Control card over temperature

What does 65 mean?

The control card temperature has reached its cut-out limit of 80 °C, indicating excessive heat within the control section of the frequency converter. This can lead to erratic behavior, reduced lifespan, or permanent damage to the control card if not addressed. Proper cooling is essential for its reliability.

• Insufficient cooling airflow through the drive due to blocked ventilation openings, dust accumulation on heatsinks, or proximity to heat sources.
• Failure of the internal cooling fan specifically for the control card section or the drive's main cooling fan.
• High ambient temperature in the electrical enclosure exceeding the drive's specified operating range (e.g., >50 °C).
• Excessive current draw by components on the control card itself due to an internal fault, generating additional heat.
• Improper installation or mounting location within the enclosure, restricting heat dissipation or exposing to radiant heat.

Click steps to track your progress.

1. 1

   Verify the drive's cooling fan (typically visible through vents) is operational, free of obstructions, and not clogged with dust.

2. 2

   Clean any dust or debris from the drive's heatsinks and ventilation openings using compressed air.

3. 3

   Measure the ambient temperature inside the electrical enclosure and ensure it is within the drive's specified operating limits.

4. 4

   Check for proper air circulation inside the enclosure, ensuring intake and exhaust vents are not blocked and enclosure fans are operating.

5. 5

   Reduce the drive's continuous load or output current (if permissible) to decrease overall heat generation.

6. 6

   Inspect the control card for any visible signs of component stress or discoloration that could indicate an internal fault.
