How to troubleshoot overcurrent or overvoltage on a Vacon Inverter?
- C
  Christopher MooreAug 25, 2025
  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.

What to do if the Vacon Inverter displays a charging switch fault?
- J
  John RogersAug 29, 2025
  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.
