What to do if Danfoss DC Drives says 'AMA motor too small'?
- WWilliam RichardsSep 9, 2025
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 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 DC Drives?
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 DC Drives?
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.
What to do if Danfoss Control Unit is in operation but not responding to control commands?
If the Danfoss Control Unit is running but ignoring control commands, try using the [Hand On] control or reference values from the LCP.
How to troubleshoot motor thermistor overtemp in Danfoss VLT HVAC Drive FC 102?
If you are getting a motor thermistor overtemp warning on your Danfoss DC Drives, check whether the thermistor is disconnected. Also, check for motor overheating and if the motor is mechanically overloaded. When using terminal 53 or 54, ensure the thermistor is correctly connected between either terminal 53 or 54 (analog voltage input) and terminal 50 (+10 V supply), and that the terminal switch for 53 or 54 is set for voltage. If using terminal 18, 19, 31, 32, or 33 (digital inputs), ensure the thermistor is correctly connected between the digital input terminal used (digital input PNP only) and terminal 50.
How to fix Danfoss Control Unit that does not react to any control signal?
If the Danfoss Control Unit isn't responding to any control signals, try pressing either the [Auto On] or [Hand On] button.
What causes DC overvoltage in Danfoss VLT HVAC Drive FC 102 DC Drives and how to fix it?
If your Danfoss DC Drives display a DC overvoltage error, it indicates that the DC-link voltage exceeds the limit. Here are some potential solutions: * Connect a brake resistor. * Extend the ramp time. * Change the ramp type. * Activate the functions in parameter 2-10 Brake Function. * Increase parameter 14-26 Trip Delay at Inverter Fault. If the alarm/warning occurs during a power sag, consider using kinetic back-up (parameter 14-10 Mains Failure).
What to do if Danfoss VLT HVAC Drive FC 102 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.
