The machine data for the memory configuration takes effect at Power-On.
!
Caution
Before increasing the size of DRAM areas (e.g. local user variables or function
parameters), first check whether the available memory is sufficient (MD 18050
must be greater than 15000). If more dynamic memory is required than is
available, then at the next power-up, the SRAM will be deleted as well without
warning and the following user data will be lost:
– Drive machine data
– Part programs
– Memory configuration data
– Configurable memory areas

memory configuration,
Section: Determining the memory required.
The HMI user interface can be used to display the system resources currently in
use in the NCK and HMI areas. They can also be edited if the user has the ne-
cessary access rights.
Procedure:
Press the “Start-up” soft key on the HMI user interface.
The “NC memory” soft key also appears when the Extended key is pressed.
When the soft key is pressed, an overview of the current RAM allocation is
displayed:
S Static RAM (SRAM)
S Dynamic RAM (DRAM)
To view the memory for configured machine data in greater detail, further areas
can be displayed by pressing the “SRAM” or “DRAM” soft keys.
