6.4  Controller Extension CX32 
6.4.1  Overview of CX32 
Properties   
The CX32 is a module in SINAMICS S120 booksize format. The CX32 allows scaling for the 
drive-end computing performance of the SIMOTION D435, D445 and D445-1 Control Units.  
Each CX32 can control up to 6 additional servo axes, 4 vector axes or 8 
V
/
f
 axes.  
The controller extension has 4 DI, 4 DI/DO and 4 DRIVE-CLiQ interfaces.   
Drive quantity structures  
If one or more CX32 modules are being used on a SIMOTION D435 or D445/D445-1, the 
number of drives that can be used on the SINAMICS Integrated is reduced by one. This 
gives the following quantified volumes: 
SIMOTION V4.1/V4.2 (SINAMICS V2.5/V2.6)
