An apparatus, a method and a control system for controlling an industrial robot with at least one axis of rotation and/or translation. The robot includes at least one actuator or motor at each of the axes for driving a movement of an arm of the robot and at least one sensor at each of the rotatable shafts. A dither-signal generator for generation of a periodic signal is used to provide a varying dither signal to a servo of the actuator. Automatic adaption of the dither signal is provided. A computer program for carrying out the method and a graphical user interface.

Control method for a robot

A control system for controlling one or more manipulators. One or more drives control motors driving the movements of the manipulator. An axis computer provides control signals to the drives. A main computer is adapted to execute a program with instructions for the movements and supplies the axis computer with control instructions. Physically separated modules are adapted to be placed at separated locations and to handle different functions. Each module may be surrounded by a casing of its own, may have its own power supply and has a well-defined interface in relation to the other modules. The computers and drives are arranged in the modules. One of the modules is a main computer module, which comprises the main computer. Another of the modules is a drive module, which comprises the axis computer.

Control system and method for controlling one or several manipulators

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.
