SAFETY PRECAUTIONS B-64483EN/01
WARNINGS AND CAUTIONS REGARDING MOUNTING, WIRING, AND EXCHANGING
WARNING
1 Before starting mounting, wiring, and exchanging, be sure to shut off externally
supplied power. Otherwise, electrical shocks, breakdown, and blowout may
occur.
If a control unit is turned off but other units are not, it is likely that power may be
supplied to servo units, resulting in the units being damaged and workers getting
an electrical shock when the units are exchanged.
2 Voltage lingers in servo and spindle amplifiers for a while even after power has
been turned off, resulting in workers possibly getting an electrical shock when
the workers touch them. Before starting to exchange these amplifiers, wait for 20
minutes after power has been turned off.
3 Be sure to ground your control units and peripheral units in accordance with your
national grounding standards (protective grounding class C or stricter).
Otherwise, electrical shocks, breakdown, and blowout may occur.
4 In order to prevent damage that may be caused by static electricity, wear a
grounding wrist strap or take a similar protective measure before starting to
touch a printed-circuit board or unit or attach a cable.
Static electricity from human bodies can damage electrical circuits.
5 In unit replacement, specify the same settings and parameters in the newly
installed unit as those for the one removed. (For details, refer to the respective
manuals for the units.)
Operating the newly installed unit with incorrect settings or parameters will cause
the machine to behave unexpectedly, possibly leading to a damaged workpiece
or machine or injury.
6 If you notice an apparent hardware fault, such as abnormal noise, abnormal
odor, smoke, ignition, or abnormal heat, in the hardware while power is being
supplied to it, shut it off at once. These faults can cause fire, breakdown,
blowout, and malfunction.
7 The radiating fins of control units, servo amplifiers, spindle amplifiers, and other
devices can remain very hot for a while after power has been turned off, making
you get burned if you touch them. Before starting to work on them, wait and
make sure they are cool.
8 When exchanging heavy stuff, you should do so together with two or more
people.
If you try to exchange heavy stuff all by yourself, you may drop it and get hurt.
9 Wiring work in the control units and peripheral units must be done only after they
have been installed. Otherwise, electrical shocks can occur.
10 Be careful not to damage cables. Otherwise, electrical shocks can occur.
11 When working, wear suitable clothes with safety taken into account. Otherwise,
injury and electrical shocks can occur.
12 Do not work with your hands wet. Otherwise, electrical shocks and damage to
electrical circuits can occur.
s-2
B-64483EN/01 SAFETY PRECAUTIONS
CAUTION
Failing to observe any caution stated below can lead to fire, breakdown, blowout,
and malfunction.
1 Do not attach the units directly to any flammable object or install the units near
any flammable object.
2 Do not allow any foreign matter (such as a screw, metal chip, or coolant) to get
in the units.
3 Handle the units and printed-circuit boards gently because they are precision
devices. Be careful not to drop them or give a high impact to them.
4 Lay signal wires away from power wires as stated in this manual.
5 When fastening each unit or wire, be sure to observe the screw tightening torque
specified for them. If screws are tightened too weakly or too strongly, it is likely
that the unit may drop, break, or malfunction, or the wire may be short-circuited.
Do not forget to tighten all necessary screw.
6 Do not block any cooling fan air inlet or outlet. For units having no cooling fan,
allow space for natural convection cooling above and below them.
7 Be careful not to make an incorrect wiring or connection. Be sure to attach wires
and cables to their respective corresponding terminals and connectors.
8 Confirm equipment’s electrical rating stated herein. Do not apply any unspecified
voltage to the equipment.
9 Do not confuse voltage polarity. Carefully confirm the arrangement of connector
pins.
10 When making a cable assembly, press-mount, crimp, or solder the wires, using
the tool specified by the cable manufacturer.
11 Use printed-circuit boards and peripheral units that match your control unit.
12 When mounting the units, pay attention to their mass.
13 When detaching a cable from a unit, hold the connector rather than the cable.
When attaching a cable, be sure to fit its connector to the connector pins
securely. For connectors having a lock mechanism, be sure to lock them
securely.
14 As for the shielding wires of the cables specified herein, securely ground them,
using, for example, cable clamps.
15 Always use wires whose length, diameter, heat resistance, and flex resistance
match their use.

SAFETY PRECAUTIONS B-64483EN/01
WARNINGS AND CAUTIONS REGARDING DESIGNING
WARNING
1 When designing, be sure to observe all rules stated in this document and any
related manuals. Otherwise, it is likely that failure and malfunction may occur.
2 Failures in the control units and I/O units as well as input power abnormality and
communication failures can hamper the normal operation of these I/O units.
Design each I/O unit in such a way that the machine can operate safely, for
example, by providing an external safety circuit to the I/O unit so that no accident
will occur even if the I/O unit fails to operate normally.
The DO function of each I/O unit has been designed in such a way that, if a
system alarm is issued in the control unit that controls the I/O unit or the power
of the control unit or the I/O unit is turned off, the DO function of all the I/O units
is turned off. However, it is not guaranteed that the DO function is surely turned
off. So, it is requested that, if a signal regarding safety is involved, a safety circuit
external to each I/O unit must be configured. Using the dual check safety
function makes it possible to detect a single fault in a portion related to safety.
For details of the dual check safety function, refer to the FANUC Series
30i/31i/32i-MODEL B Dual Check Safety Connection Manual (B-64483EN-2).
3 Coolants containing sulfur or chlorine at a high activation level, oil-free coolants
called synthetic, and water-soluble coolants at a high alkali level, in particular,
can largely affect the CNC and peripheral units. Please note that, even if
consideration is taken to protect them from direct exposure to these coolants,
the following trouble is likely to occur.
Coolants containing sulfur or chlorine at a high activation level
•
Some coolants containing sulfur or chlorine are at an extremely high activity
level. If such a coolant adheres to the CNC or peripheral units, it reacts
chemically with a material, such as resin, of equipment, possibly leading to
corrosion or deterioration. If it gets in the CNC or peripheral units, it corrodes
metals, such as copper and silver, used as component materials, possibly
leading to a defective component.
Synthetic-type coolants having a high permeability
•
Some synthetic-type coolants whose lubricating component is, for example,
PAG (polyalkylene glycol) have an extremely high permeability. If such a
coolant is used even in equipment having a high closeness, it can readily flow
into the CNC or peripheral units through, for example, gaskets. It is likely that,
if the coolant gets in the CNC or a peripheral unit, it may deteriorate the
insulation and damage the components.
Water-soluble coolants at a high alkali level
•
Some coolants whose pH is increased using alkanolamine are so strong
alkali that its standard dilution will lead to pH10 or higher. If such a coolant
spatters over the surface of the CNC or peripheral unit, it reacts chemically
with a material, such as resin, possibly leading to corrosion or deterioration.
CAUTION
Install each control unit, display unit, MDI unit, and machine operator panel in
such a place that neither cutting chip nor coolant will spatter to them. Otherwise,
damage or malfunction may occur.

B-64483EN/01 SAFETY PRECAUTIONS
WARNINGS, CAUTIONS, AND NOTES REGARDING DAILY MAINTENANCE
WARNING
Battery replacement
Do not replace batteries unless you have been well informed of maintenance
work and safety.
When opening the cabinet and replacing batteries, be careful not to touch any
high-voltage circuit (marked with
prevention cover).
When the electric shock prevention cover has been removed, you will get an
electric shock if you touch any high-voltage circuit.
WARNING
Fuse replacement
Before replacing a blown fuse, it is necessary to remove the cause of the blown
fuse.
So, do not replace fuses unless you have been well informed of maintenance
work and safety.
When opening the cabinet and replacing fuses, be careful not to touch any
high-voltage circuit (marked with
prevention cover).
When the electric shock prevention cover has been removed, you will get an
electric shock if you touch any high-voltage circuit.
CAUTION
Handle the batteries gently. Do not drop them or give a strong impact to them.
NOTE
Each control unit uses batteries, because it must hold data, such as programs,
offset values, and parameters even when AC power for it is off.
Back up the data (programs, offset values, and parameters) regularly.
If the battery voltage becomes low, a low battery voltage alarm is displayed on
the machine operator’s panel or screen.
Once the battery voltage alarm has been displayed, replace the batteries within
one week. Otherwise, the memory contents may be lost.
For the battery replacement procedure, see Section 4.4, “Batteries”. Recollect or
discard old batteries in the way your local autonomous community specifies.

1.1 CONTROL UNIT CONFIGURATION AND COMPONENT
NAMES
The Series 30i/31i/32i series control units can roughly be categorized either as an LCD-mounted type or
stand-alone type. The LCD-mounted type is one having both control and indicator sections in it. With the
stand-alone type, the control and indicator sections are separated from each other, each being configured
as an independent unit. Described below is the configuration of each type. This manual focuses on how to
attach the connectors shown in the configuration diagrams to each device.

3.1.1 Environmental Conditions outside the Cabinet
The control unit and the peripheral units have been designed on the assumption that they are housed in
closed cabinets. In this manual "cabinet" refers to the following:
• Cabinet manufactured by the machine tool builder for housing the control unit or peripheral units;
• Operation pendant, manufactured by the machine tool builder, for housing the display unit, MDI unit,
or operator's panel.
• Equivalent to the above.
The following table lists the environmental conditions required in installing these cabinets. Section 3.3 of

(Note 1)
NOTE
1 If the control unit is installed 1000 m or higher above sea level, the allowable
upper ambient temperature of the control unit in the cabinet is changed as
follows. Assume that the allowable upper ambient temperature of the control unit
in the cabinet installed 1000 m or higher above sea level decreases by 1.0°C for
every 100 m rise in altitude.
Example)
When a control unit whose required operating ambient temperature range is
0°C to 55°C is installed 1750 m above sea level:
55°C-(1750m-1000m)/100m × 1.0°C = 47.5°C
Therefore, the allowable ambient temperature range is from 0°C to 47.5°C.
2 When using a unit having additional installation conditions, be sure to meet also
these conditions.
3.2 CAUTIONS REGARDING THE INSTALLATION DESIGN OF
MACHINE TOOL POWER MAGNETICS CABINETS
When a cabinet is designed, it must satisfy the environmental conditions described in Section 3.1. In
addition, the magnetic interference on the screen, noise resistance, and maintenance requirements must be
considered. When mounting FANUC-supplied units, such as displays and operator’s panels, use packing
and fasten the mounting screws with the specified tightening torque. When designing magnetics cabinets,
pay due consideration to each item stated in the following “CAUTION”.
CAUTION
1 The cabinet must be fully closed. The cabinet must be designed to prevent the
entry of airborne dust, coolant, and organic solvent.
2 The cabinet must be designed so that the permissible temperature of each unit
is not exceeded. (See Section 3.3.)
- 18 -
B-64483EN/01 3.INSTALLATION
CAUTION
3 A closed cabinet must be equipped with a fan to circulate the air within. (This is
not necessary for a unit with fan.) The fan must be adjusted so that the air
moves at 0.5 m/sec along the surface of each installed unit.
However, do not blow air from the fan directly to the unit, because doing so can
readily make dust attach the portion where the air flow hits, leading to possible
trouble. (This is not necessary for a unit with fan.)
4 For the air to move easily, a clearance of 100 mm is required between each unit
and the wall of the cabinet.
5 Each FANUC-supplied unit, such as a display or operator’s panel, has been
designed on the assumption that they will be mounted using packing and with
the specified screw tightening torque. Failing to mount them as specified can
lead to unit damage and/or malfunction. Be sure to use packing and observe the
specified screw tightening torque. (See Sections 3.6 and 3.7.)
6 Failing to use packing or to provide complete sealing, or using any packing not
resistant to coolant in use will allow dust, coolant, and organic solvent to get in
the cabinet, leading to possible equipment trouble. Be sure to use an appropriate
packing and a secure sealing.
In addition, use an appropriate packing and a secure sealing for the cable outlets
and doors of the machine builder-provided units, such as displays, operator’s
panels, and cabinet pendant boxes. (See Section 3.7.)
7 The LCD must not be installed in such a place that coolant would directly fall
onto the unit. Be sure to attach a protection cover to the LCD if it will be used in
an environment where it is anticipated that coolant may come into contact with it,
for example, an environment with a relatively dense oil mist.
8 Noise must be minimized. As the machine and the control unit are reduced in
size, the parts that generate noise may be placed near noise-sensitive parts in
the magnetics cabinet.
The control unit is built to protect it from external noise. Cabinet design to
minimize noise generation and to prevent it from being transmitted to the control
unit is necessary. (See Section 3.4.)
9 When placing units in the cabinet, also consider ease of maintenance. The units
should be placed so that they can be checked and replaced easily when
maintenance is performed.
10 The hard disk drive and floppy disk drive must not be installed near the source of
a strong magnetic field.
11 The installation conditions of the I/O unit and connector panel I/O module must
be satisfied. In order to secure ventilation in the equipment, mount the I/O unit
and connector panel I/O module in the specified orientation. Clearances of 100
mm or more both above and below the I/O unit are required for wiring and
ventilation.
Equipment radiating too much heat must not be put below the I/O unit and
connector panel I/O module.

3.INSTALLATION B-64483EN/01
3.3 THERMAL DESIGN OF THE MACHINE TOOL MAGNETIC
CABINET
The internal air temperature of the cabinet increases when the units and parts installed in the cabinet
generate heat. Since the generated heat is radiated from the surface of the cabinet, the temperature of the
air in the cabinet and the outside air balance at certain heat levels. If the amount of heat generated is
constant, the larger the surface area of the cabinet, the less the internal temperature rises. The thermal
design of the cabinet refers to calculating the heat generated in the cabinet, evaluating the surface area of
the cabinet, and enlarging that surface area by installing heat exchangers in the cabinet, if necessary.
Such a design method is described in the following subsections.
3.3.1 Temperature Rise within the Machine Tool Magnetic Cabinet
The cooling capacity of a cabinet made of sheet metal is generally 6 W/°C per 1m2 surface area, that is,
when the 6W heat source is contained in a cabinet having a surface area of 1 m
2
, the temperature of the air
in the cabinet rises by 1°C. In this case the surface area of the cabinet refers to the area useful in cooling,
that is, the area obtained by subtracting the area of the cabinet touching the floor from the total surface
area of the cabinet. There are two preconditions : The air in the cabinet must be circuited by the fun, and
the temperature of the air in the cabinet must be almost constant. For example, the operator’s panel
cabinet may contain an LCD-mounted type control unit or the display of a stand-alone type control unit.
To keep the temperature in the cabinet at 58°C or below when the ambient temperature is 45°C, the
equation below must be satisfied.
Internal heat loss P [W] ≤
2
6[W/m
⋅°C] × surface area S[m2] × 13[°C] of rise in temperature
(A cooling capacity of 6 W/°C assumes the cabinet is so large that agitation with the fan motor does not
make the temperature distribution uniform. For a small cabinet like the operator's panel, a cooling
capacity of 8 W/°C, indicated in Subsection 3.3.3, may be used.)
For example, a cabinet having a surface area of 4m
2
has a cooling capacity of 24W/°C. To limit the
internal temperature increase to 13°C under these conditions, the internal heat must not exceed 312W. If
the actual internal heat is 360W, however, the temperature in the cabinet rises by 15°C. When this
happens, the cooling capacity of the cabinet must be improved using the heat exchanger.
For the power magnetic cabinet containing a stand-alone type control unit, the internal temperature rise
must be suppressed to 55°C or less, instead of 58°C.

3.4 COUNTERMEASURES AGAINST NOISE AND
GROUNDING
In general, noise can occur because of electrostatic coupling, electromagnetic induction, and ground loop
and get in a control unit.
On the control unit side, due consideration is paid to a protective measure for external noise. However, it
is hard to measure the magnitude and frequency of noise quantitatively and there are lots of uncertainties
with noise. So, it is important to take measures for minimizing noise occurrence and keeping any noise
from entering the control unit in order to enhance stability in CNC-based machine tool system operation.
Grounding the power magnetics cabinet and devices is very important to prevent an electric shock and
suppress a noise influence. The CNC system uses the following three types of grounding:
(1) Signal grounding
This type of grounding is used to supply a reference potential (0 V) for the electrical signal system.
(2) Frame grounding
This type of grounding is used for safety reasons as well as to suppress external and internal noise.
For example, grounding is provided for the device frames, panels, and shielding on the interface
cables connecting the devices.
(3) System grounding (PE)
This type of grounding is used to connect frame grounds, which are provided for the individual
devices or between the units, to the ground as a system at a single point.
When designing the power magnetics cabinet, guard against noise in the machine as described in the
following section.

3.4.1 Grounding as Noise Suppression Measures
3.4.1.1 Grounding methods
Typically, noise that becomes a problem is high–frequency noise. To suppress high–frequency noise, it is
important that the devices are grounded at low impedance
(NOTE)
.
The grounding schemes for this purpose are described below.
NOTE
Impedance includes a resistance component that converts electric current to
heat as well as a component called “reactance”, and indicates a characteristic of
resistance to the flow of alternating current at a certain frequency.
(1) Multipoint grounding scheme
In this grounding scheme, when grounded at sufficiently low impedance, the cabinet metal plates are used
as ground plates, to which grounding is provided in the vicinity of each device.
This scheme has a great effect of suppressing high–frequency noise because it enables grounding to the
low–impedance metal plates of the cabinet in the shortest distance. However, the noise suppression effect
depends on the cabinet structure because the cabinet metal plates are used as ground plates.
See Subsection 3.4.1.2 for the cabinet. Fig. 3.4.1.1 (a) is a schematic wiring diagram.

Fig. 3.4.1.1 (a) Schematic diagram for multipoint grounding scheme
When the multipoint grounding scheme is adopted, the units can be grounded at low impedance, and
ground wires (wires from the unit’s ground terminal to a grounding plate) can be shortened, so that wiring
may be simplified.

CAUTION
If it is impossible to configure cabinet metal plates with a low impedance, it is
likely that noise may effect grounding circuits shared by power wires and signal
wires.
(2) Single–point grounding scheme
In this grounding scheme, grounding separation is achieved between the signal system and power system,
and grounding is provided at a single point to suppress the noise influence of the power system on the
signal system.
This scheme tends to need longer connection wires for grounding the devices. To produce a sufficient
effect of suppressing high–frequency noise, it is therefore necessary to use larger–diameter wires or use
two or more wires for each connection. Fig. 3.4.1.1 (b) is a schematic wiring diagram.

3.4.1.2 Cabinet
A cabinet is an important element in improving noise immunity and suppressing radiated noise. One of
the causes of problems related to noise immunity and radiated noise is faulty electrical continuity between
the metal plates that make up the cabinet. Typically, noise that becomes a problem is high–frequency
noise, against which measures must be taken in the cabinet design.
- 25 -
3.INSTALLATION B-64483EN/01
(1) Basic cabinet structure
A cabinet should basically be made of metal.
To improve noise immunity, there must be low–impedance electrical continuity between the metal plates
that make up the cabinet, which are the side plates, top plate, and bottom plate, and a welding–type
cabinet structure is recommended.
As for a cabinet welding method, bead welding is more suitable than spot welding for providing
low–impedance electrical continuity between the metal plates.
For an assembly–type cabinet structure, provide electrical continuity by bringing the metal plates into
direct contact with each other, without applying a coating to their joint surface areas.
In a structure that has the metal plates connected only with wires because of structural constraints,
low–impedance connections are more difficult to make than in a structure in which welding is made or
the metal plates are brought into direct contact with each other. It is necessary to maintain sufficient
levels of items such as the cross–sectional area of a wire to use, continuity of connections, and contact
areas.
Bead welding
Fig. 3.4.1.2 (a) Cabinet structure
Bring the metal plates into direct contact with each
other, without applying a coating to their joint areas.
NOTE
Explained above is how to provide cabinets with low-impedance electrical
continuity so as to increase noise immunity and to suppress noise radiation. See
Subsection 3.4.2 for conditions required to configure protective grounding
circuits.
(2) Mounting units on the cabinet
The shortest possible lengths of unit ground wires (wires from the unit’s ground terminal to a grounding
plate) should be used to make connections. A ground wire with a small conductor diameter causes
impedance to high-frequency noise to become particularly higher, leading to an insufficient grounding
effect. For the location of the ground terminal of each unit, refer to the manual relevant to the unit. The
following shows the recommended method by which the metal plate with the unit mounted is installed on
the cabinet. Care should be taken so that the cabinet and metal plate are connected to each other on their
broad areas with no coating. It is not recommended that electrical continuity be provided only by screws,
because impedance to high frequency cannot be sufficiently low.

3.4.2 Protective Ground (Grounding for Protection against Indirect
Contact)
Protection against indirect contract is intended to prevent the risk that may occur in a conductive portion
which is not charged with electricity (applied with voltage) during normal operation but may be charged
with electricity if insulation is accidentally destroyed. It must be implemented by:
- measures to prevent the occurrence of a touch voltage, or
- automatic disconnection of the supply before the time of contact with a touch voltage can become
hazardous
As for protective grounding in “automatic disconnection of the supply before the time of contact with a
touch voltage can become hazardous”, follow any standards the machine tool is supposed to meet. Some
standard examples follow:

Actuators, such as solenoids and relays, used in power magnetics cabinets need a noise suppressor.
Because an actuator, which converts electrical energy to mechanical action, is an inductive load, it
resonates with the parasitic capacitance in a circuit containing it, when it works on and off, thus
generating intermittent arcs accompanied by abrupt voltage rises and falls at its contacts, hence
electromagnetic waves interfering with electronics circuits. As a remediation measure, treat the inductive
load as described below.
1) While referencing the processing for cable groups A and B described in Subsection 3.4.4,
“Separating Signal Lines”, apply a CR snubber circuit and a diode, respectively, to an inductive load
in an AC circuit and that in a DC circuit.
2) When selecting a CR snubber or diode, observe the following cautions.
Cautions for selecting and using a CR snubber
• Use a CR snubber in an AC circuit.
A varistor, voltage clamping element, can limit the peak of an oscillating voltage waveform but
cannot relax an abrupt voltage transition . For this reason, we recommend using a CR snubber rather
than the varistor.
• Determine the rating of the resistor and capacitor in the CR snubber according to the steady-state
current I (A) and DC resistance RL (Ω) of the inductive load as follows:
)(RLRΩ≅

• A diode (freewheeling diode) can be used as a noise suppressor for a DC driver circuit.
• Determine the ratings of the diode according to the drive voltage and current for the inductive load
(such as a solenoid coil, relay, or motor) as follows:
1) Voltage rating: Approximately twice the voltage applied to the inductive load
2) Current rating: Approximately twice the steady-state current flowing through the inductive load
• Place the diode close to the inductive load in order to minimize its wiring.

3.4.6 Cable Clamp and Shield Processing
Some cables that are drawn into the control unit, servo amplifier, or spindle amplifier need shielding
(basically, every signal line needs shielding). Clamp all these cables in the way shown below. This type
of clamping works for both cable supporting and shielding. Be sure to make clamping because it is quite
important to make system operation stable. Clamping shield correctly can suppress effect from external
noise.
Partially peel the sheath off a cable and expose the shield, and press the exposed portion against the
ground bar with the clamp. Care should be taken so that the ground bar and shield have a surface contact
in a larger area. (See the figure below.)
The machine builder is requested to prepare the ground bar for cable clamping and place it as shown
below.
When the multipoint grounding scheme is used, care should be taken so that the ground bar for the shield
clamp and cabinet are connected at low impedance by, for example, preventing the cabinet side contact
surface from being coated.
- 34 -
B-64483EN/01 3.INSTALLATION
When using an in-line connector or the like to split a cable, it is necessary to connect the shield of one
portion of the cable and that of the other portion and to keep the total impedance of the two cable portions
from becoming high. Even if the connector is placed at the inlet of the cabinet, it is also necessary to use
the shield for the intra-cabinet portion of the cable all the way to the other end of the cable.

NOTE
1 Select a cable with a proper length.
2 If the cable is too long, the noise immunity may be reduced or noise may be
caused on other cables. In addition, when the excess length is coiled, the
inductance is increased and a high voltage is induced during turning on or off of
signals. This may cause a failure or a malfunction due to noise.
3 Bundle and clamp the shields of cables that lead into the control unit or amplifier
at a point, respectively, close to the unit or amplifier.

3.4.7 Lightning Surge Absorber Installation
It is recommended to install a surge absorber between input power lines and between input power lines
and the ground in order to protect equipment from thunderbolt-caused voltage surges. However, installing
a surge absorber does not always ensure protection from lightning surges.
For recommended lightning surge absorbers, refer to your respective servo amplifier descriptions.
Installation procedure
The surge-absorbing elements used for measures against surges due to lightening must be installed in the
input power unit as shown in the figure below. The figure below shows an example in which an
insulating transformer, shown by dotted lines, is not installed. If an insulating transformer is installed,
surge-absorbing element 2 (between line and ground) is not required.

3.7 DUSTPROOF MEASURES FOR CABINETS AND
PENDANT BOXES
When designing and manufacturing cabinets or pendant boxes for housing displays and operator’s panels,
they are requested to observe the following cautions to make their structures resistant to intrusion of dust,
cutting chips, coolant, organic solvent, and oil mist because these cabinets and pendant boxes are
susceptible to them.
1) The cabinet and pendant box must be of a hermetically sealed structure.
2) Apply packing to the panel mounting surface to which a display and operator's panel are to be
mounted.
3) Make sure that the door packing of the cabinet and pendant box is sealed firmly.
4) For a cabinet or pendant box with a rear cover, apply packing to the mounting surface.
5) Make sure that the cable entrance is sealed with packing, connectors for conduits, etc.
6) Make sure that all other openings are blocked, if any.
7) Pay due consideration to keep the display and operator’s panel from direct exposure to cutting chips
and coolant; do not let any coolant come into contact with them.
8) Coolant can readily form puddles on the cabinet and pendant box and may drop on the panel surface
of the display and operator’s panel. Use such a structure that can prevent coolant from forming
puddles on the display and operator’s panel or dropping on the panel surface.
- 40 -
B-64483EN/01 3.INSTALLATION
WARNING
Coolants containing sulfur or chlorine at a high activation level, oil-free coolants
called synthetic, and water-soluble coolants at a high alkali level, in particular,
can largely affect the CNC and peripheral units. Please note that, even if
consideration is taken to protect them from direct exposure to these coolants,
the following trouble is likely to occur.
- Coolants containing sulfur or chlorine at a high activation level
Some coolants containing sulfur or chlorine are at an extremely high activity
level. If such a coolant adheres to the CNC or peripheral units, it reacts
chemically with a material, such as resin, of equipment, possibly leading to
corrosion or deterioration. If it gets in the CNC or a peripheral unit, it corrodes
metals, such as copper and silver, used as component materials, possibly
leading to a defective component.
- Synthetic-type coolants having a high permeability
Some synthetic-type coolants whose lubricating component is, for example,
PAG (polyalkylene glycol) have an extremely high permeability. If such a
coolant is used even in equipment having a high closeness, it can readily flow
into the equipment through, for example, gaskets, or packing. It is likely that,
if the coolant gets in the CNC or a peripheral unit, it may deteriorate the
insulation and damage the components.
- Water-soluble coolants at a high alkali level
Some coolants whose pH is increased using alkanolamine are so strong
alkali that its standard dilution will lead to pH10 or higher. If such a coolant
spatters over the surface of the CNC or peripheral unit, it reacts chemically
with a material, such as resin, possibly leading to corrosion or deterioration.

on-time rush current imposes an extremely heavy burden on the relay contact in
the ON/OFF circuit compared with the time when the ON/OFF circuit is provided
on the AC side. So, it is necessary to select a relay that is highly resistant to rush
current. In general, a relay having a high current rating and being large in size
should be selected.
In the connection shown in Fig. 4.1.1(b), for example, use a separate 24 VDC
power supply if voltage variation due to abrupt changes in the load or rush
current may transiently exceed the rated input voltage range (24 VDC ±10%) for
the control unit or peripheral unit.
As for a control unit having the personal computer function with Windows® XP, it
is likely that input AC shut-down, such as power failure or dip, may corrupt the
contents of the hard disk or CF card. So, read the PANELi Connection and
Maintenance Manual (B-64223EN) carefully and understand its contents
sufficiently.

NOTE
Try as much as possible to avoid the configuration shown in Fig. 4.1.1(b) even
when load fluctuation and rush current are low.
In a configuration where two or more units are connected to the same 24 VDC
power supply, the control unit will not be able to start, thus failing to issue an
alarm, if the power supply fails to operate because of a fault in a unit other than
the control unit. For this reason, it is likely that it may take time to locate the fault.
If the 24 VDC power supply for the control unit and peripheral units must be
connected also to another unit because of a limited space in the power
magnetics cabinet, insert a noise filter before the 24 VDC input for the control
unit and peripheral units in order to prevent noise from the 24 VDC power supply
from entering the control unit and peripheral units after paying due consideration
to the voltage variation resulting from load fluctuation or rush current.
(Recommended noise filter: ZGB2203-01U manufactured by TDK)
4.1.2 24 VDC Power Supply Specification
Specifications of recommended 24 VDC power supply:
Output voltage: +24V±10% (21.6V to 26.4V)
(In the 24 VDC input for the control unit and peripheral units, ripple voltage and noise are contained. See
Fig. 4.1.2.)
Output current:
The continuous load current of the 24 VDC power supply is higher than or equal to the current used
by the control unit and peripheral units that are connected to the power supply.
(At the maximum temperature inside the power magnetics cabinet in which the power supply is
located. See Subsection 4.1.3.)
Load fluctuations (including rush current):
The output voltage must not go out of the above range due to load fluctuations by external DO and
other factors.
Instantaneous input interruption retention time: 10 ms or more (for -100%), 20 ms or more (for -50%)

WARNING
If the machine tool of interest has a vertical axis, it is necessary to select a 24
VDC power supply that can hold its output of 24 VDC for a prolonged time even
after the AC input has been interrupted (including power failure and
instantaneous power interruption) in order to keep a possible fall along the
vertical axis within an acceptable range. The control unit deenergizes servo
circuits if its 24 VDC input falls to 21.6 V or below. For this reason, failing to
maintain the 24 VDC input to the control unit for a satisfactory period after the
AC input has been interrupted may lead to a larger amount of fall along the
vertical axis, depending on a peripheral circuit in use, because the servo for the
vertical axis is deenergized before the peripheral circuit detects an AC input
interruption and activates the brake. In general, selecting a 24 VDC power
supply having a power capacity with a wide margin would prolong the hold time
of the 24 VDC output after an AC input interruption.

WARNING
It is impossible for the control side to control motors if the power supply is off or
there is no AC input (including power failure). It is necessary for the machine
side to perform any necessary processing.
If the control unit is used to control a vertical axis, for example, provide the motor
with a brake mechanism to prevent a fall along the vertical axis. The brake
should be controlled in such a way that the motor is clamped when the servo has
not be started or when the motor is not supposed to rotate and unclamped only
when it is supposed to rotate. It is common practice to clamp servo motors when
the servo axes cannot be controlled because of the power supply being off or of
a power failure. Even with this common practice, a fall may occur along a
controlled axis before the relay works. So, it is necessary to examine whether
the fall distance poses any problem.
Power-off: Before turning off the control unit power, be sure to apply the
brake to clamp the motor.
Power failure: On detecting a power failure, apply the brake quickly.
Turning off the control unit power results in the servo being
deenergized. So, select a 24 VDC power supply that can maintain
its 24 VDC output for a prolonged time after an AC input
interruption.

4.4.1 Battery for Memory Backup in the Control Unit (3 VDC)
Offset data, and system parameters are stored in SRAM in the control unit. The SRAM power is backed
up with the memory backup batteries held in the control unit.
When the voltage of the battery becomes low, alarm message "BAT" blinks on the LCD screen and the
battery alarm signal is output to the PMC. Upon the alarm, replace the battery as soon as possible. The
rough standard for the replacement limit is one week. However, how long the battery lasts after the alarm
varies, depending on the system configuration of interest.
If the voltage of the battery becomes any lower, memory can no longer be backed up. Turning on the
power to the control unit in this state causes system alarm to occur because the contents of memory are
lost. Clear the entire memory and reenter data after replacing the battery.
FANUC thus recommends that the battery be replaced periodically, once a year, regardless of whether a
battery alarm is issued.
The following two kinds of batteries can be used.
• Lithium battery built into the CNC control unit.
• Alkaline dry cell (size D) inserted in an external battery case attached to the control unit.
NOTE
Before shipped from FANUC, the control unit is equipped with a lithium battery
set as default. With this lithium battery, memory contents can be preserved for
one year.
4.4.1.1 Replacing the lithium battery
For LCD-mounted type control unit
Prepare a new lithium battery (ordering code: A02B-0323-K102).
(1) Turn on the power to the machine (control unit). After about 30 seconds, turn off the power.
(2) Take out the lithium battery from the rear of the control unit (by holding the latch of the lithium
battery and pulling it up while unlatching the claw held in the case).
Extract the unit while holding this
portion.
- 54 -
B-64483EN/01 4.POWER SUPPLY CONNECTION
(3) Insert a new lithium battery, prepared in advance, into the battery case (by pushing it in until the
claw of the lithium battery fits in the case). Make sure that the claw is latched securely.
Push the unit in until the
claw is latched into the
case.
WARNING
It is likely that the lithium battery may explode unless it is replaced correctly.
Do not use any battery other than the specified one (A02B-0323-K102).
CAUTION
Steps (1) to (3) should be completed within 30 minutes.
Do not leave the control unit without a battery for any longer than the specified
period. Otherwise, the contents of SRAM may be lost.
Before starting battery replacement, save the SRAM contents in a batch. They
can be restored easily even if they are lost.
Refer to the Maintenance Manual (B-64485EN) for explanations about how to
save and restore SRAM contents in a batch.
NOTE
Discard used batteries as “industrial waste” according to the rules and
ordinances of the country where the machine is installed and of the local
government that has jurisdiction over the location of the machine. When
discarding them, insulate the battery terminals with tape or the like to protect
them from short-circuiting.
For stand-alone type control unit
Prepare a new lithium battery (ordering code: A02B-0200-K102).
(1) Turn on the power to the machine (control unit). After about 30 seconds, turn off the power.
(2) Remove the lithium battery from top of the control unit.
First, pull the lithium battery cable to detach the connector. Then, take out the lithium battery from
the battery case.
The battery case is on top of the main board face plate.

4.4.1.2 Replacing commercially available alkaline dry cells (size D)
In place of the built-in lithium battery in the control unit, commercially available alkaline dry cells (size
D) can be used by installing a battery case outside the control unit and inserting the dry cells in the case.
How to connect the battery case to the control unit
For the LCD-mounted type control unit, connect the battery cable (A02B-0323-K103) to the battery case
(A02B-0236-C282). For the stand-alone type control unit, use the battery case (A02B-0236-C281), which

4.4.2 Battery for Separate Absolute Pulsecoders (6VDC)
• The absolute Pulsecoder uses a battery because it must hold data on absolute positions. When the
voltage of the batteries for absolute Pulsecoders becomes low, alarm 307 or 306 occurs, with the
following indication in the CNC state display at the bottom of the CNC screen.
Alarm 308 (alarm 2 indicating the voltage of the battery becomes low) :
The indication "APC" blinks in reversed display.
Alarm 307 (alarm indicating the voltage of the battery becomes low) :
The indication "APC" blinks in reversed display.
Alarm 306 (battery zero alarm) :
The indication "ALM" blinks in reversed display.
• When alarm 307 (alarm indicating the voltage of the battery becomes low) occurs, replace the
battery as soon as possible. In general, the battery should be replaced within one or two weeks,
however, this depends on the number of Pulsecoders used.
• When alarm 306 (battery zero alarm) occurs, Pulsecoders are reset to the initial state, in which
absolute positions are not held. Alarm 300 (reference position return request alarm) also occurs,
indicating that reference position return is required.
• In general, replace the batteries periodically within the service life listed below.
- A06B-6050-K061 or D-size alkaline dry cells (LR20) : Two years (for each six-axis
configuration)
- A06B-6073-K001 : Two years (for each three-axis configuration)
- A06B-6114-K504 : One year (for each three-axis configuration)
NOTE
The above values indicate the estimated service life of batteries used with
FANUC absolute Pulsecoders. The actual battery service life depends on the
machine configuration based on, for example, detector types. For details,
contact the machine tool builder.
Replacing batteries
To prevent absolute position information in absolute Pulsecoders from being lost, turn on the machine
power before replacing the battery. The replacement procedure is described below.
<1> Ensure that the power to the servo amplifier is turned on.
<2> Ensure that the machine is in the emergency stop state (the motor is inactive).
<3> Ensure that the DC link charge LED of the servo amplifier is off.
<4> Detach the old batteries and attach new ones.

Because the servo amplifier uses a large-capacitance electrolytic capacitor
•
internally, the servo amplifier remains charged for a while even after the power is
turned off. Before touching the servo amplifier for maintenance or other
purposes, ensure your safety by measuring the residual voltage in the DC link
with a tester and confirming that the charge indication LED (red) is off.
Be sure to replace the batteries with specified ones. Pay attention to the battery

When both this signal and the DR signal are set, the control unit can send
data. If I/O device processing is delayed by a punching operation, etc.,
control unit data sending can be stopped by turning off this signal after
sending two characters, including the data being sent currently. If this signal
will not be used, make sure to strap this signal circuit to the RS signal
circuit.

NOTE
The listed control codes are used for both EIA and ISO.
In this interface, control codes DC1 to DC4 are used.
(a) Control unit can control I/O device by issuing codes DC1 to DC4.
(b) If processing is delayed at the I/O device (when the control unit outputs data)
(i) External device can temporarily stop control unit data output by using the control unit's
CS signal. Data output stops within two characters including a currently transmitting
character when CS OFF signal is input to control unit. When CS signal is turned on again,
data transmission start.
(ii) If control code DC3 is input to control unit, control unit stops data output within ten
characters. When control code DC1 is input to control unit, control unit starts sending data
again.
