Remedy
Fit the ELFR free of tension
(Pay attention to evenness of the
bearing surface è chapter
Mechanical installation")
Modify travel speed
Send ELFR to Festo for repairs
Reduce load mass
Reduce torques
Check the mounting level of the
proximity sensors, connections and
controller

Note
For the plain−bearing guide (GF), we recommend reducing the acceleration in
order to minimise overswing and increase positioning accuracy.
