General Safety Precautions

- When an abnormality such as an alarm or a hardware failure occurs, the operations

described in the specifications are not guaranteed unless otherwise specifically noted.

When action corresponding to the abnormality is specifically described, take the action.

When no action is described, please contact FANUC.

- The signals and functions described in the specifications cannot be used separately for

safety functions unless otherwise described as being usable for the safety functions.

Their specifications are not assumed to be used as the safety functions in this case, an

unexpected danger may be caused. For information about the safety functions, please

contact FANUC.

Generally, the safety functions represent functions that protect the operators from

machine danger.

- A wrong device connection or setting can lead to unpredictable operation. When

starting to operate the machine for the first time after assembling the machine, replacing

components, or modifying parameter settings, exercise the greater care by, for example,

reducing the torque limit value, error detection level, or operating speed or by operating

the machine in such a way that an emergency stop can be made quickly.

s-2

B-65282EN/06 SAFETY PRECAUTIONS

WARNINGS AND CAUTIONS RELATING TO MOUNTING

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
magnetic 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.

s-3

SAFETY PRECAUTIONS B-65282EN/06

WARNING

- Close the amplifier cover after completing the wiring.
Leaving the cover open presents a danger of electric shock.

- Confirm that the input voltage meets the specifications of the

amplifier before making connection.

If the input voltage exceeds the specified value (for example, if
the input voltage for a 200-V input amplifier is 400 V), an internal
component may be damaged and burnt out.

- Prevent conductive, flammable, or corrosive foreign matters,

mists, or water droplets from entering the unit

If conductive or flammable foreign matters enter the unit,
explosion or corruption may be caused.
If corrosive or conductive mists or water droplets are attached to
an electronic circuit, unexpected operation may be caused in the
circuit.
The electronic circuit portion must be installed in an environment
of pollution level 2 specified by IEC60664-1. To achieve
pollution level 2 in a severe machine tool environment, it is
generally necessary to install the portion in a cabinet that satisfies
IP54.

s-4

B-65282EN/06 SAFETY PRECAUTIONS

Caution

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 impact.
Do not place anything on the amplifier.

- Do not disassemble the amplifier.

- Do not block the air inlet to the radiator.

- Take appropriate measures to prevent coolant, oil mist, or

chips from being adhered to the radiator and fan motors that
are exposed to the outside of the power magnetics cabinet.

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 fan motors or
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.

- 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.

- 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.

s-5

SAFETY PRECAUTIONS B-65282EN/06

CAUTION

- 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

magnetic cabinet.

If any clearance is left between the power magnetic 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.

s-6

WARNINGS AND CAUTIONS RELATING TO A PILOT RUN

Warning

WARNING

- Before turning on the power, check that the cables connected

to the power magnetic 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 magnetic

cabinet is securely grounded.

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

power magnetic cabinet and all other doors are closed.

Ensure that the door of the power magnetic 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 magnetic

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 magnetic cabinet (by
opening both the input circuit breaker of the power magnetic
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 shut off by the magnetic contactor.

- Before opening a door or protective cover of a machine to

enable adjustment of the machine, first place the machine in
the emergency stop state and check that the motor has
stopped.

s-8

B-65282EN/06 SAFETY PRECAUTIONS

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 magnetic 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.

s-9

SAFETY PRECAUTIONS B-65282EN/06

WARNINGS AND CAUTIONS RELATING TO MAINTENANCE

Warning

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 circuit board

1) Before starting the replacement work, ensure that the circuit
breaker protecting the power magnetic 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 circuit 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 circuit board to be
replaced. If a modification drawing number is indicated,
contact FANUC before replacing the circuit board.

Also, before and after replacing a circuit 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 circuit 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 circuit 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.

s-10

B-65282EN/06 SAFETY PRECAUTIONS

WARNING

- Notes on replacing the battery of the absolute Pulsecoder
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 αi 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 magnetic 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
magnetic 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.

s-11

SAFETY PRECAUTIONS B-65282EN/06

Caution

CAUTION

- Ensure that all required components are mounted.

When replacing a component or circuit 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, circuit board, and
other components.

When replacing a fuse or circuit board, first check the

specification code of the fuse or circuit board, then mount it in
the correct position. The machine will not operate normally if a
fuse or circuit board having other than the correct specification
code is mounted, or if a fuse or circuit 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

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.

- 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
magnetic cabinet and amplifier.

- Unless otherwise specified, do not insert or remove any
connector while the power is turned on. Otherwise, the
amplifier may fail.

s-12

B-65282EN/06 SAFETY PRECAUTIONS

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

Inform FANUC of the details of an alarm and the specification

code of the amplifier so that any components required for
maintenance can be quickly secured, and any other necessary
action can be taken without delay.

1.1 FEATURES OF THE SERVO AMPLIFIER αi SERIES

The servo amplifier αi series employs a modular structure, and is
thinner, conserves more space, outputs less heat, and saves more
energy.

Compact

(1) Use of a latest low-loss power device and a newly developed

(2) The width of the amplifier is reduced, and therefore the amplifier

(3) The shape of the cable connector is improved to reduce the

Reduction in cabling

(1) Amplifiers can be connected with one cable.
(2) A ground connection from the motor output terminal block to the

Connector attachment to power lines

(1) Connectors are attached to input power lines and motor power

Improved maintainability

(1) A fan motor can now be replaced in an instant manner, so that

(2) Connectors are attached to input power lines and motor power

(3) The need to perform reference position return operation after

highly-efficient radiator makes it possible to reduce the depth of
the fin to 100 mm, therefore reducing the depth of the amplifier.

requires an average of approximately 30% smaller installation
space in the cabinet than the conventional amplifiers.

length of cable projection into the control board.

flange is included, so external cabling for this connection is no
longer required. (A connection from the top of the flange to the
system ground on the control board is required.)

lines. (For the large-capacity models, terminal blocks are used.)
The time required for power line attachment to and detachment
from the servo amplifier cabinet is substantially reduced.

the time required to replace a fan motor is reduced substantially.

lines, so that the time required for servo amplifier replacement is
reduced substantially.

servo amplifier replacement is eliminated.
The servo amplifier αi series has a built-in backup capacitor in
the Absolute Pulsecoder as standard. The capacitor enables
absolute position detection operation for about 10 minutes, so
that reference position return operation after servo amplifier or
feedback cable replacement is unnecessary.

(3) It is recommended that a capacitor unit for power-factor

improvement not be installed. This is because the capacitor unit
for power-factor improvement may adversely affect power
regeneration.

(4) The rated output of the motor is guaranteed for the rated input

voltage. If the input voltage changes, the rated output may not
appear even when the input voltage change is within the
allowable range.

(5) When the power supply is used in an area where the input

voltage is not within the range of 200 to 240 VAC, a power
transformer is required. When a power transformer is to be

(2) The power supply for αi PS control (power supply input of

CX1A) must be turned on before or at the same time when the
CNC is turned on. For the timing of power-on at the same time
when the CNC is turned on, refer to the chapter of the power
supply in the hardware connection manual of the CNC used.

(3) It is recommended that a capacitor unit for power-factor

improvement not be installed. This is because the capacitor unit
for power-factor improvement may adversely affect power
regeneration.

(4) The rated output of the motor is guaranteed for the rated input

voltage. If the input voltage changes, the rated output may not
appear even when the input voltage change is within the
allowable range.

(5) Power supply voltage for the main circuit

• The power specification of the main circuit for the 400-V
input series of the αi series servo amplifier is as follows:
<1> Star connection
<2> Neutral grounding on the power supply side
<3> A PE is provided on the power line. (The PE of the

amplifier and motor is connected to the PE of the
power line.)

<4> The inter-phase voltage of the power supply is 400

VAC to 480 VAC (-15%, +10%).

• If the power supply does not satisfy the conditions above,
the power supply needs to be converted to a power supply
for neutral grounding by using a star connection and an
isolating-transformer.

• The 400-V input series of the αi series servo amplifier is
designed in compliance with the safety standard EN50178
to implement insulation design of the pattern and
components of the printed circuit board by ensuring that the
phase voltage of the power supply and the voltage between
grounds connected to the neutral point of the star
connection are AC 300 Vrms or below.

Accordingly, if the power supply does not satisfy the

conditions above, the pattern and components of the printed
circuit board are poorly insulated. This can cause very
dangerous states including a failure in servo amplifier
operation and the occurrence of a high voltage at exposed
areas.

2.2 ENVIRONMENTAL CONDITIONS

The servo amplifier αi series must be installed in a sealed type cabinet
to satisfy the following environmental requirements. For how to
design such a cabinet, see Appendix G, "EXAMPLES OF
RECOMMENDED POWER MAGNETICS CABINETS FOR
SERVO AMPLIFIER INSTALLATION".

(1) Ambient Temperature

Ambient temperature of the unit :

0 to 55°C (at operation)

-20 to 60°C (at keeping and transportation)

(2) Humidity

Normally 90% RH or below, and condensation-free

(3) Vibration

In operation : Below 0.5G

(4) Atmosphere

Prevent conductive, flammable, or corrosive foreign matters,
mists, or water droplets from entering the unit

WARNING

If conductive or flammable foreign matters enter the

unit, explosion or corruption may be caused.
If corrosive or conductive mists or water droplets are
attached to an electronic circuit, unexpected
operation may be caused in the circuit.
The electronic circuit portion must be installed in an
environment of pollution level 2 specified by
IEC60664-1. To achieve pollution level 2 in a
severe machine tool environment, it is generally
necessary to install the portion in a cabinet that
satisfies IP54.

(5) Notes on Installation

The αi series servo amplifier is designed to be installed in the
power magnetics cabinet, with its heat sink projecting through
the back of the cabinet. This carries away the heat generated by
the semiconductors, thus preventing heat from building up in the
cabinet as much as possible. Therefore, note the following when
installing the amplifier.
(a) Take appropriate measures to prevent coolant, oil mist, or

chips from being adhered to the radiator and fan motors. A
deposit of coolant, oil mist, or chips on the radiator or fan
motors can lower the cooling efficiency. In some cases, the
amplifier characteristics cannot sometimes be satisfied. The
deposit may also reduce the service life of the fan motors or
semiconductors.

- 25 -

2.SPECIFICATIONS B-65282EN/06

When outside air is drawn in to the radiator, mount an air

filter on the air inlet. In addition, ensure to seal doors and
parts where cables are drawn in and out.

(b) No dust or cutting fluid must be able to enter through the

exhaust port. The flow of cooling air must not be
obstructed.

(c) The amplifier must be installed where it can be easily

inspected, removed, and remounted for maintenance.

(d) Current lines and signal lines must be separated and noise

must be suppressed. See the section 5.3 and the connection
manual for each CNC for details.

(e) Each amplifier must be installed vertically.
(f) Servo amplifiers are to be arranged horizontally. When

arranging servo amplifiers vertically from necessity, note
the following:

1) Ensure that cooling air from a lower amplifier does not

blow directly against the upper amplifier. Otherwise,
radiation performance can degrade and the rated output
may not be satisfied.

2) Ensure that the flow of cooling air of a lower amplifier

is not impeded.

(g) Maintenance areas must be reserved for each servo

amplifier.
