1.1 CONTROL UNIT CONFIGURATION AND COMPONENT

NAMES

The 30i series control units are divided into two types: the
LCD-mounted type and stand-alone type.
LCD-mounted type control units have a built-in display. Stand-alone
type control units have a separate display unit. In the following
sections, the LCD-mounted type is also referred to as the
LCD-mounted type, and the stand-alone type is also referred to as the
stand-alone type.
The configuration and component names of each type are shown in
the figures given below. This manual explains how to attach the
connectors shown in these figures to devices. The numbers in
parentheses () in the figures are keyed to the item numbers of the
descriptions in this manual. The numbers in brackets [] in the figures
are connector numbers.

B-63943EN/02 3.INSTALLATION

3.1 ENVIRONMENTAL REQUIREMENTS OUTSIDE THE

CABINET

3.1.1 Environmental Conditions outside the Cabinet

The peripheral units and the control unit 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 LCD/MDI unit or operator's panel.

• Equivalent to the above.

The environmental conditions when installing these cabinets shall
conform to the following table. Section 3.3 describes the installation
and design conditions of a cabinet satisfying these conditions.

Ambient
temperature of
the cabinet

Humidity

Vibration

sea level

Environment

NOTE

If the CNC is installed 1000 m or higher above sea level, the allowable upper

ambient temperature of the CNC in the cabinet is changed as follows.

Assume that the allowable upper ambient temperature of the CNC in the cabinet

installed 1000 m or higher above sea level decreases by 1.0°C for every 100 m rise
in altitude.
Example)

The upper allowable ambient temperature of the CNC in the cabinet installed

1750 m above sea level is:
55°C - 1750/100 × 1.0°C = 47.5°C
Therefore, the allowable ambient temperature range is from 0°C to 47.5°C.
When a hard disk is used, there are the following installation conditions:
Meters above sea level (operating): -60 to 3000 m
Meters above sea level (non-operating): -60 to 12000 m

Operating 0°C to 45°C
Storage, Transport -20°C to 60°C
Temperature change 0.3°C/minute or less
Normal 75%RH or less, no condensation
Short period

Operating 0.5G or less
Non-operating 1.0G or less
Operating Up to 1000 m (Note) Meters above
Non-operating Up to 12000 m

Normal machine shop environment
(The environment must be considered if the cabinets
are in a location where the density of dust, coolant,
organic solvent, and/or corrosive gas is relatively high.)

3.3 DESIGN AND INSTALLATION CONDITIONS OF THE

MACHINE TOOL MAGNETIC CABINET

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. The cabinet design must meet the
following conditions :

(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. For actual heat design, see Section

3.4.

(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.

CAUTION

If the air blows directly from the fan to the unit, dust

easily adheres to the unit. This may cause the

unit to fail. (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) Packing materials must be used for the cable port and the door in

order to seal the cabinet.

(6) The display unit must not be installed in such a place that coolant

would directly fall onto the unit. The control unit has a
dust-proof front panel, but the unit should not be placed in a

location where coolant would directly fall onto it.
(7) Noise must be minimized.
As the machine and the CNC unit are reduced in size, the parts

that generate noise may be placed near noise-sensitive parts in

the magnetics cabinet.
The CNC unit is built to protect it from external noise. Cabinet

design to minimize noise generation and to prevent it from being

transmitted to the CNC unit is necessary. See section 3.5 for

details of noise elimination/management.
(8) 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.
(9) The hard disk drive and floppy disk drive must not be installed

near the source of a strong magnetic field.
(10) The installation conditions of the I/O unit and connector panel

I/O module must be satisfied.

- 23 -

3.INSTALLATION B-63943EN/02

To obtain good ventilation in the module, the I/O unit and

connector panel I/O module must be installed in the direction

shown in the following figure. 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.

3.4 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.

3.4.1 Temperature Rise within the Machine Tool Magnetic Cabinet

The cooling capacity of a cabinet made of sheet metal is generally 6
W/°C per 1m
contained in a cabinet having a surface area of 1 m
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] ≤
6[W/m
(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 3.4.4, may be
used.)
For example, a cabinet having a surface area of 4m
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 or more. 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.

3.5 ACTION AGAINST NOISE

The CNC has been steadily reduced in size using surface-mount and
custom LSI technologies for electronic components. The CNC also is
designed to be protected from external noise. However, it is difficult
to measure the level and frequency of noise quantitatively, and noise
has many uncertain factors. It is important to prevent both noise from
being generated and generated noise from being introduced into the
CNC. This precaution improves the stability of the CNC machine tool
system.
The CNC component units are often installed close to the parts
generating noise in the power magnetics cabinet. Possible noise
sources into the CNC are capacitive coupling, electromagnetic
induction, and ground loops.
When designing the power magnetics cabinet, guard against noise in
the machine as described in the following section.

3.5.1 Separating Signal Lines

possible.
It is more desirable to cover group B with the
shield.

Bind the cables in group C separately from
group A, or cover group C with an
electromagnetic shield.
Separate group C as far from Group B as
possible.
Be sure to perform shield processing in
Section 3.5.5.

B-63943EN/02 3.INSTALLATION

3.5.2 Ground

The CNC machine tool uses the following three types of grounding:

• Signal grounding
Signal grounding supplies a reference potential (0V) for electrical

signals.

• Grounding for protection
Grounding for protection is performed for safety reasons as well as

to shield against external and internal noise. This type of
grounding includes, for example, the equipment frames, cases and
panels of units, and the shielding on interface cables connecting the
equipment.

• Protective grounding (PE)
Protective grounding (PE) is performed to connect protection

grounds provided for equipment or between units to ground
together at one point as a grounding system.

One of the two grounding methods can be selected for the CNC:
(1) One-point grounding: See Fig. 3.5.2 (a).
(2) Grounding with a nearby ground plate: See Fig. 3.5.2 (b).

Fig. 3.5.2 (a) Example of one-point grounding

- 31 -

3.INSTALLATION B-63943EN/02

Notes on grounding

Fig. 3.5.2 (b) Example of grounding with a nearby ground plate

• The ground resistance in protective grounding (PE) must be 100

Ω or less (type D grounding).

• The cable used for protective grounding (PE) must be of a

sufficient cross section to allow current to flow safely into
protective ground (PE) if an accident such as a short-circuit
occurs. (Generally, a cross section equal to or greater than that
of the AC power cable is required.)

• The cable connected to protective ground (PE) must be

incorporated into the AC power wire such that power cannot be
supplied with the ground wire disconnected.

• A wire for connecting a unit to a nearby plate (path A in Fig.

3.5.2 (b)) must be connected to the plate with the shortest
possible length. The cross section of the wire must satisfy the
IEC connections shown below. When the breaker limits an
input current, however, the wire only needs to satisfy the
requirement of current-carrying capacity of the breaker. When
cross section conditions are defined in the unit manual, the
conditions must be satisfied.

• For plate connection, use path B to connect a PE connection plate

with a unit connection plate as shown in Fig. 3.5.2 (b).

In this case, the cable thickness varies with the capacity of the

AC input power supply for the unit mounted on each metal sheet.
Therefore, when the cross-sectional area is shown in the manual
of each unit, refer the value. Otherwise, see Table 3.5.2 below.
However, when the thickness of the connection cable for
protective earthing (PE) is exceeded, the thickness of the
connection cable for protective earthing (PE) must be used.

3.5.4 Noise Suppressor

The AC/DC solenoid and relay are used in the power magnetics
cabinet.
A high pulse voltage is caused by coil inductance when these devices
are turned on or off.
This pulse voltage induced through the cable causes the electronic
circuits to be disturbed.

Notes on selecting the spark killer

• Use a spark killer consisting of a resistor and capacitor in series.
This type of spark killer is called a CR spark killer.(Use it under
AC)

(A varistor is useful in clamping the peak voltage of the pulse

voltage, but cannot suppress the sudden rise of the pulse voltage.
FANUC therefore recommends a CR spark killer.)

• The reference capacitance and resistance of the spark killer shall
conform to the following based on the current (I (A)) and DC
resistance of the stationary coil:

Partially peel out the sheath and expose the shield. Push and clamp
by the plate metal fittings for clamp at the part. The ground plate
must be made by the machine tool builder, and set as follows :

NOTE

Select a cable with a proper length.
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 malfunction due to a failure or noise.

3.5.6 Measures Against Surges due to Lightning

To protect the devices from surge voltages due to lightening, it is
recommended to install surge-absorbing elements between the lines of
the input power and between one line and ground. This does not,
however, assure protection from all surges due to lightening.
The recommended items are as follows. (Items made by Okaya
Denki Sangyo Co.)

For the 200-V system

Between lines R⋅A⋅V-781BYZ-2

Between line and ground R⋅A⋅V-781BXZ-4

For the 400-V system

Between lines R⋅A⋅V-152BYZ-2A

Between line and ground R⋅A⋅V-801BXZ-4

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.

- 42 -

B-63943EN/02 3.INSTALLATION

Notes

(1) For a better surge absorbing effect, the wiring shown by heavy

line must be as short as possible.
Wire Size: The wire diameter must be 2 mm

greater.

Wire length: The sum of the length (a) of the wire for

the connection of surge-absorbing element
1 and that (b) of surge-absorbing element 2
must be 2 m or less.

(2) If conducting dielectric strength tests by applying overvoltages

(1000 VAC and 1500 VAC) to the power line, remove
surge-absorbing element 2. Otherwise, the overvoltages would
activate the element.

(3) The nonfuse breaker (5A) is required to protect the line when a

surge voltage exceeding the capacity of the surge-absorbing
elements is applied and the surge-absorbing elements are
short-circuited.

(4) Because no current flows through surge-absorbing elements 1

and 2 during normal operation, the nonfuse breaker (5A) can be
shared by other electric devices on the machine. It can be used
with the control power supply of the servo unit power supply
module or with the power supply for the fan motor of the spindle
motor.

The cabinet and pendant box that house a display and a operator's
panel that are to be designed and manufactured by the machine tool
builder are susceptible to dust, cutting debris, oil mist, etc. Note the
following and make sure that they are structured to prevent their entry.

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) Make sure that the display and operator's panel do not receive
cutting debris and coolant directly.

8) Oil can easily stay on the top of the cabinet and pendant box,
possibly dripping down the display and operator's panel. Make
sure that the cabinet and pendant box is of such a structure that
oil do not collect or that oil do not drip down the display or

4.2 TURNING ON AND OFF THE POWER TO THE CONTROL

UNIT

4.2.1 Power Supply for the Control Unit

Supply power (24VDC) to the control unit from an external sources.
Provide an ON/OFF circuit for turning the AC power on and off
outside the unit as shown in Fig. 4.2.1. To minimize the effect of
noise or voltage fluctuations to the CNC, it is recommended that a
power to the CNC be provided independently of the power sources to
devices with large noise or load fluctuations.
When the 30i series with PC functions is used, apply countermeasures
to guard against the possible destruction of hard disk storage due to
momentary power failure or power outage, by installing an
uninterruptible power supply, etc.
See Section 3.2 for power capacity.

4.2.2 External 24 VDC Power Specification and Circuit

Configuration

Specifications of recommended external 24 VDC power supply
(regulated power supply): (The power supply must satisfy UL1950.)
Output voltage:
+24 V ±10% (21.6 V to 26.4 V)
(including ripple voltage and noise. See the figure below.)
Output current:
The continuous load current must be larger than the current

consumption of the CNC.

(At the maximum temperature inside the power magnetics

cabinet in which the power supply is located)

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 (for -100%), 20 ms (for -50%)
Allowable 24-VDC instantaneous interruption time:

0.5 ms (lower than 21.6 V)

- Notes to take when the vertical axis exists

When the vertical axis exists, select the DC power supply that has a
long voltage hold time to decrease the amount of vertical axis falling
during power-off (including a power failure).
If the operating voltage drops to less than or equal to 21.6V, the CNC
releases servo activation. Therefore, when the hold time for 24 VDC
during AC power-off is too short, servo activation is released before
the breaks are applied because some peripheral circuit detects
power-off. This may increase the amount of vertical axis falling.
Generally, a power supply with sufficient power capacity tends to
increase the hold time during power-off.

- Circuit configurations

The following circuit configurations are not recommended.

For a circuit configuration in <2>, connect another regulated power
supply to be specifically used for the device with remarkable load
fluctuations so that the CNC and other units are not affected.
Avoid the use of a configuration in <2> if possible, even in an
environment with small load fluctuations or rush current. When two
or more units are connected to the same power supply, the 24-VDC
power may not be turned on due to a failure in a unit other than the
CNC. If this happens, it takes much time to locate the failure
because the CNC cannot start and no alarm indication is provided.
When the CNC and other units are connected to the same power
supply because of limited space for the power magnetics cabinet or for
some other reason, careful consideration must be given to possible
rush currents and voltage fluctuations. In addition, to prevent power
supply noise from entering the CNC, a noise filter must be inserted
before the power to the CNC. (Recommended noise filter:
ZGB2203-01U manufactured by TDK)

4.2.3 Power-on Sequence

Turn on the power to all the units at the same time, or in the following
sequence:

1 Power to the overall machine (200 VAC)
2 Servo amplifier control power supply (200 VAC)
3 Power to the slave I/O units connected via the I/O link, the separate

detector interface unit, and the stand-alone type LCD unit (24 VDC), power
to the CNC controller (24 VDC), power to the separate detector (scale)

As for a PANEL i, no specific power turn-on sequence for the CNC
control unit is required.

4.2.4 Power-off Sequence

Turn off the power to all the units at the same time, or in the following
sequence:

1 Power to the slave I/O units connected via the I/O link, the separate

detector interface unit, and the stand-alone type LCD unit (24 VDC), power
to the CNC controller (24 VDC)

2 Servo amplifier control power supply (200 VAC), power to the separate

detector (scale)

3 Power to the overall machine (200 VAC)

When turning off the power of the CNC controller, be sure to turn off
the power of units such as the slave I/O devices connected through I/O
Link, β amplifier with I/O Link, Power Mate and separate detector

- 55 -

4.POWER SUPPLY CONNECTION B-63943EN/02

interface unit, stand-alone type LCD unit, control power supply of the
servo amplifier, and separate detector (such as a scale).
As for a PANEL i, no specific power-off sequence for the CNC
control unit is required.

CAUTION

When the PANEL i is used, the OS must be shut

down before the power to the control unit is turned
off. Be careful not to turn off the power while the
hard disk is being accessed or before the OS has
terminated; otherwise, the hardware contents may
be destroyed.

When the power is turned off or when the power is momentarily
disconnected, processing must be performed from the machine as
necessary, because motor control is disabled.
For example, when movement along a vertical axis is controlled, a
brake should be applied to prevent falling. Usually, the brake clamps
the motor when the servo is not activated or when the motor is not
turning. The clamp is released only when the motor is turning.
When servo axis control is disabled by power-off or momentary
power disconnection, the brake usually clamps the servo motor. In
this case, before the relay for clamping operates, the controlled axis
may fall. So, also consider whether the distance the axis is likely to
fall will cause a problem.
When the power is turned off:
Be sure to apply a brake for clamping before turning off the

power to CNC.
When the power fails:
If a power failure is detected, a brake must be applied

immediately. Select the power supply with a longer DC power

retention time after AC power-off, because the servo is

deactivated if the power to CNC is turned off.

4.4 BATTERIES

In a system using this CNC, batteries are used as follows:

Use Component connected to battery

Memory backup in the CNC control
unit
BIOS data backup in the PANEL i PANEL i

Preservation of the current position
indicated by the separate absolute
pulse coder
Preservation of the current position
indicated by the absolute pulse
coder built into the motor

Used batteries must be discarded according to appropriate local
ordinances or rules. When discarding batteries, insulate them by
using tape and so forth to prevent the battery terminals from
short-circuiting.

4.4.1 Battery for Memory Backup in the CNC Control Unit (3 VDC)

Offset data, and system parameters are stored in SRAM memory
in the control unit. The power to the SRAM memory is backed up
by a lithium battery mounted on the front panel of the control unit.
The above data is not lost even when the main battery goes dead.
The backup battery is mounted on the control unit at shipping. This
battery can maintain the contents of memory for about a year.
When the voltage of the battery becomes low, alarm message "BAT"
blinks on the display and the battery alarm signal is output to the PMC.
When this alarm is displayed, replace the battery as soon as possible.
In general, the battery can be replaced within two or three weeks,
however, this depends on the system configuration.
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.

• Two alkaline dry cells (size D) in the external battery case.

NOTE

A lithium battery is installed as standard at the

factory.

4.4.2 Batteries for PANEL i (3VDC)

A lithium battery is used to back up BIOS data in the CNC display
unit with PC functions. This battery is factory-set in the PANEL i.
This battery has sufficient capacity to retain BIOS data for one year.
If the voltage of a battery drops, the following message is displayed
on the screen for a self-test performed immediately after power-on,
and the self-test pauses.
CMOS Battery Failure
**System Stopped by Temperature / Fan / Battery Alarm. Turn off the
Power. **
If this condition occurs, replace the battery as soon as possible (within
one week).
FANUC recommends that the battery be replaced once per year
regardless of whether a battery alarm is issued.

Replacing the battery

1 Obtain a new lithium battery (A02B-0200-K102).
2 After power has been supplied for at least five seconds, turn off

the power to PANEL i. Remove the intelligent terminal from

the panel so that replacement work can be done from the rear of

the intelligent terminal.

3 Detach the connector of the lithium battery, and remove the

battery from the battery holder.

4 Attach the connector, and place the battery in the battery holder.
5 Install PANEL i again.
6 Turn on the power, and check that the BIOS data are maintained

(no error message is output at start-up).

NOTE

Between removing an old battery and inserting new

battery, no more than five minutes must be allowed
to elapse.

The BIOS data is usually preserved as long as the battery is replaced
according to the above procedure. If the data is lost, the following
error message is displayed when the power is turned on:

4.4.3 Battery for Separate Absolute Pulse Coders (6VDC)

(1) When the voltage of the battery for absolute pulse coders

becomes low, DS alarms 306 to 308 occur.

(2) When DS 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 pulse coders used.

(3) If the voltage of the battery becomes any lower, DS alarm 306

(battery zero alarm) occurs. In this case, the current positions

for the pulse coders can no longer be maintained.

In this state, DS alarm 300 (reference position return request

alarm) occurs. Return the tool to the reference position after

replacing the battery.

(4) The service life of the batteries is about two years if they are

used in a six-axis configuration with αi/αis/βis series servo

motors and one year if they are used in a six-axis configuration

with α/β series servo motors. FANUC recommends that you

replace the batteries periodically according to the battery service

life.

(5) To connect the battery, use the battery case or incorporate the

battery into the servo amplifier. Note that the attachment

method of the battery depends on the connection method and the

type of servo amplifier.

B-63943EN/02 4.POWER SUPPLY CONNECTION

Replacing batteries

To prevent absolute position information in absolute pulse coders
from being lost, turn on the machine power before replacing the
battery. The replacement procedure is described below. (Note:
The turning-on step is not required when the αi or αis series servo

motor or βis series servo motor (β0.4is to β22is) is used.)
(1) Turn the servo amplifier on.
(2) Place the machine in the emergency stop state.
(3) Confirm that servo motors are not active.
(4) Make sure the DC link charge LED is off.
(5) Remove the old battery and then attach a new one.
(6) Now, replacement has been completed. The system power can

be turned off.

NOTE

The absolute pulse coder of the αi/αis/βis (β0.4is to

β22is) 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. If battery
replacement takes 10 minutes or more, the power
must remain turned on.

CAUTION

1 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.

2 Before replacing the battery, make sure the DC link

charge LED is off. Otherwise, an electric shock may
be received.

3 Be sure to use the specified battery. If another type

of battery is used, it may overheat, blow out, or catch
fire.

4 Install the battery with correct polarity. If the battery

is installed with incorrect polarity, it may overheat,
blow out, or catch fire. Or, absolute position
information in absolute pulse coders may be lost.

5 During attachment of the battery, insert the

factory-attached protection socket into the CX5X or
CX5Y connector, whichever is not used. If the +6 V
pin and 0 V pin are short-circuited, the battery may
overheat, blow out, or catch fire. Or, absolute

5.3 CONNECTION WITH INPUT/OUTPUT DEVICES

5.3.1 Overview

An input/output device is used to enter information such as CNC
programs and parameters from an external device to the CNC, or to
output information from the CNC to an external device.
The input/output devices usable with this CNC include Handy File.
The interface of the input/output devices electrically conforms to
RS-232-C, so that a connection can be made with a device that has an
RS-232-C interface.
The tables below indicate the serial ports of this CNC.
See Chapter 13, when an PANEL i is used.
