Abstract (en)

[origin: EP0893255A1] The actuator is moved by a drive mechanism towards a stop piece especially in the form of a rotary roller. The position of the actuator is detected by a position-indicator. The actuator's drive mechanisms is connected to a motor control and positioned by command(M). At least one auxiliary characteristic line (HK) differing in course from the characteristic line (K) defined by the commands and the position-indicator signals (S) is determined by the motor control during the movement of the actuator towards the stop piece. The command-value used for subsequent positioning procedures is obtainable as a zero position of the actuator fro the values and or course of the at least one auxiliary characteristic line.
