Title:
CONTROL DEVICE OF ELEVATOR
Document Type and Number:
Japanese Patent JP2016008093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To correctly adjust a hoist electric motor torque amount at start compensation by directly capturing a riding comfort of a car.SOLUTION: In a control device 20 of an elevator 100 which obtains start hoist electric motor torque from an in-car load by using a relationship between a preset in-car load and hoist electric motor torque, and comfortably maintains a riding comfort at start by driving a hoist electric motor 4 by correcting the hoist electric motor torque, when the in-car load is started in a non-loaded state, a car movement amount is measured from an output of a governor-interlocked encoder 7 attached to a governor 6 which interlocks with the movement of a car 1, and when the car movement amount is out of a preset reference range, the start hoist electric motor torque during start time is corrected by a start compensation torque correction part 23 according to the car movement amount.
