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 magnetics cabinet.
- Be aware of the weight of the amplifier and other components.
Servo 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 careful 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. Securely tighten each target screw with the specified tightening torque.
- Insulate all exposed parts that are charged.
- Never touch the regenerative discharge resistor or radiator directly.
The surface of the radiator and regenerative discharge resistor 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.
- 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 mist or water droplets are attached to an electric 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 power magnetics cabinet that satisfies IP54.
WARNING
- 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.
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 this manual.
- Protect the amplifier from impact.
Do not place anything on 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 and 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.
CAUTION
- 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.
- Notes relating to this product storage, transportation and environment
This servo amplifier uses electronic parts corroded by the halogen (fluorine, chlorine, bromine, iodine, etc.)
Do not storage or transport or use this servo amplifier in the halogen (fluorine, chlorine, bromine, iodine, etc.) atmosphere.
Fumigant and industrial cleaning solvent, and pesticide might contain the halogen.
Note
NOTE
- Keep the nameplate clearly visible.
- Keep the legend on the nameplate clearly visible.
- After unpacking the amplifier, carefully check for any damage.
- Mount the amplifier in a location where it can be easily accessed periodic inspection and daily maintenance.
- Leave sufficient space around the machine to enable maintenance to be performed easily.
Do not place any heavy objects such that they would interfere with the opening of the doors.
- Keep the parameter table and spare parts at hand.
Also, keep the specifications at hand. These items must be stored in a location where they can be retrieved immediately.
- Provide adequate shielding.
A cable to be shielded must be securely connected to the ground plate, using a cable clamp or the like.
WARNINGS AND CAUTIONS RELATING TO A PILOT RUN
Warning
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.
WARNING
- 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 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.
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 specified 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.
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 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 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 amplifiers 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 on; Place the machine in the emergency stop state so that the power being input to the amplifier is shut off. 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 alarm number.
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.
Caution
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 power element will be damaged.
- Securely tighten each target screw with the specified tightening torque. - 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
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.
- Unless otherwise specified, do not insert or remove any connector while the power is turned on. Otherwise, the amplifier may fail.
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.

CONFIGURATION
Chapter 1, "CONFIGURATION," consists of the following sections: 1.1 FEATURES OF THE αi-B SERIES SERVO AMPLIFIER 1.2 DIFFERENCES FROM THE αi AMPLIFIERS
1.3 DIFFERENCES BETWEEN THE LEVEL-UP αi-B AMPLIFIER AND THE αi-B AMPLIFIER 1.4 CONFIGURATION
1.5 SERVO AMPLIFIERS
1.6 LINEUP
1.1
FEATURES OF THE
αi-B SERIES SERVO AMPLIFIER
The αi-B series servo amplifier (hereinafter called the "αi-B amplifier") employs a modular structure, and is thinner, conserves more space, outputs less heat, and saves more energy.
Compact
(1) A latest low-loss power device and a newly developed highly-efficient radiator are used to provide compact servo amplifiers.
(2) The shape of the cable connector is improved to reduce the length of cable projection into the cabinet.
Energy saving
(1) All models from small- to large-capacity ones use power regeneration as standard to save energy. (2) A latest low-loss power device is used to output less heat.
Reduction in cabling
(1) Spindle amplifiers are made available with FSSB to enable both servo and spindle amplifiers to be connected to the CNC only with optical fiber cables.
(2) Amplifiers can be connected with one cable.
(3) 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 power magnetics cabinet 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 power magnetics cabinet of servo amplifier is substantially reduced.
Improved maintainability
(1) A radiator cooling fan motor can now be replaced without removing the unit from the power magnetics cabinet.
(2) The smart trouble shooting function allows you to check diagnostic information useful for locating the cause of a servo or spindle alarm on the CNC screen.
(3) The input voltage of the Power Supply can now be monitored, which makes it easier to locate the cause of an alarm issued due to an abnormality in the input power supply.
(4) Connectors are attached to the input power lines and motor power lines, which makes it easier to replace a servo amplifier with another one.
(5) 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.
Preventive maintenance
(1) A leakage detection function is included, which can detect any sign of insulation degradation of a motor or power line automatically with a high degree of accuracy.
Enhanced lineup
(1) The 60 mm-wide model without external fin is added to the αiPS-B 200 V input model. (2) The 300 mm-wide model is added to the αiPS-B 400 V input model.
(3) The 3-axis servo amplifier is added to the αiSV-B 400 V input model. (4) The αiSVP-B series is added, which is optimum for automatic lathe.
1.2
