path on the screen.

In addition, it is also possible to enlarge/reduce the screen.

The drawing coordinates (parameter) and graphic parameters must be set

before a tool path can be displayed.

With two-path control, the tool paths of two tool posts are displayed on

the same screen, one on the right and the other on the left.

Graphics display procedure

Procedure

Set the drawing coordinates with parameter No. 6510 before starting

drawing. See

“Drawing Coordinate System” for the settings and

corresponding coordinates.

For the two-path control, parameter GRL (bit 0 of No. 6500) specifies

which tool post is displayed on which side (tool post 1 on the right or tool

post 2 on the right).

OPERATION

B-63524EN/01

GRAPHIC CENTER (X, Z), SCALE (S)

A screen center coordinate and drawing scale are displayed. A scale

screen center coordinate are automatically calculated so that a figure

set in WORK LENGTH (a) and WORK DIAMETER (b) can be fully

displayed on the screen. So, the user need not set these parameters

usually.

A screen center coordinate is defined in the workpiece coordinate

system. Table 12. 3. 2 indicates the unit and range. The unit of SCALE

is 0.001%.

PROGRAM STOP (N)

Set the sequence number of an end block when part of the program is

to be drawn. A value set in this parameter is automatically cancelled

(cleared to -1) once a drawing is provided.

AUTO ERASE (A)

1 is set, the previous drawing is automatically erased when

automatic operation is stated from the reset state. Then, drawing is

started.

LIMIT (L)

1 is set, the area of stored stroke limit l is drawn with

double-dot-and-dash lines.

DRAWING MODE (M)

Drawing mode is used for dynamic graphic display (supported for the

Super CAPi T). Usually, it does not need to be set.

NOTE

The parameter values for drawing are preserved even if

power is turned off.

D Executing drawing only

Since the graphic drawing is done when coordinate value is renewed

during automatic operation, etc., it is necessary to start the program by

automatic operation. To execute drawing without moving the machine,

therefore, enter the machine lock state.

D Deleting the previous

14. SCREEN HARDCOPY

SCREEN HARDCOPY

The screen hardcopy function outputs the information displayed on the

CNC screen as 640*480-dot bitmap data. This function makes it possible

to produce a hard copy of a still image displayed on the CNC.

The created bitmap data can be displayed on a PC.

Screen Hardcopy Procedure

Check the parameter settings. To use the screen hardcopy function,

set bit 7 of parameter 3301 to 1 and parameter 20 (I/O channel

selection) to 4 (memory card I/F). Set other relative parameters (bits

0, 2, and 3 of parameter 3301) as needed. In a multipath system, set

the parameters for each path.

Insert a memory card.

To start the function, set hardcopy start signal HDREQ (G67#7) to 1.

Alternatively, hold down the [SHIFT] key for five seconds.

To end the function, press the [CAN] key. Alternatively, set hard

copy stop signal HDABT (G67#6) to 1.

While the screen hardcopy operation is in progress, the hardcopy in

progress signal (F061#3) is tied to 1. For several tens of seconds (or

several seconds, for a monochrome LCD) before the hardcopy

operation ends, the screen image stands still.

When the screen hardcopy operation is completed, the hardcopy in

progress signal (F061#3) goes 0.

Supplementary

While the screen hardcopy operation is in progress, the screen image

explanation

keeps still. This means that the clock displayed on the screen indicates

the beginning and end of the operation. When the clock stops counting

seconds, the hard copy operation starts. The clock resumes counting

seconds when the screen hard copy operation ends.

801

14. SCREEN HARDCOPY

OPERATION

B-63524EN/01

NOTE

During the screen hardcopy operation, key input is disabled

for several tens of seconds. Until the screen hardcopy

operation ends, the screen image lies still. During this

period, the hardcopy in progress signal (F061#3) is tied to

1. No other signal is output. Avoid turning off the power

indiscriminately during that period.

If the [SHIFT] or [CAN] key is customized by C executor, for

instance, the screen hardcopy operation may disable the

[SHIFT] or [CAN] key.

A normal hard copy may not be produced while the screen

image is moving.

Limitations

A hard copy of the following screens cannot be produced.

Screen of the FS-160i/180i/210i (CNC with personal computer

function)

System alarm screen

Screen while RS-232-C is being used

Screen during automatic or manual operation (A hard copy can be

produced in a rest of the operation.)

File name

The bitmap files created by the screen hardcopy function are named as

follows, in order in which they are created after power-up:

‘HDCPY000.BMP’ (Name of the first hardcopy file created after

power-up)

‘HDCPY001.BMP’ (Name of the second hardcopy file created after

power-up)

‘HDCPY099.BMP’

NOTE

A screen hardcopy file produced after the file HDCPY099.

BMP is output will be named as HDCPY000.BMP.

If a BMP file output by the screen hardcopy function has the

same name as a file present on a memory card, the file on

the memory card is overwritten unconditionally.

When the hardcopy function is carried out after power is

turned off and on again, the first output file is named as

HDCPY000.BMP again. If the inserted memory card has a

file having the same name, the file is unconditionally

overwritten. Note this when continuously producing hard

copies of various screens.

Battery for memory

Part programs, offset data, and system parameters are stored in CMOS

backup

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.

Therefore, the above data is not lost even if the main battery fails. The

backup battery is installed in the control unit prior to being shipped from

the factory. This battery can provide backup for the memory contents for

about a year.

When the battery voltage falls, alarm message “BAT” blinks on the LCD

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 of the alarm first being

issued. This, however, depends on the system configuration.

If the battery voltage subsequently drops further, backup of memory can

no longer be provided. Turning on the power to the control unit in this

state causes system alarm 910 (SRAM parity alarm) to be issued because

the contents of memory are lost. Replace the battery, clear the entire

memory, then reenter the data.

Replace the memory backup battery within a few minutes while the

control unit is brought off.

The following two kinds of batteries can be used.

D Lithium battery, incorporated into the CNC control unit.

D Two alkaline dry cells (size D) in an external battery case.

Complete steps (1) to (3) within 30 minutes.

If the battery is left removed for a long time, the memory

would lose the contents.

If there is a danger that the replacement cannot be

completed within 30 minutes, save the whole contents of the

CMOS memory to a memory card. The contents of the

memory can be easily restored with the memory card in

case the memory loses the contents.

Discard the dead battery, observing appropriate municipal rules and

regulations. When discarding the battery, insulate the terminal with a tape

so that no short-circuit would occur.

A lithium battery is used to back up BIOS data in the PANEL i. This

1.3

battery is factory-set in the PANEL i. This battery has sufficient capacity

BATTERY IN THE

to retain BIOS data for one year.

PANEL i (3 VDC)

When the battery voltage becomes low, the LCD screen blinks. (The LCD

screen also blinks if a fan alarm is issued.) If the screen blinks, replace

the battery as soon as possible (within one week). FANUC recommends

that the battery be replaced once per year regardless of whether a battery

alarm is issued.

Replacing the battery

(1) To guard against the possible loss or destruction of BIOS parameters,

write down the BIOS parameter values.

(2) Obtain a new lithium battery (A02B-0200-K102).

(3) After power has been supplied for at least five seconds, turn off the

power to PANEL i. Remove the intelligent terminal from the panel so

that replacement work can be done from the rear of the intelligent

terminal.

(4) Detach the connector of the lithium battery, and remove the battery

from the battery holder.

(5) Run the cable for the new lithium battery as shown in the Fig. 1.3.

(6) Attach the connector, and place the battery in the battery holder.

(7) Install PANEL i again.

(8) Turn on the power, and check that the BIOS parameters are maintained

(BIOS setup is not activated forcibly).

Between removing an old battery and inserting new battery, no more than

five minutes must be allowed to elapse.

One battery unit can maintain current position data for six absolute pulse

1.4

coders for a year.

BATTERY FOR

When the voltage of the battery becomes low, APC alarms 306 to 308 (+

SEPARATE

axis name) are displayed on the CRT display. When APC alarm 3n7 is

ABSOLUTE PULSE

displayed, replace the battery as soon as possible. In general, the battery

should be replaced within two or three weeks, however, this depends on

CODERS (6 VDC)

the number of pulse coders used.

If the voltage of the battery becomes any lower, the current positions for

the pulse coders can no longer be maintained. Turning on the power to

the control unit in this state causes APC alarm 300 (reference position

return request alarm) to occur. Return the tool to the reference position

after replacing the battery.

See Section 7.1.3 for details of connecting the battery to separate absolute

pulse coders. The battery for the built-in absolute pulse coder is installed

in the servo amplifier. For an explanation of the replacement procedure,

refer to the FANUC SERVO MOTOR a Series Maintenance Manual.

Replacing batteries

Obtain four commercially available alkaline batteries (size D).

(1) Turn on the power to the machine (i Series CNC).

(2) Loosen the screws on the battery case connected to the interface unit

of the detector separately installed, and remove the cover.

(3) Replace the dry batteries in the case.

Note the polarity of the batteries as shown in the figure below (orient

two batteries one way and the other two in the opposite direction).

WARNING

If the batteries are installed incorrectly, an explosion may

occur. Never use batteries other than the specified type

(Size D alkaline batteries).

CAUTION

Replace batteries while the power to the i Series CNC is on.

Note that, if batteries are replaced while no power is

supplied to the CNC, the recorded absolute position is lost.

1. METHOD OF REPLACING BATTERY

When the battery voltage falls, APC alarms 306 to 308 are displayed on

1.5

the screen. When APC alarm 307 is displayed, replace the battery as soon

BATTERY FOR

as possible. In general, the battery should be replaced within one or two

BUILT-IN ABSOLUTE

weeks of the alarm first appearing. This, however, depends on the number

PULSE CODERS

of pulse coders being used.

If the battery voltage drops any further, the current positions for the pulse

(DC6V)

coders will be lost. Turning on the power to the control unit in this state

results in APC alarm 300 (reference position return request alarm) being

issued. Return the tool to the reference position after replacing the battery.

So, FANUC recommends replacing the battery every year concerning

without the alarm occurring.

The battery for the built-in absolute pulse coder is connected with the

servo amplifier.

Note that the attachment methods of the battery and ordering

specifications of battery are different from SERVO AMPLIFIER a series

(SVM) to SERVO AMPLIFIER b series.

Replacement procedure

Replace the battery only while the power to the servo unit is on. If the

battery is replaced while the power is off, all of the absolute position

settings will be lost.

Replacement procedure is as follows.

1. Turn the servo unit (machine) on.

2. Place the machine in the emergency stop state.

3. Confirm that the servo motors are not active.

4. In case of SERVO AMPLIFIER a series, confirm that the LED that

indicates DC link charging status is not light.

5. Remove the battery and replace the battery.

6. The replacement is complete. Turn the servo unit (machine) off.

WARNING

D The power magnetic cabinet in which the servo units are

mounted has a high-voltage section. Don’t touch this

section that presents a severe risk of the electric shock.

D In case of SERVO AMPLIFIER a series, replace the battery

after confirm that the LED that indicates DC link charging

status is not light. Charged DC link has a high-voltage.

D Ensure that the replacement battery is of the correct type.

Otherwise, heat, explosion or ignition will occur. Always use

the specified battery.

D Pay careful attention to the polarity of the battery. Fault

polarity may be the cause of heat, explosion or ignition.

Also, it may be the cause of lost of the absolute position in

the pulse coder.

D Attach the socket to unused connector of CX5X or CX5Y.

These sockets that protect the connectors are attached to

these connectors in shipping from FANUC. If connector pins

of CX5X or CX5Y will short, heat, explosion or ignition will

occur. Also, it may be the cause of lost of the absolute

position in the pulse coder.
