SAFETY PRECAUTIONS

GENERAL WARNINGS AND CAUTIONS

WARNING

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.

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.

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.

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.

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.

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.

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.

WARNING

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.

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.

s-4

B-64124EN/01

SAFETY PRECAUTIONS

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 and programming manual carefully

such that you are fully familiar with their contents.

WARNING

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.

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.

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.

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.

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.

s-5

SAFETY PRECAUTIONS

B-64124EN/01

WARNING

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.

B-64124EN/01

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 and programming manual carefully,

such that you are fully familiar with their contents.

WARNING

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.

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.

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.

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.

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.

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.

s-7

SAFETY PRECAUTIONS

B-64124EN/01

WARNING

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.

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. 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.

10. 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.

11. 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.

12. 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.

13. 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.

SAFETY PRECAUTIONS

WARNINGS RELATED TO DAILY MAINTENANCE

WARNING

1. Memory backup battery replacement

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 maintenance section of the operator’s manual or programming manual for details of the

battery replacement procedure.

CAUTIONS ON

CAUTION

READING THIS

The function of an CNC machine tool system depends not

MANUAL

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.

Headings are placed in the left margin so that the reader can

easily access necessary information. When locating the

necessary information, the reader can save time by

searching though these headings.

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.

1.3

CAUTIONS ON

CAUTION

VARIOUS KINDS OF

Machining programs, parameters, variables, etc. are stored

DATA

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.
