PROBLEM TO BE SOLVED: To minimize the fluctuation of time in opening and closing a door by controlling the fluctuation of the door opening and closing time caused by an environmental change or the wear or deformation of a movable part by a movable fence itself. SOLUTION: In the opening and closing control of a door, various motor control parameters are set in the motor control part of each movable fence as standard value, and the movement is started according to this value. The time required for ending the control from its start is regularly measured, this value is stored as coefficient, and the value of the motor control parameter is corrected by this door opening and closing time coefficient in the next opening and closing operation of the door to perform the opening and closing control. The door opening and closing time coefficient obtained by the result of this opening and closing control is substituted and reflected to the next control. Accordingly, the control method having the learning function of repeating the control according to the motor control parameter regularly corrected with the latest door opening and closing time coefficient is adapted, whereby the fluctuation of the door opening and closing time caused by an environmental change or the wear or deformation of a movable part can be minimized. |
