1. GENERAL DESCRIPTION
[Executing Positioning Control with a Servo System CPU]
Sequence program
Example: DSFRP instruction
Example: SVST instruction
1) In the sequence program, the servo program number and controlled
axis number are set with the DSFRP/SVST instruction.
2) When the DSFRP/SVST instruction is executed, the PCPU is
requested to execute the program with the designated servo
program number.

(1) Servo programs and positioning control parameters are set using a peripheral
device.
(2) Positioning is started by the sequence program (DSFRP/SVST instruction).
(a) The servo program number and controlled axis number are designated by
the DSFRP/SVST instruction.
1) The servo program number can be set either directly or indirectly.
2) The controlled axis number can only be set directly.
