OUTLINE OF 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.
1.1
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 synchronous control" and starting synchronous control on each
output axis.

It is possible to control without amplifier
by setting the virtual servo amplifier.
*1 It is possible to drive the servo input axis except for the positioning control (home position return, manual control, speed-torque control,
synchronous control).
For details on the positioning control, the home position return, the manual control and the speed-torque control, refer to the following.

*2 Speed change gear can be arranged on one of "Main shaft side", "Auxiliary shaft side" or "After composite auxiliary shaft gear".
*3 For the drive method of the command generation axis, refer to the following.
