6.21  Quantity structures 
With SIMOTION D, the SIMOTION PLC and motion control functionalities as well as the 
SINAMICS S120 drive software run on a shared control hardware. The IEC 61131-3-
compliant PLC integrated in SIMOTION D means that the system is not just capable of 
controlling sequences of motions, but the entire machine as well.  
●  The scaling of the PLC and motion control functionality is performed via control units of 
various performance classes for SIMOTION D 
–  SIMOTION D410-2 is predestined for single-axis solutions and small multi-axis 
solutions with typically 2-3 axes 
–  SIMOTION D425-2 (BASIC performance) for up to 16 axes 
–  SIMOTION D435-2 (STANDARD performance) for up to 32 axes 
–  SIMOTION D445-2 (HIGH performance) for up to 64 axes 
–  SIMOTION D455-2 DP/PN (ULTRA-HIGH performance) for up to 128 axes or 
applications with very short control cycle clocks 
The possible axis quantity structures depend on the required servo and interpolator cycle 
clocks and apply for electric, hydraulic and virtual axes.  
●  The scaling of the drive computing performance is performed via SINAMICS drive 
controls for the SIMOTION D4x5-2. With the SIMOTION D4x5-2, the drive control of a 
CU320-2 is already integrated (SINAMICS Integrated). These can be extended as 
follows: 
–  SINAMICS S110/S120 control units can be connected via PROFIBUS or PROFINET 
–  The CX32-2 controller extension can be connected via DRIVE-CLiQ 
SIZER 
With the SIZER configuration tool, you can easily configure the SINAMICS S120 drive family 
including SIMOTION. It provides you with support for selecting and dimensioning the 
components required for a Motion Control task.  
●  Dimensioning of the PLC and motion control functionality --> selection of the 
SIMOTION D control unit 
●  Dimensioning of the drive computing performance and the required drive components. 
Depending on your performance requirements, SIZER determines the possible number of 
axes and the resulting utilization on the SIMOTION and SINAMICS side.  
Drive quantity structure  
The following table can be used for a rough estimation of the maximum possible quantity 
structures on the drive side.  
Depending on the functionality used, more or less performance resources are used on the 
drive control.  
The performance points specified in the table can be used for a rough estimation. Maximum 
15.5 performance points are available for each drive control (SINAMICS Integrated, CX32-2, 
CU320-2).
