s-1

SAFETY PRECAUTIONS B-65262EN/06

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. Refer to Chapter 7,

“OUTLINE DRAWINGS” for details.

- 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 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.

- 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.

- Do not enter the area under the vertical axis without securing safety.

If a vertical axis drop occurs unexpectedly, you may be injured.

s-2

B-65262EN/06 SAFETY PRECAUTIONS

WARNING

- 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.

- Make sure that the load inertia ratio is not greater than specified value.

If the motor stops from its maximum rotational speed with greater than specified load inertia ratio, the resistor element of the dynamic brake may become abnormally hot, possibly causing damage to the dynamic brake and a fire.

- 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 Chapter 6, "SPECIFICATIONS".)

- 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.

s-3

SAFETY PRECAUTIONS B-65262EN/06

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 maintenance manual (B-65285EN or B-65325EN).

- 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 how to connect cables to motors, refer to Chapter 7, “OUTLINE DRAWINGS”.

- 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 Chapter 3, “USAGE” 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-4

B-65262EN/06 SAFETY PRECAUTIONS

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.

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 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.

s-5

SAFETY PRECAUTIONS B-65262EN/06

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 Chapter 6, “SPECIFICATIONS”, 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.

Insulation resistance Judgment

100 MΩ or higher Acceptable

10 to 100 MΩ

1 to 10 MΩ

Lower than 1 MΩ Unacceptable. Replace the motor.

The winding has begun deteriorating. There is no problem with the performance at present. Be sure to perform periodic inspection. The winding has considerably deteriorated. Special care is in need. Be sure to perform periodic inspection.

CAUTION LABEL

The following label is attached to the motor. Attach this label to a prominent place on the motor to call attention to the user.

Heat caution label

(compliance with the IEC

standard)

Heat caution label

Since the motor is heated to a high temperature during operation or immediately after a stop, touching the motor may cause a burn. So, attach this label to a prominent place to call attention when the surface is exposed and may be touched.

Remark:

The mark of this label conforms to the IEC standard, which is a global standard.

The mark has the meaning of heat caution, so the description is omitted.

1.GENERAL B-65262EN/06

1.2 FEATURE

The FANUC AC Servo Motor αi series has been designed for machine tool feed axis applications. This servo motor α

Compact

The use of a latest magnet and the optimized mechanical design reduce the total length and weight, therefore realizing light, compact motors.

Smooth rotation

The special magnetic pole shape which minimizes torque ripples which, when combined with precise current control and accurate Pulsecoder feedback, enables extremely smooth motor rotation.

Excellent acceleration

The use of a special rotor shape brings small and light motors, and a high level of torque. These motors, therefore, provide excellent acceleration characteristics.

Wide continuous-operating zone

High-density winding, low iron loss by the optimum core shape, and the use of the latest servo software reduce heat generation during high-speed rotation to a minimum and allow a wide continuous operating zone.

Controllability

The use of the latest servo software maintains controllability even when a disturbance occurs.

High reliability

A totally-enclosed, friction-free brushless design is used. This allows the servo motors to be used in demanding environments with no need for special checks or maintenance.

Excellent drip-proofing

The use of waterproof connectors and FANUC's unique stator seal provide excellent drip-proofing, which prevent ingress of liquid, such as coolant.

Built-in, high-precision encoder

A low-indexing-error optical encoder (Pulsecoder) is built into the motors. This Pulsecoder enables precise positioning. Pulsecoders have the resolution of 1,000,000 or 16,000,000 per revolution. As such, the motors can be used for positioning applications ranging from simple positioning to those requiring a high degree of precision.

Powerful brake

A powerful brake with an increased holding torque is available as an option. The brake uses an asbestos-free design.

200-V and 400-V power supply specifications

A lineup of 400-V power supply specification motors is provided in addition to the 200-V power supply specification motors. A suitable motor can be selected according to the local power supply specification.

3.USAGE B-65262EN/06

3 USAGE

This chapter explains how to connect the FANUC AC Servo Motor αi series to the CNC system and how to install it in the machine.

Chapter 3, "USAGE", consists of the following sections:

3.1 USE ENVIRONMENT FOR SERVO MOTORS...............................................................................12

3.2 CONNECTING A SERVO MOTOR .................................................................................................19

3.3 MOUNTING A SERVO MOTOR......................................................................................................21

3.1 USE ENVIRONMENT FOR SERVO MOTORS

3.1.1 Ambient Temperature, Humidity, Installation Height, and

Vibration

Ambient temperature

The ambient temperature should be 0°C to 40°C. If the ambient temperature exceeds this range, the operating conditions must be eased to prevent the motor and detector from overheating. (The values in the data sheet are determined for an ambient temperature of 20°C.)

Ambient humidity

The ambient humidity should be 80%RH or less and no condensation should not be caused.

Installation height

Up to 1,000 meters above the sea level requires, no particular provision for attitude. When operating the machine at a higher level, special care is unnecessary if the ambient temperature is lowered 1°C at every 100m higher than 1,000m. For example, when the machine is installed at a place of 1,500 meters above sea level, there is no problem if the ambient temperature is 35°C or less.

Vibration

When installed in a machine, the vibration applied to the motor must not exceed 5G.

If any one of the four environmental conditions (ambient temperature, ambient humidity, installation height, and vibration) specified above is not satisfied, the output must be restricted.

3.1.2 Usage Considering Environmental Resistance

Overview

The motor is an electric part, and if the lubricant or cutting fluid falls on the motor, it will enter the inside of the motor, possibly adversely affecting the motor. In particular, if the cutting fluid adheres to the motor, it will deteriorate the resin or rubber sealing members, causing a large amount of cutting fluid to enter the inside of the motor and possibly damaging the motor. When using the motor, note the points described below.

Level of motor protection

For the standard type, the level of motor protection is such that a single motor unit can satisfy IP65 of the IEC 60034-5 standard, and a single motor unit of α IEC 60034-5 standard. (Except the fan motor and the connectors of models with a fan. The connectors of

Pulsecoders are water-proof when engaged.) As options, IP67 type motors are also available. (Except models with a fan and the α above. The connectors of Pulsecoders are water-proof when engaged.)

For a description of the drip-proof and water-proof properties of each connector, see the section on that connector.

IP4□ : Machine protected from introduction of solid foreign matter over 1.0 mm Electric cables and wires with a diameter or thickness greater than 1.0 mm do not enter.

IP6□ : Fully dust-proof machine Structure completely free from the entry of dust.

IP□4 : Machine protected form water spray Water sprayed on the motor from any direction will have no harmful effect.

IP□5 : Machine protected from injected water Water injected from a nozzle to the machine in any direction does not have a harmful impact on the

machine.

IP□7 : Machine protected from the effect of seeping water If the machine is immersed in water at a prescribed pressure for a prescribed duration, there is no

possibility that an amount of water that has a harmful impact on the machine enters the machine.

If sufficient water-proof performance is required, as in the case in which a motor is used in a cutting fluid mist atmosphere, specify an IP67 type motor. Note that both the standard and IP67 types satisfy the provisions for short-time water immersion, and do not guarantee their water-proof performance in an atmosphere in which the cutting fluid is applied directly to the motor. Before actual use, note the points described below.

Motor periphery

If the cutting fluid or lubricant falls on the motor, it will adversely affect the sealing properties of the motor surface, entering the inside of the motor and possibly damaging the motor. Note the following points on use.

Make sure that the motor surface is never wet with the cutting fluid or lubricant, and also make sure that no fluid builds up around the motor. If there is a possibility of the surface being wet, a cover is required. Be sure to mount a cover even when using an IP67 type motor.

3.USAGE B-65262EN/06

If the cutting fluid is misted, the cutting fluid may be condensed on the inside of the cover and fall on the motor. Make sure that no condensed droplets fall on the motor.

Completely separate the machining area from the motor area, using a telescopic cover, accordion curtain, and so on. Note that partitions such as accordion curtains are consumable and require periodic inspection for damage.

Output shaft seal (oil seal)

For all models, the shaft of the servo motor is provided with an oil seal to prevent entry of oil and other fluids into the motor. It does not, however, completely prevent the entry of lubricant and other fluids depending on the working conditions. Note the following points on use.

When the motor is rotating, the oil seal has an effect of discharging any oil that enters, but if it is pressurized for a long time when the motor is stopped, it may allow oil to enter through the lip. When lubrication with an oil bath is conducted for gear engagement, for example, the oil level must be below the lip of the oil seal of the shaft, and the oil level must be adjusted so that the oil does nothing but splash on the lip.

If the shaft is directed upward so that it is constantly immersed in oil, the oil seal of the motor alone does not provide sufficient sealing. If grease is used for lubrication, the properties of the oil seal are generally impaired. In these cases, a special design is required. For example, another oil seal is mounted on the machine side and a drain is provided so that any oil passing through that seal can is discharged outside.

Oil, grease

Drain hole

Oil seal

In such an environment in which the lip of the oil seal switches between dry and wet states repeatedly, if the cutting fluid flies about after the lip has worn in a dry state, the cutting fluid may easily enter the inside of the motor. In this case, provide a cover, etc. so that no cutting fluid is applied to the oil seal of the motor.

Ensure that no pressure is applied to the lip of the oil seal.

The cutting fluid does not provide lubrication for the oil seal lip, so that the fluid may easily enter the seal. Provide a cover so that no cutting fluid is applied to the oil seal.

The oil seal lip is made of rubber, and if foreign matters such as cutting chips get in, it will be easily worn, losing its sealing properties. Provide a cover, etc. to prevent cutting chips from entering near the lip.

Motor coupling

If a coupling box exists between the motor and the machine, employ the structure described below so that no cutting fluid builds up in the box.

Provide a cover for the top and sides of the coupling box.

Provide a drain hole at the bottom of the coupling box. The hole must be large enough to avoid clogging. Make sure that any cutting fluid that bounces back is not applied from the drain hole to the motor.

The cutting fluid leaks from a gap in the accordion curtain to the motor area, and builds up in the coupling box. While the motor is moving, the cutting fluid ripples, splashing on the oil seal of the motor.

The cutting fluid enters the inside of the motor there in large quantities, deteriorating the insulation of the motor.

There is a gap, so the cutting fluid enters the motor area.

Connectors

Note the following points on use:

Make sure that no cutting fluid is introduced to the motor via cables. If the motor connector is used horizontally, this can be accomplished by forming a slack in the cable.

If the motor connector is directed upward, the cutting fluid collects into the cable connector. Whenever possible, direct the motor connector sideways or downward.

If there is a possibility of the power cable and the power connector being wet, it is recommended to use the water-proof connector plug recommended in this DESCRIPTIONS for the connector and a oil-proof cable as the power cable. (Oil-proof cable example: PUR (polyurethane) series made by LAPP)

If using a conduit hose for cable protection purposes, use the seal adapter recommended in this DESCRIPTIONS.
