4.2.5Searching for a history of changes, using the history function (CWJ)

History function (CWJ):

Automatically searches for 5 latest parameters that are programmed with values different from the standard default setting and displays them in the CWJ. Parameter setting can also be changed within this group CWJ.

Notes on operation

•If no history information is stored, this parameter is skipped and the next parameter “CW” is displayed.

•JGCF and GPF are added respectively to the first and last parameters in a history of changes.
