In this method for the computation of travel curves, a door control (11) and a door drive (9) participate in the procedure. A lift cage denoted by (1) displays door blades (2), which are driven by the door drive (9) consisting of a motor (3), a first toothed belt (4), a second toothed belt (5), a drive roller (6), a deflecting roller (7) and an incremental transmitter (8). The motor (3) is supplied with electrical energy by a power unit (12) of the door control (11). The incremental transmitter (8) driven by the deflecting roller (7) stands in connection with a second interface (10) of a microcomputer (13). Algorithms, which are implemented in a travel curve computer (14) of the microcomputer (13), control the door drive (9). Constants needed in the procedure are freely selectable and are communicated to the algorithms by means of a terminal (15). The travel curve computer (14) communicates target values and actual values of the door blade position to a regulation (17), which controls the power unit (12) accordingly.
