Fundamentals of AC Drives - inclusive of Micro Master 440 (DR-DRV-FUN)

  • Fundamentals - Inclusive of Micro Master MM440


  • This course provides extensive information for activities in the field of electrical drive technology. The topics are addressed in a general manner, independently of specific products. In further courses on SINAMICS converters, you will be able to more easily realize details and understand their context. This is an advantage both in commissioning and diagnostics, and when configuring and planning drive systems. Practical exercises using a MICROMASTER 440 Training Case are an important component. On completion of the course, you will have mastered safe handling of the STARTER commissioning tool.
