Handling
of
Decimal Point Input
:

Decimal
point
input
With the control equipped with the
CRT
char¬
acter
display,
a number
having a decimal
point
can be
input.
'
Shown below
is the address data
capable of
using
a decimal
point
and the position of
a
decimal
point.
NOTES:
•
The
trailing zeros
(zeros
to
be
suffixed)
can be
omitted by use of
decimal
point.
Sufficient
attention
should
be
given,
as
it
causes
great
mistake, so
far as
the data concerns, if
a de¬
cimal point happens
to
be keyed m or
not
by
mistake.
When keying
in a decimal
point
data by
MDI
writing operation, the trailing zeros will be
suffixed corresponding
to
the least'Input
in¬
crement
currently
designated,
and displayed on
the CRT display.
While, with
the
writing operation
for editing,
no
trailing zeros will
be
displayed, and the
decimal
point data
will
be stored
into
the
mem¬
ory as it has
been
keyed
in-
During
the
MEM
operation,
the
trailing zeros will be
properly
by processed throughout
the
operation.

NOTE- A
distance unit
as
currently designated
by
a parameter
is effective. A decimal
point
data
will
be
handled
in
terms
of
a feedrate
unit
which becomes effective
by
means
of
a designa¬
tion
of
G98 or G99.
• Combination of the
decimal
point data and the
no
decimal
point data can be made.
Example:
X123.4 Z 1000
x
•
Whenever a
number
containing
the numerals
smaller
than
the least
input
increment
is in¬
structed,
the
numerals smaller than
the
least
input
increment
designated will be disregarded.

Be
sure never
to
use a
decimal
point
to
all
address
data such
as
M, S and T codes,
except
for the
ones specified. Generally, it will be
disregarded, however, concurrence may
not
be
made
during an address search operation.
