6.4 Configuring a CX32-2
6.4.1 Overview
The SIMOTION CX32-2 controller extension is a component in SINAMICS S120 booksize
format and enables scaling of the drive-side computing performance of the
SIMOTION D4x5-2 control units. Each CX32-2 can operate up to six additional servo, six
vector or twelve
V
/
f
drives.
The CX32-2 controller extension offers the following advantages:
● With a width of only 25 mm, the CX32-2 is extremely compact.
● The CX32-2 is connected to the SIMOTION D4x5-2 via DRIVE-CLiQ, so that high-
performance, isochronous closed-loop control of the drives is possible without the need
for additional modules.
● The communication interfaces on the SIMOTION D4x5-2 remain available for other
connections.
● The data for the CX32-2 is stored exclusively on the SIMOTION D4x5-2 CompactFlash
card, which means that no action needs to be taken when the module is replaced.
● The "Control operation" signal from an infeed connected to the SIMOTION D4x5-2 is
particularly easy to interconnect to the drives of a CX32-2.
● SIMOTION CX32-2 is automatically also upgraded when the SIMOTION D4x5-2 is
upgraded
6.4.2 Basic principles of the CX32-2
Basic principles of the CX32-2
Each CX32-2 is entered as a separate DRIVE object in the project navigator on the level of
SINAMICS Integrated. In principle, a CX32-2 can be configured the same way as SINAMICS
Integrated.
Communication
With CX32-2 (as with the SINAMICS Integrated), communication takes place via the
PROFIBUS Integrated, but is still routed by the SINAMICS Integrated to the relevant CX32-2
via DRIVE-CLiQ.
Communication with the CX32-2 runs in the same cycle (same DP cycle ) as communication
with the SINAMICS Integrated. Direct communication between two CX32-2 modules or the
SINAMICS Integrated and CX32-2 is not possible. Exception: Interconnection of the
"Operation" signal of the infeed for the CX32-2. For a description of how to interconnect to
the "Operation" signal, refer to Section Interconnecting the infeed "Operation" si
gnal on the
CX32-2 (Page 204).
