Powerstack fault

What does F00022 mean?

A critical hardware fault has occurred within the inverter's power stack, likely due to a short circuit in an IGBT or the chopper circuit, leading to excessive DC-link current. This indicates severe internal damage to the inverter power components and requires replacement to prevent further system failure and potential safety risks.
