The

operation
is
allowed
only
when the
message
“READY’
is
displayed
with
the
ATC
sequence
number
set
at

This
automatically
carries
out
one
complete
automatic tool

When
it
is
necessary
to
change
the

of

is
possible
from
any
ATC
operation
sequence
number.
The
operations
activated
by
the
pressing
of
the

key
depend
on
the

sequence
where
it
is
pressed.
That
is,
when

is
pressed
before
the
tool
change
arm
1
80
degree
rotation,
the

occurs.
However,
when
the RETURN
CYCLE
START
key
is
pressed
after
the tool
change
arm
1
80
degree
rotation
sequence,
then the
automatic
tool
change
cycle
is
continued.

ATC
operations
advance
one
step
at
a
time.
When
the
cycle
does
not
advance
even
if
this
key
is
pressed,
due

press
the
I

while
pressing
the

It
will
then
ignore
them and
continue
operations.
This
key
is
inoperative
while the
message
“RUN”
is
being
displayed
on
the
display
screen even
if
the
ATC

not
operating.
In
this
case,
clear the
“RUN”
message
from
the
screen
by
resetting,
before
pressing
the
1
STEP
ADVANCE
key.
Note
that
when
mechanical
conditions
are
not
met,
the
1
STEP
ADVANCE
key
is
not
operative
even
when
the
INTERLOCK
RELEASE
key
is
pressed
since
these
conditions
are
not
ignored.
The
message
“RUN"
remains
on
the
display
screen.
(f)
1
STEP

This
returns
the
ATC
operations
one
step
each
time
it
is
pressed.
Functions
of
the
1
STEP
RETURN
key
are
the
same as
the
1

ADVANCE
key
except
that
the
ATC
operations
are
returned
instead
of
advanced.
