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,
vibrations or rough
running of the axis.
Coupling distance too
short.
Observe permissible coupling spacings
è
Instruction manual for motor mounting kit,
Torsional stresses
–
Install axis without tension. Make sure that
the contact surface is flat
–
Change the layout of the attachment compo-
nent (e.g. payload).
–
Align axes parallel to each another.
Current controller set-
tings.
Optimise controller data (e.g. velocity, accelera-
tion, ...).
Resonance oscillation
of the axis.
Change the travel velocity.
Wear on bearing or
guide.
–
Contact local Festo Service.
–
Wear of the ball screw
drive.
–
Check reversing backlash
permissible reversing backlash.
–
Contact local Festo Service.
–
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.
Coupling slips.
Check the mounting of the shaft-hub connection
è
Instruction manual for the motor mounting
kit,
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
Ball screw drive
blocked.
–
Contact local Festo Service.
–
Overruns the end posi-
tion.
Sensor does not
switch.
Check sensor, installation and parameterisation.
Idling torque too high.
Wear in the drivetrain.
s
–
Wave formation on the
cover strip or alumi-
nium abrasion on the
axis.
Wear on belt reversals.
–
Retension cover strip
–
Replace belt reversal and cover strip

Disassembly
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
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 attached accessories.
4. Remove motor and mounting kit.
5. Remove the mounting attachments.
6. Observe transport information
