42 For the correction of a direction vector, the angular displace‐
ment compared to the current direction is greater than the
maximum value specified by the setting data SD41611
$SN_CORR_TRAFO_DIR_MAX.
43 The attempt to write a system variable was rejected because of
missing write rights.
Correction vector
The content of the correction vector is defined by the following parameters
<Corr_Index> and <Corr_Mode>.
If <Corr_Status> = 41, the content of the vector is overwritten (see above).
Data type: REAL
Section whose correction element is to be modified /
index of the orientation axis whose direction vector is to be modified
Data type: INT
The <Corr_Index> parameter is decimal coded (units to tens position):
Units Contains the index of the section or the orientation axis in the sub‐
position: chain.
Tens Refers to the subchain.
