Cause : component replacement identified and save required comes when the "Safety Integrated" function integrated in the drive has identified that a component has been replaced. No additional fault response is initiated, therefore operation of the particular drive is not restricted.

When safety functions are active, after a component has been replaced it is necessary to carry out a partial acceptance test.

- save all parameters (p0977 = 1 or p0971 = 1 or "copy RAM to ROM").
- acknowledge fault (e.g. BI: p2103).
