the AC
drive
.
In this
case
,
it is
necessary to
install
an encoder for
the
motor
.
Signals
from
the encoder are
fed back
to
the AC drive
through
the PG card
.
The
VDF650
provides
PG
cards
of
four
different
types
of
signal
features
.
The AC drive supports four types of encoders
,
differential encoder
,
UVW encoder
(
wire
-
saving
UVW
encoder
),
resolver
,
open
-
collector
encoder
.
The
setting
of
encoder
parameters
varies
with
the
actually
used
encoder
type
.
Here
takes
motor

parameters
as
an
example
for
description
.
•
For
the
differential
encoder
,
set
P1
-
27
(
Encoder
pulses
per
revolution
)
and
set
P1
-
28
to
0
(
ABZ
incremental
encoder
).
•
For
the
UVW encoder
,
set
P1
-
27
(
Encoder
pulses
per revolution
)
and
set
P1
-
28
to
1
(
UVW
incremental
encoder
).
•
For
the
resolver
,
set
P1
-
28
to
2
(
Resolver
).
•
For
the
open
-
collector
encoder
,
set
P1
-
27
(
Encoder
pulses
per
revolution
)
and
set
P1
-
28
to
0
(
ABZ
incremental
encoder
).
•
For
the
wire
-
saving
UVW
encoder
,
set
P1
-
27
(
Encoder
pulses
per
revolution
)
and
set
P1
-
28
to
4
(
Wire
-

UVW
encoder
).

Use
of
Serial
Communication
When communication mode RS485
,
Profibus
-
DP or CANopen are adopted
,
you need
to install a corresponding extension card on the VDF650 series AC drive
,
and set P0
-
28
correctly
according to
the
used
communication
protocol
type
.
CAN
-
link
is
enabled
by
default
and
you
need
not
select
it
.
For
the
confguration of
hardware
communication
parameters for the communication port
,
see
group
PD
.
Set
the
communication
rate
and
data
format
to
consistent
with
those
of
the
host
computer
,
which
is
the
precondition
of
normal
communication
.
The
VDF650
serial
port
itself
supports
the
Modbus
RTU
slave
communication
protocol
.
You
can
query
or
modify
the
AC
drive
'
s
function
codes
,
query
various
running
state
parameters
,
and
send
running
command
and
running
frequency
to
the
AC
drive
from
the
host
computer
through
the
serial
port
.
