12 Troubleshooting

Warning
Dangerous voltage
Work on a live system may only be carried out by experienced, expert electri-
cal technicians and is only permitted for the purpose of error diagnosis.
For fault-finding in a live system, mobile protective equipment (e.g. a protec-
tive isolating transformer) has to be made available.
Depending on the type of work being carried out and the ambient conditions,
other measures and auxiliary means, such as insulated tools, insulated safety
gloves, insulated location, may be required.
Fault
Uneven movement of the slide
Faults in the reference travel
Squeaking noises or vibrations,
stiffness
65
Possible cause
Bearing surfaces dirty
Vibration of the complete system Check mechanical structure
Ferritic parts in the vicinity of the
proximity switch
Incorrect parametrisation
Linear axis fitted distorted
Natural vibration in the support
bearings due to resonance
Natural vibration in the side air-
cushion bearings
Effective load too large
Speed too high
Incorrect parametrisation
Temperature increase due to
loading in continuous operation
Remedy
Clean the bearing surfaces
Use parts made of non-magnetic
materials
Check parameters in the control-
ler
Eliminate distortion
Increase or reduce the mass, or, if
necessary, increase or reduce the
air pressure supply in the air
cushion bearing (if necessary,
please consult the Festo service
department)
Change the prestressing in the air
cushion bearing (if necessary,
please consult the Festo service
department)
Observe maximum values as per
diagram in chapter "Characte-
ristic curves"
Check the parameters in the con-
troller by using the FCT paramet-
risation software
Repeat test run under continuous
operating conditions
