One or more embodiments are directed to an encoder configured to output a signal, and a computing device configured to receive the signal from the encoder and generate a reduced resolution version of the signal, the computing device is configured to transmit the reduced resolution version of the signal to a recipient.

Encoder resolution reduction

A feedback system for a motor of an elevator system is provided. The feedback system may include a first sensor and a processing circuit. The first sensor may be disposed in proximity to a drive component of the elevator system and configured to detect a change in position of the drive component. The processing circuit may be configured to receive a first data signal from the first sensor corresponding to the change in position of the drive component and generate a feedback signal for controlling the motor based on the first data signal.

Position feedback for elevator system

An exemplary device for determining a position of a component moved by operation of a motor includes a rotating member that rotates responsive to operation of the motor. At least one accelerometer is supported on the rotating member. The accelerometer provides at least one of an indication of a tangential force that is tangential to a direction of rotation of the rotating member and a radial force that is perpendicular to the tangential force. A controller determines the position of the component based upon the force indication from the accelerometer.
