Check the motor size if you are getting the 'AMA motor too big' error on your Danfoss DC Drives.
What to do if Danfoss VLT AutomationDrive FC 300 report a mains phase loss?
If you are experiencing a mains phase loss with your Danfoss DC Drives, it means a phase is missing on the supply side, or the mains voltage imbalance is too high. Check the supply voltage and supply currents to the frequency converter.
What to do if Danfoss VLT AutomationDrive FC 300 says 'AMA motor too small'?
Check the motor size if you are getting the 'AMA motor too small' error on your Danfoss DC Drives.
What to do if Danfoss DC Drives says 'AMA parameter out of range'?
If you receive an 'AMA parameter out of range' error on your Danfoss DC Drives, check the settings.
What to do if AMA interrupted by user on Danfoss VLT AutomationDrive FC 300?
If the AMA was interrupted by the user on your Danfoss DC Drives, try to restart AMA again.
How to troubleshoot tracking error on Danfoss VLT AutomationDrive FC 300?
If you're experiencing a tracking error with your Danfoss DC Drives, it means the difference between the set point value and the actual value has exceeded the limit. Investigate the mechanics around the load and motor.
What does illegal power section configuration mean on Danfoss DC Drives?
If your Danfoss DC Drives displays an illegal power section configuration, it means the scaling card has an incorrect part number or is not installed. Contact Danfoss supplier.
How to fix a short circuit in Danfoss VLT AutomationDrive FC 300 DC Drives?
If your Danfoss DC Drives indicate a short circuit, it means there is short-circuiting in the motor or motor wiring. Remove the power to the frequency converter and repair the short circuit.
What causes motor overload temperature in Danfoss VLT AutomationDrive FC 300 DC Drives?
To address a motor overload temperature issue in Danfoss DC Drives: * Check for motor overheating. * Check if the motor is mechanically overloaded. * Check that the motor current set in parameter 1-24 Motor Current is correct. * Ensure that the motor data in parameters 1-20 to 1-25 is set correctly. * If an external fan is in use, check that it is selected in parameter 1-91 Motor External Fan. * Running AMA in parameter 1-29 Automatic Motor Adaptation (AMA) tunes the frequency converter to the motor more accurately and reduces thermal loading.
Why am I getting an inverter overload on my Danfoss DC Drives?
If your Danfoss DC Drives are showing an inverter overload, it means the frequency converter has run with more than 100% overload for too long. Compare the output current shown on the LCP with the frequency converter rated current and with the measured motor current. Also, show the thermal frequency converter load on the LCP and monitor the value.
