USB drives

USB drives enable you to exchange data. For example, you can copy to the NC and execute
programs that were created externally.
NOTICE
Interruption of operation
Direct execution and simulation from the USB flash drive is not recommended, because
machining can be undesirably interrupted, therefore resulting in workpiece damage.
Partitioned USB flash drive (TCU)
If the USB flash drive has several partitions, these are displayed in a tree structure as a subtree
(01,02,...).
For EXTCALL calls, enter the partition (e.g. USB:/02/... or //ACTTCU/FRONT/02/... or //ACTTCU/
FRONT,2/... or //TCU/TCU1/FRONT/02/...)
You can also configure any partition (e.g. //ACTTCU/FRONT,3).
Procedure
Note
The "USB" softkey can only be operated when a USB flash drive is inserted in the front interface
of the operator panel.
