• Standard System Functions
The following functions for communications and other purposes are provided as standard functions 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.

You can create up to 512 motion pro-
grams, including the following programs:
• Motion main programs
• Motion subprograms
• Sequence main programs
• Sequence subprograms

Subprograms are called from a
main program.
1. The same numbers are used to manage the motion programs and sequence programs. Use a unique
number for each program.
• Motion program numbers are given in the form MPM or MPS.
• Sequence program numbers are given in the form SPM or SPS.
2. The number of motion programs that can be executed simultaneously depends on the model of the
Machine Controller. If the number of simultaneously executable programs is exceeded, an alarm
will occur (No System Work Available Error).
