Beschreibung
Zusammenfassung:	A control system for an elevator of the present invention includes a first car speed detection device 11A and a second car speed detection device 11B to measure a moving speed of the car 1, a hoist brake 8 to apply braking to the hoist 3, emergency stop equipment 10 to brake the car by grasping guide rails 9, and a control device 12 to control the hoist 3, the hoist brake 8, and the emergency stop equipment 10 based on outputs of the first car speed detection device 11A and the second car speed detection device 11B. If two pieces of velocity data that have been output from the first car speed detection device 11A and the second car speed detection device 11B respectively differ from one another and acceleration data of the car 1 calculated from one that is higher of the two pieces of velocity data is equal to or more than a predetermined threshold, the control device 12 decides that either the first car speed detection device 11A or the second car speed detection device 11B which has output the higher one of velocity data is abnormal.
