Result bit
Selection:
● No (no result bit)
● Yes (result bit of calculated vectors)
● Yes, can be edited (result bit and offset of calculated vectors)
For the result bit, see Section "Result bit".
The following displays - "Rotary axis", "Normalizing" and, where applicable, "Position value" -
are all functionally associated with one another.
Rotary axis
Displays the name of rotary axis 1/rotary axis 2 (if this exists) of the measured kinematics.
Normalizing (Normalizing the vertice of the calculated vectors)
"Normalizing" refers to setting a component of a linear vector to a preferred value of a linear
axis position (in X, Y or Z). Using normalizing, kinematic vectors that have been determined
can be calculated with reference to mechanical fixed positions specific for a machine (e.g. Z
position of the table surface). This allows comparable swivel data records to be written to
within a machine series. The measured kinematic data are therefore independent of
mechanically specified measuring conditions (mounting position of the calibration ball). The
measured rotary axis vectors are taken into account in scaling.
Example:
Z component of the linear vector of rotary axis C is always referred to the upper edge of the
table at Z = 0.
i.e., rotary axis C/normalizing Z/position value 0
Selection:
● No (default) (no normalizing)
● Z, Y, X (normalizing of axes X, Y, or Z in line with an assigned position value)
For coding, see _MVAR
Position value (Normalizing position value)
Entry field can only be seen if "Normalizing" is shown on Z, Y, X.
Parameter:
● Rotary axis 1 normalizing _SETV[5]
● Rotary axis 2 normalizing _SETV[6]
