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
Possible cause
Remedy
Uneven movement of the slide
Bearing surfaces dirty
Clean the bearing surfaces
Vibration of the complete system
Check mechanical structure
Faults in the reference travel
Ferritic parts in the vicinity of the
proximity switch
Use parts made of non-magnetic
materials
Incorrect parametrisation
Check parameters in the control-
ler
Squeaking noises or vibrations,
stiffness
Linear axis fitted distorted
Eliminate distortion
Natural vibration in the support
bearings due to resonance
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)
Natural vibration in the side air-
cushion bearings
Change the prestressing in the air
cushion bearing (if necessary,
please consult the Festo service
department)
Effective load too large
Observe maximum values as per
diagram in chapter "Characte-
ristic curves"
Speed too high
Incorrect parametrisation
Check the parameters in the con-
troller by using the FCT paramet-
risation software
Temperature increase due to
loading in continuous operation
Repeat test run under continuous
operating conditions
