PURPOSE:To perform a preferable start-up compensation in a rescue operation after an emergency stoppage, by using a start-up compensation value before the emergency stoppage, or a predetermined start-up compensation value based on a signal from a weighing device provided under an elevator box, when the emergency stoppage fakes place. CONSTITUTION:A first start-up compensation torque instruction generating device 82 generates a start-up compensation torque instruction to get a value of a pulse counter 84 closer to a value, of a memory 85, which means a balance point so that the difference between them may be within a predetermined value when an elevator is normally operated and stopped, and then started again. A torque control means 81 controls a motor 6 based on this start-up conmensation torque instruction. A start-up compensation torque instruction memorizing means 87 is connected to the generating means 82, and the start-up compensation torque at the time of starting is stored in the memorizing means 87, and in case an emergency stoppage is generated, an allowance signal is put off to close its normal closed contact 1002, and the start-up compensation torque at the time of previous normal operation stored in the memorizing means 87 is inputted into he means 81 as a start-up compensation torque instruction. |
