SINAMICS S120 - Diagnostics at Chassis- and Cabinet Units (DR-S12-CHA)

  • You are responsible for reliable operation of the SINAMICS S120 drives with power ratings exceeding 100 kW. You already know the system from the booksize format with its modular structure. In this course you will learn how to handle chassis units and cabinet units. The focus is on understanding the converter design and the differences with respect to the booksize format.


  • After the course, you will be able to go about resolving faults in a targeted way. By means of circuit diagrams, you will be able to identify and determine interfaces and replace components. Using the AOP30, you will be able to back up data and recommission the drive system.
