ABSTRACT:
An apparatus and a method for moving an elevator door utilizes computed travel curves to control a door drive. The actual speed and position of the door are inputs to a travel curve computer in which travel curve algorithms are stored. Constants used in the algorithms are freely selectable and are communicated to the computer through a terminal connected to the computer. The computer generates target values a regulator which controls a power unit connected to the door drive motor for the opening, closing and reversing operations of the door.
