Operator interface 56 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 by means of the user interface 56 and the

Pre-warning device 52 can 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, the over one

Menu navigation can be selected. 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 signal or interrupted in

Individual signals, e.g. Flashing, short or long individual signals, sequence of individual signals as possible signal sequences and / or e.g. 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 in the range of motion serves the

Advance warning device 52, which gives 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 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 portion 38 or the side cover sections 41.
