Any name (variable name) can be given to common variables #500 to #519. It must be composed
of not more than 7 alphanumerics and it must begin with a letter. Do not use "#" in variable names.
It causes an alarm when the program is executed.

Variable names are separated by a comma (,).
Detailed description
(1) Once variable names have been set, they will not be cleared even when the power is switched
off.
(2) Variables in programs can be quoted by their variable names. In cases like this, the variables
should be enclosed in square parentheses.
(Example 1) G01X [#POINT1] ;
(3) The variable numbers, data and variable names appear on the screen of the setting and
display unit.
(Example 2)
Program ...... SETVN500 [A234567, DIST, TOOL25] ;
(Note) At the head of the variable name, do not use the characters determined by the NC for
use in arithmetic commands, etc. (e.g. SIN, COS).
Workpiece coordinate shift amount
The workpiece coordinate system shift amount can be read using variables #2501 and #2601.
By substituting a value in these variables, the workpiece coordinate system shift amount can be
