Abstract: A tool feeding speed profile is directly programmable, feeding speed minimums across the control blocks being used in advance in the event that the admissible axis dynamics are exceeded by the predefined feeding speed profile. The tool feeding speed profile can be programmed, in particular, as a linear, polynomial, or cubic feeding speed profile, the latter being predefinable over a sequence of control blocks as a feeding speed polynomial or a feeding speed spline by interpolation or approximation.

Abstract: 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.

Abstract: The invention relates to a method for controlling the speed of electric drives, in particular for machine tool controllers, acceleration shocks to the gear mechanism and machine being limited. To this end, control data are read in a multi-block handling procedure and prescribed desired speeds are approached as a speed upper-limit to be maintained as far as possible, and local speed limitations are approached in the form of target speeds at defined target points within the scope of the look-ahead procedure with small acceleration changes within the limits of the maximum permissible jolt. In this context, a speed-independent acceleration limitation can be left at a constantly high maximum value.

Abstract: In a method for a velocity control of electric drives, which permits limiting of the axial accelerations without contouring errors, the required dynamic path limits being determined sufficiently accurately in advance in the vicinity of singular regions by determining the course of the machine axes before the interpolation in an approximate fashion by an approximation via polynomials of higher order and deriving a possibly required local path velocity limit or local path acceleration limit for each control data record with the aid of the global machine axis upper acceleration limits and machine axis upper velocity limits. Otherwise, the feed rate remains constant. The scanning increment for the approximation is variable and is adapted depending on the calculated machine axis loading by scanning the critical regions more finely.
