Abstract: Proposed is an elevator control device in which an unbalance torque estimation unit configured to estimate an unbalance torque in a motor is implemented in accordance with such a new finding that the unbalance torque can be estimated based on a first time period from an output change of a brake state command signal for switching an operation state of a brake from a braking state to a releasing state to a time when the motor starts a rotating operation along with release of the brake, and on a positive or negative sign of a velocity signal obtained when the motor starts rotation. As a result, as compared to the related art, a smaller calculation load can be achieved. Further, the elevator control device can have a sufficient responsiveness for suppressing an influence of the unbalance torque.

Abstract: A production efficiency improvement support system calculates an operational availability and a cycle time, based on results of detection of an operating status of production equipment, and displays a chart. An axis of the cycle time is set to be shorter rightward. The results of detection are displayed in such a mode that variations are recognizable, like points pp1 and points pp2. The points pp1 and the points pp2 have different countermeasures applied for improvement of the production efficiency and are accordingly displayed in different display modes. A point p1 and a point p2 indicating values of an actual cycle time and an actual operational availability are also displayed as representative values of the results of detection. Displaying these indexes in the form of a chart facilitates visual recognition of how to improve the operational availability and the cycle time and effectively supports improvement of the production efficiency.
