14. SCREEN HARDCOPY

OPERATION

B-63534EN/02

SCREEN HARDCOPY

14

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

1

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

set bit 7 (HDC) 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.

2

Insert a memory card.

3

To start the function, set hardcopy start signal HDREQ <G067#7> to

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

4

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

copy stop signal HDABT <G067#6> to 1.

5

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.

6

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.

1126

B-63534EN/02

OPERATION

14. SCREEN HARDCOPY

NOTE

1

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.

2

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

instance, the screen hardcopy operation may disable the

[SHIFT] or [CAN] key.

3

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.

1

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

function)

2

System alarm screen

3

Screen while RS-232-C is being used

4

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

produced in a rest of the operation.)

Screen hardcopy function can not be used with the 160i/180i/160is/180is.

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

1

A screen hardcopy file produced after the file HDCPY099.

BMP is output will be named as HDCPY000.BMP.

2

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.

3

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.

NOTE

A lithium battery is installed as standard at the factory.

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

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.

If a battery voltage of 0 V is indicated, you need to make a zero point

return.

- The absolute pulse coder of the ai series servo motor is incorporated

with a backup capacitor as standard. This backup capacitor enables an

absolute position detection to be continued for about 10 minutes.

Therefore, no zero point return need be performed if the time during

which servo amplifier power is kept off for battery replacement is

within 10 minutes.

- When the replacing of the battery takes more than 10 minutes, replace

the battery after see Item [Caution No.1 for battery replacement].
