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.

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.
12.12.53 Fault 14 - AC drive overtemperature, Subcode S4 - Overtemperature on ASIC board or
driver boards
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.
12.12.54 Fault 15 - Motor stalled
Cause
The motor stalled.
It is possible to set different responses in the application for this fault. See parameter group Protections.
Troubleshooting
Check the motor and the load.
Insufficient motor power, check motor stall protection parameterization.
