Course objective and description:  

The objective of this AC Drive (VFD) seminar is to provide maintenance personnel and technicians with useful information about AC drives that can be immediately put to work on the job. The functions and testing procedures of the major drive components are examined in detail. The hands-on training also includes connecting a 9-lead, 3-phase motor to an AC drive and programming the drive for proper operation. The student will start-up and operate the drive in the classroom and will be faced with programming challenges. Upon completion of this seminar the student will be able to troubleshoot, repair, program, and solve most drive related problems including programming and start-up of new or replacement AC drives. While the information provided in this seminar can be applied to all modern brands of PWM type AC drives, the hands-on drive programming will be performed on Allen-Bradley AC drives.

Course topics include:   

  • Evolution of adjustable speed drives
  • AC & DC electrical terminology
  • AC motor theory
  • Choosing the correct motor
  • AC drive (VFD) theory
  • AC drive terminology
