For SIMOTION D435 with MLFB 6AU1 435-0AA00-0AA0, a fan battery module is required at 
ambient temperatures greater than or equal to 43 °C. 
 
Hardware components: SIMOTION runtime module and SINAMICS drive module 
As the central hardware, SIMOTION D uses the SIMOTION D4x5 as a control unit consisting 
of the SIMOTION runtime module and the SINAMICS firmware. The control unit uses the 
SINAMICS Integrated drive with various SINAMICS S120 drive modules (Line and Motor 
Modules) to perform open-loop and closed-loop control of the axis grouping. A range of 
additional SINAMICS S120 components, such as SMC encoder systems or terminal 
modules can be connected via DRIVE-CLiQ. Moreover, the functionality can be expanded 
with the distributed I/O via PROFIBUS or with the CBE30 Option Module via PROFINET IO.  
The following figure shows a typical SIMOTION D axis grouping.
