5 SERVO PROGRAMS FOR POSITIONING CONTROL

5. SERVO PROGRAMS FOR POSITIONING CONTROL

Servo programs specify the type of the positioning data required to execute the
positioning control in the Multiple CPU system.
This chapter describes the configuration and setting method of the servo programs.
Refer to Chapter "6 POSITIONING CONTROL" for details of the servo program.

5.1 Servo Program Composition Area

This section is described the composition of servo programs and the area in which
stores the servo program.

5.1.1 Servo program composition

A servo program is composed a program No., servo instructions and positioning data.
When a program No. and the required servo instructions are specified using a
peripheral device, the positioning data required to execute the specified servo
instructions can be set.
