ABSTRACT:
A drive arrangement for positioning a positioning element is disclosed that includes an electric servo motor for driving the positioning element, a potentiometer for presetting a setpoint, an actual value sensor disposed at the servo motor, and a motor driver with an integrated evaluation and control unit comparing the setpoint and actual value, whereby a pulse-shaped signal is superposed on the setpoint and the pulse-shaped signal exceeds the motor driver hysteresis in the evaluation and control unit.
