Suppressing
Short
Cycle
Vibration
If
vibration
occurs
when
the
vibration
cycle
is
short,
and
the
cycle
is
almost
identical
to
the
derivative
time
(D)
set
value,
the
differential
operation
is
too
strong.
Shorten
the
derivative
time
(D)
to
suppress
the
vibration.
If
vibration
continues
even
when
the
derivative
time
(D)
is
set
to
0.00
(D
control
disabled),
reduce
the
propor-
tional
gain
(P),
or
increase
the
PID
primary
delay
time
constant.
nSetting
Precautions
• In
PID
control,
the
b5-04
parameter
is
used
to
prevent
the
calculated
integral
control
value
from
exceeding
a
specified
amount.
When
the
load
varies
rapidly,
Inverter
response
is
delayed,
and
the
machine
may
be
damaged
or
the
motor
may
stall.
In
this
case,
reduce
the
set
value
to
speed
up
Inverter
response.
• The
b5-06
parameter
is
used
to
prevent
the
arithmetic
operation
following
the
PID
control
calculation
from
exceeding
a
specified
amount.
Set
taking
the
maximum
output
frequency
to
be
100%.
• The
b5-07
parameter
is
used
to
adjust
PID
control
offset.
Set
in
increments
of
0.1%,
taking
the
maximum
output
frequency
to
be
100%.
• Set
the
low
pass
filter
time
constant
for
the
PID
control
output
in
b5-08.
Enable
this
parameter
to
prevent
machinery
resonance
from
occurring
when
machinery
adhesive
abrasion
is
great,
or
rigidity
is
poor.
In
this
case,
set
the
constant
to
be
greater
than
the
resonance
frequency
cycle.
Increase
this
time
constant
to
reduce
Inverter
responsiveness.
• Using
b5-09,
you
can
invert
the
PID
output
polarity.
Consequently,
if
you
increase
the
PID
target
value,
you
can
apply
this
parameter
to
applications
to
lower
the
Inverter
output
frequency.
• Using
b5-10,
you
can
apply
gain
to
the
PID
control
output.
Enable
this
parameter
to
adjust
the
amount
of
compensation
if
adding
PID
control
output
to
the
frequency
reference
as
compensation.
• When
the
PID
control
output
is
negative,
the
output
direction
can
be
reversed
by
the
parameter
b5-11.
However,
PID
control
output
is
limited
to
0
when
b1-04
(Prohibition
of
reverse
operation)
is
set
to
1
(enabled).
• With
the
Inverter,
by
setting
an
independent
acceleration/deceleration
time
in
parameter
b5-17,
you
can
increase
or
decrease
the
PID
target
value
using
the
acceleration/deceleration
time.
The
acceleration/
deceleration
function
(C1
parameters)
used
normally,
however,
is
allocated
after
PID
control,
so
depending
on
the
settings,
resonance
with
PID
control
and
hunting
in
the
machinery
may
occur.
If
this
happens,
reduce
C1
parameters
until
hunting
does
not
occur,
and
maintain
the
acceleration/deceleration
time
using
b5-17.
Also,
you
can
disable
the
set
value
in
b5-17
from
the
external
terminals
during
operation
using
multi-function
input
set
value
34
(PID
soft
starter).
