Expected component lifeGeneralThe expected life of a component can vary greatly depending on how hard it is run.Expected life1) The expected life can also be affected by assemblage of cabling other than standard options.The given life is based on a test cycle that for every axis starts from the calibration positionto minimum angle to maximum angle and back to the calibration position. Deviations fromthis cycle will result in differences in expected life! The life may also be affected by acid oralkaline environment.2) The given life for the balancing device is based on a test cycle that starts from the initialposition and goes to maximum extension, and back. Deviations from this cycle will result indifferences in expected life!3) The robot is dimensioned for a life of 8 years (350,000 cycles per year) in a normal spotwelding application. Depending on the actual application, the life of individual gearboxesmay vary greatly from this specification. The Service Information System (SIS), integratedin the robot software, keeps track of the gearbox life in each individual case and will notifythe user when a service is due. For Foundry Prime robots, working in 100% humidity, otherservice intervalls may be required.The SIS for an M2004 system is described in the Operating manual - Service InformationSystem.
