Abstract
A method for the safe operation of a machine, which has a movable machine part comprising a hazardous section, comprises: the movable machine part moving according to a predefined sequence program; and an environment of the hazardous section being monitored, wherein, in the event of an engagement of an object into a defined protective volume, which is dependent on the current position of the hazardous section, within the monitored environment, a safety-related reaction is triggered that comprises the movement of the movable machine part being stopped if the engagement exceeds a defined engagement threshold of the protective volume. For a teaching-in of the protective volume, it is provided: that an initial protective volume is first predefined; that the machine is controlled so that the movable machine part moves according to the predefined sequence program while the environment of the hazardous section is monitored; that, if the movement of the movable machine part is stopped as a result of an object engaging into initial protective volume, a teach-in mode can be started by means of a first user input, in which teach-in mode the movement is continued and position data of objects in the environment of the hazardous section are acquired in so doing; that the teach-in mode can be terminated by means of a second user input; and that the protective volume is defined based on the acquired position data.
