When
auto
tuning
is
not
used
by
setting
the
operation
mode
(S1+3)
to
0
(PID),
set
a
required
value
of
1
through
10000
to
specify
a
proportional
gain
of
0.01%
through
100.00%
or
a
proportional
band
of
±0.01%
through
±100.00%
to
the
data
register
designated
by
S1+7.
When
S1+7
stores
0,
the
proportional
gain
is
set
to
0.01%
or
the
proportional
band
is
set
to
±0.01%.
When
S1+7
stores
a
value
larger
than
10000,
the
proportional
gain
is
set
to
100.00%
or
the
proportional
band
is
set
to
±100.00%.
When
the
proportional
gain
is
selected,
the
output
manipulated
variable
(S1+1)
is
calculated
from
the
deviation
between
the
set
point
(S3)
and
the
process
variable
(S4).
When
the
proportional
gain
is
set
to
a
large
value,
the
proportional
band
becomes
small
and
the
response
becomes
fast,
but
overshoot
and
hunching
will
be
caused.
In
contrast,
when
the
propor
‐
tional
gain
is
set
to
a
small
value,
overshoot
and
hunching
are
suppressed,
but
response
to
disturbance
will
become
slow.
The
proportional
band
is
the
range
of
inputs
(deviation
between
the
set
point
and
the
process
variable)
required
for
the
output
manipulated
variable
(S1+1)
to
change
from
0%
to
100%.
The
output
manipulated
variable
(S1+1)
of
the
propor
‐
tional
term
is
calculated
from
the
current
input
with
respect
to
the
proportional
band.
When
the
proportional
band
is
selected,
the
integral
action
is
enabled
only
while
the
process
variable
(S1+0)
is
within
the
proportional
band,
that
is
while
the
calculated
value
for
the
output
manipulated
variable
is
between
0%
and
100%.
While
the
process
variable
(S1+0)
is
out
of
the
proportional
band,
the
integral
action
is
disabled.
While
the
PID
action
is
in
progress,
the
proportional
term
value
can
be
changed
by
the
user.
S1+8 Integral
Time
When
only
the
proportional
action
is
used,
a
certain
amount
of
difference
(offset)
between
the
set
point
(S3)
and
the
process
variable
(S1+0)
remains
after
the
control
target
has
reached
a
stable
state.
An
integral
action
is
needed
to
reduce
the
offset
to
zero.
The
integral
time
is
a
parameter
to
determine
the
amount
of
integral
action.
When
auto
tuning
or
advanced
auto
tuning
is
used
by
setting
the
operation
mode
(S1+3)
to
1
(AT+PID),
2
(AT),
3
(advanced
AT+PID),
or
4
(advanced
AT),
an
integral
time
is
determined
automatically
and
does
not
have
to
be
designated
by
the
user.
When
auto
tuning
is
not
used
by
setting
the
operation
mode
(S1+3)
to
0
(PID),
set
a
required
value
of
1
through
65535
to
specify
an
integral
time
of
0.1
sec
through
6553.5
sec
to
the
data
register
designated
by
S1+8.
When
S1+8
is
set
to
0,
the
integral
action
is
disabled.
When
the
integral
time
is
too
short,
the
integral
action
becomes
too
large,
resulting
in
hunching
of
a
long
period.
In
con
‐
trast,
when
the
integral
time
is
too
long,
it
takes
a
long
time
before
the
process
variable
(S1+0)
reaches
the
set
point
(S3).
The
integral
action
is
executed
within
the
range
between
the
plus
proportional
band
and
the
minus
proportional
band.
When
the
process
variable
(S1+0)
runs
out
of
the
proportional
band
due
to
an
external
noise
or
a
change
in
the
set
point,
the
integral
action
is
disabled.
As
a
result,
the
manipulated
variable
quickly
follows
up
the
set
point,
with
smaller
over
‐
shoot
and
undershoot.
While
the
PID
action
is
in
progress,
the
integral
time
value
can
be
changed
by
the
user.
