Helping You Meet OSHA Regulations with Variable Frequency Drives

Training Technology offers a one-day course that is designed to introduce technicians and engineers to common installation practices typical of variable frequency drives. Even though this course stresses the practical aspects of variable frequency drives, it also presents a discussion of AC induction motors, NEC installation, and grounding requirements, as well as applicable OSHA regulations concerning variable frequency drives.
The use of variable frequency drives present the opportunity for many improvements in motor control. In addition to increased motor speed and torque control, VFDs also offer the promise of electrical energy savings, power factor improvements, and reduced mechanical wear and tear on mechanical components. With these improvements also come additional challenges. In addition, the factory default settings for the programmable drive parameters are often not set for the best performance of a particular application. Because of this, the significance of the various programmable parameters will be discussed. Topics will be discussed, such as the following:
  • Harmonics
  • Proper Troubleshooting Tools
  • Electrostatic Discharge
  • Radio Frequency Interference

Learning Outcomes

Upon completion of this course, the participant should be able to do the following:
  • Be Able to Size Input & Output Conductors, Disconnects, Overcurrent Devices, & the Enclosures Related to VFDs
  • Understand Common AC Drive Applications & How to Evaluate Them
  • Be Able to Set & Adjust the Parameters of a VFD for Best System Performance & Energy Savings
  • Be Able to Install the Wiring to VFDs for Optimum System Operation
