| 发明名称 | Regenerative power control for passenger conveyors | ||
| 摘要 | An exemplary device for controlling power associated with a passenger conveyor motor includes a regenerative drive that is configured to facilitate providing electricity generated by the motor to a power source when the passenger conveyor is moving. The controller determines when an operating condition of the regenerative drive is outside of a desired range and responsively prevents the regenerative drive from facilitating providing the electricity to the power source. | ||

| 主权项 | 1. A device for controlling power associated with a passenger conveyor motor, comprising: a regenerative drive that is configured to facilitate providing electricity generated by the motor to a power source when the passenger conveyor is moving; and a controller that determines when an operating condition of the regenerative drive is outside of a desired range and responsively prevents the regenerative drive from facilitating providing the electricity to the power source, wherein the operating condition comprises current and the controller determines when the current exceeds a threshold. | ||
