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)".
The functionality in SINAMICS DCM is not guaranteed for memory cards from other
manufacturers!
SINAMICS DCM does not evaluate the position of the write protection slide switch.
Before removing the memory card from the slot, it is recommended that the "Safely
remove memory card" function is selected using p9400 = 2. Wait for p9400 = 3 ("Card
can be safely removed"). P9400 is set = 0 after the memory card has been removed
("No memory card inserted").
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 firmware 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
