Abstract
Methods and systems for monitoring a dynamic compensation control system of an elevator system are provided. The methods and systems include monitoring a first motion state sensor signal generated by a first motion state sensor, the first motion state sensor associated with an elevator machine, monitoring a second motion state sensor signal generated by a second motion state sensor, the second motion state sensor located on an elevator car, determining an operational status of the second motion state sensor based on an analysis of the first motion state sensor signal and the second motion state sensor signal, and when it is determined that a failure status of the second motion state sensor is present, the method further comprises deactivating a dynamic compensation control mode of operation of the elevator system.
