Abstract:
A method for monitoring the operating state of an elevator drive having a brake includes the mounting of a sensor on a movable brake part. The sensor generates an output proportional to the extent of relative movement between the brake part upon which it is mounted and a fixed brake part. The sensor output is monitored to provide an indication of the operating state of the drive and may be combined with other data to provide indications of a variety of drive states.
