What does a parameter error mean on Danfoss DC Drives?
If your Danfoss DC Drives display a parameter error, it indicates that the parameter is out of range. Set the affected parameter to a valid value.
What to do for an inrush fault in Danfoss DC Drives?
If your Danfoss DC Drives are showing an inrush fault, it means too many power-ups have occurred within a short time period. Let the unit cool to operating temperature.
How to fix brake resistor short circuit in Danfoss VLT HVAC Drive FC 102?
If your Danfoss DC Drives are reporting a brake resistor short circuit, the brake resistor is being monitored during operation. Remove the power to the frequency converter and replace the brake resistor.
What does 'Motor mod. changed' mean on Danfoss VLT HVAC Drive FC 102?
If your Danfoss DC Drives display 'Motor mod. changed', it means the motor selected in parameter 1-11 Motor Model is not correct. Check the motor model.
What does 'Ext. supply' mean on Danfoss VLT HVAC Drive FC 102 DC Drives?
If your Danfoss DC Drives display an 'Ext. supply' error, it means the VLT[®] Extended Relay Option MCB 113 is mounted without external 24 V DC. Either connect a 24 V DC external supply or specify that no external supply is used via parameter 14-80 Option Supplied by External 24VDC.
How to troubleshoot a live zero error on Danfoss VLT HVAC Drive FC 102?
If you're encountering a live zero error with your Danfoss DC Drives, it could be due to broken wiring or a faulty device sending the signal. Check connections on all analog mains terminals.
What to do if control card voltage is less than 10 V in Danfoss VLT HVAC Drive FC 102?
If the control card voltage is less than 10 V in your Danfoss DC Drives, remove some of the load from terminal 50, as the 10 V supply is overloaded. The maximum load should be 15 mA or a minimum of 590 ?.
What does it mean if the brake check failed on Danfoss VLT HVAC Drive FC 102?
If the brake check failed on your Danfoss DC Drives, it means the brake resistor is not connected or not working. Check parameter 2-15 Brake Check.
What to do if motor phase U is missing in Danfoss VLT HVAC Drive FC 102 DC Drives?
If your Danfoss DC Drives report that motor phase U is missing, remove the power from the frequency converter and check motor phase U.
What to do if motor phase V is missing in Danfoss VLT HVAC Drive FC 102?
If your Danfoss DC Drives report that motor phase V is missing, remove the power from the frequency converter and check motor phase V.
