Operating Guide
12.12.51 Fault 14 - AC drive overtemperature, Subcode S1 - Overtemperature warning in unit,
board, or phases
Cause
Overheating detected in AC drive.
Heat sink temperature is over 90 °C (194 °F). Overtemperature alarm is issued when the heat sink temperature goes over 85 °C
(185 °F).
In 525–690 V, FR6: Heat sink temperature is over 77 °C (170.6 °F). Overtemperature alarm is issued when the heat sink temperature
goes over 72 °C (161.6 °F).
Troubleshooting
•
Do a check of the actual amount and flow of cooling air.
•
Examine the heat sink for dust.
•
Do a check of the ambient temperature.
•
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
•
For FR10-FR11 Standalone: check door filters, and clean or replace if needed.
