1. A method for determining a servicing requirement of axes of a robot arm of an industrial robot, which comprises the steps of:
- making available data of a movement sequence of at least one axis during at least one working cycle of the industrial robot;
determining rotational movements of the at least one axis on a basis of the data of the movement sequence;
determining a servicing interval for the at least one axis by an assessment of the rotational movements;
performing at least one of measuring the data of the movement sequence and reading out the data of the movement sequence from a data memory;
carrying out the assessment on a basis of temporal proportions of a rotational movement or on a basis of a number of revolutions;
using movement sequences of all the axes for determining the service interval; and
determining a common servicing interval for all the axes by the assessment of an axis which, in absolute or relative terms, has a highest assessment.

Abstract
A method determines the servicing requirements of axes of a robot arm of an industrial robot. The data of a movement sequence of at least one axis during at least one working cycle of the industrial robot is made available. The rotational movements of the at least one axis are established on the basis of the data, and a servicing interval for the at least one axis is determined by an assessment of the rotational movements established. A system for determining a servicing requirement performs the method.

6. A system for determining a servicing requirement of axes of a robot arm of an industrial robot, the system comprising:
-
a data module containing data of movement sequences of all the axes of the robot arm during at least one working cycle of the industrial robot; an analysis module for analyzing rotational movements of the at least one axis from the data; and an assessment module for determining a servicing interval for the robot arm by performing an assessment of the rotational movements, said assessment module additionally determining a common servicing interval for all the axes by the assessment of an axis which, in absolute or relative terms, has a highest assessment. - View Dependent Claims (7, 8, 9, 10)
