Cautions

This manual describes some optional functions, too, but some of these may not be available
in your machine. To determine the optional functions installed in your machine, refer to the
specification documents or manuals published by the machine tool builders.
We have made every effort to describe individual functions and their relationships to other
functions as accurately as possible. However, there are many things that cannot or must not
be performed and it is not possible to describe all of these. Accordingly, readers are
requested to understand that unless it is specifically stated that something can be performed,
it should be assumed that it could not be performed.
Also bear in mind that the performance and functions of an NC machine tool are not
determined solely by the CNC unit. The entire control system consists of the mechanical
system, the machine operation panel and other machine related equipment in addition to the
CNC. Therefore, read the manuals published by the machine tool builder for detailed
information relating to the machine.
