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 followings for details on setting for the auxiliary shaft module.
