2. In the Alignment panel, select Moving as the Type.
3. Clear the previous alignment if present.
Press the Clear Alignment button to remove an existing alignment.
4. Select an alignment Target.
l Select one of the disk Disk options to use a disk as the alignment reference.
l Select Bar to use a custom calibration bar.
Configure the characteristics of the target (bar dimensions and reference hole layout); for details
on alignment bars, see Alignment Targets on page 28.
Degrees of Freedom: In moving bar alignment, three options are available, which are
combinations of different types of alignments. X, Y, and Z compensate for offsets on the X, Y, and Z
axes, respectively. YAngle and ZAngle compensate for rotation around the Yand Zaxes,
respectively. Compensating for Xangle rotation is currently only possible by manually setting the
rotation in the Transformations panel.
The Y offset, X angle, and Z angle transformations cannot be non-zero when
Uniform Spacing is unchecked. Therefore, when aligning a sensor using a bar
alignment target with Uniform Spacing unchecked, set the Degrees of Freedom
setting to X, Z, Y Angle, which prevents these transformations from being non-
zero.
On sensors aligned using Z angle or X angle, and to a lesser extent Y offset, CPU
usage increases when scanning, which reduces the maximum scan speed.
Artifacts may appear in scan data on sensors aligned using Z angle or X angle if
encoder trigger spacing is set too high (resulting in a low sampling rate).
