Abstract:
Embodiments are directed to calculating a current associated with a motor of an elevator based on an output of a speed regulator, and controlling the elevator based on the current. Embodiments are directed to examining a feeder current obtained via a converter current sensor of a regenerative drive during a peak power condition, and regulating a speed of an elevator based on the feeder current.
