1.1 GENERAL WARNINGS AND CAUTIONS
The following warnings and note describe precautions on handling
CNCs, which must be observed to ensure safety when using machines
equipped with a CNC.
WARNING
1 Before operating the machine, thoroughly check the
entered data. Operating the machine with incorrectly
specified data may result in the machine behaving
unexpectedly, possibly causing damage to the
workpiece and/or machine itself, or injury to the
user.
2 The parameters for the CNC and PMC are
factory-set. Usually, there is no need to change
them. When, however, there is no alternative other
than to change a parameter, ensure that you fully
Failure to set a parameter correctly may result in the
machine behaving unexpectedly, possibly causing
damage to the workpiece and/or machine itself, or
injury to the user.
NOTE
Command programs, parameters, and variables are
stored in nonvolatile memory in the CNC. Generally,
the contents of memory are not lost by a power
on/off operation. However, the contents of memory
may be erased by mistake, or important data in
nonvolatile memory may have to be erased upon
recovering from a failure.
To enable the restoration of data as soon as
possible if such a situation arises, always make a
backup of the data in advance.
