Horizontal shaft alignment

3. Soft foot
If the machine suffers from excessive soft foot, the Live Move function may be
hampered by the fact that the machine changes position on its own every time the
bolts are loosened and tightened. Correct this before aligning. (See section 5.16 for
details.)
4. If poor repeatability is experienced
Possible causes include:
› Incorrect or loose bracket mounting
› Significant shaft play or coupling backlash
› Soft foot can cause positioning errors that make repeat measurement
necessary
› Loose anchor bolts
› Yellow knobs on sensor or laser loose
› Temperature changing: machines recently shut down?
› Uneven shaft rotation
› Shaft deflections from coupling strain
