What is a Sub-Zero Temperature Controller?
Key Takeaway
The most common VFD (Variable Frequency Drive) failure is due to overheating. Overheating can occur when the VFD is operating in high-temperature environments, or when airflow to the drive is restricted. Heat can damage the VFD’s sensitive components, leading to malfunctions or complete failure. To avoid overheating, ensure proper ventilation and keep the surrounding area free from dust and debris.
Another frequent cause of VFD failure is improper voltage levels. High or fluctuating voltage can stress the drive’s internal parts, especially the capacitors, which are vulnerable to damage from electrical surges. Regularly monitoring and maintaining stable input voltage can help extend the VFD’s lifespan and prevent these issues from causing unexpected downtimes in operations.
