The control module includes a position encoder coupled to the fixed belt, a processor electrically connected to the position encoder, and a communications interface electrically connected to the processor and adapted for communication with an elevator controller for the elevator. The control module determines a velocity, a position, and an acceleration of the elevator in response to a count signal output from the position encoder, and calculates a dynamic slowdown distance relative to an elevator landing for each elevator stop. The control module communicates the dynamic slowdown distance to the elevator controller to initiate slowdown of the elevator. The control module determines a new value of said dynamic slowdown distance for each elevator stop.

An elevator system includes an elevator car and a drive unit. The elevator system also includes one or more power sources for providing power to the drive unit, a current sensor and a controller.

The controller is also configured to determine whether the predicted power demand is greater than the available power from the one or more power sources.
