Heatsink OvrTmp

What does F008 mean?

The temperature of the drive's heatsink or power module has risen above its predefined safe operating threshold. This indicates inadequate cooling for the power components, potentially caused by environmental factors, blocked airflow, or a faulty cooling fan. Sustained overheating shortens component lifespan.

• Blocked or dirty cooling fins on the drive's heatsink, significantly restricting airflow and heat dissipation.
• Failed or obstructed cooling fan within the drive or the drive cabinet, leading to insufficient forced air convection.
• Ambient temperature in the control cabinet exceeding the drive's maximum specified operating temperature (e.g., >50°C).
• Inadequate cabinet ventilation or failure of the cabinet's air conditioning system, causing heat buildup.
• Continuous operation of the drive at or above its nominal current rating, generating excessive heat for an extended period.

Click steps to track your progress.

1. 1

   Clean the drive's heatsink fins and cooling fan blades with compressed air, ensuring unobstructed airflow through the heatsink.

2. 2

   Verify the drive's internal cooling fan is operating correctly (e.g., spinning at rated speed) and is not obstructed or seized.

3. 3

   Measure the ambient temperature inside the control cabinet at the drive's air intake vents, ensuring it is within the drive's specified operating range (e.g., 0-50°C).

4. 4

   Check the cabinet ventilation system (e.g., filter fans, AC unit) for proper operation and ensure all air filters are clean and unobstructed.

5. 5

   Monitor the drive's heatsink temperature (P0-07 [Heatsink Temperature]) via the drive display during operation to observe temperature trends.
