Sequence Programs
A sequence program is written in a text-based motion language.
There are two types of sequence programs.
Sequence Program Execution
A sequence program is executed by registering it in the M-EXECUTOR execution definitions.
The sequence programs are executed in ascending order.
The following figure shows an execution example.
If the execution type is set to an H-scan sequence program or L-scan sequence program, then the program
will be executed as soon as the definition is saved. If the execution type is set to a startup sequence pro-
gram, then the program will be executed the next time when the power supply is turned ON.

Main programs
SPM
(
=1 to
512)
Main programs are called from
the M-EXECUTOR program
execution definitions.
You can create up to 512 motion pro-
grams, including the following programs:
• Motion main programs
• Motion subprograms
• Sequence main programs
• Sequence subprograms
Subprograms
SPS
(
=1 to
512)
Subprograms are called from a
main program.
The same numbers are used to manage the sequence programs and motion 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
.
