The outstanding system features of the SINAMICS S120 Cabinet Modules provide the following advantages:

• Process optimization with minimal effort:
  • A standard PROFIBUS or PROFINET interface and various analog and digital interfaces enables easy integration into automation solutions.
  • Vector control ensures that they fulfill the most exacting requirements regarding the accuracy and dynamic response of drives.
• High level of reliability and availability:
  • Individual modules and power components can be replaced quickly and easily, which ensures a higher level of plant availability.
• Energy savings during operation:
  • The inverters on the motor side are coupled through a common DC link and allow energy to be exchanged between motors that are motoring and generating. In this way, energy is saved, the line infeed is relieved and line harmonics reduced.
  • Generally the line infeed is only dimensioned for the maximum energy required when motoring or the maximum current required when motoring – and not the sum of the energy requirements of the Motor Modules connected to the DC link. As a consequence, for example, for conveyor belts or motor test stands with Motor Modules that are simultaneously operated motoring and generating, a significantly smaller line infeed unit can be selected.
• Cost minimization during operation, maintenance, and service:
  • Simple commissioning thanks to the menu-driven STARTER commissioning tool.
  • Optional, menu-navigated AOP30 advanced operator panel with plain text display and bar-type display of process values.
  • All device modules are easily accessible, which makes them extremely service friendly.
• Space-saving design
• Environmentally-friendly operation:
  • The converters are exceptionally quiet and compact thanks to state-of-the-art IGBT power semiconductors and an innovative cooling concept.
