Part of a complete and seamless family of products, the frequency converter meets practically every requirement.

Unlock your drive’s digital potential and harness the power of the elements.

Specific functions for water / waste water applications

  • Deragging function to sustainably remove deposits and dirt from pump impellers.
  • The pipe filling mode allows pipes to be gently filled at the beginning of the control process before going into closed-loop controlled operation.
  • The innovative cavitation detection function protects pumps and reduces maintenance costs.
  • The keep running mode reduces the speed before a possible shutdown.
  • Multipump operation (staging) allows several pumps to be controlled from just one frequency converter.
  • Many additional functions, directly supported by the converter, makes SINAMICS G120X universally applicable in infrastructure projects.

Specific functions for HVAC applications

  • The flying restart function reduces starting times after brief power failures.
  • SINAMICS G120X also provides an automatic restart function after power failures.
  • The essential service mode maintains fan operation for smoke extraction systems or emergency ventilation systems for as long as required in extreme situations.
  • Multipump operation (staging) allows for the control of several pumps with just one frequency converter.
  • Skipping critical motor speeds is another HVAC-specific feature which reduces vibration and, in turn, premature wear.
  • SINAMICS G120X also provides a real-time clock for autonomous, time-controlled operation as well as a timestamp for fault and alarm reports


With SINAMICS G120X, the new low cost frequency converter comes as a complete product series – standardized and seamless when it comes to all supply voltages and supply types and is available in a power range extending from 0.75 kW to 630 kW.
