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
