Diagnostics and Troubleshooting
Faults codes that will be cleared as soon as their causes disappear
The USF fault can be cleared remotely by means of a logic input (parameter Detected fault reset assignment rSF page 91).
(1) When the CFI is present in the past fault menu, it means the configuration has been interrupted or is not fully finished.

HMI block changed

When an HMI block is replaced by an HMI block configured on a drive with a different rating, the drive locks in Incorrect configuration CFF
fault mode on power-up. If the card has been deliberately changed, the fault can be cleared by returning to factory setting.
