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.
What to do if Vacon Inverter shows Division by zero in application?
If a division by zero has occurred in the application program of your Vacon Inverter, contact your distributor if the fault re-occurs while the converter is in run state.
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.
What to do if Vacon Inverter shows option board in slot B,C,D or E has status “Communication Lost”?
If your Vacon Inverter shows that an option board in slot B, C, D, or E has a status of “Communication Lost”, check the board and slot. Contact the nearest Vacon distributor.
What to do if Fieldbus Board of Vacon Inverter has status “Faulted”?
If a Fieldbus card in slot D or E of your Vacon Inverter has a status of “Faulted”, check the installation. If the installation is correct, contact the nearest Vacon distributor.
What to do if Vacon Inverter shows AC voltage on line side is above the max limit?
If your Vacon Inverter indicates that the AC voltage on the line side is above the maximum limit, check the AC Voltage.
What to do if Vacon Inverter shows Input Switch in wrong state?
If your Vacon Inverter indicates that the Input Switch is in the wrong state, check the input Switch.
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.
