2.1 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 is a compact Control Unit for single-axis applications and is snapped on 
to the SINAMICS S120 PM340 power module in blocksize format.
● SIMOTION D4x5 is a Control Unit for multi-axis applications in SINAMICS S120 booksize 
format and is offered in several performance variants:
– SIMOTION D425 (BASIC performance) for up to 16 axes
– SIMOTION D435 (STANDARD performance) for up to 32 axes
– SIMOTION D445/D445-1 (HIGH Performance) for up to 64 axes
Compared with SIMOTION D445, SIMOTION D445-1 offers an improvement in PLC 
and motion control performance of approximately 30%, depending on the application. 
Consequently, SIMOTION D445‑1 is the preferred solution for new applications as of 
V4.1 SP2.
This manual describes the SIMOTION D4x5 for multi-axis applications. Separate manuals are 
available for the SIMOTION D410 and D410-2 single-axis modules and the SIMOTION D4x5-2 
multi-axis 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.   
 
 
Note
In order to cover all versions of SIMOTION D for multi-axis applications, the product will be 
referred 
to as "D4x5". Specific product designations will be used for information that applies 
only to one product version, e.g. D435.
 
Application   
SIMOTION D4x5 is ideally suited to applications with many coordinated axes with high clock-
pulse rates.
Typical applications include:
