(Note) : Motion SFC program can also be started automatically
by parameter setting.
• Home position return data is not used, since home position return cannot be executed in virtual mode.
(Home position return is executed in real mode.)
• JOG operation in virtual mode is controlled using the JOG operation data set by drive module parameters.
(1) Synchronous control with software is performed using the mechanical
system program comprised by virtual main shaft and mechanical module in
(SV22) virtual mode.
(2) Mechanical system programs is required in addition to the positioning
parameter, servo program/Motion SFC program used in real mode.
(3) The procedure of positioning control in virtual mode is shown below:
1) Motion SFC program for virtual mode is requested to start using the
D(P). SFCS instruction of the sequence program.
(Motion SFC program can also be started automatically by parameter
setting.)
2) The virtual servomotor of the mechanical system program is started.
3) Output the operation result obtained through the transmission module to
the servo amplifier set as the output module.
4) The servomotor is controlled.
