(Note-1): The Motion SFC program can also be started
automatically by parameter setting.
• Home position return data is not used, since home position return cannot be
performed in advanced synchronous control.
• JOG operation in advanced synchronous control is controlled using the JOG
operation data set by command generation parameters.
(1) Advanced synchronous control can be achieved using software instead of
controlling mechanically with gear, shaft, speed change gear or cam etc.
(2) The synchronous control parameter is required in addition to the positioning
parameter, servo program/Motion SFC program used in real mode.
(3) The procedure of positioning control in advanced synchronous control is shown
below:
1) Motion SFC program for advanced synchronous control 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 command generation axis in the advanced synchronous control is started.
3) Output the synchronous control parameter to the servo amplifier of each axis.
4) The servo motor is controlled.
