SAFETY PRECAUTIONS |
1.2 FANUC AC SERVO MOTOR αis/αi series FANUC AC SPINDLE MOTOR αi series
1.2.1 Warning
WARNING
-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. If you lift the motor by hand, you may get a backache, or you may be seriously injured when you drop the motor. A suitable crane or lift must be used to move the motor. (For the weight of motors, refer to their respective specification manuals.)
When moving a motor using a crane or lift, use a hanging bolt if the motor has a corresponding tapped hole, or textile rope if it has no tapped hole.
If a motor is attached with a machine or any other heavy stuff, do not use a hanging bolt to move the motor as the hanging bolt and/or motor may get broken.
-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.
-Be sure to secure power wires.
If operation is performed with a terminal loose, the terminal block may become abnormally hot, possibly causing a fire. Also, the terminal may become disconnected, causing a ground fault or short-circuit, and possibly giving you electric shocks. See the section in this manual that gives the tightening torque for attaching power wires and short-bars to the terminal block.
-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.
-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 their respective motor specification manuals for details.
s-3
SAFETY PRECAUTIONS |
B-65285EN/03 |
WARNING
-Do not supply the power to the motor while any terminal is exposed.
A failure to observe this caution is very dangerous because you may get electric shocks if your body or any conductive stuff touches an exposed terminal.
-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.
-Do not get close to a rotary section of a motor when it is rotating.
You may get your clothes or fingers caught in a rotary section, and may be injured. Before starting a motor, ensure that there is no stuff that can fly away (such as a key) on the motor.
-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.
-To drive a motor, use a specified amplifier and parameters.
Driving a motor with other than the specified combinations of an amplifier and parameters may cause the motor to perform an unexpected operation; for example, the motor may get out of control, or produce excessively high torque. This may result in the motor or machine being damaged. Also, an object such as a workpiece or tool may fly off due to excessive rotation, possibly causing injury.
s-4
B-65285EN/03 |
SAFETY PRECAUTIONS |
-Do not touch a regenerative discharge unit for a while (at least 30 minutes) after the power to the motor is shut off.
A regenerative discharge unit may get hot when the motor is running.
Do not touch the regenerative discharge unit before it gets cool enough. Otherwise, you may get burned.
-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.
-Ensure that motors and related components are mounted securely.
If a motor or its component slips out of place or comes off when the motor is running, it is very dangerous.
-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.
-When designing and assembling a machine tool, make it compliant with EN60204-1.
To ensure the safety of the machine tool and satisfy European standards, when designing and assembling a machine tool, make it compliant with EN60204-1. For details of the machine tool, refer to its specification manual.

B-65285EN/03 |
1.2.2 Caution
CAUTION
-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.
-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.
-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 their respective specification manuals.
-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 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.

B-65285EN/03 |
SAFETY PRECAUTIONS |
1.2.3 Note
NOTE
-Do not step or sit 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 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.
-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.
For a nameplate for a built-in spindle motor, keep the nameplate with the spindle.
-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. Be very careful when handling plastic portions, sensors, and windings, because they are very liable to break. Especially, avoid lifting a motor by pulling its plastic portion, winding, or power cable.
-Do not conduct dielectric strength or insulation test for a sensor.
Such a test can damage elements in the sensor.
-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 IEC34 may damage the motor.
-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.
-Do not modify a motor.
Do not modify a motor unless directed by FANUC. Modifying a motor may cause a failure or trouble in it.
s-7
SAFETY PRECAUTIONS |
B-65285EN/03 |
NOTE
-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 their respective specification manuals 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.
-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.
-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 their respective specification manuals, 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.

s-17
SAFETY PRECAUTIONS |
B-65285EN/03 |
WARNING
-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.

SAFETY PRECAUTIONS |
1.3.3.2Caution
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 IPM will be damaged.
-Tighten all screws firmly.
-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.
