车库门高度调节方法即是对电动门电机安装计数控制装置的方法，其对电机旋转的角位移量进行计数控制，在电动门安装时根据不同的门高度，确定电机旋转的角位移总量；实际使用时，将电机旋转的累计角位移量计数与安装时确定的角位总量数进行比较，当两者相等时，即电动门上升或下降到安装时确定的位置，便切断电机的电源，使电动门停在预定的位置上，实现了对不同高度卷帘门的控制，避免了采用行程开关进行卷帘门电机控制所存在的不足。 Garage door height adjustment method is installed counting method to control the device of electric door motor, the motor rotating angular displacement quantity to count control, the electric door installation according to the different height of the door, to determine the amount of angular displacement motor rotation; Actual use, install the motor rotating the cumulative amount of angular displacement of counting and determine the Angle of a total number of comparison, when both are equal, the electric door up or down to determine the location of the installation, then cut off the power of the motor, the electric door stop at a predetermined position, shutter control realized with different heights, and avoid the travel switch is adopted to improve the rolling door motor, there exists the shortage of the control.
