(2) Common Variables (#100 to #299, #500 to #999)
Common variables means the variables that can be used in common in main programs, sub-
programs, microprograms, and those called up in nesting. Therefore, the common variable
where the result of an operation executed in a macroprogram is saved can be used in another
microprogram. For common variables, argument specification is not allowed.
FIGURE 4.4.3.1 Common Variables
• Common variables are classified into two types according to the state they are in when
the NC is reset.
Table 4.4.3.1 Common Variables
• The number of sets of the common variables can be optionally expanded.
#100 to #299
The content is <empty:> when the power is turned ON or the NC is reset.
By setting parameter “pm4009 D] = 1”, the content is not cleared to <empty>.
#500 to #999
The content is saved and not cleared to <empty> when the power is turned ON
or the NC is reset.
