DESIGN AND INSTALLATION CONDITIONS OF THE MACHINE TOOL MAGNETIC CABINET

When a cabinet is designed, it must satisfy the environmental conditions
described in Sec. 3.1. In addition, the magnetic interference on the CR T
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.

Cabinets that let in air may be desined for the servo amplifier and servo

transformer provided that they :

D Use an air filter on the air inlet ;

D Place the ventilating fan so that it does not blow air directly toward

the unit;

D Control the air flow so that no dust or coolant enters the air outlet
(2)The cabinet must be designed to maintain a difference in temperature

of 10°C or less between the air in the cabinet and the outside air when

the temperature in the cabinet increases.

See Sec. 3.4 for the details on thermal design of the cabinet.
(3) A closed cabinet must be equipped with a fan to circulate the air

within.

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
abheres to the unit. This may cause the unit to fail.

(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

oreder to seal the cabinet.

Because the CRT unit uses a voltage of approximatery 1 1 kV, airborne

dust gathers easily. If the cabinet is insufficiently sealed, dust passes

through the gap and abheres to the unit. This may cause the insulation

of the unit to deteriorate.
(6)The display unit and other display units must be installed in a location

where coolant cannot be poured directly on it. The unit does have a

dust–proof front panel.
(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 Sec. 3.5 for details of noise

elimination/management.
(8)The units must be installed or arranged in the cabinet so that they are

easy to inspect and maintain.

3. INSTALLATION

B–63503EN/01

(9)The CRT screen can be distorted by magnetic interference.

Arranging magnetic sources must be done with care.

If magnetic sources (such as transformers, fan motors,

electromagnetic contactors, solenoids, and relays) are located near the

CRT display, they frequently distort the display screen. To prevent

this, the CRT display and the magnetic sources generatlly must be kept

300 mm apart. If the CRT display and the magnetic sources are not

300 mm apart, the screen distortion may be suppressed by changing

the direction in which the magnetic sources are installed.

The magnetic intensity is not constant, and it is often increased by

magnetic interference from multiple magnetic sources interacting

with each other . As a result, simply keeping the CR T and the magnetic

sources 300 mm apart may not be enough to prevent the distortion.

If they cannot be kept apart, or if the CRT screen remains distorted

despite the distance, cover the screen with a magnetic shield.

THERMAL DESIGN OF THE CABINET

3.4.1

Temperature Rise
Within the Cabinet

The purpose of the thermal design of the cabinet is to limit the difference
in temperature between the air in the cabinet and the outside air to 10°C
or less when the temperature in the cabinet increases.
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.

The cooling capacity of a cabinet made of sheet metal is generally 6 W/°C
per 1m
cabinet having a surface area of 1 m
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.
The following expression must then be satisfied to limit the difference in
temperature between the air in the cabinet and the outside air to 10°C or
less when the temperature in the cabinet rises:

For example, a cabinet having a surface area of 4m
of 24W/°C. T o limit the internal temperature increase to 10°C under these
conditions, the internal heat must not exceed 240W. If the actual internal
heat is 320W, however, the temperature in the cabinet rises by 13°C or
more. When this happens, the cooling capacity of the cabinet must be
improved using the heat exchanger described next.

Cooling by Heat
Exchanger

If the temperature rise cannot be limited to 10°C by the cooling capacity
of the cabinet, a heat exchanger must be added. The heat exchanger
forcibly applies the air from both the inside and outside of the cabinet to
the cooling fin to obtain effective cooling. The heat exchanger enlar ges
the surface area.

ACTION AGAINST NOISE

3.5.1

Separating Signal
Lines

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.

The cables used for the CNC machine tool are classified as listed in the
following table:

Process the cables in each group as described in the action column.

Noise Suppressor

Notes on selecting the
spark killer

The AC/DC solenoid and relay are used in the power magnetics cabinet.
A high pulse voltage is caused by coil inductance when these devices are

turned on or off.
This pulse voltage induced through the cable causes the electronic circuits

to be disturbed.

D Use a spark killer consisting of a resistor and capacitor in series. This

type of spark killer is called a CR spark killer.(Use it under AC)

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

but cannot suppress the sudden rise of the pulse voltage. FANUC

therefore recommends a CR spark killer.)
D The reference capacitance and resistance of the spark killer shall

conform to the following based on the current (I (A)) and DC

resistance of the stationary coil:

1) Resistance (R) : Equivalent DC resistance of the coil

2) Capacitance (C) :

Procedure for Turning
On the Power

Turn on the power to each unit in the following order or all at the same
time.

1. Power supplies (200 VAC) for the entire machine

2. Power supplies (24 VDC) for slave I/O devices connected
using the FANUC I/O Link

3. Power supplies (24 VDC) for the control unit and CRT unit

Do not disconnect the battery for memory backup (3 VDC) or the battery
for the separate absolute pulse coders (6 VDC) regardless of whether the
power to the control unit is on or off. If batteries are disconnected when
the power to the control unit is turned off, current data stored in the control
unit for the pulse coders, parameters, programs etc, are lost.

Make sure that the power to the control unit is on when replacing batteries.
See Section 4.4.1 for how to replace the batteries for memory backup.

CAUTION

The maintenance rotary switch must be always set to 0 (set
to 0 at shipping from factory).
Changing this setting may cause the contents of memory to
be lost.

4.2.4

Procedure for Turning
Off the Power

Turn off the power to each unit in the following order or all at the same
time.

1. Power supplies (24 VDC) for slave I/O devices connected
using the FANUC I/O Link

2. Power supplies (24 VDC) for the control unit and CRT unit

3. Power supplies (200 VAC) for the entire machine

Motors cannot be controlled when the power is turned off or momentarily
interrupted. Take appropriate action on the machine side when necessary .
For example, when the tool is moved along a gravity axis, apply brakes
to prevent the axis from falling. Apply a brake that clamps the motor
when the servo is not operating or the motor is not rotating. Release the
clamp only when the motor is rotating. When the servo axis cannot be
controlled when the power is turned off or momentarily interrupted,
clamp the servo motor . In this case, the axis may fall before the relay for
clamping starts operating. The designer should make sure if the distance
results in trouble.

BATTERY

B–63503EN/01

4.4.1

Battery for Memory
Backup (3VDC)

Part programs, offset data, and system parameters are stored in CMOS
memory in the control unit. The power to the CMOS memory is backed
up by a lithium battery mounted on the front panel of the control unit. The
above data is not lost even when the main battery goes dead. The backup
battery is mounted on the control unit at shipping. This battery can
maintain the contents of memory for about a year.
When the voltage of the battery becomes low, alarm message “BAT”
blinks on the CRT display and the battery alarm signal is output to the
PMC. When this alarm is displayed, replace the battery as soon as
possible. In general, the battery can be replaced within two or three
weeks, however, this depends on the system configuration.
If the voltage of the battery becomes any lower, memory can no longer
be backed up. T urning on the power to the control unit in this state causes
system alarm 910 (SRAM parity alarm) to occur because the contents of
memory are lost. Clear the entire memory and reenter data after replacing
the battery.The power to the control unit must be turned on when the
battery is replaced. If the battery is disconnected when the power is turned
off, the contents of memory are lost.
Observe the following precautions for lithium batteries:

WARNING

If an unspecified battery is used, it may explode.
Replace the battery only with the specified battery
(A02B–0177–K106.)

Replacing the battery

Dispose of batteries used in accordance with the applicable laws of your
country or the applicable laws or regulations of your local self–governing
body. Before disposal, insulate the terminals with tape or something
similar to prevent them from being short–circuited.

1 Use a litium battery (ordering drawing number :

A02B–0177–K106)
2 Turn on the Series 0i.
3 Remove the battery case from the front panel of the power supply unit.

The case can be removed easily by holding the top and bottom of it and

pulling.

Battery for Separate
Absolute Pulse Coders
(6VDC)

One battery unit can maintain current position data for six absolute pulse
coders for a year.
When the voltage of the battery becomes low , APC alarms 3n6 to 3n8 (n:
axis number) are displayed on the CRT display. When APC alarm 3n7
is displayed, replace the battery as soon as possible. In general, the battery
should be replaced within two or three weeks, however, this depends on
the number of pulse coders used.
If the voltage of the battery becomes any lower , the current positions for
the pulse coders can no longer be maintained. Turning on the power to
the control unit in this state causes APC alarm 3n0 (reference position
return request alarm) to occur. Return the tool to the reference position
after replacing the battery .See Subsec. 7.1.3 for connecting the battery for
separate absolute pulse coders.

CONNECTING I/O DEVICES

B–63503EN/01

5.3.1

General

I/O devices are used for inputting various data such as CNC programs and
parameters from external devices to the CNC or outputting data from the
CNC to external devices.
The Handy File is one of the I/O devices for the Series 0i. The interface
for I/O devices complies with RS–232–C. The Series 0i can therefore be
connected to devices which have an RS–232–C interface.

This signal is set to on when NC
starts sending data and is turned off
when transmission ends.

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

When external device is ready to op­erate, this signal is set. This signal
should usually be connected to the
signal indicating external device pow­er supply being on. (ER signal of ex­ternal device). See Note below.
The NC transfers data when this sig­nal is set. If the signals turned off dur­ing data transfer , alarm 086 is issued.
If the DR signal will not be used,
make sure to strap this signal circuit
to the ER signal circuit.

Codes

Generally , two transmission methods are available at the serial interface.
Series 0i use the start–stop method. With this method, start and stop
signals are output before and after each data bit.

(8 bit including one parity bit)

Data bit

Stop bits
(2 bits)

Transmission codes are as follows:
(i) EIA code and Control codes DC1 to DC4.
(ii) ISO code and Control codes DC1 to DC4 (Optional ISO code input

is necessary.)

The connected external device must be able to recognize the following
control codes, sent from NC.

Control code 8 7 6 5 4 3 2 1

DC1 Tape reader start f d f
DC2 Tape punch designation f d f
DC3 Tape reader stop f f d f
DC4 Tape punch release f d f f

NOTE

The listed control codes are used for both EIA and ISO.

In this interface, control codes DC1 to DC4 are used.
(a) NC can control external device by issuing codes DC1 to DC4.
(b) When external processing falls behind the pace of the NC signals

(When NC issues data)

(i) External device can temporarily stop NC data output by using

the NC’s CS signal. Data output stops within two characters
including a currently transmitting character when CS OFF
signal is input to NC. When CS signal is turned on again, data
transmission start.

(ii) If control code DC3 is input to NC, NC stops data output within

ten characters. When control code DC1 is input to NC, NC
starts sending data again.

(c) When the external device is equipped with an ISO/EIA converter,

the external device must satisfy the specification shown in Table

5.3.4 (a).

Cable Length When
Only One Manual Pulse
Generator is Used

Manual pulse generators are supplied with 5 VDC power the same as
pulse coders. The drop in voltage due to cable resistance must not exceed

0.2V (on 0V and 5V lines in total).

R : Wire resistance per unit length [Ω/m]
m: Number of 0–V wires

(= number of 5–V wires)

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:

=76.75[m]

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.

NOTE

1 The total length of the cable between the CNC and amplifier

and that between the amplifier and motor shall not exceed
50m.

2 As the current feedback lines (IRn and ISn), use the middle

twisted pair of the recommended cable. If any other pair is
used, abnormal noise or oscillation may occur.

3 The servo interface of the Series 0i is type B. Use a servo

unit which supports the type–B interface. When using a
servo unit which supports both the type–A and type–B
interfaces, select the type–B interface. For details, refer to
the manual supplied with the servo unit. If the interface
setting is incorrect, a servo alarm (AL401 V READY OFF)
will be issued.

The standard of the feedback signal from the additional detector is as
shown below.

(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.

TD y 0.15 µsec

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 0.15 µs. The period and pulse
width of the signals must be long enough to satisfy the above
requirements.

GENERAL

The Series 0i has a built–in I/O board for machine interface I/O. Number
of DI/DO points for built–in I/O card are 96/64 points. 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.
MIL ribbon cable connectors are used as the internal connectors for the
built–in I/O board to simplify connection with the connector panel.

DI Signals and

8.2.2

DO Signals and Drivers

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

DI signals are basically of the sink type (a type that drains ener gy). 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.

The driver of DO signals is source type (a type that supplies energy).
If a system alarm occurs in a control unit of the Series 0i, all I/O board

drivers are turned off. Keep this in mind when setting up a machine
sequence.
The same situation can occur if the power to the control unit is turned of f
independently.

For address X1004, either a source or sink type (with a 0– or 24–V
common voltage) can be selected. COM4 must be connected to either 24
or 0 V; never leave it open. From the viewpoint of safety standards, it is
recommended that a sink type signal be used. The above diagram shows
an example in which the signal is of sink type (with a 24–V common
voltage).
