SAFETY PRECAUTIONS   

 
This section describes the safety precautions related to the use of CNC 
units.  
It is essential that these precautions be observed by users to ensure the 
safe operation of machines equipped with a CNC unit (all descriptions 
in this section assume this configuration). Note that some precautions 
are related only to specific functions, and thus may not be applicable 
to certain CNC units. 
Users must also observe the safety precautions related to the machine, 
as described in the relevant manual supplied by the machine tool 
builder. Before attempting to operate the machine or create a program 
to control the operation of the machine, the operator must become 
fully familiar with the contents of this manual and relevant manual 
supplied by the machine tool builder.

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. 

 

SAFETY PRECAUTIONS

 

 

B-63944EN/03 

 

s-4 

 WARNING 

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 User’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. 

 

 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.

 SAFETY 

PRECAUTIONS

 

 

s-5 

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 User’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. 

 

B-63944EN/03

 

 SAFETY 

PRECAUTIONS

 

 

s-7 

 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.
