PLC vs VFD Motion Control – When Should Each Be Used? PLC and VFD technologies are both essential in modern industrial automation, but they do very different jobs. A PLC controls logic, sequencing, inputs, outputs, and machine decisions, while a…
How Encoders Work with VFDs – Closed Loop Speed & Position Control In modern industrial automation, achieving precise motor control is critical for performance, efficiency, and reliability. While standard VFD (variable frequency drive) systems can control motor speed effectively, adding…
VFD Output Filters Explained – dV/dt vs Sine Wave Filters VFD output filters play an important role in protecting motors, reducing electrical stress, and improving reliability in variable frequency drive installations. When a motor is powered by an inverter drive,…
Long Motor Cables with VFDs – When Do You Need a dV/dt Filter? Variable frequency drives (VFDs) have become the standard method for controlling electric motors in modern industrial systems. They provide precise speed control, improved energy efficiency, and smoother…
VFD Carrier Frequency Explained – Noise, Efficiency & Motor Heating Carrier frequency is one of the most important yet often misunderstood settings inside a variable frequency drive (VFD). It plays a major role in how quietly the motor runs, how…
How to Tune a VFD for Optimal Motor Performance (Step-by-Step Guide) Tuning a variable frequency drive (VFD) correctly is one of the most important steps in achieving smooth motor operation, strong torque performance, reduced mechanical stress, and long-term system reliability.…
Profinet vs EtherNet/IP vs Modbus TCP for VFDs & PLCs Profinet vs EtherNet/IP vs Modbus TCP – Which Industrial Network Should You Use (And Why It Matters for VFDs + PLCs) If you’re selecting a network for VFDs, PLCs, remote…
Digital vs Analog VFD Control – Pros, Cons, and Real-World Wiring Examples Explained Modern Variable Frequency Drives (VFDs) can be controlled in several different ways. The two most common methods are analog control (0–10V / 4–20mA signals) and digital control…
