8 Operation
WARNING
Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.
9 Maintenance
9.1 Safety
WARNING
Unexpected movement of components
Injury due to impact or crushing.
• Before working on the product: secure the slide to prevent unintentional move-
ment.
CAUTION
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
Injury due to impacts or crushing.
• Bring moving parts of the product into a safe end position or secure them
against falling.
9.2 Checking axis elements
Checking the cover strip
•
Check: every 2000 km.
If waves form, the cover strip must be retensioned.

4. Tighten the screws.
Tightening torque: size 32/45: 0,2 Nm; size 60/80: 0,8 Nm.
If it is no longer possible to retighten the cover strip, the belt reversals and the
cover strip should be replaced

9.3 Cleaning
–
Clean the product with a clean, soft cloth and non-abrasive cleaning agents.
For use with reduced particle emission:
–
Remove abrasion and contamination from the product on the following
schedule:
–
Prior to initial commissioning.
–
Regularly during operation.
9.4 Lubrication
The axis is lubricated for life.
Additional lubrication of the axis is not necessary.

Malfunction Possible cause Remedy
Loud running noises,
vibrations or rough
running of the axis. Torsional stresses
–
Install axis without tension. Make sure that
the contact surface is flat
è
6.3 Mounting
axis.
–
Change the layout of the attachment compo-
nent (e.g. payload).
–
Align axes parallel to each another.
Resonance oscillation
of the axis. Change the travel velocity.
Wear on bearing or
guide.
–
Contact local Festo Service.
–
Replace axis
è
www.festo.com/catalogue.
Vibrations on the slide. Operation at the reso-
nant frequency of the
axis.
–
Change the travel velocity.
–
Change the acceleration.
–
Increase axis stiffness (e.g. shorter support
distances).
–
Change the payload geometry.
Long oscillations of the
profile. Resonant frequency of
profile and payload too
low.
–
Increase axis stiffness (e.g. shorter support
distances).
–
Change the payload geometry.
Slide does not move. Loads too high. Reduce forces and torques. Consider dynamics.
Screws for mounting
the attachment com-
ponent are too long
(e.g. payload). Observe the screw-in depth

tion on attachment component.
Overruns the end posi-
tion. Sensor does not
switch. Check sensor, installation and parameterisation.
Wave formation on the
cover strip or alumi-
nium abrasion on the
axis. Wear on belt reversals.
