10.1 Mixed Function of Virtual Mode with Real Mode

Refer to Section 1.3.4 of the "Q173CPU(N)/Q172CPU(N) Motion controller
(SV13/SV22) Programming Manual (Motion SFC)" for the correspondence software
version.
When the output axis No. to execute positioning control directly is selected in the
mixed function of virtual mode with real mode, a positioning control of axis which is not
used in the mechanical system program can be executed simultaneously during the
mechanical system program.

Details
Positioning control for preset axis is
executed during synchronous
control/cam control in the
mechanical system program.
Cam axis operation is switched to
ball screw operation in the
mechanical system program.

Applications
It is used in the system for which
conveys while executing synchronous
control.
When an error occurs during cam axis
operation and it becomes outside the
stroke range, it can be returned within
the stroke range by switching from cam
to ball screw.
