Auxiliary Shaft Module

Overview of auxiliary shaft module

For the auxiliary shaft module, the input value is generated from the auxiliary shaft. The input value can be converted by the
auxiliary 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 auxiliary shaft module.
