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 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 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 causes External Trip on Vacon Inverter?
An External Trip on a Vacon Inverter is caused by a trip signal from a digital input. Remove the fault situation from the external device.
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 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 if Vacon Inverter shows AC voltage on line side is below the min limit?
If your Vacon Inverter indicates that the AC voltage on the line side is below the minimum limit, check the AC Voltage.
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.
