The invention relates to a drive assembly comprising a cable drum and a gear motor. Two cables are wound on the cable drum, wherein the end region of the first cable is secured to a first cage part of a gripping cage, and the end region of the second cable is secured to a second cage part of the gripping cage, said cage parts being arranged in a rotatably supported manner about a common rotational axis. A sensor is arranged on the motor for detecting the angular position of the rotor shaft, and the inverter has a signal electronics unit which has a storage device, wherein the sensor is connected to the signal electronics unit, and the signal electronics unit has a comparison means which is designed to be suitable for comparing a first angular value, which is read from the storage device and which is assigned to a first position of the common rotational axis, with the angular value detected by the sensor and deactivating the electric motor on the basis of the result of the comparison, in particular such that the process of winding the respective cable onto the cable drum is terminated upon reaching the first angular value when closing the gripping cage.
