Motion Programs

A motion program is a program that is written in a text-based motion language.
There are two types of motion programs.
Main programs
Subprograms
Note: There are cases when the M-EXECUTOR cannot be used. Refer to the following section for details.

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).
• The No System Work Available Error is indicated by bit E in the Status Flags of the motion
program.
Motion Subprograms
Subprograms are created to perform common operations. They help minimizing the number of
program steps and allow efficient use of memory.
