Hardware configuration
You can expand the drive configuration limits of a SIMATIC Drive Controller, for example with
SINAMICS S120 Control Units (CU320-2) or SINAMICS S210 (for example for individual
drives). Additional SINAMICS drive systems must be connected over PROFINET if they are
operated isochronously with the servo clock with SINAMICS Integrated.
Computing performance at the drive cannot be increased with a SIMOTION CX32-2
Controller Extension as with SIMOTION D4x5-2.
Note
The PROFIBUS interface cannot be connected to other clock systems. If you expand the drive
configuration limits with distributed drive systems, those systems must be connected over
the PROFINET IO interface X150. Only PROFINET interface X150 can be connected to the clock
system of SINAMICS Integrated and the X142 technology I/Os.
