What to do if Vacon Inverter shows Parameter Fault?
- AAnthony WatkinsSep 10, 2025
If your Vacon Inverter shows a Parameter Fault, check the parameters value.
What to do if Vacon Inverter shows Parameter Fault?
If your Vacon Inverter shows a Parameter Fault, check the parameters value.
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.
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 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.
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 to do if there is a problem in application software of Vacon Inverter?
If there is a problem in the application software of your Vacon Inverter, contact your distributor. If you are the application programmer, check the application program.
What does an EEPROM checksum fault mean on a Vacon Inverter?
An EEPROM checksum fault on a Vacon Inverter indicates a parameter save fault, faulty operation, or component failure. Should the fault re-occur, contact your local distributor.
What to do if my Vacon Inverter displays a microprocessor watchdog fault?
If your Vacon Inverter displays a microprocessor watchdog fault, it could be due to faulty operation or component failure. Reset the fault and restart. Should the fault re-occur, contact your local distributor.
What to do after changing a device type on a Vacon Inverter?
After changing an option board or power unit to a different type or rating on your Vacon Inverter, reset the system. Set the option board parameters again if an option board was changed, and set the converter parameters again if the power unit was changed.
How to resolve 'Start-up prevented' error on Vacon Inverter?
If the Vacon Inverter displays 'Start-up prevented', it means the start-up of the drive has been prevented because the run request is ON when a new application is loaded to the drive. Cancel prevention of start-up if this can be done safely, or remove the run request.
