- Brand
- Danfoss
- Model / series
- FC 301/302
- Fault code
- 10 verified
- Fault name
- Motor overload temperature verified
- Type
- WARNING/ALARM verified
- Cause
- According to the electronic thermal protection (ETR), the motor is too hot. Select 1 of these options: • The frequency converter issues a warning or an alarm when the counter is >90% if parameter 1-90 Motor Thermal Protection is set to warning options. • The frequency converter trips when the counter reaches 100% if parameter 1-90 Motor Thermal Protection is set to trip options. The fault occurs when the motor runs with more than 100% overload for too long. verified
- Corrective action
- • Check for motor overheating. • Check if the motor is mechanically overloaded. • Check that the motor current set in parameter 1-24 Motor Current is correct. • Ensure that the motor data in parameters 1-20 to 1-25 is set correctly. • If an external fan is in use, check that it is selected in parameter 1-91 Motor External Fan. • Running AMA in parameter 1-29 Automatic Motor Adaptation (AMA) tunes the frequency converter to the motor more accurately and reduces thermal loading. verified
