How to match drives (VFDs, VSDs) to the motor
Size a variable-speed drive (VSD) for the application, and ask if a general-purpose drive will do or if more embedded intelligence is needed. Do you need a VSD, variable frequency drive (VFD) or adjustable speed drive (ASD)? (Trick question)
Top 5 VFD parameter changes explained
Programming variable frequency drives (VFDs) to fit most industrial applications require only the most basic settings to operate the motor. Understand these 5 VFD parameter changes to optimize VFD programming to fit most motor-drive applications.
10 essential maintenance and troubleshooting tips for VFDs
A properly maintained variable frequency drive (VFD) can provide decades and cost-effective service. Making VFD inspections and maintenance part of facility oversight can improve outcomes.
