10.2 Check axis elements
Check toothed belt wear
The pretension of the toothed belt is designed for the entire service life.
Tensioning of the toothed belt is not permitted.
1. ELGA­TB:
– Initial check: after 5000 km.
– Periodic check: every 1000 km.
ELGA­TB­...­F1:
–
Initial check: after 1000 km.
– Periodic check: every 500 km.
2. If there is visible wear on the toothed belt: send the axis to Festo or contact

10.3 Cleaning
Clean the product with a soft cloth. Do not use aggressive cleaning agents.
10.4 Lubrication
Lubrication interval and accessories
NOTICE!
The lubrication interval S
int
is dependent on the load acting on the product.
Load factors include e. g.:
•
Dusty and dirty environment
• Nominal stroke
>
2000 mm or
<
300 mm
• Speed
>
2 m/s
•
Ambient temperature
>
+40 °C
• Service age of product
>
3 years
• Travel profile matches triangular operation (frequent acceleration and brak­
ing)
If one of these factors applies:
•
Halve lubrication interval S
int
.
If several factors apply at the same time:
•
Divide service interval S
int
by four.

the lubricant evenly inside the machine.
11 Malfunctions
11.1 Fault clearance
WARNING!
Unexpected movement of components.
Injury due to impacts or crushing.
•
Before working on the product, switch off the control and secure it to prevent
it from being switched back on accidentally.
WARNING!
Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.
Malfunction Possible cause Remedy
Coupling distance too
short. Observe permissible coupling spacings
è Instruction manual for motor mounting kit,
www.festo.com/sp.
Loud running noises,
vibrations or rough
running of the axis.
Tensions – Install axis without tension. Note the flat­
ness of the contact surface
è 7.4 Fasten axis.
– Change the layout of the attachment com­
ponent (e.g. payload).
– Align axes parallel to one another.
