It
decides
the
regulating

of
the
PID
regulator
.
The
higher
the
Kp1
is
,
the
larger
the
regulating
intensity
is
.
The

(
Integral

It
decides
the integral
regulating
intensity
.
The shorter the
integral time is
,
the
larger
the
regulating
intensity
is
.
When
the
deviation
between
PID
feedback
and
PID
setting
is
100
.
0
%,
the
integral
regulator
performs
continuous
adjustment
for
the

set
in
PA

Then
the
adjustment

reaches
the

.
•
PA

07
(
Differential
time
Td1
)
It decides the regulating intensity of the PID regulator on the deviation change
.
The
longer
the
differential
time
is
,
the
larger
the
regulating
intensity
is
.
Differential time is the
time
within
which
the
feedback
value
change
reaches
100
.
0
%,
and
then
the
adjustment
amplitude
reaches
the
maximum
frequency

In some situations
,
only when the PID output frequency is a negative value
(
AC drive
reverse rotation
),
PID
setting
and
PID feedback
can
be equal
.
However
,
too
high reverse

frequency
is prohibited
in some applications
,
and PA

used to determine the

It is
used
to set the
PID
differential output range
.
In
PID control
,
the
differential operation
may
easily
cause
system
oscillation
.
Thus
,
the
PID
differential regulation
is
restricted
to
a
small
range
.

The PID setting changes linearly according to the change time
