1. OVERVIEW 
1.1 Overview 
This programming manual describes the dedicated instructions, positioning control 
parameters and positioning dedicated devices for mechanical system program 
comprised of a virtual main shaft or mechanical module required to execute the 
synchronous control in the Motion controller (SV22 virtual mode). 
The following positioning control is possible in the Motion controller (SV22 virtual 
mode).
