• The 24 V electronics power supply is either provided from an external supply or from a Control Supply Module (CSM). The supply can also be taken from the central drive line-up using the 24 V terminal connector
• Use of Line Modules (Active Line Module, Basic Line Module and Smart Line Module) from the SINAMICS S120 product family
• The AM600 Adapter Module opens a line of distributed drive units. It feeds the DC link, auxiliary voltage, and DRIVE-CLiQ in a hybrid cable.
• If several drive units are to be operated, then the possible number depends on the central Control Unit. If an additional Control Unit is used, the closed-loop control signals are fed into the DRIVE-CLiQ line via a DRIVE-CLiQ Extension
• AM600 Adapter Module, DRIVE-CLiQ Extension and Hybrid Cabinet Bushing are not "visible" DRIVE-CLiQ nodes in the topology. The number of DRIVE-CLiQ Extensions is not restricted.
• As Control Unit or control, all multi-axis Control Units in the SINAMICS/SIMOTION/SINUMERIK range can generally be used (CU320‑2, D4xx‑2, CX32‑2, NCUxx). The releases of SINAMICS S120M for the corresponding systems are published via the Siemens Industry Online Support Portal: https://support.industry.siemens.com
