List of synchronous control modules
The modules used in the synchronous control are as follows.
• Input axis module can be set to one of servo input axis, command generation axis, or synchronous encoder
axis.
• Speed change gear can be arranged on one of main shaft side, auxiliary shaft side or after composite
auxiliary shaft gear.
• Set the movement amount of input axis module as large as possible to prevent the speed fluctuation of
output axis module in the synchronous control. If the movement amount of input axis module is small, the
speed fluctuation of output axis module may occur depending on the setting for advanced synchronous
parameter.
• The following items can be monitored in the "Synchronous Control Image" window using the Simple Motion
Module Setting Function; each synchronous control monitor data and the rotation direction of main shaft
main input axis, main shaft sub input axis, auxiliary shaft axis, and output axis (cam axis command position
value).
