SINAMICS S120 - Diagnostics and Service with STARTER (DR-S12-DG)

  • In this course you learn to determine the cause of faults and resolve them. You can also perform changes of the parameterization.


  • You are responsible for reliable operation of the SINAMICS S120 drive system. If faults occur, then these should be resolved in the shortest possible time and operation resumed.
  • In this course, you will learn how to correctly and safely handle SINAMICS S120 drives when a fault occurs. Based on various scenarios, you will practice suitable measures such as data backup, replacing components and recommissioning.
  • After the course, you can determine the cause of faults and resolve them faster. When changes are made to the plant or system, you are also in a position to adapt the parameterization.
