9.2 Cleaning
–
If the piston rod is dirty, clean it with a clean, soft and lint-free cloth without
cleaning agents and then apply the lubricant thinly to the piston rod.
–
Clean the other product components 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.

10 Malfunctions
10.1 Fault clearance
WARNING
Unexpected movement of components.
Injury due to impacts or crushing.
• Before working on the product, switch off the control and secure it to prevent it
from being switched back on accidentally.
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.
Malfunction Possible cause Remedy
Loud running noises
or vibrations or rough
running of the cylinder Coupling distance too
short Observe permissible coupling spacings
è Instruction manual for motor mounting kit,
è www.festo.com/sp.
Torsional stresses
–
Install the cylinder free of tension. Make
sure that the contact surface is flat
è 6.4
Mounting cylinder.
–
Change the layout of the attachment compo-
nent, e.g. payload.
–
Align cylinder and attached guide element
parallel to each other.
–
Use external guide.
Current controller set-
tings Optimise controller values, e.g. velocity, acceler-
ation, etc.
Resonant vibration of
the cylinder Change the travel velocity.
Wear on bearing or
drive screw
–
Contact local Festo Service.
–
Replace cylinder

Insufficient lubrication
of the piston rod Lubricate piston rod è 9.3 Lubrication.
Vibration at the piston
rod Operation at the reso-
nance point of the cyl-
inder
–
Change the travel velocity.
–
Change the acceleration.
–
Increase cylinder stiffness, e.g. shorter sup-
port distances.
–
Change the payload geometry.
Long oscillations of the
profile Resonant frequency of
profile and payload too
low.
–
Increase cylinder stiffness, e.g. shorter sup-
port distances.
–
Change the payload geometry.
Piston rod does not
move Coupling slips Check the mounting of the shaft-hub connection
è Instruction manual of the motor mounting kit,
è www.festo.com/sp.
Loads too high Reduce forces and torques. Consider dynamics.
Threaded drive
blocked
–
Contact local Festo Service.
–
Replace cylinder
è www.festo.com/catalogue.
Pre-tension of toothed
belt too high in parallel
kit Reduce the pre-tension of the toothed
belt
è Instruction manual for parallel kit,
è www.festo.com/sp.
Operation at the lower
ambient temperature
limit
–
Optimise controller data, e.g. velocity, accel-
eration, ...
–
Use gear unit.
Piston rod jammed at
the mechanical end
position Manually releasing a jam:
–
Switch off the controller and lock it to prevent
it from being switched on again unintention-
ally.
–
Remove motor and motor mounting kit.
–
Rotate drive shaft freely.
Overruns the end posi-
tion Sensor does not switch Check sensor, installation and parameterisation.
Malfunction Possible cause Remedy
Position sensing not
reproducible Sensor switches sev-
eral times
–
Contact local Festo Service.
Idling torque too high Wear in the drivetrain
–
Contact local Festo Service.
–

11 Demounting
WARNING
Unexpected movement of components
Injury due to impact or crushing.
• Before working on the product: secure the slide to prevent unintentional move-
ment.
WARNING
Risk of Injury due to Unexpected Movement of Components
For vertical or slanted mounting position: when power is off, moving parts can
travel or fall uncontrolled into the lower end position.
• Bring moving parts of the product into a safe end position or secure them
against falling.
1. Disconnect electrical installations.
2. Remove the mounted attachment component.
3. Remove the mounted accessories.
4. Remove motor and mounting kit.
5. Remove mounting attachments.
6. Observe transport information
