S1+23 Output
Manipulated
Variable %
While
the
PID
action
is
in
progress,
the
data
register
designated
by
S1+23
holds
the
manipulated
variable,
–32768
through
32767
(–327.68%
through
327.67%),
indicating
the
value
to
the
second
decimal
place.
While
manual
mode
is
enabled
with
the
auto/manual
mode
control
relay
(S2+1)
set
to
on,
S1+23
holds
an
indefinite
value.
While
auto
tuning
or
advanced
auto
tuning
is
in
progress,
S1+23
holds
an
indefinite
value.
S1+24 Output
Manipulated
Variable
for
Analog
Output
Module
While
the
PID
action
is
in
progress,
the
data
register
designated
by
S1+24
holds
a
value
of
0
through
4095
or
50000,
depending
on
the
analog
I/O
module
type.
The
value
is
converted
from
the
value
of
0
through
100
stored
in
S1+1
to
rep
‐
resent
the
output
manipulated
variable
of
0%
through
100%.
While
manual
mode
is
enabled
with
the
auto/manual
mode
control
relay
(S2+1)
set
to
on,
S1+24
holds
a
value
of
0
through
4095
or
50000
converted
from
the
manual
mode
output
manipulated
variable
(S1+18).
While
auto
tuning
or
advanced
auto
tuning
is
in
progress,
S1+24
holds
a
value
of
0
through
4095
or
50000
read
from
the
AT
output
manipulated
variable
(S1+22).
S1+25 Proportional
Band
Offset
Value
When
the
proportional
band
is
selected
(S1+4
set
to
2
or
3),
the
output
manipulated
variable
(S1+1)
of
0%
through
100%
can
be
shifted
by
an
offset
of
–100%
through
100%.
Set
a
required
offset
value
of
–100
through
100
to
the
data
register
designated
by
S1+25
before
executing
auto
tuning.
When
the
proportional
gain
is
selected
(S1+4
set
to
0
or
1),
the
proportional
band
offset
value
(S1+25)
has
no
effect.
S1+26 Derivative
Gain
The
derivative
gain
can
be
selected
from
0%
through
100%.
When
the
derivative
gain
is
set
to
a
small
value,
the
output
manipulated
variable
(S1+1)
is
susceptible
to
an
external
noise
or
a
change
in
the
set
point.
When
the
derivative
gain
is
set
to
a
large
value,
the
output
manipulated
variable
(S1+1)
becomes
less
susceptible
to
an
external
noise
or
a
change
in
the
set
point,
but
stability
is
adversely
affected
during
normal
operation.
Set
a
required
derivative
gain
of
0
through
100
to
the
data
register
designated
by
S1+26
before
executing
auto
tuning.
Recommended
values
are
20%
through
30%
when
the
process
variable
fluctuates
or
is
subject
to
noise.
