Eliminating faults

Fault Possible cause
Axial play too Wear
large (Care and
maintenance")
Squeaking Distortions
noises or
vibrations vibrations
Incorrect controller settings
Cantilever profile Jamming in the mechanical
does not move end position (e. g. after
reference travel with
excessive speed or prohibited
travel to the end position
during operation)
Loadings too high
Tension of toothed belt in
parallel kit too high
Ambient temperature too low
(increased breakaway torque
in initial run due to increasing
viscosity of the lubricants in
the spindle system)

Remedy
Send EGSA to Festo for repairs
Fit EGSA free of stress
(evenness of support surface: 0.2 mm)
Lubricate cantilever profile
(è 12 Care and maintenance")
Modify positioning speed
Modify control parameters
(only with servo motors)
To release jam manually:
1. Switch off voltage and compressed air
2. Remove motor and coupling housing
3. Turn drive shaft to release it
Reduce speed for reference travel
Provide software end positions, at least
0.25 mm away from the mechanical end
positions (stops)
Reduce load mass
Reduce positioning speed
Send EGSA to Festo for repairs
Reduce tension of toothed belt
(see assembly instructions for the parallel kit)
Reduce load mass
Reduce positioning speed
If necessary, allow higher current with servo
motors (see operating instructions for the
motor)
Adjust ambient temperature
