Properties of the CF card 
The CF card is mandatory for operation of the SIMOTION D4x5. The CF card is not supplied 
with the SIMOTION D4x5 and must be ordered separately.  
The SIMOTION Kernel and the software used to control the drives (SINAMICS firmware) are 
contained on the CF card. 
The CF card is used for: 
•  Updates (e.g., SIMOTION firmware update) 
•  Backing up the technology packages and user data (programs, configuration data, 
parameter assignments) 
The licenses for the technology objects are linked to the serial number of the CF card. This 
means the CF card can be inserted in a different SIMOTION D4x5 without having to change 
the licenses.  
The CF card is supplied in a bootable format with the latest SIMOTION Kernel and drive 
software. 
 
 
Caution 
The CF card may only be inserted or removed when the control unit is disconnected from the 
power supply. 
 
Additional information 
For additional information about inserting, changing, write-accessing, and formatting the 
CF card, refer to the 
SIMOTION D4x5
 Commissioning Manual. 
2.2.3  RESET button 
Arrangement 
The RESET button is located behind the blanking plate on the SIMOTION D4x5.  
Performing a reset operation 
A reset causes the entire system to be reset and requires the system to be ramped-up again. 
It is similar to a "Power On Reset" except that the 24 V power supply does not have to be 
switched off.
