Smart Drive Assumes Local Control


Frequency inverters can react flexibly in case of disrupted communication with a central control system.


The on-board, pre-programmed PLC can take control, initiate a defined state for halting operations, or keep the application running. In process plants this can help avoid costs, for instance by preventing spoiled batches. In manufacturing facilities, material flow can be maintained. As these intelligent drives feature various interfaces and are able to evaluate sensor and actuator data, optimal integration in the application is ensured.


Additional uses beyond fallback scenarios include:

  • switching the smart drive over to local control
  • distributed frequency converter can also be equipped with switches for manual drive direction and speed control
  • integrated PLC functions are programmed using IEC 61131-3 Structured Text or Instruction List text-based languages
