2.1 Data Increment
2.1.1 Least Command Increment
The data increment handled in the controller includes the input setting increment and command increment.
Each type is set with parameters.
(1) The input setting increment indicates the increment handled in the internal processing of the
controller. The counter and tool compensation data, etc., input from the screen is handled with this
increment. This increment is applied per part system (1st to 4th part system, PLC axis).
(Note) The inch and metric systems cannot be used together.
(2) The command increment indicates the command increment of the movement command in the
machining program. This can be set per axis.
(Note) The inch and metric systems cannot be used together.
2.1.1.1 Least Command Increment 1 μm (Input Setting Increment 1μm)
It is possible to command 0.001mm for the linear axis and 0.001° for the rotation axis.
2.1.1.2 Least Command Increment 0.1 μm (Input Setting Increment 0.1μm)

2.2 Unit System
2.2.1 Inch/Metric Changeover
The unit systems of the data handled in the controller include the metric unit system and inch unit system.
The unit (inch/mm) for the setting and display, as well as for the handle/incremental feed can be switched
with either the parameters or machining program (G20/G21 command).
An option is required when the unit is switched with the machining program command.
(Note) For the angle data, 1.0 means 1 degree (°) regardless of the unit system.
(Note 1) The parameter changeover is valid after the power is turned ON again.
(Note 2) The unit system for the PLC axis can be switched with a parameter different from the one used with
the NC axis.
The PLC axis unit system cannot be switched with the machining program (G20/G21 command).
(Note 3) When the power is turned ON or resetting is performed, the command increment depends on the
parameter setting.
2.2.2 Input Command Increment Tenfold
The program's command increment can be multiplied by an arbitrary scale with the parameter designation.
This function is valid when a decimal point is not used for the command increment.
For example, this function allows a CNC unit, for which the command increment is set to 1μm, to run a
machining program, which has been created with a 10μm input command increment, as same as before.
The scale is set with the parameters.
(Note 1) This function cannot be used for the dwell function G04_X_(P_);.
(Note 2) This function cannot be used for the compensation amount of the tool offset input.
(Note 3) This function can be used when decimal point type I is valid, but cannot be used when decimal
point type II is valid.

2.4 Command Value
2.4.1 Decimal Point Input I, II
There are two types of the decimal point input commands and they can be selected by parameter.
(1) Decimal point input type I
When axis coordinates and other data are issued in machining program commands, the assignment of
the program data can be simplified by using a decimal point. The minimum digit of a command not using
a decimal point is the same as the least command increment.
The decimal point can be applied not only to axis coordinate position but also to speed commands and
dwell commands.
The decimal point position serves as the millimeter unit in the metric mode, as the inch unit in the inch
mode and as the second unit in a time designation of dwell command.
(2) Decimal point input type II
As opposed to type I, the minimum digit of a command without a decimal point serves as the millimeter
unit in the metric mode, as the inch unit in the inch mode and as the second unit in the time designation.
The "." (point) must be added when commands below the decimal point are required.
(*1) The F unit is mm/min for either type (inch system : inch/min).

2.4.2 Absolute/Incremental Command
(1) M system
When axis coordinate data is issued in a machining program command, either the incremental
command method (G91) that commands a relative distance from the current position or the absolute
command method (G90) that moves to a designated position in a predetermined coordinate system can
be selected.
The absolute and incremental commands can be both used in one block, and are switched with G90 or
G91. However, the arc radius designation (R) and arc center designation (I, J, K) always use
incremental designations.
G90 ... Absolute command (absolute command)
G91 ... Incremental command (incremental command)
These G codes can be commanded multiple times in one block.
Example
(Note 1) As with the memory command, if there is no G90/G91 designation in the MDI command,
the previously executed modal will be followed.

2.4.3 Diameter/Radius Designation
For axis command value, the radius designation or diameter designation can be changed over with
parameters.
When the diameter designation is selected, the scale of the length of the selected axis is doubled.
(Only the half (1/2) of the commanded amount moves.)
This function is used when programming the workpiece dimensions on a lathe as diameters.
Changing over from the diameter designation to the radius designation or vice versa can be set separately

3.1 Positioning
3.1.1 Positioning
This function carries out high-speed positioning following the movement command given in a program.
The above command positions the tool with rapid traverse rate. The tool path takes the shortest distance to
the end point in the form of a straight line.
For details on the rapid traverse feed rate of the NC, refer to the section entitled "Rapid Traverse Rate".
Since the actual rapid traverse feed rate depends on the machine, refer to the specifications of the machine
concerned.
(1) The rapid traverse feed rate can be set for each axis with parameters.
(2) The number of axes which can be commanded simultaneously depends on the specifications (number
of simultaneously controlled axes). The axes can be used in any combination within this range.
(3) The feed rate is controlled within the range that it does not exceed the rapid traverse rate of each axis
and so that the shortest time is taken. (Linear type)
Parameter setting enables movement at the rapid traverse rates of the respective axes independently
for each axis. In this case, the tool path does not take the form of a straight line to the end point. (Non-
Linear type)
(4) The tool is always accelerated at the start of the program command block and decelerated at the end of
the block.
