loads

Fig. 16 Lubrication interval
2. Read off lubrication interval S
int
è
Fig.16.
The lubrication interval S
int
is dependent on the load acting on the product.
Load factors:
•
Dusty and dirty environment
•
Nominal stroke
>
2000 mm or
<
300 mm
•
Travel profile
Z
triangular operation (frequent acceleration and braking)
•
Ambient temperature
>
+ 40 °C
•
Age of the product
>
3 years
If one of these factors applies, halve the lubrication interval S
int
.
If several factors apply at the same time, reduce the lubrication interval S
int
by
three-quarters.
3. Lubricate the guide and ball screw at all relubrication openings

Malfunction
Possible cause
Remedy
Coupling distance incorrect
Observe the permissible coup-
ling spacings
è
www.festo.com/sp.
Install the axis so it is free of
tension; maintain evenness of
the bearing surface
è
5.1 Mechanical installation.
Change arrangement of the
tool/payload.
Align the spindle axis so that it
is exactly parallel to the second
spindle axis.
Tensions
Change the travel speed
Controller is incorrectly set
Changing the parameters
Squeaking noises, vibrations or
the axis is not running
smoothly.
Insufficient lubrication at guide. Lubricate the spindle axis

7 Maintenance.
Malfunction
Possible cause
Remedy
Guide defective
Squeaking noises, vibrations or
the axis is not running
smoothly.
Guide or cover strip reversal
devices worn
Send spindle axis to Festo or
contact the local Festo service.
Coupling spins.
Check the assembly of the
motor mounting kit
è
www.festo.com/sp.
Load levels are too high.
Reduce load mass/torques.
Slide does not move.
Retaining screws on tool are
too long.
Observe the maximum screw-in
depth
è
Mounting attachments
The reversing backlash is too
large
è
7 Maintenance
The idling torque increases.
Wear
Return spindle axis to Festo for
repair
