Frequency converter overtemperature
Vacon · NXS NXP Drive
What does 14 mean?
The drive's heatsink temperature has exceeded its maximum safe operating limit (e.g., 90 °C or 77 °C for specific models). This is commonly caused by inadequate cooling airflow, accumulation of dust on heatsinks, high ambient temperatures, or an excessive switching frequency relative to the motor load. Sustained overtemperature will severely degrade and damage the drive's power components.
Complete Troubleshooting Guide
- 1
Check the cooling air intake and exhaust vents for obstructions and ensure sufficient airflow.
- 2
Clean the heatsink fins and cooling fans to remove any dust or debris build-up.
- 3
Verify that the ambient temperature around the drive is within the specified operating limits.
- 4
Consider reducing the drive's switching frequency if it is excessively high for the current operating conditions and motor load.
