These
parameters
are
used
to
correct
the
AI
to
eliminate the
impact
of
AI
zero
offset
and
gain
.
They have been corrected upon delivery
.
When you resume the factory values
,
these
parameters
will
be
restored
to
the
factory
-
corrected
values
.
Generally
,
you
need
not
perform
correction
in
the
applications
.
Measured
voltage
indicates
the
actual
output
voltage
value
measured
by
instruments
such
as
the
multimeter
.
Displayed
voltage
indicates
the
voltage
display
value
sampled
by
the
AC
drive
.
For
details
,
refer
to
U0
-
21
,
U0
-
22
and
U0
-
23
.
During correction
,
send two voltage values to each AI terminal
,
and save the measured
values
and
displayed
values
to
the
function
codes
AC
-
00
to
AC
-
11
.
Then
the
AC
drive
will
automatically
perform
AI
zero
offset
and
gain
correction
.
If
the
input
voltage
and
the
actual
voltage
sampled
by
the
AC
drive
are
inconsistent
,
perform
correction
on
site
.
Take
AI1
as
an
example
.
The
on
-
site
correction
is
as
follows
:
1
)
Send
a
voltage
signal
(
approximately
2
V
)
to
AI1
.
2
)
Measure
the
AI1
voltage
and
save
it
to
AC
-
00
.
3
)
View
the
displayed
value
of
U0
-
21
and
save
the
value
to
AC
-
01
.
4
)
Send
a
voltage
signal
(
approximately
8
V
)
to
AI1
.
5
)
Measure
AI1
voltage
and
save
it
to
AC
-
02
.
6
)
View
the
displayed
value
of
U0
-
21
and
save
the
value
to
AC
-
03
.
At
correction
of
AI2
and
AI3
,
the
actually
sampled
voltage
is
respectively
queried
in
U0
-
22
and
U0
-
23
.
For
AI1
and
AI2
,
2
V
and
8
V
are
suggested
as
the
correction
voltages
.
For
AI3
, -
8
V
and
8
V
are
suggested
.
