Abstract
Based on the realization that, at the instant a holding brake in the drive of a machine tool is actuated, it may not be necessary to precisely observe the setpoint values, it may be provided to adapt control parameters in the controller of the drive such that, given an engaged holding brake, oscillations may be avoided or substantially reduced. By applying a correction value to the controller, it may be possible to prevent the adaptation of the control parameters from resulting in a change at the output of the controller.
