(2) Common Variables (#1 00 through 49, #500
through #559)
A common variable may be shared by macros
and through all macros of all nesting levels. That
is, the common variable enables a macro to refer
to the results obtained by another macro.

Common variables are divided into the following
two types depending on clear conditions:
A . #100 through #149: These common variables
are cleared at the time of power-on and reset
operations and are set to They are not
cleared by reset operation in some controls if
parameter #6008 D 1 is set to “ 1.”
B. #500 through 559 These common variables
are not cleared at the time of power-on and reset
operations.
The common variables are available to the
user without restrictions. They cannot be
designated by arguments. Indirectly, however,
they can be designated as follows:

A system variable is the one whose use is unique
to the system.
There are following types of sys -
tem variables :
A. Interface input signals . . . through
B. Interface output signals . . . through
#1115,
D. Alarm message display . . .
E. . . . #3001, #3002
F. Single-block stop and auxiliary-function
completion wait control . . . #3003
G. Feed-hold, feedrate-override, and
stop control . . . #3004
H. R S 2 3 2 C data output . . . #3100 (print out
feature) .
I . Modal information . . . #4001 through #4120
J. Position information . . . through
Note: The interface input and output signals of
(A) and (B) may not be installed. Follow the
specifications of the machine builder.
The following paragraphs describe the de-
tails of the variables mentioned above.

a, When one of system variables #1000 through
#1015 is specified to the right-hand of an opera-
tional expression, on state of each of
user-macro-dedicated 16-point input signals is
read.
The relationships between the input signals
and the system variables are as shown below.
