Heatsink Overtemperature

Allen-Bradley · PowerFlex 700

Hva betyr 8 ?

The heatsink temperature exceeds 100% of the [Drive Temp] threshold. This indicates that the drive's cooling system is unable to dissipate heat effectively, risking thermal damage to the power components.

Vanlige årsaker

  • Drive heatsink temperature exceeds operational limits.
  • Cooling fan failure or obstruction.
  • High ambient temperature around the drive.
  • Excessive drive load causing increased heat generation.

  1. 1

    Verify that the maximum ambient temperature around the drive enclosure has not been exceeded.

  2. 2

    Check the operation of the cooling fan (e.g., for obstructions, wear, or failure).

  3. 3

    Check for excess load on the motor, which would increase drive current and heat generation.
