Soft foot
If the machine suffers from excessive soft foot, the Move function may be
hampered by the fact that the machine changes its position on its own every time
the bolts are loosened and tightened. Correct this problem before aligning. (Refer
to page 92.)
If poor repeatability is experienced
Possible causes include:
● Incorrect or loose bracket mounting
● Signicant shaft bearing play or coupling backlash
● Soft foot can cause positioning errors that make repeat measurement
necessary
● Loose anchor bolts
● Yellow knobs on sensor loose, or prism not locked
● Sensor is mounted incorrectly or upside down
● Mounted components moved during shaft rotation
● Temperature changing: machines may have recently shut down
● Uneven shaft rotation
● Vibration
