2.3.3.1 Input Unit and 10 Times Input Unit
(Cent’d)
Inch/MM input is selected by setting #6001D0.
Inch/MM input selection by G20/G21 is optional.
Selection of multiplication factor xl /x10 is made
by parameter #6006D 5.
Tool offset value must always be written in O. 001
mm (or O. 0001 inch) , and offset is possible in
these units.
In O. 01 mm increment system, the following op-
eration must be made in the unit of O. 01 mm.
. Programming for operation in TAPE mode.
o Write operation in MDI mode.
o Programming for operation in MEMORY mode.
. Program editing operation in EDT mode .

If NC tape programmed by O. 001 mm is fed
into or stored in an equipment set by O. 01
mm increment, the machine will move ten
times the intended dimensions.
If the increment system is switched when the
contents of NC tape are stored in memory,
the machine will move by ten times or one
tenth of the commanded dimensions.
When the stored program is punched out on
the tape+, the stored f?gures are punched
out “as stored” regardless of switching of
the increment system.
Multiplication factor 10X (10 times the input
unit) is effective for distance command only.
It does not function on the designation of
time, angle”, etc.
When multiplication factor
10X is set as effective ( #6006D5 = 1) , the
same address word is multiplied by 10 or not
depending on type of G command.
EXAMPLE
G04 U...
;—Not multiplied by 10 (Time)
GOO U...
;— Multiplied by 10 (Distance)
2, 3. 3.2 Least Output Increment
Least output increment is the minimum unit of
tool motion. Selection of metric system or inch
system is made by parameter (#6007D3) .

2.3.4 MAXIMUM PROGRAMMABLE DIMENSIONS
Maximum programmable values of move command
are shown below .
Maximum Programmable Values
Metric input
-9999.999 mm.
Metric Output — -—
—
Inch input
-3937.0078 in
Metric input
Y99999.999 mm.
Inch Output
Inch input I
‘99999 .999 in.
In incremental programming, specified values must
not exceed the maximum programmable values. In
absolute programming, move amount of each axis
must not exceed the maximum programmable value.
THE MACHINE MAY NOT FUNCTION PROPERLY
IF MOVE COMMAND OVER THE MAXIMUM PRO-
GRAMMABLE VALUES IS GIVEN.
The above maximum programmable values also
apply to distance command addresses 1, K, R
in addition to move command addresses X , U , W .
2.3.5 ABSOLUTE AND INCREMENTAL INPUTS
Both absolute
input and incremental input can
be used for the control.
Absolute input is specified by the addresses
Xand Z.
EXAMPLE: X.. . Z.. ;
Incremental input is specified by the address-
es U and W.
EXAMPLE: U.. . W., . ;
Absolute input and incremental input can be
used in one block mixedly.
EXAMPLE: X.. . W.. ;
u.. . z. ;
Metric output

“---”-
0.0005 mm 0.001 mm
Inch output 0.00005 in. 0.0001 in.
