What to do if Danfoss VLT AutomationDrive FC 360 DC Drives show Overload T29?
- KKrista MartinezSep 14, 2025
Check the load connected to terminal 29 or remove short-circuit connection.
What to do if Danfoss VLT AutomationDrive FC 360 DC Drives show Overload T29?
Check the load connected to terminal 29 or remove short-circuit connection.
What does 24 V supply low mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
If the 24 V supply is low in Danfoss DC Drives, the 24 V DC may be overloaded.
What does AMA check Unom and Inom mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
If you get an 'AMA check Unom and Inom' error with your Danfoss DC Drives, it indicates a wrong setting for motor voltage and/or motor current.
What does AMA low Inom mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
If you encounter an 'AMA low Inom' error on your Danfoss DC Drives, it means the motor current is too low. Check the settings.
Why is the motor speed unstable in my Danfoss VLT AutomationDrive FC 360 DC Drives?
If the motor speed is unstable, it may be due to incorrect parameter settings. Check the settings in parameter group 6- ** Analog I/O mode.
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 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 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 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 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.
