Why is my Danfoss Controller showing 'Motor ETR overtemperature'?
If the Danfoss Controller is showing 'Motor ETR overtemperature', it means the motor is too hot because it has been loaded more than 100% for too long.
What does 'Brake overload' mean on my Danfoss Controller and how can I fix it?
If the Danfoss Controller displays a 'Brake overload' error, it means that the power transmitted to the brake resistor over the last 120 seconds has exceeded the limit. To resolve this, try decreasing brake energy via lower speed or longer ramp time.
What does it mean when my Danfoss Controller displays a 'Torque limit' error?
If the Danfoss Controller shows a 'Torque limit' error, it means the torque has exceeded the value set in either parameter 4-16 Torque Limit Motor Mode or parameter 4-17 Torque Limit Generator Mode.
What to do if my Danfoss Controller displays a 'Mains phase loss' error?
If the Danfoss Controller shows a 'Mains phase loss' error, it means there is a missing phase on the supply side, or the voltage imbalance is too high. Check the supply voltage.
What does it mean when my Danfoss Controller says 'Inverter overloaded'?
If the Danfoss Controller is indicating 'Inverter overloaded', it signifies that the load has exceeded 100% for an extended period.
What to do if the Danfoss Controller displays a short circuit error?
If the Danfoss Controller indicates a short circuit, it means there is a short circuit either in the motor or on the motor terminals. For J7 units, if this alarm occurs on power-up, check whether power cables are mistakenly connected to the motor terminals.
