2.3 Differences Between The REAL and VIRTUAL Modes
Portions of the positioning data, positioning device, and servo programs, etc., used
in REAL mode operations are different when used in VIRTUAL mode operations.
The Motion Controller (SV13/22 REAL Mode) Programming Manual (type A273UH
CPU/A173UHCPU(-S1)) should be read after acquainting yourself with these
differences.
