Abstract
An apparatus for controlling an elevator comprising control data setting means for setting control data indicative of an environment where the elevator is installed and for generating a control signal representative thereof; cage position detecting means for detecting position of a cage of the elevator to generate a cage position signal representative thereof; cage position converter means connected to receive the control signal and the cage position signal for performing a predetermined logical operation to generate a converted cage position signal corresponding to the environment; position indicator data setting means for setting a position indicator data representing the position of the cage in response to the converted cage position signal generated by the cage position converter means; and position indicator signal producing means for producing a position indicator signal on the basis of the converted cage position signal and the position indicator data. The cage position converter element performs a predetermined logical operation in accordance with the position indicator data and the cage position signal indicative of a floor level of zero detected by the cage position detec…
