Siemens Answers with SINAMICS S120 Cabinet Modules: High Performance Enclosed Drive Line-ups

SINAMICS S120 Cabinet Modules

The concept of SINAMICS S120 enclosed drive cabinet modules is innovative: configure even the most complex multi-motor common DC bus drive line-ups or highest HP multiparallel drives up to over 5,000 HP by combining standard enclosed drive modules.

Now Meeting NEMA Standards

SINAMICS S120 Cabinet Modules are available in designs both to IEC standards (see Catalog D21.3)  or to NEMA standards with optional UL listing and SCCR up to 100 kA (see Catalog D21.7).

  • Line Connection modules (circuit breaker and accessories)

  • Line Infeed modules

    - Basic Line module - non-regenerative rectifier

    - Smart Line module - fully regenerative

    - Active Line module + Active Interface Module - fully regenerative, 
      clean power, power factor control

  • Motor modules - chassis format - approx. 100 to 6,000 HP (75 to 4,500 kW)

  • Motor modules - booksize format - from < 1.5 to approx. 125 HP ( < 1 to approx. 100 kW)

  • Central Braking modules

  • Motor-side filter/reactor cabinets

  • Cabinets for auxiliary power supplies

  • Cabinets for custom-designed control or other auxiliary equipment

  • Safety-Integrated technology

  • Flexible control topology due to DRIVE-CLiQ – the flexible backplane bus

  • Powerful high bus communications options including PROFIBUS, PROFINET, and EtherNet/IP

EtherNet IP Connectivity

Communicate without limits

Siemens brings the established power and flexibility of SINAMICS S120CM to your EtherNet/IP network, with direct connectivity to PROFIBUS, PROFINET, EtherNet/IP™ and standard Ethernet.

Customer Benefits

  • Custom drive systems with minimum engineering effort

  • Type tested standard modules offer high operational reliability and short lead times

  • Standardized interfaces simple plant design and operation

  • Flexibility to match requirements by a vast array of pre-designed standard options

  • Very compact design – optimized footprint

  • Flexible control topology by the combination of DRIVE-CLiQ – the flexible backplane bus – which allows remote mounting of control units, with powerful firmware that enables control of multiple drives in one control unit

Power ratings of drives that are accommodated in cabinet modules range from fractional to approx. 6,000 HP.

Technical Information

Voltage  and Power Ranges

3-ph. 380 - 480V AC: 2 - 4,000 HP (1.6 - 3,000 kW)

3-ph. 500 - 690V AC: 100 - 6,000 HP (75 - 4,500 kW)

Safety Integrated Technology

Safety is a primary issue in applications employing high performance drives.

Typical Applications

SINAMICS S120 cabinet modules are particularly suitable for drive tasks where several motors work together or very high HP ratings are required. Typical examples of this are:
