Abstract (en)
[origin: WO2013127940A2] The invention relates to an electromotive furniture drive (100) for adjusting a moveable part (4, 5) of a piece of furniture (1) by means of an output element, comprising a) at least one adjusting drive (7, 8) with respectively at least one electric motor, a speed reducing mechanism which is coupled thereto and which ensures that the output element is drivenly coupled and can be linearly displaced and/or rotatably moved, and when said output element reaches a predetermined position, said output element actuates an end switch and/or reference switch and/or switching means, b) at least one control device (9) and c) at least one control unit (10), said control device (9) comprising a positioning device for the output element provided with a control block with a counter and a recording device for evaluating impulses of a counter EMK of the at least one electric motor. Said control device (9) comprises a digital potentiometer which emits as an output value, an electric value which is proportionate to the position of said output element. The control device comprises, in a further embodiment, a monitoring device. The invention also relates to a method for monitoring a pulse width ratio of an electromotive furniture drive and a piece of furniture (1).
