PURPOSE:To accurately compensate a secular change in the output of a balancer detecting the extent of load in an elevator cage without adding a special device. CONSTITUTION:This elevator controller is provided with a balancer 13 which elastically supports a car 10 through a rubber vibro-isolator 12, and detects the extent of load in this car 10 after detecting a flexure value of this rubber vibro-isolator 12. An output voltage Vw of this balancer 13 is taken into a microcomputer 14, and the generated torque of an electric motor 5 is operated during the travel of this car 10. In succession, a compensated voltage in the output voltage of this balancer 13 is operated on the basis of this operated torque, thereby compensating the output voltage of the balancer 13. |
