6.2 General machine data (general data)
The number of areas is specified in NC MD 210. The number of TO areas is limited to
between 1 and 4. One TO area is provided when a value of 0 is entered. If the specified value
exceeds 4, it is set to 4 internally and alarm 47 triggered.
The limits of the TO areas are defined by specifying the TO start numbers in NC MD 211 to
214. The last TO area extends from the last value specified in NC MD 211 - 214 to the
maximum tool offset number (observe NC MD 13 and 104x).
Caution!
A modification does not become effective until user memory is formatted. In "Overall Reset"
mode, user memory is formatted with the "Format User Data" or "Format TO Data" softkey.
For detailed information on invoking the "Overall Reset" mode, refer to Section General Reset.
