NCK Reset
Via the "NCK reset" button, an NCK POWER ON reset is triggered.
On a NCK POWER ON reset, all active machining operations are stopped.
Drives that are in motion are not decelerated on their acceleration ramp but
at that their current limit.
After start–up, the NCK is in the reset state. Machine and user data are not
changed.
S
NCK Default Data
Via the "NCK reset" button, an NCK POWER ON reset is triggered followed
by NCK general reset. All active machining operations are stopped as de-
scribed under "NCK Reset".
After start–up, the NCK is in the reset state. All machine and user data are
deleted and standard machine data are loaded.
Notice
After "NCK Default Data" has been triggered, the NCK must be commissioned
again or a series startup file read in (see Section 15, Page 15-459).
S
Acknowledge alarm 4065
Via button "Acknowledge alarm 4065":

Interrupt: "4065 Battery–backed memory has been restored from

To acknowledge the alarm via softkey, it is first necessary to switch to the
follow–up softkey bar with the "ETC" key.
Note
Alarm 4065 is also acknowledged by NCK–POWER ON reset via "NCK Default
Data". Then the NCK must be commissioned again or a series startup file read
in (see Section 15, Page 15-459).
