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.

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.

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 highly-efficient radiator makes it possible to reduce the depth of the fin to 100 mm, therefore reducing the depth of the amplifier.
(2)The width of the amplifier is reduced, and therefore the amplifier requires an average of approximately 30% smaller installation space in the cabinet than the conventional amplifiers.
(3)The shape of the cable connector is improved to reduce the length of cable projection into the control board.
Reduction in cabling
(1)Amplifiers can be connected with one cable.
(2)A ground connection from the motor output terminal block to the 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.)
Connector attachment to power lines
(1)Connectors are attached to input power lines and motor power 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.
Improved maintainability
(1)A fan motor can now be replaced in an instant manner, so that the time required to replace a fan motor is reduced substantially.
(2)Connectors are attached to input power lines and motor power lines, so that the time required for servo amplifier replacement is reduced substantially.
(3)The need to perform reference position return operation after 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.

NOTE
1For how to use the αi PS together with the αi SV and αi SP, see Chapter 4, "HOW TO SELECT THE MODULE".
2A magnetic contactor, AC line filter, and circuit breakers are always required.
3To protect the unit from surge currents caused by lightning, connect surge absorbers between lines, and between the lines and ground, at the power inlet of the power magnetic cabinet. See
APPENDIX A for details.
4When using the 3φ fan motor, breaker 2 can be shared.

Units prepared by the machine tool builder
NOTE
1For how to use the αi PSR together with the αi SV and αi SP, see Chapter 4, "HOW TO SELECT THE MODULE".
2A magnetic contactor, AC line filter, and circuit breakers are always required.
3To protect the unit from surge currents caused by lightning, connect surge absorbers between lines, and between the lines and ground, at the power inlet of the power magnetic cabinet. See
APPENDIX A for details.
4When an insulating transformer is installed, high-frequency noise to the Power Supply is reduced, so the AC line filter is not required. If the insulating transformer is installed outside the power magnetic cabinet, and the cable connecting the amplifier is exposed, the cable must be covered with a grounded metal duct, or an AC line filter must be installed.
5When using the 3φ fan motor, breaker 2 can be shared.
