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
SAFETY PRECAUTIONS
B-65285EN/03
-
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

SAFETY PRECAUTIONS
1.2.2
B-65285EN/03
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.

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.

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.

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

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
maintenance arises.

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

START-UP PROCEDURE (OVERVIEW)
Make sure that the specifications of the CNC, servo motors, servo
amplifiers, and other units you received are exactly what you ordered,
and these units are connected correctly. Then, turn on the power.
(1) Before turning on the circuit breaker, check the power supply
voltage connected.
→ See Section 3.2.
(2) Some types of PSM, SVM, and SPM require settings before the
system can be used. So check whether you must make settings.
→ See Section 3.3.
(3) Turn on the power, and set initial parameters on the CNC.
For the initialization of servo parameters, refer to the following
manual:
FANUC AC SERVO MOTOR αis/αi series Parameter Manual
(B-65270EN)
For the initialization of spindle parameters, refer to the following
manual:

VRDY-OFF Alarm Indicated on the CNC Screen
When the VRDY-OFF alarm is indicated on the CNC, check the items
listed below. In addition, VRDY-OFF can occur also for reasons other
than listed below. If the following items turn out to have not caused
VRDY-OFF, check diagnosis information No. 358 (V ready-off
information) on the diagnosis screen and report it to FANUC.
(1) Communication interface between amplifier and module
Is the cable for the communication interface (CXA2A/B) between
the amplifier and module connected correctly?
(2) Emergency stop signal (ESP)
Has the emergency stop signal (connector: CX4) applied to the
PSM been released? Alternatively, is the signal connected
correctly?
(3) MCON signal
Hasn't setting up the axis detach function disabled the
transmission of the ready command signal MCON from the CNC
to the SVM?
(4) SVM control printed-circuit board
The SVM control printed-circuit board may be poorly installed or
faulty. Be sure to push the faceplate as far as it will go. If the
problem persist, replace the control printed-circuit board.
On the Series 16i/18i/21i/0i/PMi, checking diagnosis information
(DGN) No. 358 makes it possible to analyze the cause of the VRDYOFF alarm.
(Supported servo software: Series 90B0/D(04) and subsequent
editions)
Diagnosis
358
V ready-off information
Convert the displayed value to binary form, and check bits 5 to 14 of
the resulting binary number.
When the servo amplifier starts working, these bits become 1
sequentially, starting at bit 5. When the servo amplifier has started
normally, all of bits 5 to 14 become 1.
Check bits 5 to 14 sequentially, starting at the lowest-order bit. The
first lowest bit that is not 0 corresponds to the processing that caused
the V ready-off alarm.

When cutting is not performed, the spindle vibrates, making
noise.
(1) The spindle vibrates only when the spindle speed has reached or is
at a particular speed level.
Check whether the spindle also vibrates when the motor is turning
by inertia. If noise is unchanged, investigate the source of
mechanical vibration. There are several methods to turn the
spindle by inertia as explained below. Because these methods
involve machine sequences, consult with the machine tool
builder.
A. Setting spindle control signal MPOF (FS16i: G73#2, FS15i:
G228#2) to 1 immediately causes the spindle to turn by
inertia.

Observing Data Using the Spindle Check Board
4.3.6.1
Overview
B-65285EN/03
By using the check board, you can convert digital signals used for
control in the spindle amplifier module to analog voltage, and observe
the conversion result with an oscilloscope. For internal data
observation, you can use CH1 and CH2 (output: -5 to +5 V) as the
two-channel analog output, and CH1D and CH2D as the output for
checking specific bits of bit data or the like. You can also view internal
data on the five-digit indicator.

By setting data using four DIP switches on the check board, you can
output internal data to the five-digit display, analog voltage output
circuit, channels 1 and 2 (LM and SM or CH1 and CH2).
Data on channels 1 and 2 is the one from an 8-bit D/A convertor.

Specifying data to be monitored
<1> Press the four setting switches at the same time for at least a
second ."FFFFF" will be displayed on the indicator.
<2> Turn off the switches and press the "MODE" switch. "d-00" will
be displayed on the indicator and the system will enter the mode
for monitoring internal data.
<3> In this mode, the motor can be operated normally.
Press the "UP" or "DOWN" switch while holding down the
"MODE" switch. The indicator display will change in the range of
"d-00" to "d-12".
<4> The following shows the correspondence between the
destinations of the internal data of the serial spindle and addresses
d-01 to d-12.
d-01 to d-04: Specifies the amount of data to be output to the
indicator, data shift, and output format (decimal
or hexadecimal).
d-05 to d-08: Specifies the amount of data to be output to the
channel 1, data shift, and whether an offset is
provided.
d-09 to d-12: Specifies the amount of data to be output to the
channel 2, data shift, and whether an offset is
provided.
<5> Select address d-xx in the procedure for setting data described in
<3>.
<6> Turn off the "MODE" switch. "d-xx" will disappear 0.5 second
later, and the data will be displayed for a second.
Change the set data using the "UP" or "DOWN" switch within the
second the data is displayed.
<7> When more than a second elapses without pressing the "UP" or
"DOWN" switch, data cannot be changed.
If the "MODE" switch is turned on or off, however, setting can be
started from the beginning of the step in item <6>.

If a low battery voltage or a battery voltage of 0 V is indicated by
an APC (absolute Pulsecoder) alarm, replace the battery.
If a battery voltage of 0 V is indicated, you need to make a zero
point return.
The absolute Pulsecoder of the αis/αi series servo motor is
incorporated with a backup capacitor as standard. This backup
capacitor enables an absolute position detection to be continued
for about 10 minutes. Therefore, no zero point return need be
performed if the time during which servo amplifier power is kept
off for battery replacement is within 10 minutes.
On the contrary, the absolute Pulsecoder of the standard α series
servo motor is not incorporated with a backup capacitor. Be
careful when replacing the battery for this Pulsecoder. See
[Caution No. 1 for battery replacement] at the end of this section
for details.
The service life of the batteries is about two years if they are used
in a six-axis configuration with αis/αi series servo motors and one
year if they are used in a six-axis configuration with α series servo
motors.
FANUC recommends that you replace the batteries periodically
according to the battery service life.
The battery unit consists of four R20 alkaline batteries.
Commercial batteries can be used in the battery unit. The optional
battery offered by FANUC is A06B-6050-K061.

START-UP PROCEDURE
5.PERIODIC MAINTENANCE OF SERVO AMPLIFIER
WARNING
1 When using the built-in batteries (A06B-6073K001), do not connect them to the BATL (B3) of
connector CXA2A/CXA2B.
The output voltages from different SVM batteries
may be short-circuited, resulting in the batteries
becoming very hot.
2 Do not connect more than one battery to the same
BATL (B3) line. If the output voltage is different
between the batteries, they may be short-circuited,
resulting in the batteries becoming very hot.
3 Install the battery with correct polarity. If the battery
is installed with incorrect polarity, it may overheat,
blow out, or catch fire.
[Installation procedure for the battery]
(1) Remove the battery cover from the SVM.
(2) Install the battery in the SVM as shown in the figure below.
(3) Install the battery cover.
(4) Attach the battery connector to CX5X of the SVM.

CAUTION
1 When the battery is installed in the SVM from the
side from which the cable is drawn, the cable may
be stretched tight, which can lead to a poor contact
condition. Therefore, install the battery so that the
cable is not extended tightly.
2 Be careful when handling the connector. See
[Caution No. 2 for battery replacement] at the end of
this section for details.

B-65285EN/03
[Caution No. 1 for battery replacement]
The Pulsecoder for the α series servo motor is not incorporated with a
backup capacitor as standard. To keep the absolute position
information in the absolute Pulsecoder, you need to keep the control
power turned on during battery replacement. Follow the procedure
explained below.
[Replacing procedure for the battery]
1. Make sure that the power to the SVM is on (the 7-segment LED
on the front of the SVM is on).
2.
Make sure that the emergency stop button of the system has been
pressed.
3.
Make sure that the motor is not activated.
4.
Make sure that the DC link charge LED of the SVM is off.
5.
Remove the old battery, and install a new battery.
6.
This completes the replacement. You can turn off the power to the
system.

WARNING
When replacing the battery, be careful not to touch
bare metal parts in the panel. In particular, be
careful not to touch any high-voltage circuits due to
the electric shock hazard.
Before replacing the battery, check that the DC link
charge confirmation LED on the front of the servo
amplifier is off. Neglecting this check creates an
electric shock hazard.
Install the battery with correct polarity. If the battery
is installed with incorrect polarity, it may overheat,
blow out, or catch fire.
Avoid a short-circuit between the +6 V and 0 V lines
of a battery or cable. A short-circuit may lead to a
hot battery, an explosion, or fire.

POWER SUPPLY MODULE (PSM, PSMR)
If an alarm occurs, in the STATUS display, the ALM LED lights red,
and the one-digit 7-segment display indicates an alarm code or warning
code.
The meaning of each warning code is the same as that of the
corresponding alarm code. If a warning code is displayed, an alarm
condition will occur in a certain period of time. The PSM or PSMR
remains operable while the warning code stays displayed.
Example of an alarm
Example of a warning

3.1.1
Alarm Code 1 (PSM)
For the PSM-5.5i to PSM-15 i
(1) Meaning
The main circuit power module (IPM) has detected an abnormal
condition.
(2) Cause and troubleshooting
(a) Control supply voltage decrease of the power module (IPM)
→ Replace the power unit.
(b) Input supply voltage imbalance
→ Check the input power supply specification.
(c) The specification of the AC reactor does not match the PSM
in use.
→ Check the PSM and the specification of the AC reactor.
(d) IPM failure
→ Replace the IPM.
For the PSM-15i to PSM-37i
(1) Meaning
Overcurrent flowed into the input of the main circuit.
(2) Cause and troubleshooting
(a) Input supply voltage imbalance
→ Check the input power supply specification.
(b) The specification of the AC reactor does not match the PSM
in use.
→ Check the PSM and the specification of the AC reactor.
(c) IGBT defective
→ Replace IGBT.

→ Clean the cooling system with a vacuum cleaner or the
factory air blower.
(c) Overload
→ Examine the operating conditions.
(d) Poor installation of the control printed-circuit board
→ Be sure to push the faceplate as far as it will go. (This
alarm may be displayed if one of the connectors for
connection between the control printed-circuit board
and power printed-circuit board is detached.)
3.1.4
Alarm Code 4 (PSM, PSMR)
(1) Meaning
In the main circuit, the DC voltage (DC link) has dropped.
(2) Cause and troubleshooting
(a) A small power dip has occurred.
→ Check the power supply.
(b) Low input power supply voltage
→ Check the power supply specification.

(1) Make sure that the motor is not vibrating.
Þ If a motor vibrates, the current flowing in it becomes more
than necessary, resulting in an alarm.
(2) Make sure that the power lead to the motor is connected correctly.
Þ If the connection is incorrect, an abnormal current flows in
the motor, resulting in an alarm.
(3) Make sure that the following parameters are set correctly.
Þ An overload alarm is issued based on the result of calculation
of these parameters. Be sure to set them to the standard values.
For details of the standard values, refer to the FANUC AC

(4) Attach the check board to connector JX5 to measure the
waveform of the actual current (IR and IS) of the servo amplifier
module. (This check pin board differs from that for the α series.)
Run the motor and measure its actual currents (IR and IS). Then
compare the measurement results with the overload duty curve
shown in "FANUC AC SERVO MOTOR αis/αi series
Descriptions (B-65262EN)," and see whether the machine load is
too heavy compared with the motor capacity. If the actual current
is high on acceleration/deceleration, it is likely that the time
constant is too small.

variation is small relative to the velocity feedback pulse
variation. This means that this alarm is not issued when a
semi-full is used. Check if the separate detector outputs
position feedback pulses correctly. If position feedback
pulses are output correctly, it is considered that the motor
alone is rotating in the reverse direction at the start of
machine operation because of a large backlash between the
motor position and scale position.

Before replacing fuses or printed-circuit boards,
make sure that the recharge-under-way LED (red)
is off.
Before replacing fuses or printed circuit boards, see the table given
below to find which section or subsection in this manual provides
information about the related replacement procedure.
NOTE
1 If a fuse blows, it is likely that there is a short-circuit
in the power supply for a device (such as a sensor)
connected to the servo amplifier.
After checking that all devices connected to the
servo amplifier are normal, replace the fuse.
If you do not remove the cause, it is very much likely
that the fuse will blow again.
2 Do not use any fuse not supplied from FANUC.
3 Before replacing a fuse, check a marking on it with
that on the printed-circuit board. Be careful not to
mount a fuse with an incorrect rating.

SERVO MOTOR MAINTENANCE
Generally, αis/αi series AC servo motors have no parts that wear off or
that must be replaced periodically, unlike DC servo motors, which have
brushes that must be replaced periodically.
However, you should perform periodic maintenance for servo motors
so as to keep their initial performance as long as possible and to prevent
breakdowns. AC servo motors have precision sensors. Their incorrect
use or damage caused during transportation or assembling can result in
breakdowns or accidents. We recommend that you inspect the servo
motors periodically according to the descriptions given below.

MOTOR MAINTENANCE
B-65285EN/03
RECEIVING AND KEEPING AC SERVO MOTORS
When you receive an AC servo motor, make sure that:
• The motor is exactly the one you ordered, in terms of model, shaft,
and sensor specifications.
• No damage has been caused on the motor.
Because FANUC inspects servo motors strictly before shipment, you
do not, in principle, have to inspect them when you receive them.
The servo motors should be kept indoors as a rule. The storage
temperature range is -20 to +60°C. Do not place or install AC servo
motors in the place where:
• It is extremely humid and dew is prone to form,
• There is a steep change in temperature,
• There is constant vibration, which may cause damage to the shaft
bearings, or
• There is lots of dust and trash.

DAILY INSPECTION OF AC SERVO MOTORS
Before starting operation, or periodically (once a week or month), you
should inspect the AC servo motors in terms of the following:
(1) Vibration and noise
Check the motor for abnormal vibration (by the hand) and noise
(by the ear) when the motor is:
• Not rotating
• Rotating at low speed
• Accelerating or decelerating
If you find anything unusual, contact your FANUC service staff.
(2) Damage on the outside
Check the Pulsecoder cover (red plastic) for crevices and the
motor surface (black coating) for scratches and cracks.
If you find a crevice in the Pulsecoder cover, you should replace it.
For how to replace, see the description about the Pulsecoder in
Section 1.4. If you are not sure about replacement, contact you
FANUC service staff.
If there is a scratch or crack on the motor surface, the user should
repair it by himself as required. If coating has come off, dry the
portion of interest (or the entire surface) and coat it with paint for
machines such as urethane paint.

(3) Stains and smudges
Check the motor surface and bolt holes for oil or cutting fluid.
Wipe off oil and cutting fluid on the motor surface periodically.
Oil or cutting fluid can damage the coating by chemical reaction,
possibly leading to a failure.
Also check how such a liquid leaks onto the motor, and repair if
needed.
Wipe off oil and cutting fluid on the motor
surface periodically.
(4) Overheating
Check to see if the motor is too hot during normal operation.
Attach a thermolabel on the motor surface and check it visually to
see if the motor becomes too hot during normal operation.
CAUTION
Temperature on the motor surface can exceed
80°C under some conditions. Never touch it by
the hand.
Attach a thermolabel and
check it visually.

PERIODIC INSPECTION OF AC SERVO MOTORS
We recommend that you inspect the AC servo motors for the following
items at least once a year.
(1) Observation of torque command (TCMD) and speed command
(VCMD) waveforms
Observe normal voltage waveforms with an oscilloscope, and
keep notes of them. During periodic inspection, check the current
waveforms with the records.
The waveforms vary according to the operating conditions such as
load and cutting speed. Note that you should make comparisons
under the same condition (for example, during fast traverse to the
reference position or low-speed cutting).
See descriptions on the check boards in FANUC AC Servo Motor
αis/αi series Parameter Manual (B-65270EN) for detailed inspection
procedures.
(2) Diagnosis by waveforms
Check the measured waveforms to see whether:
<1> The peak current is within the limit to the current in the
amplifier during rapid traverse, acceleration, or
deceleration.(TCMD)
The limit to the amplifier current is listed below. A voltage
of 4.44 V is indicated when the current flowing through the
amplifier is equal to the current limit for the amplifier
(common to all models).

The motor used to accelerate/decelerate with the amplifier
current within the limit (the acceleration/deceleration torque
used to be sufficient), but something is wrong now. If this is
the case, the probable causes are:
• The load conditions in the machine have changed because
of changed friction or reduced machine efficiency after
long period of use.
• Motor failure
Increased friction

(2) Checking the insulation between the winding and frame
Use a megohmmeter to measure the insulation resistance on 500
VDC. From the measurement result, determine whether the
insulation is acceptable or not according to the following criteria:
• More than 100 MΩ : Acceptable
• 10 to 100 MΩ
: Deterioration has started. Although
there is no performance problem,
periodic check is required.
• 1 to 10 MΩ
: Deterioration is in an advanced state.
Special care must be taken. Periodic
check is required.
• Less than 1 MΩ
: Unacceptable. Replace the motor.
CAUTION
1 Before measuring insulation resistance, disconnect
the connection to the spindle amplifier module. If
insulation resistance is measured with the spindle
amplifier module connected, the spindle amplifier
module may be damaged.
2 During the measurement of insulation resistance,
applying voltage to the motor for a long time may
further deteriorate the insulation of the motor.
Therefore, the measurement of insulation resistance
should be performed in a minimum amount of time
where possible.

2.SPINDLE MOTOR MAINTENANCE MOTOR MAINTENANCE
B-65285EN/03
NOTE
1 When using a belt, adjust the tension of the belt so
that the allowable value listed above is not
exceeded.
If the machine tool is to run with the allowable value
exceeded, examine use of support bearings in the
machine tool so that its reliability can be maintained
for a long time. (If the allowable value is exceeded, it
is likely that noise may have occurred.)
2 When the belt tension center is positioned beyond
the end of an output axis, the allowable load
becomes smaller than that at the end of the output
axis.
3 If a load in the thrust direction is put on a helical
gear, the shaft shifts in the thrust direction. As a
rule, therefore, avoid such a load on the helical
gear.
