3.4 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 :
.
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 :
0
Use an air filter on the air inlet ;
0
Place the ventilating fan so that it does not blow air directly toward
the unit; 0 Control the air flow so that no dust or coolant enters the air outlet 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.
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/set 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.
For the air to move easily, a clearance of 100 mm is required between each unit and the wall of the cabinet.
Packing materials must be used for the cable port and the door in order to seal the cabinet. Because the CRT 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.
The CRT/MIX unit must be installed in a location where coolant cannot be poured directly on it. The unit does have a dust-proof front panel.
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 magnet& 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.
0
The units must be installed or arranged in the cabinet so that they are easy to inspect and maintain.

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 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 CRT 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.
To 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.

3.5 THERMALDESIGN
OFTHECABINET
3.5.1
Temperature Rise within the Cabinet
&-62443E/O2
purpose of the thermal design of the cabinet is to limit the difference
The
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 lm2 surface area, that is, when the 6W heat source is contained in a cabinet having a surface area of 1 mz, the temperature of the air in the cabinet rises by l°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
constantThe 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 m (
6w/m2 l
For example, a cabinet having a surface area of 4m2 has a cooling capacity
of 24W/“C. To limit the internal temperature increase to 10°C under these
conditions, the internal heat must not exceed 240W. If the actual internal
heat is 32OW, 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] X surface area S[m2] X lO[OC] of rise in temperature
3.5.2
Exchanger
If the temperature rise cannot be limited to 10°C by the cooling capacity
Heat Cooling by
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 rn? in the example above is improved as follows :
6W/m* l “C X 4m2 + 9.1WI°C= 33.1Wl°C
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.l(b). The following lists the general precautions to be observed when using the cooling fins :
The fans are not included with the cooling fin. They should be provided by the machine tool builder.
Bring in the outside air from the bottom and exhaust the hot air from the top.
The inside air may flow from top to bottom or bottom to top. However, generally decide the direction as follows :
0
Bring in the air near high heat loss components.
0 Exhaust the air toward the most important components to be
cooled.
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/set or greater.
(velocity of air flow measurement)
Set the slit to the intake side and
measure the velocity at the slit.
l 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 method
Please install the heat exchanger by the following sequence:
1 Take 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

3.7.1
Separating Signal
Lines
B-62443uo2
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
couplin
g,
electromagnetic induction, and ground
loops. When designing the power magnetics cabinet, guard against noise in the
machine as described in the following section.

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.
Use a spark killer consisting of a resistor and capacitor in series. This type of spark killer is called a CR spark killer.(Use it under AC) (A varistor is useful in clamping the peak voltage of the pulse voltage, but cannot suppress the sudden rise of the pulse voltage. FANUC therefore recommends a CR spark killer.)
The reference capacitance and resistance of the spark killer shall conform to the following based on the current (I (A)) and DC resistance of the stationary coil:

Battery for Memory Backup
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 one or two weeks, however, this depends on the system configuration. If the voltage of the battery becomes any lower, memory can no longer be backed up. Turning on the power to the control unit in this state causes system alarm 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:
Note
If an unspecified battery is used, it may explode. Replace the battery only with the specified battery
l A0250200-K102 for power supply Al and BI. l A02Eb0177.K106 for power supply C.
Dispose of used batteries as follows:

Procedure
for Turning
off 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 (such as the I/O Unit-MODEL A)
3 Power supplies (24 VDC) for the control unit and CRT unit
(200 VAC for the PDP 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 3.82 for how to replace the batteries for memory backup.
Turn off the power to each unit in the following order or all at the same
time.
1 Power supplies (24VDC) for slave I/O devices connected
using the FANUC I/O Link (such as the I/O Unit-MODEL A)
2 Power supplies (24 VDC) for the control unit and CRT unit
(200 VAC for the PDP 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 startsoperating. The designer should make sure if the distance results in trouble.

The CNC can be combined with the units shown in the table below as I/O
units for the machine interface. The I/O units can be classified into two types: the I/O units tailored to the FANUC I/O Link, and the built-in I/O unit. The I/O units for the FANUC I/O Link are installed separately from the control unit, and connected with the control unit using the dedicated serial FANUC I/O Link. As shown in the figure below, two or more units can be installed separately. By placing the interface unit and connection unit for the operator’s panel near the operator’s panel, an operator’s panel that
inputs/outputs many signals can be interfaced easily. The FANUC I/O Unit-MODEL A is a modular-type I/O unit. It selects necessary modules from various I/O modules provided by FANUC according to the application and uses them as one external unit. The FANUC I/O Link transfers data between the control unit and such an
external unit at a high speed. The states of the input signals from the
machine are transferred to the control unit at regular intervals. The states
of the output signals from the control unit are transferred to external units
at regular intervals. (Note that this manual covers only part of the uses
that the FANUC I/O Link has. For example, although it can be used for
connecting the l-axis CNC FANUC Power Mate or cell controller
FANUC F-D Mate, this manual does not mention it. This is because the
purpose of this manual is to describe the I/O units having machine
interface.) The built-in I/O unit is an I/O card to be inserted into a slot in the control
unit. Although the built-in I/O unit is less flexible than the FANUC I/O
Unit MODEL A, it is available in four types depending on the number of
DI/DO points.

C’ONNECTION OF THE FANUC I/O Link
CNC has two JDlA interface connectors for the FANUC I/O Link.
6.2.1 General
The
Only one of the two connectors is selected according to the type of PMC, and both are not used at the same time. For a system with a PMC-RB, the I/O Link is connected to the main CPU board. For a system with a PMC-RC, the I/O Link is connected to the option 3 board. Starting at this point (main CPU board or option 3 board), the I/O Link is connected with the I/O units and interface unit of the operator’s panel sequentially in a daisy-chain manner. In the I/O Link there are the master station and its slave stations. The master is the control unit of the CNC, and the slaves are the I/O unit and interface unit for the operator’s panel. The slaves are divided into groups, and up to 16 groups can be connected to one I/O Link. A maximum of two base I/O units can be connected as a group. The operator’s panel connection unit and interface unit for the operator’s panel are each counted as one group. The two connectors of the I/O link are named JDlA and JDlB, and are common to all units (that have I/O Link function). A cable is always connected from JDlA of a unit to JDlB of the next unit. of the last unit is not used and left open, it need not be connected with a terminator. The pin assignments of connectors JDlA and JDlB are common to all
units on the I/O Link, and are illustrated on the next page. Use the figures
when connecting the I/O Link irrespective of the type of unit.

Addresses in a module are defined relatively, with the beginning address as 0. Real addresses viewed by the sequence program of the PMC are set by the programmer. For input modules, an input signal becomes “1” when the contact point connected with the input is turned ON. For output modules, an output contact point (or transistor) is turned ON when the output signal is “1”.

As a result of the calculation above, when the number of input points is smaller than that of the output points in a single group, the number of input points is assumed to be equal to that of the output points.
Example 1:
When the following modules are used in the group No. 0
In this case, as the number of input points is smaller than that of the output points, the number of input points is assumed1 to be equal to that of the output points, in other words, 256 points.
