This course covers all aspects of working with modern variable frequency drives (VFDs).Generic terms that apply to all VFD manufacturers are covered. Wiring, programming and commissioning of different manufacturers are covered. In depth VFD setup is covered using professional drive commissioning software that is included free in the course. The student can follow along and adjust parameters using the software. Also included and demonstrated is VFD simulation software that replicates exactly the front panel buttons of a modern VFD. The student is walked through the steps of setting up a drive and important points learned over the years are covered. Periodic inspection and maintenance of VFDs and electric motors is covered. The tasks involved in maintaining and troubleshooting equipment are covered.Other important information covered in the course include:Working safely with VFDs and the hazards associated with VFD commissioningVFD power and control wiringLine, load and DC link reactorsThe DC busSink & source wiringVFD digital and analog inputs and outputsVFD motor brakingInverter rated motorsMotor turn down ratiosBasic VFD theory of operationBasic Motor theory of operationConstant torque and variable torque modesVolts per hertz ratiosPump & fan applicationsAuto-tuningVFD wiring schematics are explained and demonstrated with design software2-wire control transition and run at power up 3- wire control with forward and reverse
