Abstract

Method for optimizing the movement performance of an industrial robot for a current movement path with respect to thermal load on the driving system of the robot, wherein the method comprises the following steps: for at least one component in the driving system, the thermal load is calculated for the whole or parts of the movement path if the calculated thermal load is compared with a maximally allowed load for the component; and dependent on said comparison, a course of accelerations and velocities for the current movement path are adjusted.
