Abstract

A method and an arrangement for bringing a load carrier (10; 13) to different predetermined positions along a given movement path. A pulse emitter is provided for generating pulse signals and delivering the signals to a computer unit in which the position of the load carrier is calculated by counting pulses from a reference value. The pulse emitter includes a pulse emitting rail (25; 26) which is provided with pulse markings (30) and extends along the movement path of the load carrier, and a sensor unit (24; 27) which is mounted on the load carrier for movement along the pulse emitting rail and for recording the pulse markings (30) on or in the rail. The detected pulse markings are converted to pulse signals in the sensor unit and these signals are delivered to the computer unit in a number which is relative to the number of detected pulse markings. Each predetermined position is stored in the computer unit as a function of the number of pulse signals received, starting from the reference value and the number of pulse signals received in regard of each position is compared with the number fed into the computer. <IMAGE>
