Zusammenfassung:An elevator system (2, 102) includes a drive system (10) including one or more drive components (11, 13) and drive hardware (15) for controlling the supply of power to the one or more drive components (11,13), a safety chain (16) arranged to break and thus interrupt a supply of power to the one or more drive components (11, 13) unless all of one or more safety condition(s) is satisfied; and a control device (12). The control device (12) is arranged to receive drive information from the drive hardware (15) indicative of a drive system fault; to receive safety chain information from the safety chain (16) indicative of a safety chain break; and to detect and classify a fault in the elevator system (2, 102) using the drive information and the safety chain information.
