What to do if Danfoss DC Drives power fuses open or circuit breaker trips?
If the power fuses open or the circuit breaker trips, it could be due to a phase-to-phase short, motor overload, or loose connections. Eliminate any shorts detected. Review the specifications for the application to address potential motor overload. Ensure all connections are tightened.
How to fix a Danfoss VLT AutomationDrive FC 360 DC Drives motor that is not running?
If the motor is not running, there might be several causes. First, check if the LCP stop is active and press [Auto On] or [Hand On] to run the motor. Second, ensure a valid start signal is applied. Third, verify that the motor coast signal is not active by applying 24 V on terminal 27 or programming this terminal to No operation. Finally, confirm that the reference signal source is correctly programmed, the wiring is correct, the terminals are scaled properly, and the reference signal is valid.
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.
What to do if the Danfoss Controller shows an overcurrent error?
If the Danfoss Controller displays an overcurrent error, it means the inverter peak current limit has been exceeded. For J1–J6 units, if this happens when powering up, verify that the power cables are correctly connected to the motor terminals.
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 '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 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 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 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 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.
