What does Inrush fault mean on Danfoss DC Drives?
See section 8.2 General Specifications for the allowed number of power ups within one minute, if too many power ups have occurred within a short time period.
How to fix Earth fault in Danfoss DC Drives?
If there is a discharge from the output phases to earth, either in the cable between the Danfoss DC Drives frequency converter and the motor or in the motor itself, turn off the frequency converter and remove the earth fault.
What causes Short-circuit in Danfoss DC Drives and how to resolve it?
If there is short-circuiting in the motor or on the motor terminals, turn off the Danfoss DC Drives frequency converter and remove the short-circuit.
Why Danfoss DC Drives shows Motor ETR over temperature and what to do?
If the motor is overloaded by more than 100% for too long, check that the motor 1-24 Motor Current is set correctly.
What to do if Danfoss DC Drives reports Mains failure?
If the supply voltage to the Danfoss DC Drives frequency converter is lost and 14-10 Mains Failure is NOT set to OFF, check the fuses to the frequency converter.
What to do if Danfoss DC Drives reports Brake chopper fault?
Turn off the Danfoss DC Drives frequency converter and remove the brake resistor.
What to do if Danfoss DC Drives shows Internal fan fault?
If the fan warning is active, ensure the fan is running/mounted.
How to fix Brake resistor short-circuited error on Danfoss DC Drives?
Turn off the Danfoss DC Drives frequency converter and replace the brake resistor.
What to do for DC link voltage high on Danfoss DC Drives?
Connect a brake resistor, extend the ramp time, activate functions in 2-10 Brake Function, or increase 14-26 Trip Delay at Inverter Fault.
What causes Live zero error on Danfoss DC Drives?
Check the signal on terminal 53 or 54; it should not be less than 50% of the value set in 6-10 Terminal 53 Low Voltage, 6-12 Terminal 53 Low _Current, 6-20 Terminal 54 Low Voltage, or 6-22 Terminal 54 Low _Current respectively.
