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.

Ground
The following ground systems are provided for the CNC machine tool:
(1)Signal ground system (SG)
The signal ground (SG) supplies the reference voltage (0 V) of the
electrical signal system.
(2)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.
(3)System ground system
The system ground system is used to connect the frame ground
systems connected between devices or units with the ground.

D Connect the signal ground with the frame ground (FG) at only one
place in the CNC control unit.
D The grounding resistance of the system ground shall be 100 ohms or
less (class 3 grounding).
D 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–sec tional area of the AC power cable
or more.)
D Use the cable containing the AC power wire and the system ground
wire so that power is supplied with the ground wire connected.

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) :

Use a CR–type noise eliminator. Varistor–type noise

Cable Clamp and
Shield Processing
The CNC cables that require shielding should be clamped by the method
shown below. This cable clamp treatment is for both cable support and
proper grounding of the shield. To insure stable CNC system operation,
follow this cable clamp method.
Partially peel out the sheath and expose the shield. Push and clamp by
the plate metal fittings for clamp at the part. The ground plate must be
made by the machine tool builder, and set as follows :
