Variable Frequency Drives and Servos ACIM 5040

Automated Controls Installation & Maintenance Course

Course details

This course will familiarize students with installation and operational requirements for electrical machines with variable-frequency drives. Students will be introduced to applications of variable-frequency drives (VFDs), including their installation needs, classifications and harmonic considerations. The drives will be utilized on standalone and micro-processor-based systems programmable logic controllers (PLCs)/programmable automation controllers (PACs). A significant part of the course is dedicated to application activities that reinforce the theory.


  • TELC 0130 Basic Motor Control and/or successful completion of Electrical Apprenticeship Level 2 or 3 or 4 program within the last 5 years. Electrical Journeyperson Certificate, Electrical Engineering Degree and/or Electrical Engineer Practitioner are also acceptable.
