36

Overtemperature

Danfoss · VLT 2800 Variable Speed Drive

What does 36 mean?

The heatsink temperature has risen above a critical threshold (167-185°F / 75-85°C). The drive initially issues a warning, and if the temperature continues to rise, it automatically reduces the switching frequency to mitigate heating. Prolonged high temperatures can lead to component degradation and drive failure.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Ensure proper ventilation and airflow around the drive enclosure.

  2. 4

    Check for excessive drive loading or high switching frequencies that might contribute to overheating.
