A354 / F355 / A357 / F358 / A360 / F361 IGBT P.U/P.V/P.W B2 High Load & Overload fault in WEG CFW900 Drive.
These codes indicate a High Load or Overload on Book 2 IGBTs. This means the Book 2 inverter section is delivering too much current, signaling a mechanical overload.
Cause:
Alarm / Fault of overload on IGBT 2 of phase U, V, or W.
- High current at the inverter output.
Remedy:
Reduce motor load or adjust acceleration parameters to lower active output current levels. Check drive sizing if current remains continuously high.
