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.
With many innovative functionsSafety 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 commissioningusing the SIZER and STARTER tools and data backup using the Basic Operator Panel (BOP-2) and MMC/SD card
Efficient and consistent solutionsvia Totally Integrated Automation (TIA), consistency from SINAMICS through to the automation level
