Abstract
An industrial robot includes a movable arm and an electric motor driving the arm. A current flowing through the motor is controlled so that the arm is moved into predetermined positions and is balanced in the predetermined positions sequentially. A device memorizes values of the motor current at which the arm is balanced in the respective predetermined positions. A target value of the motor current is calculated on the basis of the memorized motor current values. The target motor current value allows the arm to be balanced in a given position.
