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 :

DThe 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

DThe 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.

DA 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.

DFor the air to move easily, a clearance of 100 mm is required between each unit and the wall of the cabinet.

DPacking 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.

DThe 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.

DNoise 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.

DThe 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 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.

THERMAL DESIGN OF 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.

3.5.1

e e e i e i i e i e

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.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/m2 °C] ×surface area S[m2]×10[°C] of rise in temperature

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 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.

3.5.2

i e c e

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 m2 in the example above is improved as follows :

6W/m2 °C × 4m2 + 9.1W/°C= 33.1W/°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.3.6.1(b). The following lists the general precautions to be observed when using the cooling fins :

DThe fans are not included with the cooling fin. They should be provided by the machine tool builder.

DBring in the outside air from the bottom and exhaust the hot air from the top.

DThe 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.

DFor 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.

B±62753EN/01	3. INSTALLATION
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
	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

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.

3.7.1

Separating Signal Lines

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.

Notes on connecting the ground systems

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.
