Abstract (en)
[origin: WO2023011832A1] The invention relates to a method for parametrising a model of a manufacturing machine of a manufacturing machine system, wherein the manufacturing machine has at least one axis (X, Y, Z, A, B, C) with a position-controlled drive, by means of which at least a first machine element can be adjusted relative to a second machine element, wherein a maximum movement range, a maximum movement speed for the axis (X, Y, Z, A, B, C) and a maximum electrical power that can be supplied to the drive of the axis (X, Y, Z, A, B, C) are recorded, as boundary conditions for an identification run, in a control device comprised by the manufacturing machine system. The following steps are carried out by means of the control device: - ascertaining or receiving a maximum acceleration and/or a maximum jerk for the identification run; - ascertaining a travel profile for the identification run within the boundary conditions and the maximum acceleration and the maximum jerk for the identification run; - carrying out the identification run according to the determined travel profile; - determining the current (I) supplied to the drive during the identification run; - determining a current limit and/or torque limit of the drive according to a rotational speed of the drive; - determining at least one kinematics actual variable during the identification run; - determining at least one model parameter of at least one model of the axis according to the determined current (I) and the kinematics actual variable; - determining, on the basis of the model and the determined current limit and/or torque limit, at least one trajectory of the axis (X, Y, Z, A, B, C) that is optimised in relation to a minimum travel time or a maximum acceleration or minimum lost energy.
