Variable Frequency Drives (VFDs) have become essential in optimizing motor control, reducing energy consumption and extending equipment life in industrial automation systems. VJ Pamensky (WEG Canada) supports businesses across industries like mining, oil & gas and manufacturing by helping them select, install and maintain VFDs for optimal performance. In this blog, we explore the most common VFD issues and how to resolve them to ensure reliability and efficiency.

1. Reduce Harmonics by Using the Right Filter

VFDs can introduce harmonic distortion into a facility’s electrical system, especially in high-load environments. This distortion leads to equipment overheating, nuisance tripping and reduced power factor.

Solutions:

2. Prevent Motor Insulation Stress from Long Cables

Extended cable lengths between VFDs and motors can lead to voltage spikes due to reflected wave phenomena. These spikes often stress or damage motor insulation, especially in older motors.

Solutions:

VJ Pamensky can recommend compatible filters and motor types for your cable setup.

3. Reduce VFD Overheating with Proper Ventilation

Overheating is common when VFDs are installed in tight or poorly ventilated enclosures. This issue worsens in hot industrial environments and can lead to premature failure.

Solutions:

VJ Pamensky helps customers assess installation conditions to prevent thermal issues.

4. Eliminate EMI in Control Setups

High-frequency switching in VFDs can cause electromagnetic interference (EMI), which may disrupt nearby sensitive equipment.

Solutions:

5. Avoid Programming Mistakes with Proper Commissioning

Incorrect VFD parameter settings — such as acceleration time, torque limits or braking functions — can lead to operational inefficiencies or mechanical damage.
