The door drive control device 20 comprises a memory with data for generating a plurality of predetermined sound signals 25, 25a, which may be formed, for example, as a voice signal 25 or as a sound sequence 25a. The predetermined sound signal 25, 25a is generated by reversing the polarity of the electric motor 16 by means of the H-bridge 16a. By alternately and / or periodically braking and accelerating the rotor, the rotor can be set in an oscillating oscillation. This vibration, in particular when it is transmitted to a resonator, can be converted into a user-perceivable sound signal 25, 25a. The resonance body can be formed by the electric motor 16, the door drive 10 and / or the building completion 12 itself.

The door drive 10 after the in Fig. 13 illustrated embodiment includes an interface 31, which serves to drive the door drive control device 20.

The drive control unit 50 receives a door actuation signal requesting a door operation - opening and / or closing - via the interface 31. For example, a switch may be provided in the area of the door 12 which a person desiring passage through the door 12 actuates. But it is also possible that such a signal is requested by means of a remote control not shown via the interface 31.

Upon receipt of the door operating signal, the pre-warning device 52 is activated first, which emits the prewarning signal. The prewarning signal may include any of the previously described acoustic or optical signals. For example, the electric motor 16 is driven in such a way that it generates a specific warning sound, for example sums, or a specific tone sequence. The electric motor 16 can also be controlled such that noticeable vibration occurs in the region of the door, which can be felt, for example, on an adjacent building wall 14. Alternatively or additionally, the illumination device 44 can be actuated to emit an optical prewarning signal, for example by flashing.

If the illumination device 44 is provided with at least one color diode, a permanent or flashing color signal could also be emitted, e.g. Red when a door operation is in progress or imminent.

The prewarning device 52 is arranged such that the prewarning signal at the beginning of a predetermined prewarning time before the door operation, i. a drive movement is initiated is started. Preferably, the prewarning signal stops over the entire prewarning time. It is also possible to give the Vorwarnsignal over the entire time of the door operation until the door has reached its end position.

In the case of a color signal, for example, a color change from red to green could take place. In other cases, by stopping a warning signal, the person can recognize that an approach to the door 12 and / or a passage are now readily possible.

The programming or setting unit 54 has an operator interface 56, by means of which an operator can adjust control parameters, in particular in the course of an assembly of the door drive 10. In particular, the user interface 56 has a plurality of input devices 58 such as in particular at least two buttons and a display 60, such as in particular a single or multi-digit seven-segment display.

Via a menu navigation, the prewarning device 52 can also be set or programmed by means of the user interface 56. In particular, the pre-warning time within which an imminent door operation is warned can be set. In addition, according to the invention, the type, a signal sequence and / or an intensity of the prewarning signal can be selected or set. For example, different signals are pre-stored, which can be selected via a menu navigation. Alternatively or additionally, via menu guides or key entries or the like, parameter values for the Pre-warning signal can be set. The selection or adjustment options include, for example, optical, acoustic and / or vibration as possible types of Vorwarnsignalen, eg continuous warning or interrupted in individual signals, such as flashing, short or long individual signals, sequence of individual signals as possible signal sequences and / or eg volume or light intensity and / or amplitude of a vibration signal as possible parameters for the intensity of the prewarning signal.

The setting can be made in particular via a menu navigation. For example, with one of the buttons, a menu for programming the pre-warning device 52 is selected and subsequently confirmed via another of the buttons. For example, states or switch positions designated as DIL 7, DIL 8 and DIL 9 can be activated or deactivated by the menu in Table 1 below to perform the programming specified in the table.

The drive control unit 50 controls a drive operation of the drive device 18 with low energy, so that the door drive 10 is designed for a low-energy operation with a limited impact energy upon impact of the driven door leaf 24 on an obstacle. In particular, a power consumption of the electric motor 16, a current consumption of the electric motor 16 and / or a Speed of the electric motor 16 monitored. If this monitoring results in an increased power requirement of the electric motor 16, the electric motor 16 is stopped and possibly reversed for a short time. Due to the low energy operation and the monitoring of the power requirement of the drive device 18, no additional closing edge sensors or obstacle detection sensors for detecting the approach to an obstacle are necessary. Accordingly, the door drive 10 is formed without additional obstacle sensors.

To reduce a surprise by hitting the driven door 24 on a person located in the area of motion serves the Vorwarneinrichtung 52, which emits an eventual disability of the person adapted prewarning in good time before a method of the door leaf.

Since the adjustment or programming must be done only during commissioning (for the first time or after maintenance), the door drive control 20 may be housed with the operator interface inside a removable housing for housing or maintenance housing part of the door drive 10, for example below the housing section 38 or the side cover sections 41st
