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.
