Servo programs serve to designate the type of the positioning control, and the
positioning data, required to execute positioning control with the servo system
CPU.
This section explains the configuration, and method for designating, servo
programs.
For details on the various types of servo program, see the explanation of
positioning control in Section 7.
This section describes the composition of servo programs and the area in which a
servo program is stored.
A servo program comprises a program number, servo instructions, and positioning
data.
When a program number and the required servo instructions are designated using
a peripheral device, the positioning data required to execute the designated servo
instructions can be set.
