PURPOSE:To promote flexibility of door control and, at the same time, to make it possible to control with high degree of accuracy by comparing the value of a brake stopping counter with door stopping decision data on a gradual decrease curve characteristic specified in advance. CONSTITUTION:ON/OFF signals of a sensor plate and state signals of a door are inputted, operations and phase control of a motor are performed in accordance with input of synchronizing signals, and high-speed pulse signals of the motor are inputted to repeat control against the door. In that controlling method of an automatic door, the value of a brake stopping counter B controlling the stop of the automatic door C is reduced with the time and, at the same time, it is increased by a specific value in the case of inputting of the speed pulse signals A. The value of the brake stopping counter B is compared with door stopping data D on gradual decrease curve characteristic specified in advance, and the stop of the automatic door C is controlled. |
