WARNING
CAUTION
Note that even items ranked as " CAUTION", may lead to major results depending on the situation.
In any case, important information that must always be observed is described.
Not applicable in this manual.
When there is a great risk that the user could be subject to
fatalities or serious injuries if handling is mistaken.
When the user could be subject to fatalities or serious injuries
if handling is mistaken.
When the user could be subject to injuries or when physical
damage could occur if handling is mistaken.
DANGER
Not applicable in this manual.
1. Items related to product and manual
The items that are not described in this manual must be interpreted as "not possible".
This manual is written on the assumption that all option functions are added.
Some functions may differ or some functions may not be usable depending on the NC
system (software) version.
2. Items related to start up and maintenance
Follow the power specifications (input voltage range, frequency range, momentary
power failure time range) described in this manual.
Follow the environment conditions (ambient temperature, humidity, vibration,
atmosphere) described in this manual.
!
Follow the remote type machine contact input/output interface described in this manual.
(Connect a diode in parallel with the inductive load or connect a protective resistor in
serial with the capacitive load, etc.)
WARNING
CAUTION
If the parameter is used to set the temperature rise detection function to invalid,
overheating may occur, thereby disabling control and possibly resulting in the axes
running out of control, which in turn may result in machine damage and/or bodily injury
or destruction of the unit. It is for this reason that the detection function is normally left
"valid" for operation.
The parameter for the temperature rise detection function will be validated forcibly
when the NC unit is turned ON.

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 command s and
dwell commands.
The decimal point position serves as the millimetre 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 millimetre
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.

When a simultaneous 4-axis command is used with
the V axis as the axis parallel to the Y axis, helical

This function interpolates arcs where the start point and endpoint are not on the circumference of the same
circle into spiral shapes.
There are two types of command formats which can be changed with the parameters.
(1) For command format type 1

Xx1, Yy1 : End point coordinate
Ii1, Jj1 : Arc center
Pp1 : Number of pitches
Ff1 : Feed rate
The circular interpolation operation is performed at the feed rate f1 by the commands listed above. The tool
draws a spiral arc path whose center is at the position from the start point which is designated by distance i1
for the X-axis direction and distance j1 for the Y-axis direction as the tool moves toward the end point.
The arc plane is designated by G17, G18 or G19.
G17: XY plane
G18: ZX plane
G19: YZ plane
The direction of the arc rotation is designated by G02.1 or G03.1.
G02.1: Clockwise (CW)
G03.1: Counterclockwise (CCW)
The number of pitches (number of rotations) is designated by p1.
By assigning zero to p1, the pitch designation can be omitted in this case, the interpolation is obtained as a
spiral rotation of less than one full turn. Assigning 1 to p1 yields a spiral rotation of more than one full turn
but less than two full turns.

This function transfers the shape that is on the cylinder's side surface (shape yielded by the cylindrical
coordinate system) onto a plane, and when the transferred shape is designated in the program in the form of
plane coordinates, the shape is converted into a movement along the linear and rotary axes of the original
cylinder coordinates, and the contours are controlled by means of the CNC unit during machining.
Since the programming can be performed for the shapes produced by transferring the side surfaces of the

When a lathe with linear axes (X, Z axes) and rotary axis (C axis) serving as the control axes is to perform
milling at a workpiece end face or in the longitudinal direction of the workpiece, this function uses the
hypothetical axis Y which is at right angles to both the X and Z axes to enables the milling shape to be
programmed as the X, Y and Z orthogonal coordinate system commands.
With this function, the workpiece can be treated as a cylinder with radius X, and commands can be
designated on the plane formed by transferring the cylinder side surface instead. With milling interpolation,
the commands programmed by the orthogonal coordinate system are converted into linear axis and rotary
axis movements (workpiece rotation) to control the contours.

This function automatically generates spline curves that smoothly pass through rows of dots designated by a

This function realizes NURBS curve machining by commanding NURBS curve parameters (number of sta ges,
weight, knot, control point). The path does not need to be replaced with fine segments.
This function operates only in the high-speed high-accuracy contro l 2 mode, so the hig h-speed high-a ccuracy
control 2 option is required.
During NURBS interpolation, interpolation takes place at the commanded speed. However, if the cu rvature is
large, the speed is clamped so that the machine's tolerable acceleration rate is not exceeded.
NURBS interpolation cannot be used during graphic check (continuous/step check).
Linear interpolation that connects the control points is used during graphic check.

To issue a circular command over a three-dimensional space, an arbitrary point (intermediate point) must be
designated on the arc in addition to the start point (current position) and end point. Using the 3-dimensional
circular interpolation command, an arc shape determined by the three points (start point, intermediate point,
end point) designated on the three-dimensional space can be machined.

•
The operation is the same for G02.4 and G03.4. (The rotation direction cannot be design ated.)
•
The axes used as the reference in 3-dimensional circular interpolation are the three basic axes set
with the parameters.
•
The X, Y, Z address in the block may be omitted. The intermediate point coordinates omitted in the 1st
block become the start point coordinates, and the end point coordinates omitted in the 2nd block
become the intermediate point coordinates.
•
When using the 3-dimensional circular interpolation command, an arbitrary axis can be commande d
in addition to the orthogonal coordinate system (X, Y, Z) used as the reference. The arbitrary axis
designated in the intermediate point designating block (1st block) will interpolate to the comm and
point when moving from the start point to intermediate point movement. The arbitrary axis designated
in the end point command block (2nd block) will interpolate to the command point when moving from
the intermediate point to the end point. The number of arbitrary axes that can be command ed differs
according to the number of simultaneous contour control axes. The total of the basic three axes used
as the reference of the 3-dimensional circular interpolation and the arbitrary axes commanded
simultaneously must be less than the number of simultaneous contour control axes.

Automatic operation
Cutting feed rate For the inch system, the rotary axis command speed is multiplied by 10.
For example, if the B axis is the rotary axis in the inch system and the following
type of machining program is executed, the rotary axis command speed will be
multiplied by 10, and the rotary axis will move at 1000 deg./min.
N1 G1 B100. F100.;
Rapid traverse rate The rapid traverse rate is not multiplied by 10, and is the speed set in the
parameters.
Manual operation The command speeds related to manual operation, such as JOG feed, are not
multiplied by 10. The display speed unit also remains as "deg./min".

During inside cutting when machining curved shapes with tool radius compensation applied, the machining
speed on the cutting surface becomes faster than the tool center feedrate. Therefore, problems such as
reduced accuracy on the cutting surface may occur.
This reduced accuracy can be prevented with inverse time feed. This function can, in place of normal feed
commands, issue one block of machining time (inverse) in F co m mand s. The machi ning sp eed on the cu tting
surface is constantly controlled, even if radius compensation is applied to the machining program that
expresses the free curve surface with fine segment lines.
Note that when the calculated machining time exceeds the cutting feed clamp speed, the F com mand value in
the inverse time feed follows the cutting feed clamp speed.

The feed rate registered by parameter can be assigned by designating a single digit following address F.
There are six F codes: F0 and F1 to F5. The rapid traverse rate is applied when F0 is issued which is the
same as the G00 command. When one of the codes F1 to F5 is issued, the cutt ing feedrate set to support the
code serves as the valid rate command. If F6 or larger value is command, the value is regarded as the cutting
feedrate which has been directly commanded with numerical values.
When an F 1-digit command has been issued, the external output signal is output.
When the programmed feed rate has been issued as an F 1-digit command, the feed rate can be increased or
reduced by turning the manual handle.
The feed rate cannot be changed by the 2nd and 3rd handles.
(1) Amount by which speed is varied by manual handle
Speed variation amount ΔF is expressed by the equation below:
ΔF = ΔP ×
FM
K
ΔP : Handle pulses (±)
FM : F1 to F5 upper limit (parameter setting)
K : Speed variation constant (parameter setting)
(Example) When the feed rate is to be increased or reduced by 10 mm/min per manual handle scale
increment
If FM is 3600 mm/min, then:
ΔF = 10 = 1 ×
3600
K
Therefore, K = 360.
(2) Conditions under which F1-digit feed is valid
(a) The automatic operation must be selected.
(b) Automatic start must be underway.
(c) Cutting feed must be underway, and the F 1-digit feed rate must be designated.
(d) The F 1-digit valid parameter must be ON.

This function performs acceleration and deceleration at a constant inclination during linear acceleration/

acceleration (deceleration) times determined for each axis by the rapid traverse rate of commands executed
simultaneously, the rapid traverse acceleration and deceleration time constant, and the interpolation distance,

This function carries out the acceleration/deceleration according to the torque characteristic of the motor in
the rapid traverse mode during automatic operation. (This function is not available in manual operation.) The
rapid traverse constant inclination multi-step acceleration/deceleration method make s for improved cycle time
because the positioning time is shortened by using the motor ability to its maximum.
In general, the servomotor has the characteristic that the torque falls in the high-speed rotation range.

In the rapid traverse constant inclination acceleration/deceleration method, the acceleration has been treated
constantly because this torque characteristic is not considered. So, It is necessary to use a minimum
acceleration within the used speed range. Therefore, the margin of acceleration must be had in a low-speed
range. Or if the acceleration is used to its maximum, the upper limit of the rotation speed must be slowed.
Then, to use the servomotor ability to its maximum, acceleration/deceleration to which the torque
characteristic is considered is carried out by the rapid traverse constant inclination multi-step
acceleration/deceleration method.

"Manual feedrate B" is a function that sets an arbitrary axis feedrate from the user PLC separately from the
"manual feedrate". The "manual feedrate B" feedrate setting can be selected from the feedrate common for
all axes and the feedrate independent of reach axis. By combining the "manual feedrate B" function with the
manual/automatic simultaneous function, an arbitrary axis can be moved at the "manual feedrate B"
independently of the machining program operation even during automatic o peration. Similarly, if the jog mode
and other manual operation mode are set simultaneously, an arbitrary axis can be moved at a speed
independent from the "manual feedrate" even during the manual operation mode.
The "manual feedrate B" function can move an axis at a speed different from the "manual feedrate". This is
not affected by dry run, or by manual or cutting override, so an arbitrary axis can be moved independently
even in operations during automatic operation or override during manual axis movement.
The relation of the "manual feedrate B" and "manual feedrate" is shown below.

When using the manual feed rate B function and machining by moving the orthogonal axis while rotating the
rotary table, the tool nose and workpiece's relative speed will drop as the tool nears the rotation center if the
table rotation speed remains under the set conditions. This function controls the table rotation speed
according to the distance from the rotation center.
As shown below, the distance (radius) from the rotation center at t wo points and the rota ry axis speed at each
point is set in the parameters. When the "manual feed rate B constant surface speed control valid" signal is

The spindle rotation speed is determined in consideration of the override and gear ratio for the S command
commanded in automatic operation or with manual numerical commands, and the spindle is rotated. The
following diagram shows an outline of the spindle control.
When an 8-digit number following address S (S0 to S±99999999) is commanded, a signed 32-bit binary data
and start signal, or a non-signed 32-bit binary data and start signal will be output to the PLC.
Up to 1 set of S commands can be commanded in one block.
Processing and complete sequences must be incorporated on the PLC side for all S commands.
