4.1.1 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 Section 4.1.2 and Section 4.1.3 for details on setting for the main shaft module.
