OUTLINE OF ADVANCED SYNCHRONOUS
CONTROL
The outline, specifications, and operation method of synchronous control using the 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.
The available functions are limited depending on the versions of the software of the Motion module and 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, command generation axis, or
synchronous encoder axis) by setting the "parameters for advanced synchronous control" and starting synchronous control on
each output axis.
