3.INSTALLATION B-64303EN/03

Normal machine factory environment (take protective measures when

Atmosphere outside the cabinet the control unit is used in an environment where the concentration of
dust, coolant, organic solvent, corrosive gas is relatively high.)

NOTE
1 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:
58°C－(1750-1000)/100×1.0°C＝50.5°C
Therefore, the allowable ambient temperature range is from 0°C to 50.5°C.
2 When using a unit for which the installation conditions are specified separately,
the conditions also need to be met.

3.2 POWER SUPPLY CAPACITY

3.2.1 Power Supply Capacities of CNC-related Units

The following CNC-related units require an input power supply that satisfies the indicated current
capacities with a power supply voltage of 24 VDC ±10%. Here, note that momentary voltage changes
and ripples are also within ±10% of the power supply voltage.

Table 3.2.1 (a) Power supply capacity

Unit Power supply capacity Remarks
Control unit With no-optional slot 1.5A Note 1)

NOTE
1 The liquid-crystal display and MDI unit are included. Optional boards are not
included.
2 When connecting an RS-232-C unit (powered by the NC) to the RS-232-C port,
add the current capacity of the unit. Up to 1 A can be supplied from the two
channels of the port.
3 Use memory cards that consume no more than 2 W.
4 For other peripheral units (such as I/O units), see Table 3.2.1 (b) and also refer
to the relevant manuals.
5 When you select the input DC power supply for the CNC control section,
consider the restrictions other than the power supply capacity. Be sure to see
also Subsection 4.2.2.

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 installation conditions of the I/O unit and connector panel I/O module must be satisfied.
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

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 1m2 surface area, that is,
when the 6W heat source is contained in a cabinet having a surface area of 1 m2, 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.
In the case of the operator's panel cabinet for example, to limit the temperature within the operator's panel
cabinet to 58°C or less when the ambient temperature is 45°C, satisfy the following expression.
Internal heat loss P [W] ≤
6[W/m2⋅°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 3.4.4, may be used.)
For example, a cabinet having a surface area of 4m2 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 or more.
When this happens, the cooling capacity of the cabinet must be improved using the heat exchanger.
In the case of the power magnetics cabinet for housing cabinet the I/O unit for 0i, limit the internal
temperature increase to 10°C or less, not 13°C or less.

3.4.3 Thermal Design of Operator's Panel

With a small cabinet like the operator's panel, the heat dissipating capacity of the cabinet is as shown
below, assuming that there is sufficient mixing of the air inside the cabinet.
Coated metal surfaces: 8 W/m2°C
Plastic surfaces: 3.7 W/m2°C

An example of the thermal design for the cabinet shown in Fig. 3.4.3 is shown below.

- 13 -
3.INSTALLATION B-64303EN/03

Fig. 3.4.3

Assume the following.

Thermal exchange rates
Coated metal surfaces : 8 W/m2⋅°C
Plastic surfaces : 3.7 W/m2⋅°C
Allowable temperature rise : 13°C higher than the exterior temperature
Also, assume the following.
Dimensions of pendant type cabinet shown in Fig. 3.4.3 : 560(W) × 470(H) × 150(D) mm
Surface area of metallic sections : 0.5722 m2
Surface area of plastic sections : 0.2632 m2

In this case, the allowable total heat dissipation for the cabinet is:
8 × 0.5722 × 13 + 3.7 × 0.2632 × 13 = 72 W.

In consequence, it can be concluded that the units shown in Table 3.4.3 on the next page can be installed
in this cabinet.

3.5 COUNTERMEASURES 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 Grounding
Grounding the power magnetics cabinet and devices is very important to prevent an electric shock and
suppress a noise influence. The following describes the grounding methods for suppressing the noise
influence.

3.5.1.1 About grounding types

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.

3.5.1.2 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.

(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 3.5.1.4 for the cabinet. Fig. 3.5.1.2 (a) is a schematic wiring diagram.
When the multipoint grounding scheme is adopted, the units can be grounded at low impedance, and
ground wires can be shortened, so that wiring may be simplified.

- 15 -
3.INSTALLATION B-64303EN/03

(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. 3.5.1.2 (b) is a schematic wiring diagram.

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.

3.5.1.3 Cable clamp and shield processing

Signal lines basically require shield clamps. The influence of external noise can be suppressed by
properly providing the signal lines with the shield clamps.
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.)
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.

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 a malfunction due to a failure or noise.

3.5.1.4 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.

(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.

- 21 -
3.INSTALLATION B-64303EN/03

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 Bring the m etal plates into direct contact with each
other, without applying a coating to their joint areas.

NOTE
For improved noise immunity, how to provide low-impedance electrical continuity
in the cabinet is described here. To construct a protective circuit, a protective
grounding connection must be made between the metal plates by using electric
wires with a cross-sectional area appropriate for the AC input power capacity of
the unit mounted on each metal plate.

(2) Mounting units on the cabinet

The shortest possible lengths of unit ground wires 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.

3.5.4 Noise Suppressor

The AC/DC solenoid, AC/DC relay, and other devices 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 is induced through a cable or any other component, causing the electronic circuits to be
disturbed.
Take the following measures against the pulse voltage:
1) See Subsection 3.5.3 for groups A and B, and use spark killers for AC circuits or diodes for DC
circuits.
2) See “Notes on selecting the spark killer” below for information about selection of spark killers or
diodes.

Notes on selecting the spark killer

• Use a CR–type spark killer. (Use it for AC circuits.)
(A varistor is useful in clamping the peak pulse voltage, but cannot suppress the sudden rise of the
pulse voltage. FANUC therefore recommends the use of a CR–type spark killer.)
• The reference CR values of the spark killer shall conform to the following based on the current ((I
(A)) and DC resistance of the coil in the stationary state:
1) Resistance (R) : Equivalent of the DC resistance of the coil
I2 I2
2) Capacitance (C) : ~ (μF)

3.7 SEVERE DUST/LIQUID PROTECTION OF CABINETS AND

PENDANT BOXES
Since a cabinet or pendant box, which is designed by the machine tool builder, for housing display units
or operator's panels is likely to receive dust particles, chippings, or greasy fumes, so keep the following in
mind to keep them out.
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.
Apply packing to the panel mounting surfaces of other units mounted on the same case for
dust/liquid protection.
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.

- 30 -
B-64303EN/03 3.INSTALLATION
8) Since coolant accumulated on the top of a cabinet or pendant box may drip onto the panel surface of
a display unit of operator's panel, use a structure that prevents coolant from being accumulating on
the top or from being dripping onto the panel surface. For example, install a canopy over a display
unit or operator's panel.
9) The front surface of a display unit must be vertical. Otherwise, coolant is likely to accumulate in
the lower part of the display screen.

Provide an ON/OFF circuit for turning the AC power on and off outside the unit as shown in Fig. 4.2.1.

other factors.
Instantaneous input interruption retention time:
10 ms (for -100%), 20 ms (for -50%)

Fig 4.2.2 (a) Timing chart

- 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.

The following circuit configurations are not recommended.

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

The power to the CNC must not be turned on or off with the power to units on.

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)

“Turning on the power to all the units at the same time” means completing the power–on operations in 1
and 2 above within 500 ms of performing power–on in 3.
Do not remove the memory backup battery (3VDC) and the separate absolute pulse coder battery (6VDC)
regardless of whether the power of the CNC controller is on or off. If the batteries are removed when
the CNC controller is off, the parameters and programs saved in the CNC controller and the position data
in the pulse coder are lost.
For information on replacing the memory backup battery, see Subsection 4.4.1.

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 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
interface unit, control power supply of the servo amplifier, and separate detector (such as a scale).
“Turning off the power to all units at the same time” means completing the power–off operations in 2 and
3 above within 500 ms before the power–off operation described in 1 above. If the power to the units
indicated in 2 or 3 is turned off other than within 500 ms of the power in 1 being turned off, alarm
information is left in the NC.
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.

- 36 -
B-64303EN/03 4.POWER SUPPLY CONNECTION
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 CNC control unit
Preservation of the current position indicated by the Separate detector interface unit
separate absolute pulse coder
Preservation of the current position indicated by the Servo amplifier
absolute pulse coder built into the motor

4.4.1 Battery for Memory Backup in the CNC Control Unit (3 VDC)
Offset data, and system parameters are stored in SRAM in the control unit. The power to the SRAM 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.
- 37 -
4.POWER SUPPLY CONNECTION B-64303EN/03

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.

When a lithium battery is used

- Replacement procedure
Prepare a new battery unit (ordering code: A02B–0309–K102).
(1) Turn on the power to the CNC. After about 30 seconds, turn off the power.
(2) Extract the old battery unit from the lower right of the rear of the CNC unit. (Hold the latch of the
battery unit, and extract the unit upward while releasing the claw from the case.)

Extract the unit while holding this portion.

(3) Mount the new battery unit. (Push the battery unit in until the claw is latched into the case.) Ensure
that the latch is engaged securely.

- 38 -
B-64303EN/03 4.POWER SUPPLY CONNECTION

Push the unit in until the claw is

latched into the case.

WARNING
Using other than the recommended battery may result in the battery exploding.
Replace the battery only with the specified battery (A02B-0309-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 memory may be lost.
If steps 1 to 3 may not be completed within 30 minutes, save all contents of the
SRAM memory to the memory card beforehand. Thus, if the contents of the
SRAM memory are lost, the contents can be restored easily.

When discarding a battery, observe the applicable ordinances or other rules of your local government.
In addition, cover the exposed pins with tape or other insulation materials to prevent a short circuit before
discarding the battery.

When using commercial alkaline dry cells (size D)

To use commercial alkaline dry cells (size D) instead of the lithium battery attached to the control unit,
install the battery unit in other than the control unit.

- Connection method
Remove the factory-mounted lithium battery from the control unit as described in the battery replacement
method above. Connect the battery cable (A02B-0309-K103) to the battery case (A02B-0236-C282). This
battery cable has the same connector as the lithium battery unit, so connect the connector to the place
where the lithium battery unit was installed as shown in the figure below. Since the connector has a
simple lock system, make sure that the lock is applied during installation.

- 39 -
4.POWER SUPPLY CONNECTION B-64303EN/03

NOTE
1 The battery case (A02B-0236-C282) needs to be installed in a position
where dry cells can be replaced even when the control unit is powered on.
2 The connector part of this battery cable engages with a simple lock system.
Therefore, fix a cable portion up to 500mm long from the connector side
without the portion being yanked to prevent the connector being removed by
the cable weight or tensile stress.

- 40 -
B-64303EN/03 4.POWER SUPPLY CONNECTION

Replacing the alkaline dry cells (size D)

- Replacing the battery
(1) Prepare two new alkaline dry cells (size D).
(2) Turn on the power of the control unit.
(3) Remove the battery case cover.
(5) Replace the batteries, paying careful attention to their orientation.
(6) Replace the battery case cover.

CAUTION
To replace the battery when the power is off, follow the same procedure as that
for the replacement of a lithium battery, described above.

4.4.2 Battery for Separate Absolute Pulsecoders (6VDC)

The current position data of the absolute pulse coder connected to the separate detector interface unit is
saved by the battery connected to connector JA4A of the separate detector interface unit.
If the voltage of the battery drops, DS alarms 306 to 308 are issued. When DS alarm 307 (battery
voltage drop alarm) occurs, replace the battery as soon as possible. Estimated time to run out of the
battery is 1 to 2 weeks, but the actual life depends on the number of pulse coders.
If the voltage of the battery further drops, DS alarms 306 (battery zero alarm) occurs. In this case, the
current position of the pulse coder cannot be recorded and DS alarm 300 (reference position return alarm)
occurs. Replace the battery and perform a reference position return.
Although the battery life depends on the number of pulse coders connected, it is recommended that the
battery be replaced annually regardless of the issuance of the above alarms.

Replacing a battery
Obtain four commercially available alkaline batteries (size D).
(1) Turn on the power of the machine (CNC).
(2) Loosen the screws of the battery case, and remove the cover.
(3) Replace the dry batteries in the case.
Screws

Cover

(4) After installing the new batteries, replace the cover.

(5) Turn off the power to the machine (CNC).

WARNING
If the batteries are installed incorrectly, an explosion may occur. Never use
batteries other than the specified type (Size D alkaline batteries).

CAUTION
The battery must be replaced with the power of the CNC turned on (the servo
amplifier turned on).
Note that, if batteries are replaced while no power is supplied to the CNC, the
recorded absolute position is lost.

4.4.3 Battery for Absolute Pulsecoder Built into the Motor (6VDC)
The battery for the absolute pulse coder built into the motor is installed in the servo amplifier. For the
methods of connection and replacement, refer to the maintenance manual of your servo amplifier.

Condition2 EIA code CR is LF in ISO code.
Condition3 EIA code O is : in ISO code.
2 Control codes DC1 to DC4 are transmission codes output from the NC.
So they need not to be punched on the NC tape.

(3) Transmission rate (Baud rate)

The transmission rate (Baud rate) is the number of bits transferred per second.
The following baud rates are available depending on the system parameter.
50, 100, 110, 150, 200, 300, 600, 1200, 2400, 4800, 9600, 19200

[Example]
Baud rate : 110
When using one start bit and two stop bits (totalling 11 bits per character):
Transmission characters/second= 110/11
=10 characters/second (Max.)
(4) Cable length
The cable length depends on the external device type. Consult with the device manufacturers for
actual connecting cable lengths.
Cable length is as follows by the specification of NC.

2 The high-speed skip signal is assumed to be 1 when the input voltage is at the
low level and 0 when it is at the high level.
3 The input level for the CNC receiver is high when the circuit is open. So, the
input level for the external driver must be low.

5.4 LINKING THE EMBEDDED ETHERNET INTERFACE

CAUTION
Before attaching or removing cables, power off the CNC main unit, and confirm
that the power is off.
Ask the respective manufacturers for explanations about how to build a network
and about conditions for using units (such as a media converter, hub,
transceiver, and cable) other than the CNC unit. When installing network
cables, exercise sufficient caution so that the network will not be affected by any
noise source. Electrically separate the network wiring sufficiently from noise
sources like motors and their power lines. Also, ground each unit as required.
If the grounding impedance is high, it may cause trouble in communication.
Once the equipment is installed, conduct communication tests to verify normal
operation before starting actual use of the equipment.
FANUC is not liable to any damage related to trouble arising from any unit other
than the CNC unit.

5.4.1 Connection to the Ethernet Interface

The 100BASE-TX interface are available. A hub (line concentrator) is used to connect the CNC unit to
a system. A typical connection example is shown below.

HUB
(line concentrator)

NOTE
1 To make a connection to the 10BASE-T Ethernet, use a hub that meets the
following conditions.
• Compliant with 100BASE-TX
• With the auto-negotiation function
• Support for the store & forward system
2 Some of the units (hub, transceiver, etc.) required to build a network are not
dust-proof/water-proof (oil-proof). Using them in an atmosphere with dust or oil
mist may lead to a communication error or failure. They should be enclosed in a
dust-proof/water-proof (oil-proof) cabinet.

Leading in Ethernet cables

An Ethernet cable should be fixed with a clamp or the like so that pulling it will not cause tension to be
applied to the connector (RJ-45) at the end of the cable. The clamp not only fixes the cable but also
grounds the shield of the cable.

NOTE
The cable can be up to 100 m long (for the FANUC- recommended cable for
movable sections, up to 50 m). Do not make the cable longer than necessary.

Cable Wires
Many cables without a shield (UTP cables) are commercially available as twisted pair cables conforming
to 10BASE-T or 100BASE-TX. To improve noise immunity in factory automation environments,
however, be sure to use twisted pair cables (STP cables) with a common shield in category 5.

5.4.3 Anti-Noise Measure

Separating signal lines
Ethernet cable wires belong to group C. See descriptions elsewhere for explanations about how to
separate them from wires in group A or B.

Cable clamp and shield processing

If any cable led into the CNC requires shielding, clamp it as shown below. The same method is used
also to shield Ethernet twisted-pair cables. The clamp shown in the figure works not only for cable
fixing but also for shield processing. Shield processing is very important to maintain the stable
operation of the system. Do not forget attach this clamp. See Subsection 3.5.1.3 "Cable Clamp and
Shield Processing," for details.

5.4.4 Network Installation

Even when the machine satisfies its grounding requirements, noise from the machine may get on
communication lines depending on the way the machine is installed and its environment, resulting in a
communication error. Separating and isolating the Ethernet backbone cable and PC from the machine
can prevent noise from getting on the communication lines.
An example of connection is shown below.

- 66 -
B-64303EN/03 5.CONNECTION TO CNC PERIPHERALS

NOTE
1 Ground the PC and backbone cable separately from the machine system.
If this is impossible because there is only one grounding point, use separate
grounding wires for the PC/backbone cable and the machine system up to the
grounding point.
The grounding resistance must not be higher than 100 Ω (class 3 grounding).
The grounding wire must not be thinner than the AC power line conductor, and
its cross-sectional area must not smaller than 5.5 mm2.
2 In some cases, the aforementioned isolation/separation method based on
100BASE-TX cannot assure normal communication because of influence by
noise. In such worst environments, use optical fiber media to completely isolate
the machine from the PC.

5.5.1 Connection of the LCD Unit with a Touch Panel

When the LCD unit with a touch panel is used, RS232C serial port 2CH (JD36B) cannot be used as a
general-purpose port because it is used for touch panel communication. Since the touch panel
communication cable is routed before shipment from FANUC, the tool builder does not need to route it.

6.1.1 Connection of One to Two Serial Spindles

When connecting one serial spindle amplifier, connect it to JA41. When connecting a second serial
spindle amplifier, connect it to JA7A of the first serial spindle amplifier.
Electric cables are usually used to connect serial spindles, but optical fiber cables and optical adapters
need to be used when:
- The cable length is 20 m or more.
- A ground wire with a cross-sectional area of 5.5 mm2 or more cannot be used to connect between
the power magnetics cabinet having spindle amplifiers installed and the operator's panel cabinet
having the CNC control unit installed.
- Cables may be significantly affected by noise. For example, when there is a strong electromagnetic
noise generator such as a welding machine near the cables or when the cables runs long in parallel
with a power line that generates noise or a power magnetic cable
NOTE
The conventional optical I/O Link adapter (A13B-0154-B001) cannot be used.
Use optical adapter (A13B-0154-B003).

Conditions for installing the serial spindle connector panel

• The serial spindle connector panel does not have an enclosed structure. So, install the serial spindle
connector panel in an enclosed cabinet as used for the CNC.
• Ground the case by using the case mounting screws of the serial spindle connector panel.
• The serial spindle connector panel is light, so that it need not be secured with screws. However,
ensure that the serial spindle connector panel does not contact other electrical circuits and thus cause
a short circuit. When securing the serial spindle connector panel to the cabinet, for example, attach
an L-shaped metal fitting as shown below with a case mounting screw (M3) of the serial spindle
connector panel.

When a separate detector such as a separate rotary encoder or linear encoder is used, a separate detector
interface unit is required. The separate detector interface unit is connected through an optical fiber cable
as an unit on an FSSB line.
A separate detector interface unit consists of basic units and additional units. Up to four pulse coders or
liner scales can be connected by adding an additional unit (up to eight units can be connected as a total).
An additional unit is connected to a basic unit through a flat cable. The maximum number of separate
detector interface units that can be connected to an FSSB line is two for HRV2 and HRV3.

NOTE
1 Unused optical connectors must be covered with the caps.
2 When using an encoder with an analog output of 1 Vp-p, see the description of
the analog input separate detector interface.

Recommended cable specification: A02B-0124-K830 (5 m)

(The external power supply end of the cable is provided with M3 crimp terminals.)

The 24 VDC input to CP11A can be output at CP11B for use in branching. The connection of CP11B is
identical to that of CP11A. In this case, the power supplied to CP11A should be equal to the sum of the
rating of the separate detector interface unit and that of the units after CP11B.

Be sure to ground the 0-V line of the power supply to the separate detector interface unit. In addition,
keep any noise source (such as an AC power cable and contactor) away from the power line of the
separate detector interface unit as far as possible to prevent noise from being picked up through the power
line.

Secure the ground line to the ground terminal (GND) for signals of a separate detector interface unit,
which is located at the bottom of the unit, with an M3 screw as shown in the figure below. Connect the
ground line to the ground plate of the cabinet.

7.2.5 Input Signal Requirements (Parallel interface)

The feedback signals from the separate detectors connected via the parallel interface are defined as
follows:

(1) A and B phase signal input

This is a method to input position information by the mutual 90 degree phase slip of A and B phase
signals.
Detection of the position is performed with the state in which the B phase is leading taken as a shift
in the plus direction, and the state in which the A phase is leading as a shift in the minus direction.

Time requirements
Requirements for the signals at the input pins of input connectors JF101 to JF108. The signals for these
connectors are differential input signals with A and B phases. An important factor is time TD from
point A, when the potential difference between PCA and *PCA exceeds 0.5V, to point B, when the
potential difference between PCB and *PCB becomes lower than 0.5V. The minimum value of TD is
0.15msec. The period and pulse width of the signals must be long enough to satisfy the above
requirements.

The Z phase signal is also a differential signal. The following conditions are stipulated for the time from
when the potential difference between PCZ and *PCZ exceeds 0.5 V to when the potential difference
becomes lower than 0.5 V.

Tw ≥ 1/4 frequency of A phase or B phase

TOFF > 1.5 msec

Input voltage requirements

The voltage of the A and B phase signals must meet the following requirements:
High level: 2.4 V or more
Low level: 0.8 V or less

Rotation directions of a servo motor and separate rotary encoder

If a separate rotary encoder rotates in a direction opposite to the direction of servo motor rotation when
the servo motor is rotating, the connection of the feedback cable from the separate rotary encoder must be
changed as follows:
(1) Exchange signal PCA with signal PCB.
(2) Exchange signal *PCA with signal *PCB.

7.2.10 Notes on Installing a Separate Detector Interface Unit

CAUTION
To install/remove the unit, a screwdriver must be inserted obliquely. So,
sufficient access clearances are required on both sides of the unit. As a
guideline, if the front of an adjacent unit appears flush with the unit or slightly set
back, allow a clearance of about 20 mm between the unit and the adjacent unit.
If the front of an adjacent unit protrudes beyond the front of the unit, allow a
clearance of about 70 mm between the unit and the adjacent unit. Also, when
installing the unit near a side of the cabinet, allow a clearance of about 70 mm
between the unit and the side of the cabinet.

7.3.1 Overview
When a separate detector such as a rotary encoder or linear encoder with an analog output of 1 Vp-p is
used, an analog input separate detector interface unit is used. The analog input separate detector unit is
connected via an optical cable as a unit on the FSSB line. Up to four 1-Vp-p output separate detectors
can be connected to a basic unit.
One additional unit (A02B-0236-C204) can be connected to the basic unit with a flat cable. Four
separate detectors with digital output can be connected to the additional unit. When five or more 1-Vp-p
output separate detectors are to be used, more than one basic unit (analog input separate detector interface
unit) is required. The JA4A connector is provided for the battery for absolute position detectors
connected to the additional unit.
The maximum number of separate detector interface units that can be connected to one FSSB line is two
for HRV2 and HRV3, regardless of which input type, the analog input type or digital input type, is used.

NOTE
1 Unused optical connectors must be covered with the caps.
2 A digital output encoder refers to an encoder that outputs A and B rectangular
waveforms (parallel) or a FANUC serial interface output encoder (serial).
3 No 1-Vp-p output encoder can be connected to additional units.

the external power supply.

Recommended cable specification: A02B-0124-K830 (5 m)

(The external power supply end of the cable is provided with M3 crimp terminals.)

The 24 VDC input to CP11A can be output at CP11B for use in branching. The connection of CP11B is
identical to that of CP11A. In this case, the power supplied to CP11A should be equal to the sum of the
rating of the analog input separate detector interface unit and that of the units after CP11B.

Be sure to ground the 0-V line of the power supply to the analog input separate detector interface unit.
In addition, keep any noise source (such as an AC power cable and contactor) away from the power line
of the analog input separate detector interface unit as far as possible to prevent noise from being picked
up through the power line.

Secure the ground line to the ground terminal (GND) for signals of an analog input separate detector
interface unit, which is located at the bottom of the unit, with an M3 screw as shown in the figure below.
Connect the ground line to the ground plate of the cabinet.

NOTE
If the cable is connected to JA4A when the separate absolute pulse coder
battery case contains the battery, the battery voltage is applied to the battery
power supply pin (+6 V) for each of the feedback connectors (JF105 to JF108).
In this case, if the battery line and 0 V are short-circuited, the battery may heat
up or the protection circuit within the separate detector interface unit may fail.
First, make sure the battery case contains no battery or the cable is not
connected to JA4A. Then, complete all cabling work and confirm cables are
correctly connected. Finally, place the battery or connect the cable to JA4A.

7.3.10 Notes on Installing an Analog Input Separate Detector

Interface Unit
CAUTION
To install/remove the unit, a screwdriver must be inserted obliquely. So,
sufficient access clearances are required on both sides of the unit. As a
guideline, if the front of an adjacent unit appears flush with the unit or slightly set
back, allow a clearance of about 20 mm between the unit and the adjacent unit.
If the front of an adjacent unit protrudes beyond the front of the unit, allow a
clearance of about 70 mm between the unit and the adjacent unit. Also, when
installing the unit near a side of the cabinet, allow a clearance of about 70 mm
between the unit and the side of the cabinet.

8 CONNECTION TO FANUC I/O Link

WARNING
There is a possibility that I/O Link slave module will not operate normally due to
a failure of CNC or I/O module, or abnormally power supply voltage. To prevent
accidents even in this case, design the machine to operate safely by making a
safety circuit outside the I/O Link slave module.

8.1 OVERVIEW
FANUC I/O Link is a serial interface that has a CNC, a cell controller, various I/O units, the machine
operator's panel, or the Power Mate connected and receives or sends I/O signals (bit data) at high speed
between the devices. The FANUC I/O Link regards one device as the master and other devices as slaves
when more than one device is connected. Input signals from the slaves are sent to the master at specified
intervals. Output signals from the master are also sent to the slaves at specified intervals.

8.2 CONNECTION
The I/O Link interface connector JD51A is provided on the main board.
In the I/O there are the master station and its slave stations. The master is the control unit of the CNC,
and the slave is the I/O unit-A. The slaves are divided into groups, and up to 16 groups can be
connected to one I/O Link. (For the Series 0i Mate, however, the number of I/O points are limited.)
The I/O Link is connected in different ways depending on the types of units actually used and the I/O
points. To connect the I/O Link, the assignment and addresses of the I/O signals have been made
programmable with the PMC program. The total number of I/O points for each channel of I/O Link is
1024 or less.
There are two I/O Link connectors: JD1A and JD1B. These connectors are provided for all units that have
the I/O Link function. A cable must be connected from JD1A to JD1B. Although JD1A of the last unit
is not used and left open, it need not be connected with a terminator.
The pin assignments of connectors JD1A and JD1B are common to all units on the I/O Link, and are
illustrated on Subsec. 8.2.1. Use the figures when connecting the I/O Link irrespective of the type of
unit.

8.2.1 Connection of FANUC I/O Link by Electric Cable

+5 V terminals are for an optical I/O Link adapter. They are not necessary when connecting with a
metal cable.
A line for the +5V terminal is not required when the Optical I/O Link Adapter is not used.
No connections must be made to the pins with brackets ([ ]) because they are used in JD51A when the
second channels are connected in the FANUC I/O Link.
Do not make a connection to a pin for which no signal is assigned.

9.2.4 DI/DO Connector Pin Assignment

This section describes the DI/DO connector pin allocation of the basic module and expansion modules A
and B.

NOTE
1 The DI and DO addresses for the basic and expansion modules run
contiguously. These basic and expansion module DI and DO addresses are
allocated to the I/O Link as a group. For example, when the DI and DO top
addresses are X0004 and Y0000 (m = 4 and n = 0), respectively, then the
addresses are allocated as shown in the following table.
2 Pins 18 and 50 (+24V) of connector CB150 are used to apply 24 V externally to
a module. Be sure to connect these pins because the +24 V applied to the
module is used internally.

NOTE
Xm+0.0 through Xm+0.7 are DI pins for which a common voltage can be
selected. That is, by connecting the DICOM0 CB150(24) pin to the +24 V power
supply, a DI signal can be input with its logical state reversed. If, however, a
cable is connected to ground, it has the same effect as inputting an ON state DI
signal. To prevent such accidents, the connection of the DICOM0 CB150(24) pin
to the 0 V power supply is recommended whereever possible.
For safety reasons, the emergency stop signal needs to be allocated to an
appropriate bit of the addresses for which the common voltage is fixed, ranging
from Xm+1.0 to Xm+1.7 or from Xm+2.0 to Xm+2.7. See Subsection 8.4.19 for
information about how to allocate the emergency stop signal.
For unused DI pins allocated to the addresses for which the common voltage is
fixed (fromXm+1.0 to Xm+1.7 and from Xm+2.0 to Xm+2.7), the logic is fixed to
“0”. For unused pins allocated to Xm+0.0 to Xm+0.7 for which the common
voltage can be selected, the logic is fixed to “0” when the DICOM0 CB150(24)
pin is connected to the 0 V power supply. When the DICOM0 CB150(24) pin is
connected to the +24 V power supply, the logic is fixed to “1”. The logic of the
unused pins allocated to Xm+0.0 to Xm+0.7 is variable when the contact of the
DICOM0 CB150(24) pin is open.

NOTE
When DO is on in the sequence, the ON/OFF state of DOCOM is directly
reflected in the DO state as indicated above by the dashed box. The +24 V
signal to be supplied to the I/O module must not be turned off during operation.
Otherwise, a CNC communication alarm is issued. Ensure that +24 V is supplied
either when or before the power to the CNC is turned on, and that +24 V is
removed either when or after the power to the CNC is turned off.

Parallel DO (output signal) connection

A DO load current of twice the level can be obtained by connecting DO points in parallel and exercising
ON/OFF control at the same time in the sequence. Namely, the maximum load current per DO point is
200 mA.
By connecting two DO points in parallel and turning on the two DO points at the same time, 400 mA can
be obtained. In this case, however, the leakage current is doubled up to 40 µA when the DO points are
turned off.

means that the channel to be used can be dynamically selected by the ladder.
The channel switching DO point for channel selection is included in the two–byte
occupied output points.

9.2.14 Analog Input Specifications

(Digital output)
This digital input module has four input channels. The digital output section consists of a group of 12 bits
within the three–byte occupied input points. The output format is indicated below.
Address in the module 7 6 5 4 3 2 1 0
Xm(even–numbered address) D07 D06 D05 D04 D03 D02 D01 D00
Xm+1(odd–numbered address) 0 0 CHB CHA D11 D10 D09 D08

D00 to D11 represent 12–bit digital output data. D00 and D11 correspond to weightings of 20 and 211,
respectively.
D11 is a sign bit expressed as a two’s complement. CHA and CHB represent analog input channels.
This means that when the two bytes above are read with a PMC program, the A–D converted data of the
CHA and CHB input channels can be read from D11 to D00. For CHA and CHB, see the description of
channel selection, below.
When data is read with a PMC program, some notes need to be observed. See "(Address allocation)" on
the next page.

9.CONNECTION OF I/O Link SLAVE DEVICES B-64303EN/03

(Channel selection)
With this analog input module, which of the four channels is to be output to the digital output section
must be determined with a PMC program.
The DO points used for this selection are CHA and CHB (two–byte occupied output points). These are
mapped as indicated below.
Address in the module 7 6 5 4 3 2 1 0
Yn X X X X X X X X
Yn+1 X X X X X X CHB CHA

By writing the values indicated below to CHA and CHB, the corresponding channel is selected, and the
A–D converted data of the channel and the data of the selected channel can be read as DI data. The
character X indicated above represents an unused bit, so that either 1 or 0 may be written in place of X.
CHB CHA Channel selected
0 0 Channel 1
0 1 Channel 2
1 0 Channel 3
1 1 Channel 4
Immediately after channel switching, some time is required until the channel is switched to the selected
one and A-D converted data is enabled. Be sure to confirm the channel before obtaining A-D converted
data.

9.2.15 Manual Pulse Generator Connection

An example in which three manual pulse generators are connected to expansion module A is shown
below.

Recommended wire material:

A66L-0001-0286 (#20AWG×6+#24AWG×3 pairs)
Recommended connector:
A02B-0120-K303 (including the following connector and case)
(Connector: Hirose Electric Co., Ltd. FI40-2015S, soldering type)
(Case: Hirose Electric Co., Ltd. FI40-20-CV5)
Recommended cables:
A02B-0120-K841 (7m) (for connecting three manual pulse generators)
A02B-0120-K848 (7m) (for connecting two manual pulse generators)
A02B-0120-K847 (7m) (for connecting one manual pulse generator)
(These cables do not include the wire shown in the above figure.)

NOTE
The number of connectable manual pulse generators depends on the type and
option configuration.

9.CONNECTION OF I/O Link SLAVE DEVICES B-64303EN/03

9.2.16 Cable Length for Manual Pulse Generator

Like a pulse coder, the manual pulse generator operates on 5 VDC. The supply voltage drop due to the
cable resistance must be held below 0.2 V (when those of the 0–volt and 5–volt wires are combined), as
expressed in the following expression:

0.1×R×2L Where 0.1 : Manual pulse generator supply current [0.1 A]

0.2≥
m R : Resistance per unit cable length [μ/m]
m : Number of 0–volt and 5–volt wires
L : Cable length [m].

m
L≤
R

Therefore, the cable length can be determined using the following expression.
In the case of the A66L–0001–0286 cable, for example, when three pairs of signal wires and six power
supply wires (20/0.18, 0.0394 Ω/m) are used (three power supply wires connected to 5 V and the other
three to 0 V), the cable length is:
3
L≤ =76.75[m]
0.0394

However, the maximum pulse transmission distance for the manual pulse generator is 50 m. Taking this
into consideration, the cable length may be extended to:
38.37 m (when two generators are used), or
25.58 m (when three generators are used).

9.2.17 Connection of Basic and Expansion Modules

Modules can be connected in the same way, regardless of whether you are connecting the basic module to
an expansion module or connecting two expansion modules. Connect the modules by using 34–pin flat
cable connectors as shown in the figure below. Ensure that all 34 pins at one end of the cable are
connected to the corresponding pins at the other end;
e.g., connect the A1 pin to the pin having the same designation (A1) at the other end.

- 142 -
B-64303EN/03 9.CONNECTION OF I/O Link SLAVE DEVICES

NOTE
Modules need to be spaced at least 32 mm apart, in which case a flat cable of
about 20 mm in length is required. To install modules further away from each
other, the cable length will be 20 mm plus the extra distance. Note that the
maximum length of a flat cable is 300 mm. To ensure adequate ventilation,
install the modules in such a way that the flat cables lie on top of them. The
basic module has a vent at the top (as indicated by the dotted lines in the above
figure). When connecting modules, install expansion modules so that the flat
cables do not cover the vent, as shown in the above figure.
Therefore, for direct connection to the connection printed circuit board,
expansion modules are installed to the right of the basic module on the
installation plane. For installation using DIN rails or screws, expansion modules
are installed to the left of the basic module on the installation plane.

9.2.19 Other Notes

DO signal reaction to a system alarm
There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link
slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the
machine to operate safely by making a safety circuit outside the I/O module.
The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned
off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.
Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

Xm+15(DO alarm Basic module
detection)

The basic connector panel I/O module is allocated a group of DI addresses (16 bytes) and a group of DO
addresses (8 bytes). Up to three hardware expansion modules can be added or removed as required.
The reason for this address allocation is explained below.

The MPG interface (MPG counter) occupies a DI space from Xm+12 through Xm+14. These addresses
are fixed regardless of whether expansion module 2 or 3 is used, and Xm+12 through Xm+14 must be
allocated as a DI work area to enable the use of the MPG. Therefore, when using an MPG for the i
series CNC, allocate DI addresses in units of 16 bytes. Do not use the DI space from Xm+12 through
Xm+14 for Ladder; the CNC processes the MPG counter value directly.

DI address Xm+15 is used for detecting overcurrent and overheating alarms that occur in the IC used in
the DO driver. [For details, see the section describing the detection of DO (output signal) alarms.]
This address is fixed regardless of whether expansion module 2 or 3 is used, and it must be allocated as a
work area before it can be used. When using this area, therefore, allocate DI addresses in units of 16
bytes.

Basically, I/O addresses can be allocated to the connector panel I/O modules freely. When allocating DI
addresses, however, consider also the addresses that are directly supervised by the CNC, and keep the
following in mind.

Basic module
(DO alarm detection)

DO (output signal) alarm detection

The DO driver of the Basic and Expansion module A/B is capable of detecting an overcurrent and
measuring its own temperature. If an accident, such as the connecting of the cable to ground, causes an
abnormal increase in the load current or in the driver temperature, a protection circuit, which is provided
for each DO driver (1 byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state
until the cause of the problem is eliminated. Even if this occurs, the CNC and I/O module continue
operating. The DI address (Xm+15) identifies the DO driver which has detected the alarm. The table
below shows the correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value
"1" indicates that the corresponding DO driver has detected an alarm. The contents of the Xm+15 area
can be checked by using the DGN screen of the CNC or by performing alarm processing for the area in
advance by using Ladder. This helps alarm detection and recovery.

Allocation of the 2A output module and analog input module

The 2A output module and analog input module can be allocated to any of the spaces for expansion
modules 1, 2, and 3. When an MPG interface is required, the module occupies the space for expansion
module 1; no 2A output module or analog input module can be allocated in the space for expansion
module 1.
The 2A output module does not involve DI points, so that the DI area of the space in which a 2A output
module is allocated is unusable. When a 2A output module is allocated to the space for expansion
module 2, for example, the areas from Xm+6 to Xm+8 cannot be used. (The spaces for the other
modules are not shifted. In this case, the DI space of expansion module 3 remains at Xm+9 through
Xm+11.)

NOTE
1 Xm+1.0 through Xm+1.7 are DI pins for which a common voltage can be
selected. That is, by connecting the COM1 CE54(A02) pin to the +24 V power
supply, a DI signal can be input with its logical state reversed. If, however, a
cable is connected to ground, it has the same effect as inputting an ON state DI
signal. To prevent this from occurring, the connection of the COM1 CE54(A02)
pin to the 0 V power supply is recommended whereever possible.
For safety reasons, the emergency stop signal needs to be allocated to an
appropriate bit of the addresses for which the common voltage is fixed, ranging
from Xm+0.0 to Xm+0.7. See "Address allocation" in Section 8.5.10 for details
of how to allocate the emergency stop signal.
For unused DI pins allocated to the addresses for which the common voltage is
fixed (from Xm+0.0 to Xm+0.7), the logic is fixed to "0". For unused pins
allocated to Xm+1.0 to Xm+1.7 for which the common voltage can be selected,
the logic is fixed to "0" when the COM1 CE54(A02) pin is connected to the 0 V
power supply. When the COM1 CE54(A02) pin is connected to the +24 V
power supply, the logic is fixed to "1". The logic of the unused pins allocated to
Xm+1.0 to Xm+1.7 is variable when the contact of the COM1 CE54(A02) pin is

DO signal reaction to a system alarm
There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link
slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the
machine to operate safely by making a safety circuit outside the I/O module.
The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned
off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.
Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

Xm+15 (DO alarm DO alarm
detection) detection

The operator's panel I/O module is allocated a group of DI addresses (16 bytes) and a group of DO
addresses (8 bytes). This address allocation is explained below.

The MPG interface (MPG counter) occupies DI space from Xm+12 through Xm+14. These addresses
are fixed, and Xm+12 through Xm+14 must be allocated as a DI work area to enable the use of the MPG.
Therefore, when using an MPG for the i series CNC, allocate DI addresses in units of 16 bytes. Do not
use the DI space from Xm+12 through Xm+14 for Ladder; the CNC processes the MPG counter value
directly.

DI address Xm+15 is used for detecting overcurrent and overheating alarms that may occur in the IC used
in the DO driver. [For details, see the section describing the detection of DO (output signal) alarms.]
This address is fixed, and must be allocated as a work area before it can be used. Therefore, when using
this area, allocate DI addresses in units of 16 bytes.

Basically, I/O addresses can be allocated to the operator's panel I/O module freely. When allocating DI
addresses, however, consider also the fixed addresses that are directly supervised by the CNC, and keep
the following in mind.

Turning the DO (output signal) power on and off (DOCOM)

All the DO signals can be turned off simultaneously by turning off (opening) the DO (output signal)
power supply pin "DOCOM". Doing so causes the DO signal status to change as shown below.

DOCOM
OFF
When DO is ON in ON
the sequence OFF

When DO is OFF in ON

NOTE
When the DO signal is in the ON state in the sequence, the ON or OFF state of
the DOCOM pin determines the state of the signal, as indicated by the dotted
lines in the above figure. Do not turn off the +24 V supply, provided by the
CPD1 to the I/O module, during the operation. Turning off the +24 V supply
would cause a CNC communication alarm. When turning on the power, the
+24 V supply to the I/O module must be turned on before or at the same time as
the power supply to the CNC. When turning off the power, the +24 V supply to
the I/O module must be turned off after or at the same time as the power supply
to the CNC.

Parallel DO (output signal) connection

The DO load current can be doubled by connecting two DO points in parallel and turning them on and off
simultaneously in sequence, as shown in the figure below. The maximum load current per DI point is
200 mA. Connecting two DO points in parallel and turning them on at the same time produces a current
of 400 mA. Note that, however, when two DO points are connected in parallel, the leakage current also
doubles while they are off (max. 40 mA).

DO (output signal) alarm detection

The DO driver of the I/O module is capable of detecting an overcurrent and measuring its own
temperature. If an accident, such as connecting the cable to ground, causes an abnormal increase in the
load current or in the driver temperature, a protection circuit, which is provided for each DO driver (1
byte), is activated which keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the
problem is eliminated. Even if this occurs, the CNC and the I/O module continue operating. The DI
address (Xm+15) identifies which DO driver has detected an alarm. The following table shows the
correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value "1" indicates that
the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by
using the DGN screen of the CNC or by performing the alarm processing for the area in advance by using
Ladder. This helps alarm detection and recovery.

NOTE
1 Xm+0.0 through Xm+0.7 and Xm+5.0 through Xm+5.7 are DI pins for which a
common voltage can be selected. That is, by connecting the DICOM0
CE56(A14) or DICOM5 CE57(B14) pin to the +24 V power supply, a DI signal
can be input with its logical state reversed. If, however, a cable is connected to
ground, it has the same effect as inputting an ON state DI signal. To prevent
this from occurring, the connection of the DICOM0 CE56(A14) and DICOM5
CE57(B14) pins to the 0 V power supply is recommended whereever possible.
For safety reasons, the emergency stop signal needs to be allocated to an
appropriate bit of the addresses for which the common voltage is fixed. See
"Address allocation" in Section 9.6.9 for details of how to allocate the emergency
stop signal.
For unused DI pins allocated to the addresses for which the common voltage is
fixed, the logic is fixed to "0". For unused pins allocated to the addresses for
which the common voltage can be selected, the logic is fixed to "0" when the
DICOM0 CE56(A14) or DICOM5 CE57(B14) pin is connected to the 0 V power
supply. When the DICOM0 CE56(A14) or DICOM5 CE57(B14) pin is
connected to the +24 V power supply, the logic is fixed to "1". The logic of the
unused pins is variable when the contacts of the DICOM0 CE56(A14) and
DICOM5 CE57(B14) pins are open.
2 An output DC voltage of +24 V at CE56 (B01) and CE57 (B01) is for DI signals.

DO signal reaction to a system alarm
There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link
slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the
machine to operate safely by making a safety circuit outside the I/O module.
The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned
off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.
Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

Basically, this 48/32-point I/O module is allocated a group of DI addresses (16 bytes) and a group of DO

The MPG interface (MPG counter) occupies DI space from Xm+12 through Xm+14. These addresses
are fixed, and Xm+12 through Xm+14 must be allocated as a DI work area to enable the use of the MPG.
Therefore, when using an MPG for the i series CNC, allocate DI addresses in units of 16 bytes.
Do not use the DI space from Xm+12 through Xm+14 for Ladder; the CNC processes the MPG counter
value directly.

in the above figure. Do not turn off the +24 V supply provided by the CPD1 to
the I/O module during the operation. Turning off the +24 V supply causes a

The DO load current can be doubled by connecting two DO points in parallel and turning them on and off
simultaneously in sequence, as shown in the figure below. The maximum load current per DI point is
200 mA. Connecting two DO points in parallel and turning them on at the same time produces a current
of 400 mA. Note that, however, when two DO points are connected in parallel, the leakage current also

DO (output signal) alarm detection

The DO driver of the I/O module is capable of detecting an overcurrent and measuring its own

the problem is eliminated. Even if this occurs, the CNC and I/O module continue operating. The DI
address (Xm+15) identifies the DO driver which has detected the alarm. The following table shows the
correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value "1" indicates that
the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by

9.5.8 DI/DO Signal Specifications

This subsection describes the specifications of the DI/DO signals used with the basic module and
expansion module.

DI (input signal specifications)

Number of points 48 points (per module)
Contact rating 30 VDC, 16 mA or more
Leakage current between 1 mA or less (26.4 V)
contacts when opened
Leakage current between 2 V or less (including a cable voltage decrease)
contacts when closed
Delay time The receiver delay time is 2 ms (maximum).
In addition, [I/O Link transfer time between CNC and I/O module (2 ms
maximum)] + [ladder scan period (depending on CNC)] must be considered.

DO (output signal specifications)

Number of points 32 points (per module)
Maximum load current when ON 200 mA or less including momentary variations
Saturation voltage when ON 1 V (maximum) when the load current is 200 mA
Withstand voltage 24 V +20% or less including momentary variations
Leakage current when OFF 20 µA or less
Delay time The driver delay time is 50 µs (maximum). In addition, [I/O Link transfer time
between CNC and I/O module (2 ms maximum)] + [ladder scan period
(depending on CNC)] needs to be considered.

ON/OFF of the power supply (DO common) for DO signals (output signals)
By turning off (opening) the power supply pin (DOCOM) for the DO signals (output signals), all the DO
signals of each module can be turned off at the same time. At this time, the DO state is as shown below.
ON
DOCOM
OFF
DO state when DO is ON
on in the sequence
OFF

DO state when DO is ON
off in the sequence OFF

NOTE
When DO is on in the sequence, the ON/OFF state of DOCOM is directly
reflected in the DO state as indicated above by the dashed box.
The +24 V signal to be supplied to the I/O module must not be turned off during
operation. Otherwise, a CNC communication alarm is issued. Ensure that +24 V
is supplied either when or before the power to the CNC is turned on, and that
+24 V is removed either when or after the power to the CNC is turned off.

Parallel DO (output signal) connection

A DO load current two times larger can be obtained by connecting DO points in parallel and exercising
ON/OFF control at the same time in the sequence as shown below. Namely, the maximum load current
per DO point is 200 mA, but 400 mA can be obtained by connecting two DO points in parallel and
turning on the two DO points at the same time. In this case, however, the leakage current is also doubled
up to 40 μA when the DO points are turned off.

DO signal reaction to a system alarm
There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link
slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the
machine to operate safely by making a safety circuit outside the I/O module.
The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned
off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.
Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

Address allocation
For the connector panel I/O module, I/O addresses are mapped as follow:

DI space map DO space map

Xm Yn
Xm + 1 Yn + 1 Basic module
Xm + 2 Basic module Yn + 2
Xm + 3 Yn + 3
Xm + 4 Yn + 4
Xm + 5 Yn + 5 Expansion module
Xm + 6 Yn + 6
Xm + 7 Yn + 7
Xm + 8 Expansion module
Xm + 9
Xm + 10
Xm + 11
Xm + 12 (for 1st MPG)
Xm + 13 (for 2nd MPG) Basic module
Xm + 14 (for 3rd MPG)
Xm + 15 (for DO alarm
detection)

Each of Xm and Yn represents the start address of the module on the I/O Link.
Basically, I/O module type-2 is allocated a group of DI addresses (16 bytes) and a group of DO addresses
(8 bytes). Add or remove expansion module hardware as required. The reason is explained below.

The MPG interface (MPG counter) occupies a DI space from Xm+12 to Xm+14. These addresses are
fixed regardless of whether an expansion module is used, and Xm+12 to Xm+14 must be allocated as a
DI work area to enable the use of an MPG. Therefore, when using an MPG, allocate DI addresses in units
of 16-byte groups. The CNC directly processes the value of the MPG counter. So, ensure that the ladder
does not use this area.

DI address Xm+15 is used to detect an overheating alarm issued for a cause such as overcurrent of the IC
used for a DO driver. Address Xm+15 is fixed regardless of whether an expansion module is used. This
address must be allocated as a work area before this address can be used.

For the reason mentioned above, allocate DI addresses for I/O module type-2 in units of 16-byte groups.

DO (output signal) alarm detection

The DO driver of the basic module and expansion module A/B has a function for detecting a load
overcurrent and its temperature. If an accident such as the connecting of the cable to ground causes an
abnormal increase in the load current or in the DO driver temperature, a protection circuit, which is
provided for each DO driver (1 byte), is activated and keeps the 1-byte DO signal in the OFF state until
the cause of the problem is eliminated. Even in this case, the CNC and I/O module continue operation
with no alarm issued. However, the DI address (Xm+15) identifies the DO driver that has detected the
alarm. The table below indicates the correspondence between the DI address (Xm+15) bits and the DO
addresses. Bit value "1" of the DI address (Xm+15) indicates that the corresponding DO driver has
detected an alarm. If a DO alarm is issued, troubleshooting and recovery can be enhanced by checking the
contents of the Xm+15 area with the DGN screen of the CNC or by performing Xm+15 alarm processing
in advance with the ladder.

Since readout from a manual pulse generator (X12 to X14) is directly performed
by the CNC, only the above assignment must be performed by the PMC.

If the number of DI/DO points is not sufficient, external I/O units such as the dispersed I/O can be added
using the FANUC I/O Link.
A MIL-compatible ribbon cable connector is used as the interface connector of the I/O unit for 0i to
simplify connection to the connector panel.
The connector can also be used for the Series 0i Mate.

DO signal reaction to a system alarm

There is a possibility that the I/O unit will not operate normally due to a failure of CNC or I/O Link slave
module, or abnormally power supply voltage. To prevent accidents even in this case, design the machine
to operate safely by making a safety circuit outside the I/O unit.
The circuit of this I/O unit is designed so that all DO signals are turned off if a system alarm is occurred
in the CNC which controls the I/O unit, or if a power of the CNC or the I/O unit is turned off. However, it
cannot be guaranteed that DO signals of the I/O unit will certainly be turned off. Therefore, manage
signals related to safety by making a safety circuit outside this I/O unit.

DO (output signal) alarm detection

The DO driver of the I/O unit for 0i is capable of detecting an overcurrent and measuring its own
temperature. If an accident, such as the connecting of the cable to ground, causes an abnormal increase in
the load current or in the driver temperature, a protection circuit, which is provided for each DO driver (1
byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the
problem is eliminated. Even if this occurs, the CNC and I/O module continue operating. The DI address
(Xm+15) identifies the DO driver which has detected the alarm. The following table shows the
correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value "1" indicates that
the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by
using the DGN screen of the CNC or by performing alarm processing for the area in advance by using
Ladder. This helps alarm detection and recovery.

9.6.2 Cautions
The following cautions must be observed when using I/O signal receivers and drivers for the machine
interface.

DI Signals and Receivers

DI signals are basically of the sink type (a type that drains energy). Some DI signals, however, can be
set to either sink type or source type (a type that supplies energy). See the description of the I/O board
in the following section for details.
A common signal is provided for selectable receivers. Whether the common signal is connected to 0 V
or 24 V determines whether a DI signal is of sink or source type.
A source type DI signal is undesirable from the viewpoint of safety, however, because if the input signal
line is grounded, it will be latched in the same state as that existing when the contact is closed. It is
recommended that all DI signals be set to sink type.
Always connect the common signal to either 0 or 24 V; do not leave it open.

DO Signals and Drivers

The driver of DO signals is source type (a type that supplies energy, non-insulating).
There is a possibility that the I/O unit will not operate normally due to a failure of CNC or I/O Link slave
module, or abnormally power supply voltage. To prevent accidents even in this case, design the machine
to operate safely by making a safety circuit outside the I/O unit.
The circuit of this I/O unit is designed so that all DO signals are turned off if a system alarm is occurred
in the CNC which controls the I/O unit, or if a power of the CNC or the I/O unit is turned off. However, it
cannot be guaranteed that DO signals of the I/O unit will certainly be turned off. Therefore, manage
signals related to safety by making a safety circuit outside this I/O unit.

NOTE
Output signal driver
Each of the output signal driver devices used on this I/O board outputs eight
signals.
A driver device monitors the current of each output signal. If it detects an
overcurrent on an output, it turns off the output. Once an overcurrent causes
an output to turn off, the overcurrent is no longer present. Then, the output is
turned on again. In ground-fault or overload conditions, outputs may turn on
and off alternately. This phenomenon also occurs when a load with a high
surge current is connected.
Each driver device contains an overheat detector circuit. If an overcurrent is
observed on an output continuously because of a ground-fault or similar reason
and the temperature in the device rises, the overheat detector circuit turns off all
eight outputs. The output-off state is maintained. This state can be released
by logically turning off then on again the outputs after the internal temperature of
the device drops to a specified level. This state can also be released by turning
off the system power supply.
The output signals of the driver devices are assigned the following addresses:
Device #0: Yn+0.0 to Yn+0.7
Device #1: Yn+1.0 to Yn+1.7
Device #2: Yn+2.0 to Yn+2.7
Device #3: Yn+3.0 to Yn+3.7
Device #4: Yn+4.0 to Yn+4.7
Device #5: Yn+5.0 to Yn+5.7
Device #6: Yn+6.0 to Yn+6.7
Device #7: Yn+7.0 to Yn+7.7
If NC diagnosis shows that an output is on but the output is actually not turned
on, an overload on that output or another output in the same device may have
turned off the eight outputs of that device. In such a case, turn off the system
power supply and remove the cause of the overload.

Example: When cable A66L-0001-0286 is used
This cable consists of three pairs of signal lines and six power wires (20/0.18, 0.0394 Ω/m).
When these three cables are used for 0V and 5V lines, the cable length is:

The maximum distance is, however, 50 m for the transmission of a pulse signal from the manual pulse
generator. The cable length is, therefore, up to 50 m.
The maximum cable length is 38.37 m when using the two manual pulse generators, or 25.58 m when
using the three generators.

Manual Handle Allocation Function

Usually, if two or more units equipped with a manual handle interface are connected with an I/O LINK,
the manual handle interface of the first unit connected to the I/O LINK will be automatically enabled.
The use of this function enables the manual handle interfaces of the second and subsequent units. By
setting bit 1 of parameter No. 7105, the manual handles associated with the X addresses set in parameters
Nos. 12305 to 12307 can be allocated as the first, second, and third manual handles, respectively.
Up to three manual handles can be allocated.

Fig. 9.7.1 System which uses FANUC I/O Link connection units

This system enable I/O data transfer between two independent FANUC I/O Link
master devices. When the system is adjusted and maintained, the FANUC I/O Link
can be operated with the system power for one of the FANUC I/O Link lines
switched off, that is, the link operation is stopped.

NOTE
Take the following point into consideration when you design your system.
1. If one of the links is stopped, the system power supply is turned off for
maintenance or adjustment, or the link is stopped due to a failure of CNC or
I/O Link slave module, the circuit of this unit is designed so that all DI signals
sent from a system at rest consists entirely of zeros.
2. If one of the links is stopped, either abnormally or normally, it takes up to
several hundred milliseconds for NOTE 1 function to take effect. During this
period, that data which exists immediately before the link stops is sent out.
Take this into account when designing your system.
3. It cannot be guaranteed that the operation described to NOTE 1 and NOTE2
is carried out that way. Therefore, manage signals related to safety by
making a safety circuit outside this FANUC I/O Link connection unit.

For the 0i-D, the maximum number of β amplifiers with I/O Link that can be connected to a control unit
depends on the maximum number of FANUC I/O Link points provided by that control unit, as well as
their assignments. The maximum number of DI/DO points of the FANUC I/O Link is 1024/1024. On
the other hand, the number of DI/DO points occupied by a β amplifier with I/O Link is 128/128. So, if
only β amplifiers with I/O Link are connected to the FANUC I/O Link, up to eight β amplifiers with I/O
Link can be connected. For the 0i Mate, number of connectable amplifiers depends on the model.

9.8.4 Address Assignment by Ladder

If the β amplifier with I/O Link is used as an I/O Link slave, I/O addresses are assigned in the PMC in the
CNC. Because data output from the slave is made in 16-byte units, the number of input/output points
must be set to 128.
The module names are OC02I (input) and OC02O (output).
The BASE is always 0, and the SLOT is 1.

NOTE
1 Xm+3.0 to 3.7 have a common line that is possible to select the source/sink
type. If DICOM (CM69-B06pin) is connected to +24V, the DI signal logic is
negative. But in this connection, if the DI signal wires happen to drop the ground
level, the status of the DI signal is same as the DI signal is "ON". From the
safety viewpoint, DICOM should be connected 0V.
2 From the safety viewpoint, Emergency Stop signal must be assigned on the
address Xm+0.0 to 0.7 or Xm+1.0 to 1.7 or Xm+2.0 to 2.7. As refer to the 5.
DI/DO mapping, assign the Emergency stop DI.
3 Xm+0.0 to 0.7, Xm+1.0 to 1.7 and Xm+2.0 to 0.7 common lines are fixed. So, if
these DI pins in this address open, the status of these one stay "0". And in case
of Xm+3.0 to 3.7 which have a selectable common line, if the DICOM
(CM69-B06pin) is connected to 0V and these DI pins open, the status of these
one stay "0". And if the DICOM are connected to +24V and these DI pins open,
the status of these one stay "1". And if the DICOM is not connected to 0V or

9.9.3.7 General-purpose DO signal connection

DO signal reaction to a system alarm

There is a possibility that the Operator’s panel will not operate normally due to a failure of CNC or I/O
Link slave module, or abnormally power supply voltage. To prevent accidents even in this case, design
the machine to operate safely by making a safety circuit outside the Operator’s panel.
The circuit of this Operator’s panel is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the Operator’s panel, or if a power of the CNC or the Operator’s
panel is turned off. However, it cannot be guaranteed that DO signals of the Operator’s panel will
certainly be turned off. Therefore, manage signals related to safety by making a safety circuit outside this
Operator’s panel.

Example of the 3 manual pulse generator connection is as follows. If this CNC uses some I/O unit having
MPG interface (ex. Dispersion type I/O module for panel) and this operator's panel, the MPG interface
nearest the CNC is only available on the I/O Link connection.

9.9.5 I/O Mapping

I/O address map is as follows.

DI mapping should be assigned 1 group = 16 byte mapping and DO mapping should be assigned 1 group
= 8 byte mapping. The reason is as follows.
MPG interface(the counter for MPG) uses Xm+12 to Xm+14 area and it is fixed. And if MPG interface
will be used, Xm+12 to Xm+14 area must be assigned. therefore, in case of 30i series and using MPG
interface, DI mapping must be assigned 16 byte mapping. MPG counter area are directly processed by
CNC software. So you must not use this area by customer ladder.
When the MPG interface is not used, its DI area may be assigned to another I/O group. I/O mapping of
the standard machine operator's panel can basically be assigned to any area of addresses. As for DI
mapping, however, there are fixed signals directly monitored by the CNC. The fixed signals cannot be
assigned to the keyswitch-input area. To use the fixed signals, therefore, assign them to an area other
than the keyswitch-input area.

NOTE
The +24V power supplied to this connector must be turned OFF during
operation. Turning it OFF will cause a CNC communication alarm to be
generated. Make sure that at power ON, the supply of this +24V power is at the
same time as or earlier than the supply of the power to the CNC and that at
power OFF, it is at the same time as or later than the interruption of the power to
the CNC.
When the CNC connected to this operator's panel with an I/O Link is to be turned
off, the power to this operator's panel must also be turned off.

9.10.3.2 Emergency stop switch

The emergency stop switch has contact A in two circuits and contact B in two circuits. (This signal is
not sent to the CNC with a FANUC I/O Link.)
The machine tool builder is required to connect the switch to other DI/DO devices.

Recommended wire material: A66L-0001-0286 (#20 AWG y 6 + #24 AWG y 3 pair)

Recommended connectors: A02B-0120-K303 (including the following connector and case)
(Connector: Hirose Electric FI40B-2015S Soldering type)
(Case: Hirose Electric FI-20-CV)
Recommended cable: A02B-0120-K841 (7 m) (cable for three manual pulse generators)
A02B-0120-K848 (7 m) (cable for two manual pulse generators)
A02B-0120-K847 (7 m) (cable for one manual pulse generator)
(These cables are not used for the connection in the portion indicated by "Wiring".)

Calculate the maximum allowable length of the cable for the manual pulse generator, with the method
described below.
Manual pulse generators are supplied with 5 VDC power. The drop in voltage due to cable resistance
must not exceed 0.2V (on 0V and 5V lines in total).

Where
m 0.1 : Power supply current for the manual pulse generator = 0.1 A

R R : Wire resistance per unit length [Ω/m]
m : Number of 0-V wires (= number of 5-V wires)
L : Cable length [m]

Therefore,

Example: When cable A66L-0001-0286 is used
This cable consists of three pairs of signal lines and six power wires (20/0.18, 0.0394 Ω/m).
When these three cables are used for 0V and 5V lines, the cable length is:

- 262 -
B-64303EN/03 9.CONNECTION OF I/O Link SLAVE DEVICES

Thus, the length is 76.75 m. (Because of the applicable regulation of FANUC, however, the length is
limited to 50 m.)
For two units, the cable can be extended to 38.37 m.
For three units, it can be extended to 25.58 m.

If the cable A66L-0001-0284#10P is used,

the cable can be extended to 12.88 m for one unit,
6.44 m for two units, and
4.29 m for three units.

DO signal reaction to a system alarm

There is a possibility that the Operator’s panel will not operate normally due to a failure of CNC or I/O
Link slave module, or abnormally power supply voltage. To prevent accidents even in this case, design
the machine to operate safely by making a safety circuit outside the Operator’s panel.
The circuit of this Operator’s panel is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the Operator’s panel, or if a power of the CNC or the Operator’s
panel is turned off. However, it cannot be guaranteed that DO signals of the Operator’s panel will
certainly be turned off. Therefore, manage signals related to safety by making a safety circuit outside this
Operator’s panel.

(This address is not used with
expansion module C.)

Basically, the module is allocated a group of DI addresses (16 bytes) and a group of DO addresses (8
bytes). Add or remove up to three expansion modules by hardware as required. The reason is explained
below.
The MPG interface (MPG counter) occupies a DI space from Xm+12 to Xm+14. These addresses are
fixed regardless of whether expansion module 2 or 3 is used, and Xm+12 to Xm+14 must be allocated as
a DI work area to enable the use of the MPG. Therefore, when using an MPG with the i series, allocate DI
addresses in units of 16-byte groups. The CNC directly processes the value of the MPG counter. So,
ensure that the ladder does not use this area.
DI address Xm+15 is used to detect an overheating alarm issued for a cause such as overcurrent of the IC
used for a DO driver. (For details, see Subsection 9.11.6.2, "DO alarm detection".) Address Xm+15 is
fixed regardless of whether expansion module 2 or 3 is used. This address must be allocated as a work
area before this address can be used. When using this area, therefore, allocate DI addresses in units of
16-byte groups.

Addresses of expansion module C

Expansion module C is a module with 16 points for output only but can be allocated in any space of
expansion module 1, 2, or 3. With this module, DO alarm information (2 bytes/module, with DO alarm
information provided for each DO point), which is described later, is allocated to the DI area. For the
relationship between DO bits and DO alarm information, see "Expansion module C" in Subsection
9.11.6.2.

Addresses of expansion module D

<Digital output>
Expansion module D has four analog input channels and has only one 12-bit digital output channel in the
3-byte DI area. The DI format is as indicated below. The digital output addresses start at the first
even-numbered address in the 3-byte area. (See the next page.)
Address in expansion module D 7 6 5 4 3 2 1 0
Xm (even address) D07 D06 D05 D04 D03 D02 D01 D00
Xm+1 (odd address) 0 0 CHB CHA D11 D10 D09 D08

- 308 -
B-64303EN/03 9.CONNECTION OF I/O Link SLAVE DEVICES
D00 to D11 represent 12-bit digital output data (represented as a complement). D00 corresponds to the
weight of 20, and D11 corresponds to the weight of -211. This means that D11 corresponds to the sign bit
of a two's complement.
CHA and CHB select a converted data channel. This means that when the two bytes above are read by a
ladder program, A-D converted data on an input channel selected by CHA and CHB is read as D11 to
D00.

<Channel selection>
When expansion module D is used, which of the four channels is to be output to the DI area of the
module needs to be selected by a ladder program. The channel switching DO points, CHA and CHB, are
mapped to the DO area of the module as indicated below. The symbol × represents an unused bit, and an
unused bit may be set to either 1 or 0.

Be sure to allocate the start address in the DI area of the basic module including expansion module D at

9.11.6.2 DO alarm detection

Basic module, expansion modules A and B
The DO driver has a function for detecting a load overcurrent and its temperature. If an accident such as
the connecting of the cable to ground causes an abnormal increase in the load current or in the DO driver
temperature, a protection circuit, which is provided for each DO driver (1 byte), is activated and keeps the
1-byte DO signal in the OFF state until the cause of the problem is eliminated. Even in this case, the CNC
and I/O module continue operation with no alarm issued. However, the DI address (Xm+15) identifies the
DO driver that has detected the alarm. The table below indicates the correspondence between the DI
address (Xm+15) bits and the DO addresses.
Bit value "1" of the DI address (Xm+15) indicates that the corresponding DO driver has detected an alarm.
If a DO alarm is issued, troubleshooting and recovery can be enhanced by checking the contents of the
Xm+15 area with the DGN screen of the CNC or by performing Xm+15 alarm processing in advance
with the ladder.

NOTE

Expansion module D does not have this function.

Expansion module C
The DO driver of expansion module C has not only the overheat protection function (overcurrent
detection and temperature detection) as available with the basic module and expansion modules A and B
but also an over voltage protection function and disconnection detection function, and a DO bit is
allocated to each protection circuit.
When any of these functions is activated, the bit corresponding to the LED "ALARM" of the module is
turned on. The CNC continues operation with no alarm issued. However, the DI address area identifies
which DO driver has detected an alarm. The next page indicates the correspondence between the DI
address bits and the DO address bits.

How to view the table above
DO alarm data assigned to bit 5 of address Yn+3 is written to bit 5 of Xm+4.
NOTE
1 DO alarm information on expansion module C is written not to Xm+15 but to the
address indicated above.
2 Xm+5, Xm+8, and Xm+11 cannot be used with expansion module C.
3 Even when expansion module A or B is allocated as expansion module 1 or 2,
address space is not shifted.

The DO driver with the DI address bit set to 1 has detected an alarm. If a DO alarm is issued,
troubleshooting and recovery can be enhanced by checking the contents of the DI area with the DGN
screen of the CNC or by performing DI alarm processing in advance with the ladder.
If a protection function is activated, turn off the DO power and system power then correct the cause that
has activated the protection function.

The table below indicates the DO output state and alarm bit state set when each protection function is
activated.

9.CONNECTION OF I/O Link SLAVE DEVICES B-64303EN/03

NOTE
1 If the overheat protection function or over voltage protection function among the
protection functions above is activated, the DO bit is kept OFF until the cause is
eliminated. When the cause is eliminated, the DO bit is set to ON without
restarting the system.
2 Disconnection detection is performed by monitoring, with an output element in
the module, the current flowing through a load when DO output is ON. When the
detected current value is about 100 mA or less, disconnection detection is
assumed. So, when a device (such as an LED) with a small load current is
connected, the DO alarm state results, assuming disconnection detection. Unlike
the other protection functions, however, this function does not turn off DO output.
If a connection is reactivated after the state of disconnection is once set,
disconnection detection is canceled without restarting the system.

9.11.7.2 DO signal reaction to a system alarm

There is a possibility that the I/O module will not operate normally due to a failure of CNC or I/O Link
slave module, or abnormally power supply voltage. To prevent accidents even in this case, design the
machine to operate safely by making a safety circuit outside the I/O module.
The circuit of this I/O module is designed so that all DO signals are turned off if a system alarm is
occurred in the CNC which controls the I/O module, or if a power of the CNC or the I/O module is turned
off. However, it cannot be guaranteed that DO signals of the I/O module will certainly be turned off.
Therefore, manage signals related to safety by making a safety circuit outside this I/O module.

9.11.7.3 Parallel DO (output signal) connection

Basic module, expansion modules A and B
With the basic module and expansion modules A and B, a DO load current two times larger can be
obtained by connecting DO points in parallel and exercising ON/OFF control at the same time in the
sequence as shown below. Namely, the maximum load current per DO point is 200 mA, but 400 mA can
be obtained by connecting two DO points in parallel and turning on the two DO points at the same time.
In this case, however, the leakage current is also doubled up to 40 μA when the DO points are turned off.
Note that the bits that can be set to ON/OFF at the same time must belong to the same address. (For
example, bits at address Yn+3 may be set to ON/OFF at the same time.)

－: Blue

1) Peel off the coating of the AS-i cable then screw the cable onto the terminal block of the AS-i
converter.
2) This terminal block is detachable, and work can be done on the terminal block after being detached
from the AS-i converter. When attaching the terminal block, firmly tighten the screws for mounting
the terminal block.
3) To facilitate AS-i cable branching, two AS-i + terminals and two AS-i − terminals are provided. A +
terminal and a − terminal are connected with each other in the AS-i converter. Use those terminals
that can be handled more easily.
4) Do not connect two cables to each terminal.
5) Connect the GND terminal to ground.

NOTE
To protect against induction noise, separate high-voltage lines and the power
line from the AS-i communication cable as much as possible. (It is
recommended to separate high-voltage lines and the power line from the AS-i
communication cable by 300 mm or more.) Moreover, attach a surge absorber to
a device that tends to generate noise.

When the 7-segment LEDs indicate E1, the registered configuration may have

below.
Turn off the power.

Turn on the power again while setting the switch to SET.

The 7-segment LEDs indicate "E1". (Keep the switch set to SET.)

Keep the switch set to SET until the LED ”CM” switches from off to on or vice versa.
(This operation may require 5 seconds or more.)

Release the switch. Next, turn off the power then turn on the power again to restart the system.

The register configuration is recovered if the 7-segment LEDs do not indicate "E1". (If the LED ”CM” is
turned on, protect the registered configuration in preparation for subsequent operation. Keep the switch
set to SET until the LED "CM" is turned off. This operation may require 5 seconds or more.)

If the 7-segment LEDs still indicate "E1" after the operation above,
replace the AS-i converter.

* Note that if "E1" is indicated, the CNC may not be started.

AS-i converters with this function were shipped in June, 2005 or later.
The corrective action mentioned above cannot be applied to those AS-i
converters that were shipped earlier. In this case, replace the AS-i converter if an
EEPROM error occurs.

9.CONNECTION OF I/O Link SLAVE DEVICES B-64303EN/03

9.12.8.2 Normal operation

(1) Operation mode
The protection mode is used in normal operation.
In this mode, a configuration mismatch error occurs and CER is turned on if communication with an AS-i
slave unit is disabled for a cause such as a disconnected cable, AS-i communication error, and slave unit
failure.

(2) Alarm monitor

Monitor the alarm signal (alarm issued by bit 1 of X+18 set to 1) on the I/O Link with a CNC ladder
program and ensure that a PMC alarm is issued to notify maintenance staff if an error occurs.
Check the cause of an alarm with the LED indications and the status signals (X+16 to X+18) on the I/O
Link then take a proper corrective action.

(3) Configuration mismatch

A configuration mismatch means that the current slave configuration differs from the slave configuration
registered when the operation mode is switched from the configuration mode to the protection mode.
Pressing the DISP switch in the protection mode when CER is turned on displays all
configuration-mismatching slave numbers sequentially.
Monitor for this configuration-mismatching error (bit 7 of X+16) with a CNC ladder program and ensure
that a PMC alarm is issued to notify maintenance staff if this error occurs. To take a proper corrective
action, maintenance staff can identify the slave number in question by pressing the DISP switch as
mentioned earlier.
With a ladder program, configuration-mismatching slave numbers can be displayed on the display unit of
the CNC.

(4) Causes of configuration mismatch and corrective action

A configuration mismatch can occur for a cause such as a disconnected cable, communication error, and
AS-i slave unit failure.

a) Disconnected cable
The cause may be identified as a disconnected cable if all slaves after a particular slave are
configuration-mismatching slaves.

b) Communication error
A temporary communication error may be recovered by restarting the operation. In this case, however,
check whether a large noise source is located nearby and whether all connections are made normally.

c) Slave unit failure

If normal operation cannot be resumed after a restart, the cause may be a slave unit hardware failure.
When only one slave unit is to be replaced, an address number can be automatically set with the
automatic addressing function.
When multiple slave units are to be replaced, addresses for the slave units can be set on a one-by-one
basis with the automatic addressing function or addresses for all slaves can be set beforehand using the
addressing device.

d) No address setting
An AS-i slave with address "0" is connected.

(5) AS-i data ready flag (X+18: Bit 0)

Before reading DI signals with a ladder, check that the AS-i data ready flag is set to 1. If the flag is set to
0, do not use DI signals.

10.STOP AND EMERGENCY STOP B-64303EN/03

10 STOP AND EMERGENCY STOP

10.1 STOP MODES
There are the following stop modes:
1. Stop by shutting off the motor power
2. Controlled stop without shutting off the motor power
3. Stop by shutting off the motor power after a controlled stop

A controlled stop is the quickest. However, a stop may be made by immediately shutting off the motor
power for safety reasons.

WARNING
Pressing the RESET key stops the running program. As a result, the servo axis
stops and the spindle axis remains rotating without changing the speed. The
RESET key may not function due to an MDI failure or the like, so, for safety, use
the emergency stop button instead of the RESET key to stop the motor safely.
When a failure of the CNC, machine contact, or connection is also assumed,
further safety actions must be taken.

10.2 SHUTTING OFF THE MOTOR POWER

The motor power may be shut off through an IGBT (transistor) or an electromechanical scheme that
controls mechanical contacts. When an αi series amplifier is used, the motor power is shut off by an
IGBT (transistor) based on the CNC alarm state (or Ladder program). To shut off the motor power
through an electromechanical scheme, a line contactor must be installed on the power input line in the
power supply module, thereby providing a direct contactor shut-off route. (See Fig. 10.5 in Section 10.5,
"EMERGENCY STOP SIGNAL.")
The power supply module provides MCC control signals (MCCOFF3 and MCCOFF4) for controlling the
contactor. However, these signals are enabled only when the motor power to all servo and spindle
amplifiers connected to the power supply module is shut off through the IGBT.
Example 1)
When the *ESP signal is input to the power supply module
The motor power to both servo and spindle amplifiers is shut off by the IGBT, after which MCC
control signals are output.
Example 2)
When a servo alarm occurs
The motor power to the servo amplifier is shut off by the IGBT. When the spindle works without
any trouble, however, the spindle can be controlled independently and the motor power to the
spindle amplifier is not shut off by the IGBT. In this case, MCC control signals are not output.
When a spindle emergency stop signal is input using the Ladder program, the spindle motor is
decelerated to a stop. Then, the motor power is shut off through the IGBT, MCC control signals
are output, and the motor power is shut off electromechanically.
A failure in the amplifier may disable MCC control signals. To ensure motor power shut-off, therefore,
a circuit must be designed in a redundancy configuration having a route that is independent of the shut-off
function of the amplifier.

- 346 -
B-64303EN/03 10.STOP AND EMERGENCY STOP

10.3 STOPPING THE SPINDLE MOTOR

While the spindle motor is running, shutting off the motor power allows the spindle motor to coast at a
speed maintained before shut-off and eventually stop (after a while). However, there may be cases
where the spindle motor should be stopped as soon as possible for safety reasons. In such cases, a stop
of the spindle motor depends on a Ladder program prepared by the machine tool builder. If the CNC
detects an abnormal condition, it outputs an alarm to the PMC. The Ladder program should specify
processing to be performed when an alarm is output: allowing the spindle to continue running,
decelerating the spindle to a stop, or causing the spindle to coast, for example.
To decelerate the spindle to a stop, a spindle emergency stop signal (such as *ESPA (G71.1) or *ESPB
(G75.1)) can be input in the PMC. Inputting this signal cause the spindle to be decelerated to a stop.
(A Ladder program must be created so that this signal is input if an alarm occurs.) The same effect can
be achieved by using the PSM emergency stop input (connector CX4). When an emergency stop signal
is connected to the *EMGPSM emergency stop input (connector CX4), therefore, the spindle is
decelerated to a stop if the CNC enters the emergency stop state.

CAUTION
1 If the CNC enters the system alarm state, the Ladder program does not run. In
this case, the spindle amplifier can be decelerated to a stop. Make proper
parameter settings because such a stop depends on the settings.
2 If the spindle motor cannot be controlled due to an alarm in the spindle amplifier
itself or for some other reason, the motor power is shut off by the IGBT
immediately. After the servo motor has stopped, an MCC control signal is
output.

10.4 STOPPING THE SERVO MOTOR

Shutting off the motor power brings the servo motor to a dynamic brake stop. A dynamic brake stop is
braking performed by separating the synchronous rotator from the driving power, and consuming
generated electric energies with the coil as well as the built-in resistor of the servo amplifier. With this
function, shutting off the motor power does not allow the servo motor to coast like the
spindle motor.
Servo motor stop mode depends on the type of a CNC alarm.
Example)
1. PS alarm caused by an NC program error or the like
The motor power is not shut off.
2. CNC fan stop
A single-block stop is made. The motor power is not shut off.
3. Emergency stop state
A dynamic stop is made as a rule. By setting relevant parameters, however, it is also possible to
decelerate the servo motor to a stop, and then to shut off the servo motor power.

10.STOP AND EMERGENCY STOP B-64303EN/03

10.5 EMERGENCY STOP SIGNAL

CAUTION
Using the emergency stop signal effectively enables the design of safe machine
tools. See "Cautions for configuring an emergency stop circuit in compliance
with safety standards."
The emergency stop signal is provided to bring a machine tool to an emergency
stop. It is input to the CNC controller and αi series power supply module. The
power supply module outputs a motor power MCC control signal, which can be
used to switch the power applied to the power supply module on and off. An
emergency stop signal is usually generated by closing the B contact of a
pushbutton switch.
When the emergency stop signal (*ESP) contact is closed, the CNC controller
enters the emergency stop released state, such that the servo and spindle
motors can be controlled and operated.
When the emergency stop signal (*ESP) contact opens, the CNC controller is
reset and enters the emergency stop state, and the servo and spindle motors
stop.
Inputting an emergency stop signal causes the servo motor power to be shut off
through the IGBT, bringing the servo motor to a dynamic brake stop. Even in
this case, however, a servo motor attached to a vertical axis can move under the
force of gravity. To overcome this problem, use a servo motor with a brake.
By using relevant parameters, it is also possible to decelerate the servo motor to
a stop, and then to shut off the servo motor power.
While the spindle motor is running, shutting off the motor power to the spindle
amplifier allows the spindle motor to continue running under its own inertia,
which may be quite dangerous. With an αi series amplifier, when the
emergency stop signal (*ESP) contact opens, it is possible to confirm that the
spindle motor is decelerated to a stop, and then to shut off the spindle motor
power through the IGBT.
When the motor power to both servo and spindle amplifiers is shut off through
the IGBT, the power supply module outputs a motor power MCC control signal,
which can be used to directly shut off the power with an external line contactor.
The CNC controller is designed to detect overtravel by using a software limit
function. Normally, no hardware limit switch is required to detect overtravel. If
the machine goes beyond a software limit because of a servo feedback failure,
however, it is necessary to provide a stroke end limit switch, which should be
connected so that the emergency stop signal can be used to stop the machine.
Fig. 10.5 shows an example showing how to make connections for the
emergency stop signal with this CNC controller and αi series servo amplifier.

WARNING
To use a spindle motor and amplifier produced by a manufacturer other than
FANUC, refer to the corresponding documentation as well as this manual.
Design the emergency stop sequence such that, if the emergency stop signal
contact opens while the spindle motor is rotating, the spindle motor is
decelerated until it stops.

Cautions for configuring an emergency stop circuit in compliance with safety standards

To configure an emergency stop circuit in compliance with JIS safety standards(*), observe the following
cautions. Compliance with these JIS safety standards is a prerequisite for complying with the EC Machine
Instructions.
The method for shutting off the motor power section in the amplifier is based on an IGBT (transistor)
rather than an electromechanical scheme.

- 349 -
10.STOP AND EMERGENCY STOP B-64303EN/03

When configuring an emergency stop circuit, therefore, install a line contactor on the power input line for
motor power in the power supply module in order to ensure electromechanical shut-off, and apply voltage
to the control coil of the contactor via the contactor control output of the power supply module.
A failure in the amplifier may disable the output relay of the power supply module from going off, thus
preventing the line contactor from shutting off the power, even when the emergency stop command input
(*ESP) of the amplifier becomes low.
To secure motor power shut-off, design the emergency stop circuit in a redundancy configuration. To be
specific, the emergency stop circuit must have a direct line contactor shut-off route based on an
emergency stop switch that is independent of the shut-off function of the amplifier.
If a spindle amplifier module is used, shutting off the motor power line during spindle rotation disables
the spindle from stopping quickly because the power regenerative function does not work, allowing the
spindle to coast. So, provide the redundancy circuit mentioned above with a delay function based on an
off-delay timer that allows a usual stop time.
Refer to the following material for detailed descriptions about cautions related to safety circuits.

CABLES
B.1 BOARD-MOUNTED CONNECTORS

B.1.1 Vertical-type Connectors

Models: PCR-EV20MDT (Honda Tsushin)
52618-2011 (Molex Japan)

These board-mounted connectors have been specially developed to achieve the high packing density
required for FANUC products. As explained in the following subsection, Honda PCR series connectors
can be used as cable connectors because the mating mechanism of the newly developed connectors is
compatible with that of the Honda PCR series connectors. To support this specification extensively,
many connector manufacturers are now developing custom-tailored cable connectors. (Note that these
cables cannot be used with screw-fixing cable connector housings.)

B.1.2 Straight and Right-angled Connectors (for Spring and

Screw-fixing Connector Housings)
Models: FI80-20P (HIROSE) (straight connector)
DF1R020WB1 (JAE) (straight connector)
PCR-E20LMDETZ-SL (Honda Tsushin) (right-angled connector)

These connectors are used for the main and option boards. As cable connectors, they are compatible
with screw-fixing connector housings as well as the spring locking connector housings.

B.2 CABLE CONNECTORS

Models: Hirose Electric: FI80-20P (straight connector)
Japan Aviation Electronics Industry: DF1R020WB1 (straight connector)
Honda Tsushin: PCR-E20LMDETZ-SL (right-angled connector)

Cable connectors consist of a connector main body and housing. The models listed below are available.
Those connectors not marked with an asterisk are currently being mass-produced as manufacturer's
standard models. Those marked with an asterisk are produced according to custom specifications by
FANUC.

B.2.1 Strand Wire Press-mount Connector

With this connector, #28AWG wires are press-connected to each pin at the same time. The cost of
producing a cable/connector assembly with this connector model is much lower than with connectors
designed for crimping or soldering.
Connector model
Supplementary description
(manufacturer)
FI-20-CV7 (Hirose) Small and low-profile case. This connector is fixed to the board-mounted
connector with screws. This connector can be connected to the board-mounted
connector on the main board of the LCD-mounted type, but cannot be connected
to the board-mounted connector on the main board of the stand-alone type.

B.2.2 Soldering Type Connector

Details of soldering type connectors and their housings are summarized below.

Table B.2 Details of soldering type connectors and housings

Connector model
Supplementary description
(manufacturer)
PCR-E20FS (Honda) Soldering type connector for general signals. This is suitable for producing
cable assemblies in small quantities, as well as on-site.
FI40-20S (Hirose) Equivalent to Honda PCR-E20FS
FI40B-20S (Hirose) Has the same number of pins as the FI40-20S, but features a wider soldering
(formerly, FI40A-20S) pitch, facilitating soldering and enabling the use of thicker wires. Its reinforced
pins allow wires as thick as #17AWG to be soldered to the FI40B-20S (wires no
thicker than #20AWG can be used with the FI40A-20S). Note, however, that a
thick wire, such as #17AWG, should be used with a more robust housing like the
FI-20-CV6.
FI40B-2015S (Hirose) Features a wider soldering pitch, attained by using the space provided by thinning

(manufacturer)
(formerly, FI40-2015S) out some pins. Also features tougher pins, compared with its predecessor, the
FI40-2015S. These pins can be soldered to wires as thick as #17AWG,
provided that the cable diameter does not exceed 8.5 mm.

Housing model (manufacturer) Supplementary description

FI-20-CV5 (Hirose) Should be used with the FI40B-20S. This is a plastic housing designed for use
with a cable that is 9.2 mm in diameter.
FI-20-CV6 (Hirose) Should be used with the FI40B-20S. This housing, however, can be used with a
thicker cable (such as 10.25 mm) than is possible with the FI-20-CV5. Its
components are die cast.

In addition to the combinations shown in Fig. B.2, Hirose soldering-type connectors can be combined
with the housings listed below. Ensure that the diameter of the cable used with each housing satisfies
the requirements of that housing.

(2) Cable selection

• Always use an external cable (A66L-6001-0026#~) when the cable is to be laid outside the power
magnetics cabinet or main unit cabinet, where it may be pulled, rubbed, or stepped on.

- 426 -
B-64303EN/03 APPENDIX D.OPTICAL FIBER CABLE

• Use an external cable when part of the cabling is to be subject to movement. For example, when
connecting a movable portable operation pendant box to the power magnetics cabinet, the use of an
external cable is desirable because the cable is likely to be bent, pulled, or twisted repeatedly even
though frequent system operation is not expected. However, the force likely to be applied when the
cable is installed or moved for maintenance purposes does not need to be taken into consideration.
• Use an external cable in locations where sparks or flame are a danger. Although the internal cord
type cable (A66L-6001-0023#~) is covered by nonflammable resin, the cover, if exposed to frame
for a long time, may melt, allowing the fiber cable inside to burn.
• Use an external cable when the cable is expected to be pulled with considerable force during
installation (the force applied to the cable must be within the specified tensile strength limit at all
times). For example, even though installing a cable in a cable duct can be regarded as internal
cabling, a cable of the appropriate type must be selected according to the tensile force to be applied
to the cable during installation.
• Both the internal cord type and external cables have the same oil and heat resistance properties.

(3) Procuring the cable

All the optical fiber cables mentioned above are special cable products with optical connectors, which are
designed, produced, and tested to ensure the required system performance and reliability. It is
technically impossible for users to produce these cables or process (cut and reconnect) them after
purchase. Users are requested to purchase cables of the necessary length from an appropriate supplier.
Cables are available from either FANUC or any of the FANUC-approved manufacturers listed in Table
D(d).
(Purchase A66L-6001-0029#~ and A66L-6001-0049#~ from FANUC, however.)

(4) Handling precautions

<1> Protection during storage
When the electrical/optical conversion module mounted on the printed circuit board and the optical
fiber cable are not in use, their mating surfaces must be protected with the lid and caps with which
they are supplied. If left uncovered, the mating surfaces are likely to become dirty, possibly
resulting in a poor cable connection.

<2> Optical fiber cable

• Make sure that the bending radius and tensile strength of the cable are always within their
ranges described in the specifications (see the first item), regardless of whether the cable is
stored or routed and whether operation is in progress or not.
• Although the reinforcing cover of the external cable has sufficient mechanical strength, be
careful not to drop heavy objects on the cable.
• Grasp the optical connector firmly when connecting or disconnecting the cable. Do not pull
on the optical fiber cord itself. (The maximum tensile strength between the fiber cord and
connector is 2 kg. Applying greater force to the cord is likely to cause the connector to come
off, making the cable unusable.)
• Once connected, the optical connector is automatically locked by the lock levers on its top.
To remove the connector, release the lock levers and pull the connector.
• Although optical connectors cannot be connected in other than the correct orientation, always
take note of the connector's orientation before making the connection.
• Before installing an external cable, fix either a wire with a hook or a tension member to the
reinforcing cover of the optical connector and pull the wire or tension member, as shown in Fig.
D(d). This is done to prevent a tensile force from being applied between the fiber cord and
connector. If no tensile force is applied between the fiber cord and connector when installing
the cable, you can hold the reinforcing cover of the connector directly and pull it. In the case
of an internal cord, which does not have a reinforcing cover, apply the same protective
measures, as instructed in Fig. D(d), for that portion of the cable where the two cords are bound
together, in order to prevent a tensile force from being applied between the fiber cord and
connector. In the same way as for an external cable, if no tensile force is applied between the
fiber cord and connector during installation, you can hold the shielded part of the cable directly
and pull it. Because the combined tensile strength of the two cords is only 14 kg, however,
avoid applying too great a force to the cable during installation, regardless of whether you have
taken the protective measures.

• Take care to keep both parts of the optical connector (cable side and PCB side) clean. If they
become dirty, wipe them with tissue paper or absorbent cotton to remove dirt. The tissue
paper or absorbent cotton may be moistened with ethyl alcohol. Do not use any organic
solvent other than ethyl alcohol.
• Fix the reinforcing cover of the external cable or the cord binding portion of the internal cord
type cable by using a cable clamp, as shown in Fig. D(e), to prevent the weight of the optical
fiber cable from being applied directly to the connecting part of the optical connector.

Fig. D(e) Fixing the cable with a clamp

• Any superfluous portion of the cable may be wound into a loops. Should this prove necessary,
make sure the diameter of each loop is at least 150 mm (for an external cable) or at least 100
mm (for an internal cord type cable). Winding the cable into smaller loops may produce sharp
curves that exceed the specified bending radius limit without the user being aware. Such
bending can result in a greater transmission loss, ultimately leading to a communication failure.
• When using a nylon band (cable tie) as a cable clamp, follow the instructions given below.
Also, take care not to apply a bending force to one particular part of the cable when fixing it
with a clamp. Failing to clamp the cable correctly may cut or damage it.

- 429 -
D.OPTICAL FIBER CABLE APPENDIX B-64303EN/03

(External cable)
Do not clamp the uncovered portion of the cable with a nylon band. When clamping the
cable by the reinforcing cover, the clamping force is not an important factor to consider.
However, ensure that the clamping force is as small as possible to ensure that the
reinforcing cover is not deformed by the clamping. If possible, the clamping force
should be 5 kg or less.
(Internal cord type cable)
Lightly clamp the optical cable with a nylon band so that the cable shield is not deformed.
If possible, the clamping force should be 1 or 2 kg (make sure that no force is applied to
the cable). Due care is required when clamping the internal cord type cable because its
cable shield is weaker than the reinforcing cover of the external cable.

(7) Precautions for connection with low-loss optical junction adapter

• Features and attention in use of low-loss optical junction adapter (A63L-0020-0004)
When optical connectors for a conventional optical junction adapter (A63L-0020-0002) are jointed,
the facing ferrules (Note 1) are located about 60 um from each other. This is because the optical
fiber of conventional PCF (plastic clad silica fiber) cables (A66L-6001-0026) may protrude from the
tip of the ferrules (by up to about several um), resulting in the fiber protrusion being damaged when
the ferrules are butted against each other.

- 431 -
D.OPTICAL FIBER CABLE APPENDIX B-64303EN/03

In the low-loss optical junction adapter, the ferrules are butted against each other, thus greatly
reducing the reduction in repeater loss. Therefore, the two optical cables used with the low-loss
optical junction adapters must be dedicated to the adapters.
If a conventional PCF (plastic clad silica fiber) cable (A66L-6001-0026) is used as even one of the
two optical fiber cables for joining the low-loss optical junction adapter, both cables may be
damaged, resulting in deteriorated characteristics.

NOTE

the ferrule.

• Features of low-loss optical cable (A66L-6001-0029#~)

A low-loss optical cable is selected from conventional PCF optical cables (A66L-6601-0026). The
selected cable offers low loss, and its connector section is given special treatment; the fiber ends are
provided with a depression so that the ferrules can be butted against each other
• Features of high-speed, low-loss optical cable (A66L-6001-0049#~)
The type of optical fiber used for a high-speed, low-loss optical cable has optical properties different
from that of conventional PCF optical cables (A66L-6001-0026 and A66L-6001-0029) to support
high-speed, long-distance communication. They are different in how the light propagates within
the fiber. Relaying different types of optical fibers may increase repeater loss, resulting in an
optical communication failure.
• When using a low-loss optical relay adapter, be sure to use the same type of optical cable
(high-speed, low-loss optical cables or low-loss optical cables).
• Colors of low-loss optical relay adapter and low-loss optical cable (distinguishing them from
conventional products)
While the color of the body of the conventional optical relay adapter is black, that of the low-loss
optical relay adapter is blue. While the color of the protection cover (Refer to above figure) of the
conventional PCF optical cable is black, that of the low-loss optical cable is blue.

(8) Installing the optical fiber junction adapter

The optical fiber junction adapter should be installed within a cabinet, as a rule. If it is impossible to
avoid installing it within a cabinet, protect the adapter and the optical cable portions (such as connectors
and cords) not covered with reinforcement coating from the outside air by, for example, covering them
with packing.

(9) Environmental resistance of the optical fiber junction adapter

• The optical fiber junction adapter is not waterproof. Even when optical cables are attached to both
ends of the adapter, there are very small gaps in the linked portions, so water resistance can not be
expected.

- 432 -
B-64303EN/03 APPENDIX D.OPTICAL FIBER CABLE

• When optical cables are attached to both ends of the junction adapter installed in a normal
environment (such as within a cabinet), it is unlikely that dust will penetrate between the adapter
and optical fiber to the degree that it may hamper normal optical linkage. If one or both ends of the
adapter are left open, dust and dirt may accumulate even when the adapter is in a normal
environment (such as within a cabinet). The dust and dirt on the adapter ends is likely to hamper
normal optical linkage when the optical cables are attached. In such a case, clean the junction
adapter and the optical connector using the optical fiber junction adapter cleaning method described
below.
• Do not allow cutting fluid to splash over the adapter or those optical cable portions (such as
connectors and cords) that are not covered with reinforcement coating. If the inside of the adapter
and fiber end surfaces are contaminated with cutting fluid, a malfunction may occur.

(10) Cleaning
If the optical fiber junction adapter, optical-to-electrical conversion module, or optical cable are soiled,
clean them according to the following procedures.
• Cleaning the optical fiber junction adapter and optical-to-electrical conversion module
First, clean the entire housing by wiping it with a cloth moistened with, or by washing it in, ethyl
alcohol. Similarly, wash the two sleeves in the adapter or wipe them with a cotton swab or the like.
• Cleaning optical cables
For the optical cables, it is important to clean the connectors at their ends. Any soiling on the
optical fiber end surfaces will hamper optical transmission, resulting in a malfunction. Wipe the
optical fiber end surfaces (that is, the ferrule end surfaces) thoroughly with a soft, clean cloth (like
gauze) moistened with ethyl alcohol, in the same way as described above. The use of cotton swabs
may prove convenient. The fiber end surfaces of low-loss optical cables are lower than the ferrules.
To remove any soiling from the fiber end surfaces completely, push the cotton swab or gauze into
the depressions all the way through while rotating the ferrule.
If the ferrules and optical connectors are contaminated with oily substances, and they may extend
over a cleaned fiber end surface when it is attached to the optical-to-electrical conversion module, it
is a good idea to wash them before wiping the optical fiber end surfaces, using the procedure stated
above.

E LIQUID CRYSTAL DISPLAY (LCD)

LCD with a touch panel
The touch panel is operated by directly touching the LCD screen. For this operation, be sure to use a
FANUC-supplied pen (A02B-0236-K111) dedicated to the touch panel. If a sharp-pointed pen is used,
for example, to touch the LCD screen, the LCD surface may be flawed or damaged. Moreover, do not
touch the LCD screen directly with a finger. Otherwise, the operability of the LCD may deteriorate, and
the LCD screen may get dirty.

Protection sheet for the touch panel

A protection sheet is attached the face of an LCD with a touch panel to protect the thin film of the touch
panel and LCD. If the protection sheet is damaged, it can be replaced. For the replacement method,
refer to the maintenance manual. (The protection sheet is a consumable part.)

B-64303EN/03 APPENDIX F.MEMORY CARD INTERFACE

F MEMORY CARD INTERFACE

Overview
The LCD-mounted type can input and output data within the CNC using the memory card interface on the
left side of the LCD, and edit or execute a machine program in the CF card inserted into the memory card
interface.
The stand-alone type can input and output data within the CNC using the memory card interface of the
control unit. (The stand-alone type cannot edit or execute a machine program in the CF card inserted
into the memory card interface.) For an explanation of remote diagnosis using a modem card, see the
related document.

CF card
Since a CF card includes flash memory, if read operation is repeated over a long period of time, an data
error occurs in some rare cases due to internal data corruption. Commercial CF cards generally do not
sufficiently address such a data error. In addition, read operation may take much time depending on the
state of internal memory; if there is a delay in transferring data to the CNC during DNC operation, the
finished quality of the machined surface may be affected.
The CF cards recommended below have a superior capability of correcting data automatically and are
designed so as not to read incorrect data even if a data error occurs. If these cards are used under the
machining conditions defined below, the finished quality of the machined surface is not affected.

Notes on DNC operation and memory operation using a memory card

attached to the memory card interface
Since a CF card includes flash memory, if read operation is repeated over a long period of time, an data
error occurs in some rare cases due to internal data corruption.
This CF card has a capability of correcting data automatically and is designed so as not to read incorrect
data even if a data error occurs, but it temporarily takes much time.
The delay in read operation affects the performance (speed) of DNC operation and memory operation and
the finished quality, so this must be considered while the use conditions are determined. Set the
processing time for one block to 4 ms or more.
When high performance is required or an expensive workpiece is machined, use the data server (DNC
operation). In DNC operation on the data server, the above delay in read operation does not affect the
performance or finished quality.
Use ISO code as format of NC program.

NOTE
If the cable is connected to JA4L when the separate absolute pulse coder
battery case contains the battery, the battery voltage is applied to the battery
power supply pin (+6 V) for each of the feedback connectors (JF101L to
JF104L). In this case, if the battery line and 0 V are short-circuited, the battery
may heat up or the protection circuit within Analog servo adapter may fail. First,
make sure the battery case contains no battery or the cable is not connected to
JA4L. Then, complete all cabling work and confirm cables are correctly
connected. Finally, place the battery or connect the cable to JA4L.

G.5.2.5 Detail of signals

(1) VCMD,EC (output)
VCMD and EC are the speed command signals for the servo amplifier. The voltage of VCMD with
respect to EC represents the speed command voltage. (The speed command voltage is enabled only
while the *ENBL signal is on.)

Electrical characteristics
Output voltage: -10V to +10V
Output current: 2mA
Output impedance: 100Ω

- 443 -
G.ANALOG SERVO ADAPTER APPENDIX B-64303EN/03

(2) *ENBL (output)

*ENBL is the enable signal for the servo amplifier. While this signal is on (connected to OV), the
VCMD signal is enabled. *ENBL is open collector.

Analog servo adapter

*ENBL

Input ON : connecting 0V Servo amplifier

Semiconductor Input OFF : open
contact 0V

Electrical characteristics
Maximum load current when output is on: -10V to +10V
Maximum output voltage when output is on: 6IL (VOlt), where IL: Load current
Withstand voltage when output is of: No more than 24V, including momentary values
Leakage current when output is of: No more than 100μA

(3) OVL (input)

OVL is the overload alarm signal issued by the servo amplifier. When this signal enters the release
state (high level), the CNC assumes that the servo system has entered the overload state, and turns
off the *PRDY and *ENBL signals for the axis. If this signal is not used, connect OVL and 0V to
each other (low level).
When an overload alarm is issued, the servo amplifier must stop the motor regardless of the state of
the VCMD signal.

minus sign (–) represents the direction of flow from the receiver.
- 444 -
B-64303EN/03 APPENDIX G.ANALOG SERVO ADAPTER

NOTE
The input release state is also assumed to be the high level.

(4) *PRDY (output)

*PRDY is the ready signal, issued by the CNC to the servo amplifier. The electrical characteristics
of this signal are the same as those of *ENBL.

(5) *VRDY (input)

*VRDY is the ready signal issued by the servo amplifier. When the power to the servo amplifier is
turned on to set the normal startup state, and the *PRDY signal from the CNC is subsequently turned
on, the servo amplifier must immediately turn on (short–circuit) the *VRDY signal. If the servo
amplifier encounters an error, the *VRDY signal must be turned off (released) to report the error to
the CNC. If this signal is not used, connect *VRDY and 0V to each other (low level), and set bit 1
(CVR) of parameter No. 1800 to 1.
If the servo amplifier encounters an error, stop the motor regardless of the state of the VCMD signal.
The electrical characteristics of this signal are the same as those of *ENBL.

(6) A, *A, B, *B, Z, *Z

These signals are received from the Pulsecoder.

・ A–phase and B–phase signals (A, *A, B, *B)

The A–phase and B–phase signals are shifted by 90 degrees relative to each other, and are used to
transfer incremental position information. A position is detected, assuming that the direction of
movement is positive while the B–phase signal is advanced, or that the direction of movement is
negative while the A–phase signal is advanced.

A phase signal
Shift in plus direction

B phase signal

A phase signal
Shift in minus direction

B phase signal

The differential input signals shown below are applied to the connectors. The time duration, TD,
from point α where the relative potential difference between A and *A becomes 0.5 V or more, to
point β where the relative potential difference between B and *B becomes 0.5 V or less, must satisfy
the condition indicated below. (This condition may restrict the maximum speed of movement.)

- 445 -
G.ANALOG SERVO ADAPTER APPENDIX B-64303EN/03

• Z–phase signal input

The Z–phase signal (one–rotation signal) requires a signal width of no less than quarter period of the
A–phase or B–phase signal. If the motor does not have this signal, ensure that the machine supplies
this signal. An absolute pulse coder supports the following reference position setting modes, which
do not use the Z–phase signal:
1) External reference position setting
2) Butt–type reference position setting

• Input voltage requirments

The voltage of A and B phase signals must meet the following requirments
High level: 2.4V or more
Low level: 0.8V or less

G.10 NOTICE

• The maximum number of interface units like Analog servo adapter or a separate detector interface
unit that can be connected to one FSSB line is two.
When Analog servo adapter is connected to the FSSB line, the number of the separate detector
interface unit can be connected to the same FSSB line is one.

• Analog servo adapter has four encoder interfaces. The unused one can be used for full closed
control.

• Analog servo adapter does not apply “CE Marking”.

- 453 -
G.ANALOG SERVO ADAPTER APPENDIX B-64303EN/03

• When system alarm is occurred on CNC or communication alarm between CNC and Analog servo
adapter is occurred, the signals *ENBL and *PRDY will be OFF. When the power of CNC or
Analog servo adapter is turn off, the signals *ENBL and *PRDY will be OFF.

• The way to install this unit is similar to the one of the separate detector interface unit. Please refer to
the Section 7.2.

• The sequence of power on/off is similar to the separate detector interface unit. Refer to the
Subsections 4.2.3 and 4.2.4. But if the position feedback with A quad B interface is used and the
+5VDC power is not supplied to it from Analog servo adapter, it is necessary to turn on the power
for it before the power for Analog servo adapter is turned on. Furthermore, in this situation, it is also
necessary that the A quad B interface signals of the separate detector become stable before turning
on Analog servo adapter.

G.11 PARAMETER SETTING

(1) At emergency stop, turn on the power of CNC.

(2) Follow the procedure below to set parameters concerned with FSSB.

In the case of using Analog servo adapter, the FSSB automatic setting function is not available. It is
necessary to set the value of No.1023, No.1815, No.1905, No.14340 to14349, No.14376 to 14391
and No.1936 to 1937 in the manual setting No.2 mode. Refer to “FSSB setting” of the connection
manual (function edition) about the detail of the setting.
When this parameter is set, Analog servo adapter is basically treated in the similar way to the
separate type detector interface unit. (After this, Analog servo adapter and the separate type detector
interface unit are called “an interface unit”.)
Follow the explanation below and the Parameter Manual (B-64310EN) of CNC and set the
appropriate value.

• Setting of servo axis number

No.
1023 Number of the servo axis for each axis

In case of using interface unit, set the value, which subtracts 1 from the connector number
of each axis. (In case of using Analog servo adapter, set 0 to 3 to the axes connected with
connector JV1nL to JV4nL.)
Set 0 to the axis without interface unit.
It is possible to use any connectors at any axis.

• Setting Address Conversion Table for slave number

No.
14340 ATR value corresponding to slave 01 on the FSSB line
to
14349 ATR value corresponding to slave 10 on the FSSB line

[Data type] Byte

[Valid data range] 0 to 7, 64, -56, -96
The amplifier or interface unit connected to CNC by the optical cable is called “Slave”.
Each one axis servo amplifier or one interface unit (with or without the additional unit)
consists of one slave. Two axes amplifier consists of two slaves and three axes amplifier
consists of three slaves.
The analog servo amplifier is numbered as if it was connected from the terminal slave
(the most far slave from CNC). Each one-axis analog servo amplifier is numbered one
slave number. For example, if the terminal unit connected to FSSB is slave 5, the analog
servo amplifiers are numbered from 6. (Refer to the example described later.)
This parameter is set as follows.

- In case of amplifier (including analog amplifier):

Set a value obtained by subtracting 1 from the setting of parameter No.1023 for the
axis to which the amplifier is assigned.

- In case of interface unit:

Set 64 for 1st interface unit and set -56 for the 2nd interface unit respectively.
Please see below figure.

[Valid data range] 0 to 7 and 32

No.
14384 ATR value corresponding to connector 1 on the 2nd interface unit
to
14391 ATR value corresponding to connector 8 on the 2nd interface unit

[Data type] Byte

[Valid data range] 0 to 7 and 32
Each of these parameters sets the value(ATR value) of the address translation table
corresponding to each connector on a interface unit.
In each of these parameters, set a value obtained by subtracting 1 from the setting of
parameter No.1023 for the axis connected to a connector on an interface unit.
When there is an axis for which bit 6 or 7 of parameter No.1905 is set to use an interface
unit, set 32 for those connectors that are not used.
