1 OVERVIEW
1.2.5 Positioning dedicated devices/special relays/special registers
(1) Positioning dedicated devices
The following section describes the positioning dedicated devices.
A range of up to 32 axes is valid in Q173CPU(N), and a range of up to 8 axes is
valid in Q172CPU(N).
Refer to the "Q173CPU(N)/Q172CPU(N) Motion controller (SV13/SV22)
Programming Manual (REAL MODE)", "Q173CPU(N)/Q172CPU(N) Motion
controller (SV22) Programming Manual (VIRTUAL MODE)" for details of the
positioning dedicated devices.
