integrated in the robot software can be used as guidance when planning gearbox service 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.
The SIS for an IRC5 system is described in the Operating manual - Service Information System.
