SAFETY PRECAUTIONS
FANUC SERVO MOTOR series
This Safety Precautions section describes the precautions which must be observed to ensure safety when using
FANUC servo motors (including spindle motors). Users of any servo motor model are requested to read this
manual carefully before using the servo motor.
The users are also requested to read this manual carefully and understand each function of the motor for correct
use.
The users are basically forbidden to do any behavior or action not mentioned in this manual. They are invited
to ask FANUC previously about what behavior or action is prohibited.

DEFINITION OF WARNING, CAUTION, AND NOTE
This manual includes safety precautions for protecting the user and preventing damage to the
machine. Precautions are classified into Warning and Caution according to their bearing on safety.
Also, supplementary information is described as a Note. Read the Warning, Caution, and Note
thoroughly before attempting to use the machine.
WARNING
Applied when there is a danger of the user being injured or when there is a damage of both the user
being injured and the equipment being damaged if the approved procedure is not observed.
CAUTION
Applied when there is a danger of the equipment being damaged, if the approved procedure is not
observed.
NOTE
The Note is used to indicate supplementary information other than Warning and Caution.
` Read this manual carefully, and store it in a safe place. B65232EN/02

WARNING
WARNING
F
Be safely dressed when handling a motor.
Wear safety shoes or gloves when handling a motor as you may get hurt on any edge or protrusion
on it or electric shocks.
F
Use a crane or lift to move a motor from one place to another.
Motors are heavy. When moving them, use a crane or lift as required. (For the weight of motors,
refer to their respective specification manuals.)
When moving a motor using a crane or lift, use a hanging bolt if the motor has a corresponding
tapped hole, or textile rope if it has no tapped hole. If a motor is attached with a machine or any
other heavy stuff, do not use a hanging bolt to move the motor as the hanging bolt and/or motor
may get broken. When moving a motor, be careful not to apply excessive force to its windings
as the windings may break and/or their insulation may deteriorate.
F
Do not touch a motor with a wet hand.
A failure to observe this caution is vary dangerous because you may get electric shocks.
F
Before starting to connect a motor to electric wires, make sure they are
isolated from an electric power source.
A failure to observe this caution is vary dangerous because you may get electric shocks.
F
Do not bring any dangerous stuff near a motor.
Motors are connected to a power line, and may get hot. If a flammable is placed near a motor,
it may be ignited, catch fire, or explode.
F
Be sure to ground a motor frame.
To avoid electric shocks, be sure to connect the grounding terminal in the terminal box to the
grounding terminal of the machine.
F
Do not ground a motor power wire terminal or shortcircuit it to another
power wire terminal.
A failure to observe this caution may cause electric shocks or a burned wiring.
: Some motors require a special connection such as a winding changeover. Refer to their
respective motor specification manuals for details. SAFETY PRECAUTIONS

WARNING
F
Connect power wires securely so that they will not get loose.
A failure to observe this caution may cause a wire to be disconnected, resulting in a ground fault,
short circuit, or electric shock.
F
Do not supply the power to the motor while any terminal is exposed.
A failure to observe this caution is very dangerous because you may get electric shocks if your
body or any conductive stuff touches an exposed terminal.
F
Do not get close to a rotary section of a motor when it is rotating.
A rotating part may catch your cloths or fingers. Before starting a motor, ensure that there is no
stuff that can fly away (such as a key) on the motor.
F
Before touching a motor, shut off the power to it.
Even if a motor is not rotating, there may be a voltage across the terminals of the motor.
Especially before touching a power supply connection, take sufficient precautions. Otherwise
you may get electric shocks.
F
Do not touch any terminal of a motor for a while (at least 5 minutes) after
the power to the motor is shut off.
High voltage remains across power line terminals of a motor for a while after the power to the
motor is shut off. So, do not touch any terminal or connect it to any other equipment. Otherwise,
you may get electric shocks or the motor and/or equipment may get damaged.
F
To drive a motor, use a specified amplifier and parameters.
An incorrect combination of a motor, amplifier, and parameters may cause the motor to behave
unexpectedly. This is dangerous, and the motor may get damaged.
F
Do not touch a motor when it is running or immediately after it stops.
A motor may get hot when it is running. Do not touch the motor before it gets cool enough.
Otherwise, you may get burned.
F
Be careful not get your hair or cloths caught in a fan.
Be careful especially for a fan used to generate an inward air flow.
Be careful also for a fan even when the motor is stopped, because it continues to rotate while the
amplifier is turned on.
F
Ensure that motors and related components are mounted securely.
If a motor or its component slips out of place or comes off when the motor is running, it is very
dangerous. B65232EN/02

CAUTION
CAUTION
F
FANUC motors are designed for use with machines. Do not use them for
any other purpose.
If a FANUC motor is used for an unintended purpose, it may cause an unexpected symptom or
trouble. If you want to use a motor for an unintended purpose, previously consult with FANUC.
F
Ensure that a base or frame on which a motor is mounted is strong
enough.
Motors are heavy. If a base or frame on which a motor is mounted is not strong enough, it is
impossible to achieve the required precision.
F
Be sure to connect motor cables correctly.
An incorrect connection of a cable cause abnormal heat generation, equipment malfunction, or
failure. Always use a cable with an appropriate current carrying capacity (or thickness). For how
to connect cables to motors, refer to this manual.
F
Ensure that motors are cooled if they are those that require forcible
cooling.
If a motor that requires forcible cooling is not cooled normally, it may cause a failure or trouble.
For a fancooled motor, ensure that it is not clogged or blocked with dust and dirt. For a
liquidcooled motor, ensure that the amount of the liquid is appropriate and that the liquid piping
is not clogged. For both types, perfor
