OUTLINE OF ADVANCED SYNCHRONOUS
CONTROL
The outline, specifications and the operation method of synchronous control using the Simple Motion module are explained in
this chapter.
This chapter helps to understand what can be done using the positioning system and which procedure to use for a specific
purpose.
There are restrictions in the function that can be used by the software of the Simple Motion module and the version of
engineering tool. For details, refer to "Restrictions by the version" in the following manual.

Outline of Synchronous Control

"Synchronous control" can be achieved using software instead of controlling mechanically with gear, shaft, speed change
gear or cam, etc.
"Synchronous control" synchronizes movement with the input axis (servo input axis or synchronous encoder axis), by setting
"the advanced synchronous control parameters" and starting synchronous control on each output axis.
