Setting of NCK PLC interface

Introduction
An automatic synchronization process during axis referencing must be disabled initially so as
to prevent any damage to grouping axes that are misaligned.
Disabling of automatic synchronization
The PLC user program sets the following for the axis data block of axis 1:
DB31, ... DBX29.4 = 0
DB31, ... DBX29.5 = 1
The NCK sets the following as a confirmation in the axis block of axis 1:
DB31, ... DBB101:
