What to do if Danfoss DC Drives show control card over temperature?
If the cutout temperature of the control card is exceeded, check that the ambient operating temperature is within limits.
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 does 'missing motor' mean on Danfoss DC Drives?
If an under-load condition was detected, inspect the system for proper operation.
What to do if Danfoss DC Drives show heatsink temperature low?
If the frequency converter is too cold to operate, increase the ambient temperature of the unit.
What does 'dry pump' mean on Danfoss DC Drives?
If a no-flow condition in the system with the frequency converter operating at high speed indicates a dry pump, troubleshoot the system and reset the frequency converter after the fault has been cleared.
How to resolve a brake chopper fault in Danfoss DC Drives?
If the brake transistor is monitored during operation and if a short circuit occurs, the brake function is disabled, remove power to the frequency converter and remove the brake resistor.
What to do if Danfoss VLT DC Drives show inrush fault?
If too many power-ups have occurred within a short time period, let the unit cool to operating temperature.
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 report motor phase V missing?
If motor phase V between the frequency converter and the motor is missing, remove power from the frequency converter and check motor phase V.
