(H,

CODES)
NOTES:
Two
digits,
following
the
address
H
or
D,
specify
tool
offset
numbers.
•
The
addresses
H
and
D
used
to
designate
tool
offset
numbers
are
equivalent
in
all
respects.
When
H
(or D)
is
given,
the
system
interprets
that
D
(or
H)
is also
given.
•
However,
programmers
may
conveniently
dis¬
tinguish
H
from
D,
thus:

• •
For

Furthermore,
more
conveniently
for
program¬
ming,

may
also
be
distinguished
as

The
tool
offset
numbers
01
through
99
directly
correspond
to
the
99
offset-value
memory
num¬
bers.
That
is,
when certain
numbers
are
des¬
ignated,,
the
corresponding
offset
values stored
in
the
offset
memories
will
be
used
to
offset
the
tools
.

Tool

numbers

differ¬
ent
meanings depending
on
the
respective
offset
functions.
