Abstract

In a method and device for monitoring a movement-controlled machine, such as a manipulator, having an electronically commutated drive motor for which a commutation angle is provided based on its detected real position and a control variable, in particular a predetermined desired position, a limit value is determined for a rate of change in particular a time derivative of the real position of the drive motor, and the commutation angle is predetermined such that the rate of change of the commutation angle does not exceed a limit value.
