What does 'AMA timeout' mean on Danfoss VLT?
If the AMA process took too long to complete, try to restart AMA again.
What does 'AMA motor too big' mean on Danfoss DC Drives?
If the motor is too big for the AMA to operate, check the motor size and frequency converter specifications.
What does 'AMA motor too small' mean on Danfoss DC Drives?
If the motor is too small for the AMA to operate, check the motor size and frequency converter specifications.
What does 'AMA Parameter out of range' mean on Danfoss DC Drives?
If the parameter values are outside of the acceptable range, adjust motor parameters accordingly.
What does 'AMA interrupted by user' mean on Danfoss VLT?
If the AMA has been interrupted by the user, restart AMA after ensuring conditions are safe.
What to do if Danfoss VLT DC Drives show motor thermistor over temp?
If the thermistor might be disconnected, check for motor overheating.
What to do if Danfoss VLT report a short circuit?
If there is a short circuit in the motor or motor wiring, remove power to the frequency converter and repair the short circuit.
How to troubleshoot DC overvoltage in Danfoss VLT DC Drives?
If the intermediate circuit voltage exceeds the limit, connect a brake resistor.
What to do if Danfoss DC Drives show earth (ground) fault?
If there is current from the output phases to earth, either in the cable between the frequency converter and the motor or in the motor itself, remove power to the frequency converter and repair the earth fault.
How to resolve over current in Danfoss VLT?
If the inverter peak current limit is exceeded, check the load connected to the frequency converter and ensure it is within limits.
