Configuring a CX32-2

7.4.1

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
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

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" signal on the
CX32-2 (Page 221).
