OPERATION
AT
LOAD
After
the
no-load
operation,
turn
off
the
AC
main
circuit
power,
and
connect
the
driven
machine
to
the
motor
.
Make
sure
that
the
driven
machine
is
in
running
condition,
and
that
proper
safety precaution
are
followed,
then
run
the
motor
under
load
in
exactly
the
same
way
as
the
test
run
.
For
preset
starting
(one-touch
operation
after setting
the
frequency)
Per-
form the
following
beforehand
:
(1)
Set the
frequency
and
depress
onTn
to
accelerate
the
motor
in
the deter-
mined
time,
as
described
earlier,
and
to
maintain
the
rpm
at
the
preset
fre-
quency
.
If
the
acceleration
time
is
set
short
relative
to
the
load
and
if
the
rpm
of
the
accelerating
motor
is
not
smooth
(anti-stalling
function
during
acceleration
is
functioning)
;
or
if
trouble
is
displayed
on
the
digital
operator,
set
the
acceleration
time
longer
.
(2)
To
decelerate
the
motor
in
the preset
time
and
to
stop
it,
depress
STOP
TT
while
the
motor
is
rotating
.
If
the
deceleration
time
is
set
short
relative to
the
load
and
if
the
rpm
of
the
decelerating
motor
is
not
smooth
(anti-stalling
function
during
deceleration
is
functioning)
;
or
if
trouble
is
displayed
on
the
digital
operator,
set
the
deceleration
time
longer
.
(1)
Start
the
motor
after
making
sure
that
the
motor
is
stopped
.
If
the operation
is
started
during
motor
coasting,
use
the
control
constant
(Cn-12)
DC
Injection
Braking
Time
at
start
in
table
5
.
(2)
When
a
standard
motor
is
driven
with
the
inverter,
there
is
a
little
increase
in
motor
temperature,
noise,
and
vibration
as
compared
to
the operation
from
the
commercial
power
sup-
ply
PRECAUTION
(3)
The
motor
cooling
effect
lowers
during
low-speed
run-
ning
.
The
torque
needs
to
be
reduced
in
accordance
with
the
frequency
.
(For the
reduction
ratio,
refer
to
the
cat-
alog
or
technical
sheet
.)
(4)
Even
with
small load,
never
use
a
motor
whose
current
exceeds
the
inverter
rating
.
(5)
When
two
or
more
motors
are
operated,
check
to
be
sure
that
the
total
motor
current
is
not
larger
than
inverter
rat-
ing
.
(6)
When
starting
and
stopping
the motor,
be
sure
to
use
the operation
signals
(FWD/REV),
not
the
magnetic
contactor
on
the
power
supply
side
.

MAINTENANCE
VS-616GII
requires
almost
no
routine
checks
.
It

if it
is
kept
clean,
cool
and
dry,
observing
precautions
listed
in

Especially
check
for tightness of
