What causes IGBT temperature (hardware) fault on Vacon Inverter?
An IGBT temperature (hardware) fault on your Vacon Inverter indicates that the IGBT Inverter Bridge overtemperature protection has detected too high a short term overload current. Check the loading.
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.
How to troubleshoot overcurrent or overvoltage on a Vacon Inverter?
If your Vacon Inverter is showing an overcurrent or overvoltage error, it means the AFE has detected too high a current in the cables or the DC-link voltage has exceeded the drive limit, possibly due to high overvoltage spikes in the supply. Check the input voltage.
