ABB · ACS800
¿Qué significa FF89 ?
An overtemperature condition has been detected in the choke of the liquid-cooled R8i inverter module of the ABB ACS800 drive. This indicates that the choke's operating temperature has exceeded its safe limit, which can lead to reduced performance or damage.
Causas comunes
- Malfunction or blockage of the inverter cooling fan, reducing airflow to the choke area.
- Elevated ambient temperature within the drive enclosure or surrounding environment.
- Issues with the liquid cooling system, such as low coolant flow, leaks, or insufficient cooling capacity.
