2.FANUC SERVO MOTOR series SAFETY PRECAUTIONS

B-65165E/02

2.1

WARNING

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.

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.

Do not touch a motor with a wet hand.

A failure to observe this caution is vary dangerous because you

may get electric shocks.

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.

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.

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.

Do not ground a motor power wire terminal or short-circuit 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.

B-65165E/02

SAFETY PRECAUTIONS

2.FANUC SERVO MOTOR series

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.

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.

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.

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.

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.

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.

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.

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.

SAFETY PRECAUTIONS

2.FANUC SERVO MOTOR series

2.2

CAUTION

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.

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.

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 their respective

specification manuals.

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 fan-cooled motor, ensure that

it is not clogged or blocked with dust and dirt. For a liquid-cooled

motor, ensure that the amount of the liquid is appropriate and that

the

liquid

piping

not

clogged.

For both types, perform regular cleaning and inspection.

When attaching a component having inertia, such as a pulley,

to a motor, ensure that any imbalance between the motor and

component is minimized.

If there is a large imbalance, the motor may vibrates abnormally,

resulting in the motor being broken.

Be sure to attach a key to a motor with a keyed shaft.

If a motor with a keyed shaft runs with no key attached, it may

impair torque transmission or cause imbalance, resulting in the

motor being broken.

2.FANUC SERVO MOTOR series SAFETY PRECAUTIONS

B-65165E/02

2.3

NOTE

Do not step or sit on a motor.

If you step or sit on a motor, it may get deformed or broken. Do

not put a motor on another unless they are in packages.

When storing a motor, put it in a dry (non-condensing) place

at room temperature (0 to 40 5C).

If a motor is stored in a humid or hot place, its components may

get damaged or deteriorated. In addition, keep a motor in such a

position that its shaft is held horizontal and its terminal box is at

the top.

Do not remove a nameplate from a motor.

If a nameplate comes off, be careful not to lose it. If the nameplate

is lost, the motor becomes unidentifiable, resulting in

maintenance becoming impossible.

For a nameplate for a built-in spindle motor, keep the nameplate

with the spindle.

Do not apply shocks to a motor or cause scratches to it.

If a motor is subjected to shocks or is scratched, its components

may be adversely affected, resulting in normal operation being

impaired. Be very careful when handling plastic portions, sensors,

and windings, because they are very liable to break. Especially,

avoid lifting a motor by pulling its plastic portion, winding, or

power cable.

Do not conduct dielectric strength or insulation test for a

detector.

Such a test can damage elements in the detector.

When testing the winding or insulation resistance of a motor,

satisfy the conditions stipulated in IEC34.

Testing a motor under a condition severer than those specified in

IEC34 may damage the motor.

Do not disassemble a motor.

Disassembling a motor may cause a failure or trouble in it.

If disassembly is in need because of maintenance or repair, please

contact a service representative of FANUC.

Do not modify a motor.

Do not modify a motor unless directed by FANUC. Modifying a

motor may cause a failure or trouble in it.

B-65165E/02

SAFETY PRECAUTIONS

2.FANUC SERVO MOTOR series

Use a motor under an appropriate environmental condition.

Using a motor in an adverse environment may cause a failure or

trouble in it.

Refer to their respective specification manuals for details of the

operating and environmental conditions for motors.

Do not apply a commercial power source voltage directly to a

motor.

Applying a commercial power source voltage directly to a motor

may result in its windings being burned. Be sure to use a specified

amplifier for supplying voltage to the motor.

For a motor with a terminal box, make a conduit hole for the

terminal box in a specified position.

When making a conduit hole, be careful not to break or damage

unspecified portions.

Refer to an applicable specification manual.

Before using a motor, measure its winding and insulation

resistances, and make sure they are normal.

Especially for a motor that has been stored for a prolonged period

of time, conduct these checks. A motor may deteriorate

depending on the condition under which it is stored or the time

during which it is stored. For the winding resistances of motors,

refer to their respective specification manuals, or ask FANUC.

For insulation resistances, see the following table.

To use a motor as long as possible, perform periodic

maintenance and inspection for it, and check its winding and

insulation resistances.

Note that extremely severe inspections (such as dielectric strength

tests) of a motor may damage its windings. For the winding

resistances of motors, refer to their respective specification

manuals, or ask FANUC. For insulation resistances, see the

following table.

3.1

WARNINGS AND CAUTIONS RELATING TO MOUNTING

3.1.1

WARNING

Check the specification code of the amplifier.

Check that the delivered amplifier is as originally ordered.

Mount a ground fault interrupter.

To guard against fire and electric shock, fit the factory power

supply or machine with a ground fault interrupter (designed for

use with an inverter).

Securely ground the amplifier.

Securely connect the ground terminal and metal frame of the

amplifier and motor to a common ground plate of the power

magnetics cabinet.

Be aware of the weight of the amplifier and other

components.

Control motor amplifiers and AC reactors are heavy. When

transporting them or mounting them in the cabinet, therefore, be

careful not to injured yourself or damage the equipment. Be

particularly carefull not to jam your fingers between the cabinet

and amplifier.

Never ground or short-circuit either the power supply lines or

power lines.

Protect the lines from any stress such as bending. Handle the ends

appropriately.

Ensure that the power supply lines, power lines, and signal

lines are securely connected.

A loose screw, loose connection, or the like will cause a motor

malfunction or overheating, or a ground fault.

Insulate all exposed parts that are charged.

Never touch the regenerative discharge resistor or radiator

directly.

The surface of the radiator and regenerative discharge unit

become extremely hot. Never touch them directly. An

appropriate structure should also be considered.

Close the amplifier cover after completing the wiring.

Leaving the cover open presents a danger of electric shock.

Do not disassemble the amplifier.

SAFETY PRECAUTIONS

B-65165E/02

3.1.2

CAUTION

Do not step or sit on the amplifier.

Also, do not stack unpacked amplifiers on top of each other.

Use the amplifier in an appropriate environment.

See the allowable ambient temperatures and other requirements,

given in the corresponding descriptions.

Protect the amplifier from corrosive or conductive mist or

drops of water.

Use a filter if necessary.

Protect the amplifier from impact.

Do not place anything on the amplifier.

Do not block the air inlet to the radiator.

A deposit of coolant, oil mist, or chips on the air inlet will result in

a reduction in the cooling efficiency. In some cases, the required

efficiency cannot be achieved. The deposit may also lead to a

reduction in the useful life of the semiconductors. Especially,

when outside air is drawn in, mount filters on both the air inlet and

outlet. These filters must be replaced regularly.

So, an easy-to-replace type of filter should be used.

Before connecting the power supply wiring, check the supply

voltage.

Check that the supply voltage is within the range specified in this

manual, then connect the power supply lines.

Ensure that the combination of motor and amplifier is

appropriate.

Ensure that valid parameters are specified.

Specifying an invalid parameter for the combination of motor and

amplifier may not only prevent normal operation of the motor but

also result in damage to the amplifier.

Ensure that the amplifier and peripheral equipment are

securely connected.

Check that the magnetic contactor, circuit breaker, and other

devices mounted outside the amplifier are securely connected to

each other and that those devices are securely connected to the

amplifier.

Check that the amplifier is securely mounted in the power

magnetics cabinet.

If any clearance is left between the power magnetics cabinet and

the surface on which the amplifier is mounted, dust entering the

gap may build up and prevent the normal operation of the

amplifier.

3.2.1

WARNING

Before turning on the power, check that the cables connected

to the power magnetics cabinet and amplifier, as well as the

power lines and power supply lines, are securely connected.

Also, check that no lines are slack.

Before turning on the power, ensure that the power magnetics

cabinet is securely grounded.

Before turning on the power, check that the door of the power

magnetics cabinet and all other doors are closed.

Ensure that the door of the power magnetics cabinet containing

the amplifier, and all other doors, are securely closed. During

operation, all doors must be closed and locked.

Apply extreme caution if the door of the power magnetics

cabinet or another door must be opened.

Only a person trained in the maintenance of the corresponding

machine or equipment should open the door, and only after

shutting off the power supply to the power magnetics cabinet (by

opening both the input circuit breaker of the power magnetics

cabinet and the factory switch used to supply power to the

cabinet). If the machine must be operated with the door open to

enable adjustment or for some other purpose, the operator must

keep his or her hands and tools well away from any dangerous

voltages. Such work must be done only by a person trained in the

maintenance of the machine or equipment.

When operating the machine for the first time, check that the

machine operates as instructed.

To check whether the machine operates as instructed, first specify

a small value for the motor, then increase the value gradually. If

the motor operates abnormally, perform an emergency stop

immediately.

After turning on the power, check the operation of the

emergency stop circuit.

Press the emergency stop button to check that the motor stops

immediately, and that the power being supplied to the amplifier is

3.2.2

CAUTION

Note whether an alarm status relative to the amplifier is

displayed at power-up or during operation.

If an alarm is displayed, take appropriate action as explained in

the maintenance manual. If the work to be done requires that the

door of the power magnetics cabinet be left open, the work must

be carried out by a person trained in the maintenance of the

machine or equipment. Note that if some alarms are forcibly reset

to enable operation to continue, the amplifier may be damaged.

Take appropriate action according to the contents of the alarm.

Before operating the motor for the first time, mount and

adjust the position and speed detectors.

Following the instructions given in the maintenance manual,

adjust the position and speed detectors for the spindle so that an

appropriate waveform is obtained.

If the detectors are not properly adjusted, the motor may not rotate

normally or the spindle may fail to stop as desired.

If the motor makes any abnormal noise or vibration while

operating, stop it immediately.

Note that if operation is continued in spite of there being some

abnormal noise or vibration, the amplifier may be damaged. Take

appropriate corrective action, then resume operation.

Observe the ambient temperature and output rating

requirements.

The continuous output rating or continuous operation period of

some amplifiers may fall as the ambient temperature increases. If

the amplifier is used continuously with an excessive load applied,

the amplifier may be damaged.

3.3

WARNINGS AND CAUTIONS RELATING TO MAINTENANCE

3.3.1

WARNING

Read the maintenance manual carefully and ensure that you

are totally familiar with its contents.

The maintenance manual describes daily maintenance and the

procedures to be followed in the event of an alarm being issued.

The operator must be familiar with these descriptions.

Notes on replacing a fuse or PC board

Before starting the replacement work, ensure that the circuit

breaker protecting the power magnetics cabinet is open.

Check that the red LED that indicates that charging is in

progress is not lit.

The position of the charging LED on each model of amplifier

is given in this manual. While the LED is lit, hazardous

voltages are present inside the unit, and thus there is a danger

of electric shock.

Some PC board components become extremely hot. Be

careful not to touch these components.

Ensure that a fuse having an appropriate rating is used.

Check the specification code of a PC board to be replaced. If

a modification drawing number is indicated, contact FANUC

before replacing the PC board.

Also, before and after replacing a PC board, check its pin

settings.

After replacing the fuse, ensure that the screws are firmly

tightened. For a socket-type fuse, ensure that the fuse is

inserted correctly.

After replacing the PC board, ensure that it is securely

connected.

Ensure that all power lines, power supply lines, and

connectors are securely connected.

Take care not to lose any screws.

When removing the case or PC board, take care not to lose any

screws. If a screw is lost inside the nit and the power is turned on,

the machine may be damaged.

SAFETY PRECAUTIONS

B-65165E/02

Notes on replacing the battery of the absolute pulse coder

Replace the battery only while the power is on. If the battery is

replaced while the power is turned off, the stored absolute

positioning data will be lost. Some

series servo amplifier

modules have batteries in their servo amplifiers. To replace the

battery of any of those models, observe the following procedure:

Open the door of the power magnetics cabinet; Leave the control

power of the power supply module on; Place the machine in the

emergency stop state so that the power being input to the amplifier

is shut off; Then, replace the battery. Replacement work should

be done only by a person who is trained in the related maintenance

and safety requirements. The power magnetics cabinet in which

the servo amplifier is mounted has a high-voltage section. This

section presents a severe risk of electric shock.

Check the number of any alarm.

If the machine stops upon an alarm being issued, check the alarm

number. Some alarms indicate that a component must be replaced.

If the power is reconnected without first replacing the failed

component, another component may be damaged, making it

difficult to locate the original cause of the alarm.

Before resetting an alarm, ensure that the original cause of

the alarm has been removed.

Contact FANUC whenever a question relating to

maintenance arises.

Notes on removing the amplifier

Before removing the amplifier, first ensure that the power is shut

off. Be careful not to jam your fingers between the power

magnetics cabinet and amplifier.

3.3.2

CAUTION

Ensure that all required components are mounted.

When replacing a component or PC board, check that all

components, including the snubber capacitor, are correctly

mounted. If the snubber capacitor is not mounted, for example,

the IPM will be damaged.

Tighten all screws firmly.

Check the specification code of the fuse, PC board, and other

components.

When replacing a fuse or PC board, first check the specification

code of the fuse or PC board, then mount it in the correct position.

The machine will not operate normally if a fuse or PC board

having other than the correct specification code is mounted, or if

a fuse or PC board is mounted in the wrong position.

Mount the correct cover.

The cover on the front of the amplifier carries a label indicating a

specification code. When mounting a previously removed front

cover, take care to mount it on the unit from which it was

removed.

Notes on cleaning the heat sink and fan

A dirty heat sink or fan results in reduced semiconductor

cooling efficiency, which degrades reliability. Periodic

cleaning is necessary.

Using compressed air for cleaning scatters the dust. A

deposit of conductive dust on the amplifier or peripheral

equipment will result in a failure.

To clean the heat sink, do so only after turning the power off

and ensuring that the heat sink has cooled to room

temperature. The heat sink becomes extremely hot, such that

touching it during operation or immediately after power-off

is likely to cause a burn. Be extremely careful when

touching the heat sink.
