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.
What does AMA big motor mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
If you receive an 'AMA big motor' error with your Danfoss DC Drives, it means that the motor is too large for the AMA to operate.
What does AMA small motor mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
If you receive an 'AMA small motor' error with your Danfoss DC Drives, it indicates the motor is too small for the AMA to operate.
How to reduce acoustic noise or vibration in Danfoss DC Drives?
Acoustic noise or vibration can be caused by resonances in the motor/fan system. Check if noise and/or vibration have been reduced to an acceptable limit. Also, turn off overmodulation in parameter 14-03 Overmodulation. Increase resonance damping in parameter 1-64 Resonance Dampening.
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.
