ACD-40 Data Sheet

The ACD-40 is a complete AC Drive training system featuring the Allen-Bradley PowerFlex 40 Variable Frequency Drive. This training system provides a hands-on study of a typical industrial AC variable frequency drive. This education system allows trainees to gain hands-on experience using an AC drive in an application-oriented setting. Our training system is accompanied by an instructor’s guide as well as a student manual. This manual is a comprehensive student resource, featuring thorough knowledge of the practical use of a motor control system.

This learning system includes practice exercises and testing, which enable tracking of learning progress. The curriculum begins with basic AC motor and drive fundamentals. It quickly moves on to programming the PowerFlex 40 using parameter flow charts and the included Human Interface Module with keypad and display. This comprehensive study finishes by outlining various troubleshooting techniques, focusing specifically on fault troubleshooting with drive system fault simulation to demonstrate the process.
