- Alarm #3000 (Attribute: W)

When an error is detected in a macro, an unit can enter the alarm state.
In addition, an alarm message of up to 60 characters with alphabet and
numerals can be specified between a control-out and a control-in after
the expression. When an alarm message is not specified, a macro
alarm is used instead.

When bit 1 (MCA) of parameter No.6008 = 0

#3000 = n (ALARM MESSAGE); (n: 0-200)

On the screen, the alarm number obtained by adding the value of
#3000 to 3000 and alarm message appear.

(Example)

#3000 = 1 (ALARM MESSAGE);

→

"3001 ALARM MESSAGE" appears on the alarm

screen.

When bit 1 (MCA) of parameter No.6008 = 1

#3000 = n (ALARM MESSAGE); (n: 0-4095)

On the screen, the alarm number of #3000 and alarm message
appear after MC.

(Example)

#3000=1 (ALARM MESSAGE);

→

"MC0001 ALARM MESSAGE" appears on the alarm

screen.

- Clock #3001, #3002 (Attribute: R/W)

The clock time can be obtained by reading system variables #3001
and #3002 for clocks. The time can be preset by entering a value in
the system variables.

- Controlling of single block stop and waiting for the auxiliary function completion

signal #3003 (Attribute: R/W)

Assigning the following values in system variable #3003 allows the
specification of whether single block stop is disabled in the following
blocks or whether a wait for the completion signal (FIN) of the
auxiliary function (M, S, T, or B) before going to the next block is
enabled. When a wait for completion signal is disabled, the
distribution end signal (DEN) is not sent. Be careful not to specify
the next auxiliary function without waiting for the completion signal.

- Enabling of feed hold, feedrate override, and exact stop check #3004

(Attribute: R/W)

NOTE

1 These system variables are provided to maintain

compatibility with conventional NC programs. It is
recommended that functions provided by G63, G09,
G61, and other G codes be used to enable or
disable feed hold, feedrate override, and exact stop.

2 When the feed hold button is pressed during

execution of a block for which feed hold is disabled:

<1> If the feed hold button is kept pressed,

operation stops after execution of the block.
When single block stop is disabled, however,
operation does not stop.

<2> If the pressed feed hold button is released, the

feed hold lamp lights, but operation does not
stop until the end of the first block that was
enabled.

3 #3004 is cleared by a reset.
4 If exact stop is disabled by #3004, the original exact

stop position between cutting feed and positioning
block is not affected. #3004 can temporarily
disable exact stop in G61 mode or by the G09
command between cutting feed and cutting feed.

- Stop with a message #3006 (Attribute: W)

When "#3006=1 (MESSAGE);" is commanded in the macro, the
program executes blocks up to the immediately previous one and then
stops. When a message of up to 60 characters with alphabet and
numerals, which is enclosed by a control-in character and control-out
character, is programmed in the same block, the message is displayed
on the external operator message screen.

be obtained for each axis by reading #3007.

Variable number

Variable name

Description

#3007

[#_MRIMG]

Status of a mirror image

When the status is indicated in binary, each bit corresponds with an
axis as follows.

Bit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16

For the 32 bits, 0 indicates that a mirror image is disabled and 1
indicates that a mirror image is enabled.

[Example] When #3007 is 3, a mirror image is enabled for the 1st and 2nd

axes.

NOTE

1 The status of a programmable mirror image is not

reflected on this variable.

2 When the mirror image function is set for the same

axis by the mirror image signal and setting, the
signal value and setting value are ORed and then
output.

3 When mirror image signals for axes other than the

controlled axes are turned on, they are not read
into system variable #3007.

- Status during restart of a program #3008 (Attribute: R)

Whether a program is restarting can be determined by reading #3008.

Variable number

#3008

[#_PRSTR]

0: Program is not restarting.
1: Program is restarting.

- Time #3011, #3012 (Attribute: R)

Year/month/date and hour/minute/second can be obtained by reading
system variables #3011 and #3012. This variable is read-only. To
change year/month/date and hour/minute/second, use the timer screen.

[Example] May 20, 2004, PM 04:17:05

#3011 = 20040520

#3012 = 161705

- Total number of parts and the number of required parts #3901 and #3902

(Attribute: R/W)

The number of required parts and the number of machined parts can
be displayed on the screen by using the operation time and part
number displaying function. When the (total) number of machined
parts reaches the number of required parts, a signal indicating the fact
is sent to the machine (PMC side).
The system variables can be used to read or write the total number of
parts and the number of required parts.
