2.3.2 Positioning devices

Specifications of the positioning data, positioning devices and servo programs, etc.
used in the real mode differ in part in the virtual mode.
When using them in the virtual mode, refer to the "Q173CPU(N)/Q172CPU(N) Motion
controller (SV13/SV22) Programming Manual (REAL MODE)" after checking about a
different point in the real mode.
Positioning data used in the virtual mode are shown in Table 2.1 below.
