9.1.4 Memory card functions
This chapter describes the basic functions of the memory card in the SINAMICS DCM
system.
Basic information
The CUD (Control Unit for the SINAMICS DCM) manages three memory areas:
● A volatile memory, the RAM, also called work memory
● A non-volatile memory, the ROM, also called flash memory
● An optionally available portable memory card
Note
Memory cards can be ordered as an option (S01/S02) or as accessories, see Chapter
Ordering information for options and accessories (Page 30).
SINAMICS DCM does not accept other memory cards.
The work memory receives all project information and application programs while the device
is being operated. To save the current data from the work memory, you must copy it to non-
volatile memory before shutting down, see Chapter "Commissioning", "Copy RAM to ROM"
function.
An optional memory card is used:
● For saving various parameter data sets
● For transferring the parameter data sets to additional SINAMICS DCM drives
● For series commissioning
The memory card is needed:
● For installing software updates
● For using an AOP30 in languages other than German, English and Chinese
● To use the function "SINAMICS Link" (see Chapter "Communication via SINAMICS Link")
● To load the DCC block library into the drive
