摘要:
An elevator control device that drives a cage in a high-efficient speed pattern without using a load detector such as a conventional scale device. The elevator control device includes: a current detector for detecting a current that is supplied to a motor from an inverter; a speed detector for detecting a rotation speed of the motor; a speed pattern generator for generating an elevator speed pattern a motor speed control device for controlling the speed so that a speed detection value follows a speed command value of the speed pattern; and a motor current control device for controlling a current that is supplied to the motor with respect to the inverter by using a current detection value and the speed detection value on the basis of the speed command value. The motor current control device has a duty detector for detecting a duty that is a ratio of an on-time of the inverter within a given sampling period, and the speed pattern generator changes the speed pattern of the motor based on a duty detection value detected by the duty detector.
