摘要： In an elevator apparatus, a single car is raised and lowered by a plurality of hoisting machines. An elevator control device for controlling the hoisting machines generates speed commands separately for the hoisting machines. When a current value of one of the hoisting machines reaches a current set value, which is set in advance during acceleration of the car, the elevator control device applies the speed command for that one of the hoisting machines, whose current value has reached the current set value, to the other hoisting machine as well.

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.

摘要： In an elevator apparatus, a brake control device has a first brake control portion, a second brake control portion, and a third brake control portion. The first brake control portion operates a hoisting machine brake to stop a ascending/descending body as an emergency measure when an abnormality is detected. The second brake control portion reduces a braking force of the hoisting machine brake when a deceleration of the ascending/descending body becomes equal to or higher than a predetermined value during an emergency braking operation of the hoisting machine brake. The third brake control portion monitors a slip speed of a main rope with respect to a drive sheave during emergency braking operation of the hoisting machine brake, and reduces a braking force of the hoisting machine brake when the slip speed of the main rope becomes equal to or higher than a predetermined value.

摘要： In an elevator apparatus, a brake device stops a car from running. The brake device has a power shutoff portion for shutting off a supply of power to a brake opening coil in response to a brake actuation command, and a current adjusting portion for supplying the brake opening coil with power while adjusting an amount of current in response to a deceleration reduction command from a brake control portion. The current adjusting portion can supply the brake opening coil with power even when the supply of power to the brake opening coil is shut off by the power shutoff portion.

The brake control device has a first brake control portion for operating the brake device to stop a car as an emergency measure upon detection of an abnormality, and a second brake control portion for reducing a braking force of the brake device when a deceleration of the car becomes equal to or larger than a predetermined value during emergency braking operation of the first brake control portion. The second brake control portion controls the brake device independently of the first brake control portion.
