What to do if a Vacon Inverter reports an earth fault?
If your Vacon Inverter is reporting an earth fault, it means the current measurement has detected that the sum of phase currents is not zero, likely due to insulation failure in the cables. Check the cables.
What causes a 'Line Sync Fail' on a Vacon Inverter?
A 'Line Sync Fail' on your Vacon Inverter indicates a missing input line phase. To resolve this, check the supply voltage, fuses, and cable.
Why does my Vacon Inverter show an input phase supervision fault?
An input phase supervision fault on your Vacon Inverter indicates a missing input line phase. Check the supply voltage, fuses, and cable.
What to do if my Vacon Inverter shows an undervoltage error?
If the Vacon Inverter displays an undervoltage error, it means the DC-link voltage is below the fault voltage limit, possibly due to low supply voltage, an internal fault, or a broken input fuse. In case of a temporary supply voltage break, reset the fault and restart the frequency converter. Check the supply voltage, and if it's adequate, an internal failure may have occurred. Also, check the input fuses and the DC charge function.
