SAFETY PRECAUTIONS B-63944EN-1/04
GENERAL WARNINGS AND CAUTIONS
WARNING
1 Never attempt to machine a workpiece without first checking the operation of the
machine. Before starting a production run, ensure that the machine is operating
correctly by performing a trial run using, for example, the single block, feedrate
override, or machine lock function or by operating the machine with neither a tool
nor workpiece mounted. Failure to confirm the correct operation of the machine
may result in the machine behaving unexpectedly, possibly causing damage to
the workpiece and/or machine itself, or injury to the user.
2 Before operating the machine, thoroughly check the entered data.
Operating the machine with incorrectly specified data may result in the machine
behaving unexpectedly, possibly causing damage to the workpiece and/or
machine itself, or injury to the user.
3 Ensure that the specified feedrate is appropriate for the intended operation.
Generally, for each machine, there is a maximum allowable feedrate.
The appropriate feedrate varies with the intended operation. Refer to the manual
provided with the machine to determine the maximum allowable feedrate.
If a machine is run at other than the correct speed, it may behave unexpectedly,
possibly causing damage to the workpiece and/or machine itself, or injury to the
user.
4 When using a tool compensation function, thoroughly check the direction and
amount of compensation.
Operating the machine with incorrectly specified data may result in the machine
behaving unexpectedly, possibly causing damage to the workpiece and/or
machine itself, or injury to the user.
5 The parameters for the CNC and PMC are factory-set. Usually, there is not need
to change them. When, however, there is not alternative other than to change a
parameter, ensure that you fully understand the function of the parameter before
making any change.
Failure to set a parameter correctly may result in the machine behaving
unexpectedly, possibly causing damage to the workpiece and/or machine itself,
or injury to the user.
6 Immediately after switching on the power, do not touch any of the keys on the
MDI panel until the position display or alarm screen appears on the CNC unit.
Some of the keys on the MDI panel are dedicated to maintenance or other
special operations. Pressing any of these keys may place the CNC unit in other
than its normal state. Starting the machine in this state may cause it to behave
unexpectedly.
7 The OPERATOR’S MANUAL and programming manual supplied with a CNC
unit provide an overall description of the machine's functions, including any
optional functions. Note that the optional functions will vary from one machine
model to another. Therefore, some functions described in the manuals may not
actually be available for a particular model. Check the specification of the
machine if in doubt.
8 Some functions may have been implemented at the request of the machine-tool
builder. When using such functions, refer to the manual supplied by the
machine-tool builder for details of their use and any related cautions.

B-63944EN-1/04 SAFETY PRECAUTIONS
CAUTION
The liquid-crystal display is manufactured with very precise fabrication
technology. Some pixels may not be turned on or may remain on. This
phenomenon is a common attribute of LCDs and is not a defect.
NOTE
Programs, parameters, and macro variables are stored in nonvolatile memory in
the CNC unit. Usually, they are retained even if the power is turned off.
Such data may be deleted inadvertently, however, or it may prove necessary to
delete all data from nonvolatile memory as part of error recovery.
To guard against the occurrence of the above, and assure quick restoration of
deleted data, backup all vital data, and keep the backup copy in a safe place.
WARNINGS AND CAUTIONS RELATED TO PROGRAMMING
This section covers the major safety precautions related to programming. Before attempting to perform
programming, read the supplied OPERATOR’S MANUAL carefully such that you are fully familiar with
their contents.
WARNING
1
Coordinate system setting
If a coordinate system is established incorrectly, the machine may behave
unexpectedly as a result of the program issuing an otherwise valid move
command. Such an unexpected operation may damage the tool, the machine
itself, the workpiece, or cause injury to the user.
2
Positioning by nonlinear interpolation
When performing positioning by nonlinear interpolation (positioning by nonlinear
movement between the start and end points), the tool path must be carefully
confirmed before performing programming. Positioning involves rapid traverse. If
the tool collides with the workpiece, it may damage the tool, the machine itself,
the workpiece, or cause injury to the user.
3
Function involving a rotation axis
When programming polar coordinate interpolation or normal-direction
(perpendicular) control, pay careful attention to the speed of the rotation axis.
Incorrect programming may result in the rotation axis speed becoming
excessively high, such that centrifugal force causes the chuck to lose its grip on
the workpiece if the latter is not mounted securely. Such mishap is likely to
damage the tool, the machine itself, the workpiece, or cause injury to the user.
4
Inch/metric conversion
Switching between inch and metric inputs does not convert the measurement
units of data such as the workpiece origin offset, parameter, and current
position. Before starting the machine, therefore, determine which measurement
units are being used. Attempting to perform an operation with invalid data
specified may damage the tool, the machine itself, the workpiece, or cause injury
to the user.
s-3
SAFETY PRECAUTIONS B-63944EN-1/04
WARNING
5
Constant surface speed control
When an axis subject to constant surface speed control approaches the origin of
the workpiece coordinate system, the spindle speed may become excessively
high. Therefore, it is necessary to specify a maximum allowable speed.
Specifying the maximum allowable speed incorrectly may damage the tool, the
machine itself, the workpiece, or cause injury to the user.
6
Stroke check
After switching on the power, perform a manual reference position return as
required. Stroke check is not possible before manual reference position return is
performed. Note that when stroke check is disabled, an alarm is not issued even
if a stroke limit is exceeded, possibly damaging the tool, the machine itself, the
workpiece, or causing injury to the user.
7
Tool post interference check
A tool post interference check is performed based on the tool data specified
during automatic operation. If the tool specification does not match the tool
actually being used, the interference check cannot be made correctly, possibly
damaging the tool or the machine itself, or causing injury to the user. After
switching on the power, or after selecting a tool post manually, always start
automatic operation and specify the tool number of the tool to be used.
8
Absolute/incremental mode
If a program created with absolute values is run in incremental mode, or vice
versa, the machine may behave unexpectedly.
9
Plane selection
If an incorrect plane is specified for circular interpolation, helical interpolation, or
a canned cycle, the machine may behave unexpectedly. Refer to the
descriptions of the respective functions for details.
10
Torque limit skip
Before attempting a torque limit skip, apply the torque limit. If a torque limit skip
is specified without the torque limit actually being applied, a move command will
be executed without performing a skip.
11
Programmable mirror image
Note that programmed operations vary considerably when a programmable
mirror image is enabled.
12
Compensation function
If a command based on the machine coordinate system or a reference position
return command is issued in compensation function mode, compensation is
temporarily canceled, resulting in the unexpected behavior of the machine.
Before issuing any of the above commands, therefore, always cancel
compensation function mode.
s-4
B-63944EN-1/04 SAFETY PRECAUTIONS
WARNINGS AND CAUTIONS RELATED TO HANDLING
This section presents safety precautions related to the handling of machine tools. Before attempting to
operate your machine, read the supplied OPERATOR’S MANUAL carefully, such that you are fully
familiar with their contents.
WARNING
1
Manual operation
When operating the machine manually, determine the current position of the tool
and workpiece, and ensure that the movement axis, direction, and feedrate have
been specified correctly. Incorrect operation of the machine may damage the
tool, the machine itself, the workpiece, or cause injury to the operator.
2
Manual reference position return
After switching on the power, perform manual reference position return as
required.
If the machine is operated without first performing manual reference position
return, it may behave unexpectedly. Stroke check is not possible before manual
reference position return is performed.
An unexpected operation of the machine may damage the tool, the machine
itself, the workpiece, or cause injury to the user.
3
Manual numeric command
When issuing a manual numeric command, determine the current position of the
tool and workpiece, and ensure that the movement axis, direction, and command
have been specified correctly, and that the entered values are valid.
Attempting to operate the machine with an invalid command specified may
damage the tool, the machine itself, the workpiece, or cause injury to the
operator.
4
Manual handle feed
In manual handle feed, rotating the handle with a large scale factor, such as 100,
applied causes the tool and table to move rapidly. Careless handling may
damage the tool and/or machine, or cause injury to the user.
5
Disabled override
If override is disabled (according to the specification in a macro variable) during
threading, rigid tapping, or other tapping, the speed cannot be predicted,
possibly damaging the tool, the machine itself, the workpiece, or causing injury
to the operator.
6
Origin/preset operation
Basically, never attempt an origin/preset operation when the machine is
operating under the control of a program. Otherwise, the machine may behave
unexpectedly, possibly damaging the tool, the machine itself, the tool, or causing
injury to the user.
7
Workpiece coordinate system shift
Manual intervention, machine lock, or mirror imaging may shift the workpiece
coordinate system. Before attempting to operate the machine under the control
of a program, confirm the coordinate system carefully.
If the machine is operated under the control of a program without making
allowances for any shift in the workpiece coordinate system, the machine may
behave unexpectedly, possibly damaging the tool, the machine itself, the
workpiece, or causing injury to the operator.
s-5
SAFETY PRECAUTIONS B-63944EN-1/04
WARNING
8
Software operator's panel and menu switches
Using the software operator's panel and menu switches, in combination with the
MDI panel, it is possible to specify operations not supported by the machine
operator's panel, such as mode change, override value change, and jog feed
commands.
Note, however, that if the MDI panel keys are operated inadvertently, the
machine may behave unexpectedly, possibly damaging the tool, the machine
itself, the workpiece, or causing injury to the user.
9
RESET key
Pressing the RESET key stops the currently running program. As a result, the
servo axes are stopped. However, the RESET key may fail to function for
reasons such as an MDI panel problem. So, when the motors must be stopped,
use the emergency stop button instead of the RESET key to ensure security.
10
Manual intervention
If manual intervention is performed during programmed operation of the
machine, the tool path may vary when the machine is restarted. Before restarting
the machine after manual intervention, therefore, confirm the settings of the
manual absolute switches, parameters, and absolute/incremental command
mode.
11
Feed hold, override, and single block
The feed hold, feedrate override, and single block functions can be disabled
using custom macro system variable #3004. Be careful when operating the
machine in this case.
12
Dry run
Usually, a dry run is used to confirm the operation of the machine. During a dry
run, the machine operates at dry run speed, which differs from the
corresponding programmed feedrate. Note that the dry run speed may
sometimes be higher than the programmed feed rate.
13
Cutter and tool nose radius compensation in MDI mode
Pay careful attention to a tool path specified by a command in MDI mode,
because cutter or tool nose radius compensation is not applied. When a
command is entered from the MDI to interrupt in automatic operation in cutter or
tool nose radius compensation mode, pay particular attention to the tool path
when automatic operation is subsequently resumed. Refer to the descriptions of
the corresponding functions for details.
14
Program editing
If the machine is stopped, after which the machining program is edited
(modification, insertion, or deletion), the machine may behave unexpectedly if
machining is resumed under the control of that program. Basically, do not
modify, insert, or delete commands from a machining program while it is in use.

B-63944EN-1/04 SAFETY PRECAUTIONS
WARNINGS RELATED TO DAILY MAINTENANCE
WARNING
1
Memory backup battery replacement
When replacing the memory backup batteries, keep the power to the machine
(CNC) turned on, and apply an emergency stop to the machine. Because this
work is performed with the power on and the cabinet open, only those personnel
who have received approved safety and maintenance training may perform this
work.
When replacing the batteries, be careful not to touch the high-voltage circuits
(marked and fitted with an insulating cover).
Touching the uncovered high-voltage circuits presents an extremely dangerous
electric shock hazard.
NOTE
The CNC uses batteries to preserve the contents of its memory, because it must
retain data such as programs, offsets, and parameters even while external
power is not applied.
If the battery voltage drops, a low battery voltage alarm is displayed on the
machine operator's panel or screen.
When a low battery voltage alarm is displayed, replace the batteries within a
week. Otherwise, the contents of the CNC's memory will be lost.
Refer to the Section “Method of replacing battery” in the OPERATOR’S
MANUAL (Common to T/M series) for details of the battery replacement
procedure.
WARNING
2
Absolute pulse coder battery replacement
When replacing the memory backup batteries, keep the power to the machine
(CNC) turned on, and apply an emergency stop to the machine. Because this
work is performed with the power on and the cabinet open, only those personnel
who have received approved safety and maintenance training may perform this
work.
When replacing the batteries, be careful not to touch the high-voltage circuits
(marked
and fitted with an insulating cover).
Touching the uncovered high-voltage circuits presents an extremely dangerous
electric shock hazard.
NOTE
The absolute pulse coder uses batteries to preserve its absolute position.
If the battery voltage drops, a low battery voltage alarm is displayed on the
machine operator's panel or screen.
When a low battery voltage alarm is displayed, replace the batteries within a
week. Otherwise, the absolute position data held by the pulse coder will be lost.

1.1 NOTES ON READING THIS MANUAL
CAUTION
1 The function of an CNC machine tool system depends not only on the CNC, but on
the combination of the machine tool, its magnetic cabinet, the servo system, the
CNC, the operator's panels, etc. It is too difficult to describe the function,
programming, and operation relating to all combinations. This manual generally
describes these from the stand-point of the CNC. So, for details on a particular
CNC machine tool, refer to the manual issued by the machine tool builder, which
should take precedence over this manual.
2 In the header field of each page of this manual, a chapter title is indicated so that
the reader can reference necessary information easily.
By finding a desired title first, the reader can reference necessary parts only.
3 This manual describes as many reasonable variations in equipment usage as
possible. It cannot address every combination of features, options and commands
that should not be attempted.
If a particular combination of operations is not described, it should not be
attempted.

1.GENERAL GENERAL B-63944EN-1/04
1.2 NOTES ON VARIOUS KINDS OF DATA
CAUTION
Machining programs, parameters, offset data, etc. are stored in the CNC unit
internal non-volatile memory. In general, these contents are not lost by the
switching ON/OFF of the power. However, it is possible that a state can occur
where precious data stored in the non-volatile memory has to be deleted,
because of deletions from a maloperation, or by a failure restoration. In order to
restore rapidly when this kind of mishap occurs, it is recommended that you
create a copy of the various kinds of data beforehand.

1.1 OFFSET................................................................................................................................................9
1.1 OFFSET
Explanation
- Tool offset
Usually, several tools are used for machining one workpiece. The tools have different tool length. It is
very troublesome to change the program in accordance with the tools.
Therefore, the length of each tool used should be measured in advance. By setting the difference between
the length of the standard tool and the length of each tool in the CNC (see “Setting and Displaying Data”
in the OPERATOR’S MANUAL (Common to Lathe System/Machining Center System)), machining can
be performed without altering the program even when the tool is changed. This function is called tool
offset.

(G FUNCTION)
PROGRAMMING B-63944EN-1/04
2 PREPARATORY FUNCTION (G FUNCTION)
A number following address G determines the meaning of the command for the concerned block.
G codes are divided into the following two types.
Type Meaning
One-shot G code The G code is effective only in the block in which it is specified.
Modal G code The G code is effective until another G code of the same group is specified.
(Example)
G01 and G00 are modal G codes in group 01.
G01 X_ ;
Z_ ; G01 is effective in this range.
X_ ;
G00 Z_ ; G00 is effective in this range.
X_ ;
G01 X_ ;
:
There are three G code systems in the lathe system : A,B, and C (Table 2 (a)). Select a G code system
using bits 6 (GSB) and 7 (GSC) parameter No. 3401. To use G code system B or C, the corresponding
option is needed. Generally, OPERATOR’S MANUAL describes the use of G code system A, except
when the described item can use only G code system B or C. In such cases, the use of G code system B or
C is described.
Explanation
1. When the clear state (bit 6 (CLR) of parameter No. 3402) is set at power-up or reset, the modal G
codes are placed in the states described below.
(1) The modal G codes are placed in the states marked with
(2) G20 and G21 remain unchanged when the clear state is set at power-up or reset.
(3) Which status G22 or G23 at power on is set by bit 7 (G23) of parameter No. 3402. However,
G22 and G23 remain unchanged when the clear state is set at reset.
(4) The user can select G00 or G01 by setting bit 0 (G01) of parameter No. 3402.
(5) The user can select G90 or G91 by setting bit 3 (G91) of parameter No. 3402.
When G code system B or C is used in the lathe system, setting bit 3 (G91) of parameter No.
3402 determines which code, either G90 or G91, is effective.
2. G codes other than G10 and G11 are one-shot G codes.
3. When a G code not listed in the G code list is specified, or a G code that has no corresponding
option is specified, alarm PS0010 occurs.
4. Multiple G codes can be specified in the same block if each G code belongs to a different group. If
multiple G codes that belong to the same group are specified in the same block, only the last G code
specified is valid.
5. If a G code belonging to group 01 is specified in a for drilling, the canned cycle for drilling is
cancelled. This means that the same state set by specifying G80 is set. Note that the G codes in
group 01 are not affected by a G code specifying a canned cycle.
6. When G code system A is used, absolute or incremental programming is specified not by a G code
(G90/G91) but by an address word (X/U, Z/W, C/H, Y/V). Only the initial level is provided at the
return point of the canned cycle for drilling..
7. G codes are indicated by group.
as indicated in Table.
