。 AC current supplied from a single-phase power supply through a no-fuse breaker in a general household is rectified into DC current by a converter and a smoothing capacitor, and this DC current is converted into variable frequency AC current by an inverter. In a drum-type elevator that drives an AC motor to operate the car, there is a detection device that detects the current value flowing through the no fuse breaker, and a detection device that detects a current value that exceeds the reference current value. 1. A control device for an elevator, comprising: a control circuit for switching the speed command pattern of the elevator to a speed command pattern lower than a normal speed.
