1.1  System overview 
Overview 
SIMOTION D is a drive-based version of SIMOTION based on the SINAMICS S120 drive 
family.   
With SIMOTION D, the SIMOTION PLC and motion control functionalities as well as the 
SINAMICS S120 drive software run on shared control hardware. 
SIMOTION D is available in two versions: 
●  SIMOTION D410-2 is a compact control unit predestined for single-axis applications. The 
control unit is snapped directly on to the SINAMICS S120 PM340 power modules in 
blocksize format and has an integrated drive control for either one servo, one vector or 
one 
V/f
 axis. 
●  SIMOTION D4x5-2 is a control unit for multi-axis applications in the SINAMICS S120 
booksize format. The following performance versions are offered: 
–  SIMOTION D425-2 (BASIC performance) control unit for up to 16 axes 
–  SIMOTION D435-2 (STANDARD performance) control unit for up to 32 axes 
–  SIMOTION D445-2 (HIGH performance) control unit for up to 64 axes 
–  SIMOTION D455-2 (ULTRA-HIGH performance) control unit for up to 128 axes or 
applications with very short control cycles 
The SIMOTION D4x5 2 is described in this manual. Separate manuals are available for the 
SIMOTION D410-2 and the D4x5/D410 predecessor modules. 
Like SINAMICS S120, SIMOTION D also follows the Totally Integrated Automation (TIA) 
concept. TIA is characterized by integrated data management, configuration, and 
communication for all products and systems. Thus, an extensive toolbox of automation 
modules is also available for SIMOTION D.
