In a method of operating a cutting machine, a punching machine or the like, with a sensor, which operates in a danger zone of the machine, and with a control device, the control device interacts with the sensor in such a way that, in an active state of the sensor, the intrusion of an object into the danger zone is detected by the sensor and an appropriate object detection signal is transmitted by the sensor to the control device. After receiving the object detection signal, the control device triggers a safety measure, and to ensure that the safety measure is not triggered unnecessarily and to ensure the safety of the operating personnel, the sensor is switched by the control device into an inactive state before the start of a predetermined process step. The speed of danger-relevant machine parts is thereby limited to a predetermined maximum value. |
