For restoring a SRAM Backup, following steps shall be performed:
• Prepare a memory card with the SRAM Backup files. Note: Contrary to FROM files, the
SRAM files must comply to the naming, which has been given by the CNC. The original file
name must not be changed. In case of a SRAM Backup two examples for file names are
given dependent on the SRAM size:
1 MegaByte SRAM size 3 MegaByte SRAM size
SRAM1_0A.FDB SRAM3_0A.FDB
SRAM1_0B.FDB SRAM3_0B.FDB
SRAM3_0C.FDB
SRAM3_0D.FDB
SRAM3_0E.FDB
SRAM3_0F.FDB

• Apply the memory card to the PCMCIA Slot of the Display Unit.
• Start the Boot Menu by pressing two most-right soft keys during power up of the CNC.
• From the Main Menu select [SRAM DATA BACKUP]
• In the Sub Menu select SRAM RESTORE to send SRAM data from memory card to SRAM
of the CNC. Navigate by using [UP] and [DOWN] soft keys.
• Press the [SELECT] key and the desired files are displayed.
• Confirm the selection by pressing [YES]
• Dependent on SRAM size, up to six files are loaded from memory card.
Please wait until the message RESTORE COMPLETE is displayed.
• Press [SELECT] key.
• With soft keys [UP] and [DOWN] select END item and press soft key [SELECT] to come
back to the main menu.
• In the Main Menu select another operation with [UP] and [DOWN] soft keys and press
[SELECT]
• Move to END item and press [SELECT] and [YES] for terminating Boot Menu. The CNC will
