ADVANCED SYNCHRONOUS CONTROL
The parameters and monitor data for synchronous control such as "Main shaft module", "Speed change gear module", and
"Output axis module" are explained in this chapter.
Configure the required settings according to the control and application requirements for each module.

Main Shaft Module

Overview of main shaft module

For the main shaft module, the input value is generated as a composite value from two input axes (the main and sub input
axis) through the composite main shaft gear. The composite input value can be converted by the main shaft gear that provides
the deceleration ratio and the rotation direction for the machine system, etc.
Refer to the following for details on setting for the main shaft module.
