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 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.

DThe cabinet to hold the control unit must be designed to maintain a difference in temperature of up to 10°C between the air in the cabinet and the outside air when the temperature in the cabinet rises.

For details of the thermal design, see 3.4.

DA closed cabinet must be equipped with a fan to circulate the air within. (This is not necessary for a unit with fan.)

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. (This is not necessary for a unit with fan.)

DPacking materials must be used for the cable port and the door in order to seal the cabinet.

DThe LCD unit and MDI unit must not be installed in such a place that coolant would directly fall onto the unit.

The front panels of the LCD unit and the MDI unit are dustproof. However, avoid installing the units in locations where their front panels directly receive coolant. For an explanation of the dust protection measures for the power magnetics cabinets and pendant boxes of machine tools, see Section 3.4.

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 3.6 for details of noise elimination/management.

DWhen determining the layout of units in the cabinet, consider maintainability; arrange the units in such a way that they can be easily replaced during maintenance and inspection.

DThe hard disk drive and floppy disk drive must not be installed near the source of a strong magnetic field.

DThe installation conditions of the I/O unit and connector panel I/O module must be satisfied.

To obtain good ventilation in the module, the I/O unit and connector panel I/O module 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 and connector panel I/O module.

DIf the CNC unit is installed at an altitude of over 1,000 m, an upper limit is placed on the ambient temperature (one of the environmental

conditions described in Section 3.1) for the CNC within the cabinet. Each increment of 100 m over 1,000 m requires that 1.0°C be subtracted from the maximum allowable ambient temperature for the CNC in the cabinet.

Example) If a cabinet containing the CNC is installed at an altitude

of 1,750 m, the maximum allowable ambient temperature for the CNC is: 55°C – 750/100 × 1.0°C = 47.5°C

The allowable ambient temperature range for the CNC is therefore from 0°C to 47.5°C.

If the hard disk drive in the CNC is used, the CNC can be installed only at an altitude ranging from:

–60 to 3,000 m when in operation –60 to 12,000 when not in operation

DUnspecified frequencies may cause the CNC control unit and hard disk drive to vibrate at their resonance frequency, possibly subjecting unit components to an acceleration higher than allowable. After mounting the CNC control unit on your machine, carefully check for any abnormal conditions.

CAUTION

For a control unit with a hard disk, data stored on the hard disk may be destroyed due to operator errors or accidents even when the environmental conditions above are satisfied. To guard against such data loss, back up the important hard disk data regularly. In particular, never turn off the power, even momentarily, while the hard disk is being accessed or the operating system is running, as doing so is highly likely to destroy part of the contents of the disk. End users should be made fully aware of this, to ensure that they do not inadvertently lose important data.

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	The cooling capacity of a cabinet made of sheet metal is generally 6 W/°C
	Temperature Rise	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
	within the Cabinet
		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] x
		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	If the temperature rise cannot be limited to 10°C by the cooling capacity
	Cooling by Heat	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
	Exchanger
		the cooling fin to obtain effective cooling. The heat exchanger enlarges
		the surface area.
		Example
		For a cabinet with a surface area of 4 m2, if a heat exchanger with a heat
		radiation capacity of 9 W/°C is used, the total heat radiation capacity
		increases to
		6W/m2 °C × 4m2 + 9W/°C = 33W/°C
		This means that even if the internal heat generation is 320 W, the
		temperature rise is held below 10 °C.

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.

3.6.1

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.
