Abstract: A method for controlling several master axes in a machine, for example a production machine includes the steps of defining profiles of desired values for a plurality of master axes, determining for each master axis a current desired value and also a current desired value for a slave axis using a logic combination rule, controlling a first drive in accordance with the current desired value of the slave axis, and if the dynamics controlling the first drive exceeds an upper dynamics limit, starting at the next clock pulse to modify determination of the current desired values for at least one of the master axes, and controlling the first drive with a reduced dynamics until the reduced dynamics falls below a lower dynamics limit.

Abstract: A control device and a method for controlling several master axes in a machine, for example a production machine, is disclosed. The disclosed method includes the steps of defining profiles of desired values for a plurality of master axes, determining for each master axis a current desired value and also a current desired value for a slave axis using a logic combination rule, controlling a first drive in accordance with the current desired value of the slave axis, and if the dynamics controlling the first drive exceeds an upper dynamics limit, starting at the next clock pulse to modify determination of the current desired values for at least one of the master axes, and controlling the first drive with a reduced dynamics until the reduced dynamics falls below a lower dynamics limit.

Abstract: A method for controlling the rotation speed of a slave drive is described, where a reference rotation speed and a reference position is provided to a controller. The controller determines an estimated acceleration curve for the slave drive based on an instantaneous rotation speed, an instantaneous position and a maximum rotation-speed-dependent acceleration of the slave drive. The estimated acceleration curve for the slave drive is hereby determined so that after a compensation time, the rotation speed of the slave drive is equal to the reference rotation speed and the position of the slave drive is also equal to an expected reference position, which is determined by the controller based on the reference position, the reference rotation speed and the compensation time.
