No user-specific SDB1000 exists. The default SDB1000 was loaded during startup. With- out process peripherals, the NC is ready for a start-up. The alarm is triggered the first time the NC is switched on or once if the SDB1000 stored in the supported RAM is lost.

Create the user-specific SDB1000 and load it on the control system, or select and activate it via MD 11240 standard SDB1000. Restart the NC. If the error occurs the next time the NC is switched on, the SDB1000 which was loaded contains an error and must be created again.
Clear alarm with the Delete key or NC START.
