Electric servodrives are characterized by precise tracking and its derivations. The way to meet this goal cost them a number of obstacles, whether variations associated with end-stage of astatism, changes in the positioning system parameters or to changes in load torque than the failing values. Problems arise in situations where the link between the servomotor and the load is not driven by "perfect" solid coupling. And the basic rules of control system affected by this phenomenon are given in this article.
