How to get a variable frequency drive (VFD) running
Here we cover the specifics of how variable frequency drives (VFD) operate and ways to simplify their installation and setup. By Bob Bonczar, Yaskawa America | Technical Training Services Variable frequency drives or VFDs — which we call simply drives in this context — operate in a wide array of industries. They’re often behind the […]
FAQ: How are PID parameters configured for variable frequency drives?
Using proportional-integral-derivative (PID) control with variable frequency drives (VFDs) is common when a process set point—such as temperature, pressure, flow, or speed—needs to be precisely controlled. In fact, many VFDs are now supplied with an integrated PID controller. PID controller terms Configuring the PID parameters for fast response and minimum overshoot (referred to as tuning […]

What is a VFD (Variable Frequency Drive)? Technical Summary
What is a VFD? Variable-frequency drives, or VFDs, are a means of controlling the speed of an ac motor, typically an ac induction motor. It does so by varying the frequency of the power source. VFDs operate by switching their output devices, which can be transistors, IGBTs, or thyristors, on and off. VFDs can be […]
