摘要： A method and system for detecting a predefined level of resistance in motor activated drive systems for activating devices such as roller shutters, rolling gates, jalousies, awnings and movie screens in a predetermined direction or path. The method includes means for sensing predetermined characteristics of the electric motor when the electric motor is activated to move the drive in the predetermined path and detecting a predefined change in the motor characteristics due to the blockage or resistance. The electric motor is deactivated when a predefined level of resistance is detected along the predetermined path which blocks movement of the drive by the electric motor in the predetermined direction for a predetermined time period. The drive is a tubular slide-in drive, wherein the electronic components including the micro controller which is necessary for controlling the stopping is provided within the tubular, and wherein the roller shaft comprises a mechanical play within the tubular slide-in drive of approximately

摘要： By monitoring the load of the electric motor, it can be reliably determined when the electric motor runs up against a stop in the starting position of the awning, etc. The electric motor turns off automatically and resets an internal counter. When the awning, etc., is being extended, a certain number of pulses is counted per rotation of the electric motor, and after a certain predetermined count value is reached, which indicates that the awning, etc., has arrived at end position, the electric motor is turned off. Because the counting device is reset in the starting position, the electric motor automatically compensates for any change which may have occurred in the length of the fabric of the awning, etc., the next time an actuation is carried out.

摘要翻译： 通过监视电动机的负载，可以可靠地确定当电动机在遮阳篷的起始位置等停止时向上运动。电动马达自动关闭并复位内部计数器。 当遮阳篷等延伸时，电动机每转一周计数一定数量的脉冲，并且在达到一定的预定计数值（表示遮篷等）到达终点位置之后， 电动机关闭。 因为计数装置在起始位置被复位，所以电动机在下一次执行动作时自动补偿可能在遮篷的织物长度上发生的任何变化。
