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 detect that there is now an approach to the door 12 and / or a passage readily possible.

The programming or adjustment unit 54 has an operator interface 56 on, by means of an operator, in particular in the course of installation of the door drive 10 Can set control parameters. In particular, the operator interface 56 several input devices 58 such as in particular at least two buttons and a display 60 , in particular a single or multi-digit seven-segment display.

A menu navigation can be done via the user interface 56 also the pre-warning device 52 be set or programmed. In particular, the pre-warning time within which an imminent door operation is warned can be set.

In a preferred embodiment, it is thus also possible to select or set the type, a signal sequence and / or an intensity of the prewarning signal. For example, different signals are pre-stored, which can be selected via a menu navigation. Alternatively or additionally, parameter values for the prewarning signal can be set via menu guides or key inputs or the like. The selection or setting options include z. As visual, acoustic and / or vibration as possible types of Vorwarnsignalen, z. B. continuous prewarning or interrupted in individual signals, such. B. flashing, short or long individual signals, sequence of individual signals as possible signal sequences and / or z. B. Volume or light intensity and / or amplitude of a vibration signal as a possible parameter for the intensity of the prewarning signal.

Tabelle 1 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 and then confirmed by pressing one of the keys. 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.

Table 1

The drive control unit 50 controls a drive operation of the drive device 18 with low energy, leaving the door drive 10 for a low energy operation with a limited impact energy upon impact of the powered door leaf 24 is designed for 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 supervised. If this monitoring results in an increased power requirement of the electric motor 16 , becomes the electric motor 16 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 are necessary for detecting the approach to an obstacle. Accordingly, the door drive 10 designed without additional obstacle sensors.

To reduce a surprise by hitting the powered door leaf 24 on a person in the range of motion serves the Vorwarneinrichtung 52 which issues a pre-warning signal adapted to possible disabilities of the person in good time before a movement of the door leaf.

Since the adjustment or programming must be carried out only during commissioning (for the first time or after maintenance), the door drive control can 20 with the user interface inside a housing part of the door drive which can be removed for mounting or maintenance purposes 10 be accommodated, z. B. below the housing section 38 or the side cover sections 41 ,
