ENVIRONMENTAL REQUIREMENTS OUTSIDE THE CABINET
The peripheral units, such as the control unit and CRT/MDI, have been
designed on the assumption that they are housed in closed cabinets. In
this manual “cabinet” refers to the following:
Cabinet manufactured by the machine tool builder for housing the
control unit or peripheral units;
Cabinet for housing the flexible turnkey system provided by F ANUC;
Operation pendant, manufactured by the machine tool builder, for
housing the CRT/MDI unit or operator’s panel.
Equivalent to the above.
The environmental conditions when installing these cabinets shall
conform to the following table. Section 3.4 describes the installation and
design conditions of a cabinet satisfying these conditions.

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
CRT screen, noise resistance, and maintenance requirements must be
considered. The cabinet design must meet the following conditions :
D 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 designed for the servo amplifier and
servo transformer provided that they :
- Use an air filter on the air inlet ;
- Place the ventilating fan so that it does not blow air directly toward
the unit;
- Control the air flow so that no dust or coolant enters the air outlet
D 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 Section 3.5 for the details on thermal design of the cabinet.
D 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 adheres to the unit. This may cause the unit to fail.
D For the air to move easily , a clearance of 100 mm is required between
each unit and the wall of the cabinet.
D Packing materials must be used for the cable port and the door in order
to seal the cabinet.
Because the CR T unit uses a voltage of approximately 11 kV, airborne
dust gathers easily . If the cabinet is insufficiently sealed, dust passes
through the gap and adheres to the unit. This may cause the insulation
of the unit to deteriorate.
D The CRT/MDI unit must be installed in a location where coolant
cannot be poured directly on it. The unit does have a dust–proof front
panel.
D 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 3.7 for details of noise
elimination/management.
D The units must be installed or arranged in the cabinet so that they are
easy to inspect and maintain.

B–62753EN/01
3. INSTALLATION
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 CR T display and the magnetic sources generally 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.
The installation conditions of the I/O unit must be satisfied.
T o obtain good ventilation in the module, the I/O unit must be installed
in the direction shown in the following figure. Clearances of 100 mm
or more both above and below the I/O unit are required for wiring and
ventilation.
Equipment radiating too much heat must not be put below the I/O unit.

THERMAL DESIGN OF THE CABINET
3.5.1
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:
Internal heat loss P [W]
6[W/m
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.

⋅°C] × surface area S[m2]×10[°C] of rise in temperature
2
, the temperature of the air in the

has a cooling capacity
3.5.2
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 enlarges
the surface area. Section 3.7 explains five heat exchangers supplied by
FANUC. Select one of these according to the application.
If cooling fin A is used for the cabinet, the total cooling capacity of a
cabinet having a surface area of 4 m
as follows :
6W/m
The calculated value verifies that even if the internal heat is 320 W, the
temperature rise can be limited to less than 10°C.
See Section 3.6 for installing the heat exchanger.

The cooling fin can be installed in two ways, as shown in Fig.3.6.1(b).
The following lists the general precautions to be observed when using the
cooling fins :
D The fans are not included with the cooling fin. They should be
provided by the machine tool builder.
D Bring in the outside air from the bottom and exhaust the hot air from
the top.
D The inside air may flow from top to bottom or bottom to top. However,
generally decide the direction as follows :
- Bring in the air near high heat loss components.
- Exhaust the air toward the most important components to be
cooled.
D For the cooling fin to display the specified cooling capacity, the air
inside the cooling fins must flow at a velocity of 2.5 m/sec or greater.
(velocity of air flow measurement)

Set the slit to the intake side and
measure the velocity at the slit.
3. INSTALLATION
B–62753EN/01
Generally , install the cooling fins to the door. But be sure that the door
does not bend when installing the cooling fin. The cooling fins are
equipped with packing.

Installation
Specifications
The heat pipe type heat exchanger is used for cooling the airtight cabinet
of small sized electronic devices. It is a compact, lightweight, and
heat–efficient unit. Because the fan is built–in, it is used simply by
installing it, performing the ”panel cut’ operation.

3. INSTALLATION
Installation method
Please install the heat exchanger by the following sequence:
1 T ake out the external fan unit from the heat exchanger main unit. (Fig.
1)
Detach the external fan unit installation screws A (2 pieces), take out
the unit from the main unit by sliding it down, and detach the earth
cable and the power cable to the fan. Also detach the installation screw
B (1 piece).
2 Install the heat exchanger main unit in the installation section which
has been panel cut. (Fig. 2)
When fastening down the heat exchanger main unit with the screws,
first, temporarily secure the panel and the heat exchanger main unit
with the installation screw B, which was taken out in 1). After that,
secure the main unit by the installation screws. In this case, the
external fan unit installation screw holes should be aligned with the
main unit screw holes. (Please provide the installation screws for the
heat exchanger main unit.)
Because this product is composed of plastic, set the value shown
below for the screw tightening torque.
Heat exchanger main unit (M4 screw) : 11 kgf.cm
External fan unit (M3 screw) : 5 kgf.cm
3 Connect the power cable and the earth cable to the external fan unit (the
unit detached in 1), and secure the installation screw A to the main unit
from the outside.
The installation is now complete.

ACTION AGAINST NOISE
3.7.1
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.

Ground
The following ground systems are provided for the CNC machine tool:
Signal ground system (SG)
The signal ground (SG) supplies the reference voltage (0V) of the
electrical signal system.
Frame ground system (FG)
The frame ground system (FG) is used for safety, and suppressing
external and internal noises. In the frame ground system, the frames,
cases of the units, panels, and shields for the interface cables between
the units are connected.
System ground system
The system ground system is used to connect the frame ground
systems connected between devices or units with the ground.

Connect the signal ground with the frame ground (FG) at only one
place in the CNC control unit.
The grounding resistance of the system ground shall be 100 ohms or
less (class 3 grounding).
The system ground cable must have enough cross–sectional area to
safely carry the accidental current flow into the system ground when
an accident such as a short circuit occurs.
(Generally, it must have the cross–sectional area of the AC power cable
or more.)
Use the cable containing the AC power wire and the system ground
wire so that power is supplied with the ground wire connected.
