Parameter Description | Issue 01/06 |
Notice:
When choosing the setting for measurement, observe the following:
1."with parameter change"
means that the values are actually adopted as Pxxxx parameter settings (see common settings above) and applied to the controller as well as being shown in the
2."without parameter change"
means that the values are only displayed, i.e. shown for checking purposes in the

Notice:
If the value identified (Ls = stator inductance) does not lie within the range 50 % < Xs [p. u.] < 500 % fault message 41 (motor data identification failure) is issued.
r0949 provides further information (fault value = 4 in this case).
