Abstract

The invention relates to a method and a control device for moving a machine element of an automation machine by dividing an overall movement of the machine element into separately controlled first and a second movement sections extending in a common direction. Desired values for the first and second movement sections are monitored for compliance with a predefined movement constraint. If the first and/or second desired values fail to comply with the predefined movement constraint, the first movement component and/or the second movement component are changed in an iterative process until the changed first and/or second desired values are in compliance with the predefined movement constraint. The changed first and/or second desired values are stored as new first and/or second desired values for moving the machine element. The method and control device prevent overloading of the drive shafts of an automation machine having redundant kinematics.
