The TNC data and the PLC data are located on the hard disk of the iTNC 530 as well as the
complete NC software, including the setup files.
Note:
With dual-processor controls, the Windows system is located on the hard disk.
Caution
If there are defects on the hard disk, it may be possible that no functions at all can be called.
The MC 422 includes the so-called drive assembly. It is permanently installed.
The MC 422 B and the MC 420 have an expansion case for the HDR (Hard Disk Removeable).
Depending on the operating conditions (e.g., vibration load, dirt), the hard disk is exposed to
higher or lower loads. HEIDENHAIN thus recommends to have the hard disk checked after
3 to 5 years.
Caution
As the complete NC software is located on the hard disk it is object of the export
limitations.
