3.2.4 Expected component life
General
The expected life of a specific component of the robot can vary greatly depending
on how hard it is run.

The expected life of all componets is provided based on the typical cycle.
A typical cycle includes the robot IRB 2600 and track movement, starting from the initial position
(A) and going to maximum extension (B), and back (A). The cycle is a 12-meter movement (from
A to B to A, two 6-meter strokes) in 1 minute with the maximum acceleration 2.5 m/s
payload 1.2 tons. Deviations from this cycle will result in differences in expected life!
The track is dimensioned for a life of 4 years (302,400 cycles per year) in a normal application
two parameters, gliding meters and bending cycles. When maximum limit of either parameter is
reached the complete chain and or cables should be replaced.
In order to maximize the chains lifetime ensure to optimize the software and cell layout to reduce
the amount of travel and cycles.
A cycle is comprised of two strokes / changes in direction.
tracks shorter than 6 meters travel distance do not have gliding contact.
