A drive unit for electrically operated doors, windows, screening devices and the like, comprises a drive unit casing (5) containing a motion transfer member (4) in engagement with a reversible drive motor (1) with an associated motor control circuit. The drive unit is designed as a program-controlled unit with a microprocessor (6) with an associated reprogrammable memory (7) which contains operating parameters for the drive motor (1) and can be programmed and reprogrammed from the outside via the current supply conductors (8, 9) to the drive unit by means of an external programming device (16) via an interface unit (17) which by connection to the current supply conductors (8, 9) brings these into a programming condition deviating from a normal operating condition and in which data can be exchanged between the microprocessor (6) and the external programming unit (16). |
