Controlling VFDs with Manual Inputs

To increase the flexibility of a motor control system, a variable frequency drive (VFD) is a common device that solves many motor control problems. In this article, learn how to control manual input of VFDs. Variable frequency drives solve many of the challenges associated with driving three-phase motors including adjustable speeds, networking many motors together … Read more

Understanding the Basics of Pulse Width Modulation (PWM)

Power delivered to devices can be changed by raising or lowering the voltage and current. But this method does not always produce intended results. Pulse width modulation (or PWM) can be used to better control variable loads. What is Pulse Width Modulation? Load devices are designed to run efficiently and perform their respective tasks when … Read more
