Setting of NCK PLC interface

Introduction
An automatic synchronization process during axis referencing must first be disabled in order
to prevent any damage to grouping axes that are misaligned.
Disabling of automatic synchronization
The PLC user program sets the following IS:
● For the leading axis (axis 1):
● For the synchronized axis (axis 3):
