MOD BOARD T

¿Qué significa FF88 ?

An overtemperature condition has been detected in the AINT board of the inverter module within the ABB ACS800 drive. This indicates that the operating temperature of this critical control board has exceeded its safe limit, posing a risk of component damage.

• Malfunction or blockage of the inverter cooling fan, leading to insufficient airflow.
• Elevated ambient temperature within the drive enclosure or surrounding environment.
• Accumulation of dust or debris on the AINT board or heatsinks, reducing cooling efficiency.

1. 1

   Check the inverter cooling fan for proper operation, ensuring it rotates freely and provides adequate airflow.

2. 2

   Verify the ambient temperature around the ACS800 drive enclosure, ensuring it is within specified operating limits.

3. 3

   Clean any accumulated dust or debris from the heatsink and ventilation ducts of the inverter module.

4. 4

   Ensure sufficient clearance around the drive for proper air circulation and heat dissipation.
