PRECISION DRIVE SYSTEMS

Seminar Overview

This hands on seminar introduces the student to world of variable frequency drives. Students will learn how to improve VFD control and efficiency, troubleshoot and fix VFDs, reduce equipment downtime, size a VFD for a specific application, eliminate chronic VFD problems, lower the cost of VFD operation, and alleviate the need for hiring costly outside service contractors, all while establishing a culture of safe work practices among employees.

This one day seminar is just $890 provided at customer location.

Discussion Topics

Variable Frequency Drive training focuses on the background and basics of using VFDs; where and how they are used in the workplace.  The class discusses how VFDs can improve efficiency, safety and cost savings and discusses the various types of VFDs.

WHAT VFD’s DO

• Motion Control / Motor Speed
• Air Flow / Liquid Flow / Pressure Control
• Eliminates the need for: 
• Variable Transmission or Sheave
• Variable Vanes or Dampers on Fans
• Variable Valves on Pumps

BENEFITS OF USING A VFD

• Energy Savings
• Easier Maintenance
• Enhanced System Monitoring

LOAD TYPES

• Constant Torque – Conveyors, Positive Displacement Pumps, Extruders, Lathe Machines, Milling Machines,
• Variable Torque – Centrifugal Fans or Pumps, Routers, Blowers, Fans

INSTALLATION OF A VFD

• Environmental Concerns
• Clearances
• Conduit Entry
