Abstract

There is described a method and a device for positioning an element of a machine. A setpoint position variable is generated, said setpoint position variable is reduced by means of a limiting variable and a modified setpoint position variable which is forwarded as a setpoint variable to a controller for positioning the element is formed in this manner. An expected setpoint position variable is determined from the modified setpoint position variable, the braking distance of the element is determined from the expected setpoint position variable, and a braking process of the element is initiated if the braking distance matches a target position which is reduced by the expected setpoint position variable. An element of a machine can so be positioned with accuracy.
