3.2.3. Expected component life
General
The expected life of a specific component of the robot can vary greatly depending on how
hard it is run.
Expected component life
1)
Examples of "normal usage" in regard to movement: most material handling
applicationsand limited use of bending backwards mode of axis 3.
2)
Examples of "extreme usage" in regard to movement: presstending, very severe palletizing
applications, major use of axis 1 movement and major use of bending backwards of axis 3.
3)
Severe chemical, thermal or similar environments can result in shortened life expectancy.
4)
Depending on application, the lifetime can vary. The Service Information System (SIS),
integrated in the robot software, can be used as a guidance for planning service of gearbox for
the individual robot. This applies to gearboxes on axes 1, 2, 3 and 6. The lifetime of gearbox
axes 4 and 5 is not calculated by SIS (See the
Operating manual - Service Information
System
). In some applications, such as Foundry or Washing, the robot can be exposed to
chemicals, high temperature or humidity, which can have an effect on the lifetime of the
gearboxes. Contact the local
ABB Robotics Service team
for more information.
5)
The given life for the balancing device is based on a test cycle of 4,000,000 cycles that
starts from the initial position and goes to maximum extension, and back. Deviations from
this cycle will result in differences in expected life!
The SIS for an M2004 system is described in the
Operating manual - Service Information
System
. Document number can be found in section
.
For an M2000 system, the SIS is described in section
