LIQUID CRYSTAL

DISPLAY (LCD)

Brightness of the

When the ambient temperature is low, the brightness of the LCD

monochrome LCD

decreases.

(The LCD screen is dark particularly immediately after the

power is turned on.) This phenomenon is not a failure but is a property

specific to the LCD. When the ambient temperature increases, the LCD

screen becomes brighter. The monochrome LCD has a brightness control

function. For the method of adjustment, see Section 1.17.

LCD with a touch panel

The touch panel is operated by directly touching the LCD screen. For this

operation, be sure to use a FANUC-supplied pen (A02B-0236-K111)

dedicated to the touch panel. If a sharp-pointed pen is used, for example,

to touch the LCD screen, the LCD surface may be flawed or damaged.

Moreover, do not touch the LCD screen directly with a finger. Otherwise,

the operability of the LCD may deteriorate, and the LCD screen may get

dirty.

Protection sheet for the

A protection sheet is attached the face of an LCD with a touch panel to

is damaged, it can be replaced.

Before replacement

<1> Turn off the power to the machine.

<2> Peel off the old protection sheet from the surface of the touch

panel.

<3> Wipe off adhesive residue if any on the screen surface with

alcohol.

<4> Use the detergent to remove oil or dirt stuck to the surface of the

touch panel.

<5> With a soft, damp cloth, wipe off detergent completely.

D If the touch panel surface becomes cloudy, oil is still left on

the surface. Remove oil completely.

D If oil or detergent is left on the surface of the touch panel, the

protection sheet cannot adhere to the panel completely and

will sometimes peel off easily.

REPLACING FUSES

WARNING

ON VARIOUS UNITS

Before replacement of a blown fuse, the cause of the blown

fuse must be corrected. So, fuse replacement work must be

done only by a person who is trained in the related

maintenance and safety requirements. When opening the

cabinet and replacing a fuse inside, be careful not to touch

the high-voltage circuits (marked with

and fitted with an

insulating cover). Touching the uncovered high-voltage

circuits presents an extremely dangerous electric shock

hazard.

For the specification of the fuse of each unit, see the list of consumables

The CNC is becoming increasingly smaller as the surface mount

5.8

technology and custom LSI technology advance.

COUNTERMEA-

SURES AGAINST

In many cases, as the CNC becomes more compact, the mounting

locations of its constituent units become closer to a noise source in the

NOISE

power magnetics cabinet.

In general, noise is generated by electrostatic coupling, electromagnetic

induction, or a grounding loop, and is induced into the CNC.

The CNC incorporates sufficient countermeasures against external noise.

However, it is difficult to measure the level and frequency of noise

quantitatively, and many unknown factors are involved. So, to improve

the operation stability of a CNC machine tool system, noise generation

must be minimized, and the induction of generated noise into the CNC

must be suppressed.

For design of equipment including a power magnetics cabinet, take these

countermeasures on the machine side against noise into consideration.

With a CNC machine tool, three ground systems are used.

Grounding

(1) Signal ground system (SG)

Signal ground (SG) provides a reference voltage (0 V) for the electric

signal system.

(2) Frame ground system (FG)

The purposes of frame ground (FG) are to ensure safety and to provide

shielding from external and internal noises. Specifically, the frames

of equipment, unit cases, panels, inter-unit interface cables, and so

forth are shielded.

(3) Protective earth (PE)

The protective earth (PE) is designed so that the protective grounds

provided between the units are connected to ground at one point from

a system point of view.

flows to the protective earth (PE) when an accident such as a short

circuit occurs.

(In general, a cross-sectional area equal to or greater

than that of the AC power line is required.)

integrated with an AC power line so that power is not fed when the

With a power magnetics cabinet, components such as an AC/DC solenoid

and AC/DC relay are used. When turned on and off, these components

Noise Suppressor

generate a high-energy pulse voltage due to coil inductance.

Such a pulse voltage is induced into cables, for example, and can interfere

with electric circuitry.

Notes on spark killer

D Select a CR-type spark killer (for use with AC circuitry) (A varistor

selection

has a function for clamping the peak voltage of a pulse voltage, but

cannot suppress a spike-like voltage. For this reason, the use of a

CR-type spark killer is recommended.)

it can be accessed from the back.

(2) Remove the connector for the lithium battery, then remove the battery

from the battery holder.

(3) Within five minutes, plug the connector (BAT1) for a new battery and

insert a new battery.

(4) Reinstall the CNC display unit with PC functions or the PANEL i.

(5) Turn on the power and make sure the BIOS parameter is not cleared

(no error occurs during startup).

When this procedure is used to replace the battery, normally the BIOS

settings are not cleared. However, in case the settings are cleared, the

following message appears during power up, the default BIOS settings

are loaded, and the unit automatically reboots.

251: System CMOS checksum bad - Default configuration used.

Therefore, check whether the default settings of the CNC display unit

with PC functions or the PANEL i are changed before maintenance. If the

settings are cleared to the defaults, restore the BIOS settings.

Replacing the Fuse

WARNING

Before replacing the fuse, eliminate the cause by which the

fuse blew.

Therefore, only those personnel who were well trained for

maintenance and safety can perform the replacement.

When replacing the fuse with the cabinet open, be careful

not to touch the part containing high-voltage circuits.

Otherwise, you receive an electric shock.

A fuse blows when there is a short circuit in the CNC display unit with

PC functions or the PANEL i. When the fuse blows, check the following

points.

S A conductive part touches the main printed circuit board.

S A PCI extension board failed or is incorrectly inserted.

S A cable is incorrectly connected.

When the fuse blows, the system may suffer damage. Before turning on

the power again, make visual and smell inspection to check the system for

an abnormality and replace the failed parts if any.
