In
the
canned
cycles
of
G82, G84,
G88
and
G89,
the
dwell
is
programmed
by
the
digits
following
the
address
P,
Maximum
programmable
value:
P8388607
=
8388.607
sec.
Measurement
of
dwell
starts
at
the time
of
ter¬
mination
of
pulse
distribution
to
Z
point.
When
P
is
not
programmed
or
when the
designated
time is
zero,
the
next
operation
commences
immediately
after
termination
of
pulse
distribu¬
tion
to
Z
point.

This is
different
from

Intervention
by
manual
operation
during
canned
cycles
Note:
If
the
canned
cycles
are
executed
with
G9
0
(absolute
designation),
hole
drilling
is
repeated
in
the
same
position.
Exercise
care
in
this
respect.
In
G87
and
G89,
the
automatic
operation
is
sus¬
pended
after
spindle
stop
at
hole
bottom.
In
this
case,
select
manual
operation
mode
(JOG
or
RAPID),
and
pull
the
drill
up
from
the hole
bot¬
tom
in
the direction
of
Z
axis
by
manual
opera¬
tion.
Return
to
the
original
automatic
operation
mode
(TAPE
or
MEM)
after
ensuring
that
the
tool
is
free
from
interference,
and
start
cycle.
The
drill
returns
to
R
point
or
initial
point
and
automatic
operation
is
resumed.
This
movement
of
automatic
return
to
R
point
or
initial
point
is
not
affected
by
the
manual
ab¬
solute
switch,
and
the
drill
always
returns to
R
point
or
initial
point.
NOTES:
When
the
canned
cycles
are
executed
by
turning
on
the
SINGLE
BLOCK
switch,
a
temporary
stop
is made
in
an
intermediate
position,
and the
FEED
HOLE
lamp
lights
up.

After
termination
of
each
cycle,
if
L
com¬
mand has
been
given,
Lighting
of
this
FEED
HOLE
lamp
indicates
that
operation
is
in
the
process
of
a
cycle,
and
it
does
not
go
out
even
when
the
operation
mode
is
switched
to
manual
mode.
It
goes
out
when
a
cycle
start
is
made
in
automatic
mode.
The
single
block
stop
after
the
completion
of
canned
cycles
is
as
usual,
and
the
FEED
HOLD
lamp
does
not
light
up.
Be
sure
to
designate
R
point
and
Z
point
by
pro¬
gramming
R
and
Z
before
entering
the
canned
cycle
mode.
R
point
and
Z
point
are
cleared
when
canned
cycles
are
cancelled.

Number
of
repeat
commands
(L,
)
For
drilling
multiple
holes
at
equal
intervals,
command
can
be
given
in
one

by
program¬
ming
the
number
of
repeats
by
address
L.

The
L
command
is
non-
modal,
and is
valid
only
in
the
programmed
block.
If
L
is
not
given,
the
.operation
is
performed,
only
one
time.
