SINAMICS G120 Built-in units

The modular inverter - space-saving, safe and rugged

SINAMICS G120 – Description

SINAMICS G120, FSB, CU240B-2 with PM240 and BOP-2

SINAMICS G120 is a modular drive inverter system that comprises various function units. These are essentially:

  • Control Unit (CU)

  • Power Module (PM)

The CU controls and monitors the PM and the connected motor in several operating modes that can be selected. It supports communications to a local control as well as to monitoring devices and equipment. The PMs has a power range from 0.37 kW to 250 kW.

SINAMICS G120 – a brief Summary of its Strengths

  • With many innovative functions
    Safety Integrated for safety-relevant machines and systems, capable of regenerative feedback into the line supply for energy saving and a new cooling concept

  • Faster engineering, fast commissioning
    using the SIZER and STARTER tools and data backup using the Basic Operator Panel (BOP-2) and MMC/SD card

  • Efficient and consistent solutions
    via Totally Integrated Automation (TIA), consistency from SINAMICS through to the automation level
