2.1.1

Erasing the S-RAM area of the NCK (as from SW 6)

General notes In order to obtain a defined initial state when installing/upgrading the control you
must erase the S–RAM of the NCK–CPU. In this way you will avoid errors caused
by incorrectly initialized data.
Explanation The S–RAM of the NCK–CPU contains data that must be stored permanently in
the control, even after it has been switched off. These are user data (machine
data, R parameters, tool data ...) and internal data.
Pressing the softkey "Format user data" on starting up the control only initializes
the user data, the other r areas remain partially undefined which can result in spo-
radic errors.
In SW 6 and higher, the S–RAM of the NCK–CPU is automatically deleted when
you update the software or when the CSB battery fails, thus providing a defined
initial state.
On initial start–up of the control after the software has been updated, alarm 10
"Start–up after software update" is displayed and the control powers up in start–
up mode. You must then perform a start–up of the control.
