WARNING

Programmable mirror image

Note that programmed operations vary
considerably when a programmable mirror image is
enabled.

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.

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 User’s 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.

s-10

WARNING

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.

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.

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.

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.

PRECAUTIONS

s-11

WARNING

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.

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.

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.

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.

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.

WARNINGS RELATED TO DAILY MAINTENANCE

WARNING

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 User’s Manual (Common to T/M series) for
details of the battery replacement procedure.

WARNING

Absolute pulse coder battery replacement

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.

Refer to the FANUC SERVO MOTOR

series

Maintenance Manual for details of the battery
replacement procedure.

WARNING

3 Fuse

replacement

Before replacing a blown fuse, however, it is
necessary to locate and remove the cause of the
blown fuse.
For this reason, only those personnel who have
received approved safety and maintenance training
may perform this work.

When replacing a fuse with the cabinet open, be
careful not to touch the high-voltage circuits
(marked

and fitted with an insulating cover).

Touching an uncovered high-voltage circuit
presents an extremely dangerous electric shock
hazard.
