 Functions
Functions are executed when they are called from a parent, child, or grandchild drawing with
the FUNC instruction.
Functions can be freely called from any drawing. The same function can be called simultane-
ously from different types of drawings or different levels of drawings. You can also call functions
from other functions that you have created.
The use of functions provides the following merits:
• Easy user program modularization
• Easy user program creation and maintenance
You can use standard functions that are provided by the system, and you can define user func-
tions.
• Standard System Functions
The following functions for communications and other purposes are provided as standard func-
tions in the system. You cannot change the system functions.
• User Functions
You can freely program the body of a user function and program the user function definitions.
A maximum of 2,000 user function drawings can be defined.
 Motion Programs
A motion program is a program that is written in a text-based motion language.
There are two types of motion programs.
