SINAMICS S120 - Optimization for Fiber Industry (DR-S12-FI)


  • You already know the control structure of the drive system SINAMICS 120 and use the automatic optimization as well as the trace function. In this course you learn how you reach the highest dynamics and accuracy of the drive axis in fiber industry applications.
  • After the course visit you understand the interplay of mechanics, motor and drive converter. You can examine the system by means of frequency analysis and parameterize filters against unwanted vibrations correctly.
