• CF_CARD: for CompactFlash Card
• USB: for USB front connection
CF_CARD: and LOCAL_DRIVE: can be alternatively used.
Note
Execute from external source via USB drive
If external programs are to be transferred from an external USB drive via a USB interface,
only the interface via X203 (with the name "TCU_1") can be used.
NOTICE
Execute from external source via USB FlashDrive (at the USB front connection)
Direct execution from a USB FlashDrive is not recommended.
There is no protection against contact problems, falling out, breakage through knocking or
unintentional removal of the USB FlashDrive during operation.
Disconnecting it during operation will result in immediate stopping of the machining and,
thus, to the workpiece being damaged.
