Abstract

PURPOSE:To make it possible to stay a cage to the terminal floor constantly even though a regular speed instruction signal of an elevator is output in an error. CONSTITUTION:A deflection between a regular speed instruction signal VN calculated from a regular residual distance RA to indicate the distance from the present position of a cage to the floor to stay, and a terminal floor deceleration instruction signal VS calculated from a terminal floor residual distance RB to indicate the distance from the present position of the car to the terminal floor, is detected by a speed instruction signal deflection detecting means 31. When the value is a set value or higher, the regular speed instruction signal VN is made into a specific value speed instruction signal VH by a speed instruction signal specific output means 32, and output. In a final speed instruction generating means 33, the terminal floor deceleration instruction signal VS and the specific value speed instruction signal Vh are compared, and the smaller side is output as a final speed instruction signal VF.
