The Program Parameters NCK areas are used to enter program parameters
and setting data. The entered values are stored directly in the NCK memory.
This memory area is battery-backed, i.e. the data are retained even when the
control is switched off.
Fig. 5-2 Basic display area: Program Parameters
The program parameters and setting data are referenced by the control during
execution of a part program and throughout operation of the machine. In
contrast, all of the workpiece files in the Programming/ Data Management
areas are stored on the hard disk. Their values therefore have no immediate
effect on machine operation.
The program parameters and setting data assigned to a workpiece are loaded
from the hard disk to the NCK memory and are active only when the workpiece
has been loaded.
The computer link in the NCK area is optional and is therefore described in
separate publications.
