What to do after changing a device of the same type on a Vacon Inverter?
After changing an option board or power unit to a new device of the same type and rating on your Vacon Inverter, reset the system. The device is then ready for use, and the old parameter settings will be used.
What to do if the cooling fan of my Vacon Inverter isn't working?
If the cooling fan of the Vacon Inverter does not start when the ON command is given, contact your local distributor.
What does an unbalance warning mean on a Vacon Inverter?
An unbalance warning on a Vacon Inverter indicates an unbalance between power modules in paralleled units. Should the fault re-occur, contact your local distributor.
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.
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 does 'Safe disable' mean on a Vacon Inverter and how to fix it?
The 'Safe disable' message on a Vacon Inverter indicates that the OPTAF board input has been opened. Cancel Safe Disable if this can be done safely.
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 should I do if my Vacon Inverter shows a system fault?
If your Vacon Inverter displays a system fault, it could be due to component failure or faulty operation. Try to reset the fault and restart the Inverter. If the fault re-occurs, contact your local distributor.
What to do if the Vacon Inverter displays a charging switch fault?
If the Vacon Inverter displays a charging switch fault, it means the charging switch is open when the START command has been given, possibly due to faulty operation or component failure. Reset the fault and restart. Should the fault re-occur, contact your local distributor.
What does IGBT temperature (hardware) fault mean on a 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.
