ABSTRACT:
Since the elevator type is varied, a set value used for judging car oscillation must be set for each elevator, which requires much time and labor. Also, if the criteria of all elevators are represented by one set value to eliminate the time and labor required for the setting, variations in detection occur. A car oscillation detecting device includes a means in which a set value, which is used as a criterion for judging car oscillation, is stored in advance as a table or a relational expression in which an elevator specification is used as a parameter, and the set value is selected automatically by using the information of the elevator specification, by which the time and the labor for setting are eliminated. Further, since the set value is a value suitable for that elevator, variations in detection can be restrained, and hence the reliability is high.
