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 CRT 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 :

DUse an air filter on the air inlet ;

DPlace the ventilating fan so that it does not blow air directly toward the unit;

DControl 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 11 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 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.

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.

	3.4.1	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 S @ °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.
	3.4.2	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.

	3.5	The CNC has been steadily reduced in size using surface–mount and
	ACTION AGAINST	custom LSI technologies for electronic components. The CNC also is
		designed to be protected from external noise. However, it is difficult to
	NOISE
		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.
	3.5.1	The cables used for the CNC machine tool are classified as listed in the
	Separating Signal	following table:

Be sure to perfrom shield processing in Subsec. 3.5.5.

NOTE

1The groups must be 10 cm or more apart from one another when binding the cables in each group.

2The electromagnetic shield refers to shielding between groups with grounded steel plates.

Ground

Notes on connecting the ground systems

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.

DThe grounding resistance of the system ground shall be 100 ohms or less (class 3 grounding).

DThe 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.)

DUse 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.

DUse 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.)

DThe 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

		I2		I2
	2) Capacitance (C) :		to		( F)
		10		20

I : Current at stationary state of the coil

Mount the noise eliminator near a motor or a relay coil.

NOTE

Use a CR–type noise eliminator. Varistor–type noise eliminators clamp the peak pulse voltage but cannot suppress a sharp rising edge.

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 :
