PROBLEM TO BE SOLVED: To make a landing corrective control regardless of the load without using any speed sensor. SOLUTION: An elevator control device is equipped with a door zone sensor, and in accordance with the output from the sensor, a driving motor is speed controlled to serve for the landing corrective operation, and in this control device the elapsed time from the previous completion of the landing corrective operation is recorded. The arrangement further includes a counter and a register for recording the operating direction in the previous landing corrective operation. Judgement is made whether the elapsed time on the counter till the landing corrective control at this time lies within the specified period (102), and if No, control is made with the standard landing control speed pattern (103), and if Yes, the operating direction in the landing correction at this time is compared with the operating direction in the register (104)-if Yes, the car with heavy load is made controllable with the raised speed pattern, and if No, a car with light load is made controllable with a sunk speed pattern. |
