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.
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 it mean when my Danfoss Controller displays a 'DC overvoltage' error?
If the Danfoss Controller displays a 'DC overvoltage' error, it means the intermediate circuit voltage exceeds the limit.
What does it mean when my Danfoss Controller displays a 'DC undervoltage' error?
If the Danfoss Controller displays a 'DC undervoltage' error, it means the intermediate circuit voltage has dropped below the voltage warning low limit.
What does it mean if my Danfoss Controller is showing a 'Current limit' error?
If the Danfoss Controller displays a 'Current limit' error, it indicates a frequency converter overload.
What does it mean when my Danfoss Controller displays 'Motor thermistor overtemperature'?
If the Danfoss Controller indicates 'Motor thermistor overtemperature', it means the thermistor or thermistor connection is disconnected.
What does 'Earth fault' mean on my Danfoss Controller?
If the Danfoss Controller displays an 'Earth fault' error, it means there is a discharge from output phases to ground.
What does 'Control word timeout' mean on my Danfoss Controller?
If the Danfoss Controller displays a 'Control word timeout' error, it means there is no communication to frequency converter.
What does 'Live zero error' mean on my Danfoss Controller?
If the Danfoss Controller displays a 'Live zero error', it means the signal on terminal 53 or 54 is less than 50% of the value set in parameter 6-10 Terminal 53 Low Voltage, parameter 6-12 Terminal 53 Low Current, parameter 6-20 Terminal 54 Low Voltage, and parameter 6-22 Terminal 54 Low Current.
What does 'No motor' mean on my Danfoss Controller?
If the Danfoss Controller indicates 'No motor', it means that no motor has been connected to the output of the frequency converter, or one motor phase is missing.
