1.2 BACKING UP VARIOUS DATA ITEMS
With the CNC, various data items such as machining programs, offset
data, and system parameters are stored in the SRAM of the control
unit and are protected by a backup battery. However, an accident
can erase the data. By storing the data at another location (outside
the CNC), the data, when lost, can be restored.
So, when the machine is started up or data is updated, for example, the
data should be backed up (stored outside the CNC).
- Data backup operation
The data items listed below should be backed up. For the method of
data output operation, see the chapter of "DATA INPUT/OUTPUT" in
this manual.
<1> System parameters
→ See III-8.1.2.
<2> Machining programs
→ See III-8.1.1.
<3> Tool offset data
→ See III-8.1.3.
<4> PMC data
→ See PMC PROGRAMMING MANUAL (B-63983EN).
<5> Pitch error compensation data (when the pitch error
compensation function is selected.)
→ See III-8.1.4.
<6> Three-dimensional error compensation (when the
three-dimensional error compensation function is selected.)
→ See III-8.1.5.
<7> Custom macro variables (when the custom macro function is
selected.)
→ See III-8.1.6.
<8> Workpiece coordinate system setting data (when the workpiece
coordinate system function is selected.)
→ See III-8.1.7.
<9> Tool management data (when the tool management function is
selected.)
→ See III-8.1.9.
It is recommended that recording media (such as floppy disks and
memory cards) daily used with the machine be used to store data.
Stored data should be managed properly so that the data can be
restored quickly if a problem occurs.
