The invention relates to a method for the anticipatory speed control, effective over a plurality of blocks, of an electric drive, in an anticipatory analysis of the braking requirements of a plurality of subsequent control data blocks. The braking requirements are necessary for the reliable reduction to the programmed feed rate for the electric drive. The limiting conditions such as admissible track acceleration and block length, are projected onto the necessary braking path, so that the shortest braking ramp determined in each case represents the limiting condition. The braking ramps for a plurality of parametrable override transition values are assigned to each control data block analyzed as characteristic data in a data store. In an interpolator unit, in accordance with an actually preset current override value, an interpolation is carried out between the characteristic data determined in order to determine therefrom the block final speed necessary to prevent excessively rapid travel in the subsequent block.
