Also, the amount of reversal in the opposite direction at the start of heavy load operation is reduced to provide good riding comfort.

[Problem to be solved by the invention]

By the way, in elevator control devices, the speed command value output from the speed command device affects the ride comfort and landing of the elevator, so it is not sufficient to set and adjust it at the factory stage. Adjustments will be necessary. However, in the conventional elevator control device as described above, at least two operators are required to adjust the ride comfort and landing of the elevator. In other words, the person who checks ride comfort and landing in the car and the person who changes elevator adjustment elements such as variable resistor R3 in the elevator control device communicate with each other through the intercom and make various adjustments to the elevator. This is what is currently being done. For this reason, there was a problem that adjustment work efficiency was poor (and required manpower). This invention was made to solve the above-mentioned problems, and it is possible to adjust ride comfort and other elevator adjustments within the car. It is an object of the present invention to provide an elevator control device that can improve adjustment efficiency.

[Means for Solving the Problems] An elevator control device according to the present invention includes a rewritable storage means for storing elevator adjustment data related to elevator ride comfort 2, floor landing, etc., and a manual operation mode. Means for setting the front elevator control means to data adjustment mode by operating an arbitrary push button on the in-car operation panel while the car is stopped, and a destination floor registration button and door open/close button on the in-car operation panel when in the data adjustment mode. The elevator controller is further provided with means for rewriting the elevator adjustment data in the storage means based on a switch signal associated with the operation of the elevator controller. [Function] In this invention, when the elevator control means is put into the data adjustment mode, the storage means becomes capable of rewriting the elm bake adjustment data by operating the destination registration button and the door opening/closing button on the car operation panel. Therefore, it becomes possible to easily rewrite the elevator adjustment data related to the speed command while confirming the actual ride comfort and landing in the car.
