 - 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) 

Assigning the following values in system variable #3004 allows the 
specification of whether feed hold and feedrate override are enabled in 
the following blocks or whether exact stop in G61 mode or by G09 
command is disabled.

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.

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.

  - 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

#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.
