1.2.1
Warning
WARNING
-
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.
-
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 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. For details, refer to Chapter
7, "OUTLINE DRAWINGS," in B-65262EN.
-
When connecting a cord such as a power line to the terminal block, use
specified tightening torque to firmly connect the cord.
If operation is performed with a loose terminal, the terminal block can overheat, resulting in a fire.
Moreover, a terminal can be detached, resulting in a ground fault, short circuit, or electric shock.
-
Do not apply current when a terminal of the terminal block or the crimp
terminal of a power line is exposed.
If the hand or a conductive object touches a terminal of the terminal block or the crimp terminal of a power
line, you may get electric shocks. Attach an insulation cover (accessory) onto the terminal block. Moreover,
cover the crimp terminal at the tip of a power line with an insulation tube.
-
Assemble and install a power connector securely.
If a power line is detached due to a failure in crimping or soldering, or a conductive area is exposed due to
a failure in shell assembly, you may get electric shocks.
-
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 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 20 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.
-
On the machine, install a stop device for securing safety.
The brake built into the servo motor is not a stop device for securing safety. The machine may not be held if
a failure occurs.

SAFETY PRECAUTIONS
B-65285EN/04
WARNING
-
Do not enter the area under the vertical axis without securing safety.
If a vertical axis drop occurs unexpectedly, you may be injured.
-
Fasten a motor firmly before driving the motor.
If a motor is driven when the motor is not fastened firmly or is fastened insufficiently, the motor can tumble
or is removed, resulting in a danger. If the motor mounting section is not sufficiently strong, the machine
may be damaged or the user may be injured.
-
Do not get close to a rotary section of a motor when it is rotating.
When a motor is rotating, clothes or fingers can be caught, resulting in an injury.
-
Do not drive a motor with an object such as a key exposed.
An object such as a key can be thrown away, resulting in an injury. Before rotating a motor, check that there
is no object that is thrown away by motor rotation.
-
Do not apply a radial load exceeding the "allowable radial load".
The shaft can break, and components can be thrown away. When the vertical axis is involved, a vertical axis
drop can occur.
-
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 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 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.
A motor is heavy, so that if you lift a motor by hand, you may be exposed to various risks. For example, the
waist can be damaged, and the motor can drop to injure you. Use equipment such as a crane as needed. (For
the weight of a motor, see Specification manual (B-65262EN).)
-
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.
-
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.
-
Install the components around a motor securely.
If a component is displaced or removed during motor rotation, a danger can result.

SAFETY PRECAUTIONS
1.2.2
Caution
CAUTION
-
Use the eyebolt of a motor to move the motor only.
When a motor is installed on a machine, do not move the machine by using the eyebolt of the motor.
Otherwise, the eyebolt and motor can be damaged.
-
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.
For pulse coder replacement, refer to the Subsection III-1.2.6.
-
Do not machine and modify a motor.
Do not machine and modify a motor in any case except when motor machining or modification is specified
by FANUC. Modifying a motor may cause a failure or trouble in it.
-
Do not conduct dielectric strength or insulation test for a sensor.
Such a test can damage elements in the sensor.
-
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 details, refer to Chapter
7, “OUTLINE DRAWINGS” in the Specification manual (B-65262EN).
-
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. Plastic components and sensors can be damaged easily. So, handle those
components very carefully. In particular, do not lift a motor by using a plastic component, connector,
terminal block, and so forth.
-
Do not step or sit on a motor, and do not put a heavy object 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 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.
-
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 Specification manual
(B-65262EN) 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.
s-5
SAFETY PRECAUTIONS
B-65285EN/04
CAUTION
-
Do not use the brake built into a motor for braking.
The brake built into a servo motor is designed for holding. If the brake is used for braking, a failure can
occur.
-
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 is not clogged. For both types,
perform regular cleaning and inspection.
-
When storing a motor, put it in a dry (non-condensing) place at room
temperature (0 to 40 °C).
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.
-
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.
1.2.3
Note
NOTE
-
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.
-
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.
-
When testing the winding or insulation resistance of a motor, satisfy the
conditions stipulated in IEC60034.
Testing a motor under a condition severer than those specified in IEC60034 may damage 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 the
Specification manual (B-65262EN).
-
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 the Specification manual (B-65262EN), or ask FANUC. For
insulation resistances, see the following table.
s-6
B-65285EN/04
SAFETY PRECAUTIONS
NOTE
-
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 the Specification manual (B-65262EN), or ask
FANUC. For insulation resistances, see the following table.
MOTOR INSULATION RESISTANCE MEASUREMENT
Measure an insulation resistance between each winding and motor frame using an insulation resistance
meter (500 VDC). Judge the measurements according to the following table. Make an insulation
resistance measurement on a single motor unit after detaching cords such as a power line.

Warnings and Cautions Relating to Mounting
1.3.1.1 Warning
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.
Be extremely careful with power supply lines, motor power lines, and DC link connections through
which a large amount of current passes, because a loose screw (or poor contact in a connector or poor
connection between a connector terminal and a cable) may cause a fire.
-
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.
-
Ensure that the cables used for the power supply lines and power lines are of the appropriate
diameter and temperature ratings.
-
Do not apply an excessively large force to plastic parts.
If a plastic section breaks, it may cause internal damage, thus interfering with normal operation. The
edge of a broken section is likely to be sharp and, therefore, presents a risk of injury.

-
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.
-
Connect the power supply lines and power lines to the appropriate terminals and connectors.
-
Connect the signal lines to the appropriate connectors.
-
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.
-
Apply appropriate countermeasures against noise.
Adequate countermeasures against noise are required to maintain normal operation of the amplifier.
For example, signal lines must be routed away from power supply lines and power lines.

1.3.2.2 Caution
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 sensors.
Following the instructions given in the maintenance manual, adjust the position and speed sensors for
the spindle so that an appropriate waveform is obtained.
If the sensors 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.

Notes on replacing a fuse or PC board
1)
Before starting the replacement work, ensure that the circuit breaker protecting the power
magnetics cabinet is open.
2)
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.
3)
Some PC board components become extremely hot. Be careful not to touch these components.
4)
Ensure that a fuse having an appropriate rating is used.
5)
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.
6)
After replacing the fuse, ensure that the screws are firmly tightened. For a socket-type fuse,
ensure that the fuse is inserted correctly.
7)
After replacing the PC board, ensure that it is securely connected.
8)
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.
-
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.

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
1)
A dirty heat sink or fan results in reduced semiconductor cooling efficiency, which degrades
reliability. Periodic cleaning is necessary.
2)
Using compressed air for cleaning scatters the dust. A deposit of conductive dust on the amplifier
or peripheral equipment will result in a failure.
3)
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.
1.3.3.3 Note
NOTE
-
Ensure that the battery connector is correctly inserted.
If the power is shut off while the battery connector is not connected correctly, the absolute position
data for the machine will be lost.
-
Store the manuals in a safe place.
The manuals should be stored in a location where they can be accessed immediately it so required
during maintenance work.
-
Notes on contacting FANUC

3.1
START-UP PROCEDURE (OVERVIEW)
Make sure that the specifications of the CNC, servo motors, servo amplifiers, and other units you received
are exactly what you ordered, and these units are connected correctly. Then, turn on the power.
(1) Before turning on the circuit breaker, check the power supply voltage connected.
→ See Section 3.2.
(2) Some types of Power Supply, Servo Amplifier, and Spindle Amplifier require settings before the
system can be used. So check whether you must make settings.
→ See Section 3.3.
(3) Turn on the power, and set initial parameters on the CNC.
For the initialization of servo parameters, refer to the following manual:
FANUC AC SERVO MOTOR αi series Parameter Manual (B-65270EN)
For the initialization of spindle parameters, refer to the following manual:
FANUC AD SPINDLE MOTOR αi series Parameter Manual (B-65280EN)
(4) For start-up adjustment and troubleshooting, see Chapter 4.

CONNECTING THE POWER
3.2.1
Checking the Voltage and Capacity of the Power
Before connecting the power, you should measure the AC power voltage.
Table 3.2.1 (c) and (b) list the input power specification for the Power Supply. Use a power source with
sufficient capacity so that the system will not malfunction due to a voltage drop even at a time of peak load.
