What does Ctrl. word TO mean in Danfoss DC Drives?
This indicates a loss of communication to the frequency converter. See parameter group 8-0* General Settings for troubleshooting.
What does 'Illegal power section configuration' mean on Danfoss DC Drives?
The message 'Illegal power section configuration' on Danfoss DC Drives indicates an internal fault.
What does 'Inverter over-load' mean on Danfoss VLT CDS 803 DC Drives?
An 'Inverter over-load' message on Danfoss DC Drives means the drive has experienced more than 100% load for an extended period.
What does 'Earth Fault' mean on Danfoss DC Drives?
An 'Earth Fault' on Danfoss DC Drives suggests a discharge from output phases to ground.
Why Danfoss DC Drives show 'DC over volt'?
Danfoss DC Drives display 'DC over volt' because the DC-link voltage exceeds the limit.
Why Danfoss DC Drives show 'DC under volt'?
Danfoss DC Drives display 'DC under volt' because the DC-link voltage drops below the voltage warning low-limit.
What to do if Danfoss DC Drives show 'U phase loss'?
If Danfoss DC Drives display 'U phase loss', it means motor phase U is missing. Check the phase.
What to do if Danfoss VLT CDS 803 show 'V phase loss'?
If Danfoss DC Drives display 'V phase loss', it means motor phase V is missing. Check the phase.
What to do if Danfoss VLT CDS 803 DC Drives show 'W phase loss'?
If Danfoss DC Drives display 'W phase loss', it means motor phase W is missing. Check the phase.
What does 'Fan Fault' mean on Danfoss DC Drives?
The 'Fan Fault' message on Danfoss DC Drives indicates that the heat sink cooling fan is not working (only on 400 V, 30 kW (40 hp) units).
