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.
Reparasjonssteg & Sjekkliste
Klikk på steg for å spore fremgangen.
- 1
Verify that the maximum ambient temperature around the drive enclosure has not been exceeded.
- 2
Check the operation of the cooling fan (e.g., for obstructions, wear, or failure).
- 3
Check for excess load on the motor, which would increase drive current and heat generation.
