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.

Complete Troubleshooting Guide

1. 1

   Immediately power down the drive and isolate it from the mains supply.

2. 2

   Contact the Siemens Service Department for expert diagnosis and repair.

3. 3

   Prepare for the replacement of the inverter power module, as this typically indicates a non-repairable hardware failure.
