Abstract:
1. A drive unit for a door or a gate comprising: an electric motor; a detection unit for detecting the position of said door or gate, said detection unit being coupled to said motor and providing an identical pulse sequence with every rotation of said motor, wherein the duration of one of the pulses in said sequence is different from the duration of the other pulses in said sequence which have the same duration; a non-volatile memory in which all detected pulses are stored; the electric motor having an electronic control and regulating circuit including an output stage for the electric motor and at least one additional memory, in which an operational program is stored, said program providing a programmable learning procedure upon initial operation for an opening and closing movement of said door or gate, based on said all detected pulses provided by said detection unit; at least one safety device that limits a motor driving torque below a maximum value, whereby the at least one safety device and the electronic control and regulating circuit configure the drive unit for said doors or gates; and a progressively adaptable power transfer module that varies at least one setting set by the at least one safety device during motor operation.
