Presented by Matthew Conville, P.E.
EASA Technical Support Specialist

This webinar goes through the basics of what accessories may be needed for proper VFD control and power quality add-ons to improve motor driven system reliability. Just buying and installing a VFD isn’t enough to ensure proper operation of a motor driven system in its application, nor does it protect upstream and downstream devices from power quality issues. Topics include:

• Drive accessories
  • Operator panels, encoders, position encoders, communication devices
• Power quality accessories
  • VFD cables and EMC terminations
  • Input reactors and/or isolation transformers
  • Output filters (reactors, dV/dt, sinusoidal, inductive chokes, etc)
• Impacts on AC motors
  • Reduction in SF
  • Winding failures
  • Shaft voltage/bearing currents
  • Turn down ratios

This presentation will be useful for anyone new to VFD applications, or anyone in need of a refresher course.
